LONDON: P. S. KING & SON, LTD. ORCHARD HOUSE, WESTMINSTER. 1922 . 1 2 6 u ^ ;^ ^(c> 1^ PREFACE. J The Newmarch Lectures for 1920-1 were given at ^ University College in February, 1921, upon " Current y^ Statistical Problems in Wealth and Industry." They received a publicity in the Press that led to numerous requests for full publication, and I feared from this widespread interest that there might have been some misapprehension on the part of the public as to the character and purpose of the lectures. They were intended to be a detached examination V of the chief statistical data available in the con- sideration of problems of wealth and industry, and an exposition of some principles involved in arriving "^N at those details. Newspaper readers seemed to scent a new supply of powder and shot for current social polemics. In this respect many may have been disappointed. It ^ is with some misgivings that the lectures are now given the permanence of book form, for while the principles have, so to speak, some enduring quality, and it is urgent that they should be better under- V stood, the grounds for more popular interest seem ^ to lie in the illustrations of those principles expressed in current values, which are necessarily quite ephemeral. At a time when the national income is probably decreasing every month (in its monetary expression) at the rate of 100 million £ per annum, any illustra- PREFACE tion based on current values is out of date before the printer's ink is dry, and indeed, however correct it may have been as a rate at a given moment of time, it may never have been correct at all over a period of time to which it relates. It might have been better, therefore, if the illustrative figures could have been drawn from a period of more stable values. The risk of being quoted without context or reserva- tions has, however, been faced, and readers are asked, upon the early arrival of a time when some of the estimates must be manifestly inapplicable to changed conditions, and have no lasting value, to bear these reservations in mind. It may well be some years before a condition of stable values is reached. There is much, therefore, to be said, if such considerations as these are to be published at all, against holding them back until more permanent illustrations of principle can be given. This attempt to outline some of the elementary principles involved in the valuation of National capital and income and the determination of their distribution and their relation to prices, taxation and public debt, necessarily suffers from the defects of lecture form. It is, therefore, with much diffidence and a sense of their shortcomings that the lectures are now embodied in book form. So far as the field of wages is concerned, it is pre- eminently Dr. Bowley's own, and I here acknowledge my full obligations to him for my numerous citations from his work. J. C. S. December, 1921. PREFACE TO THE SECOND EDITION. The kindly reception accorded to this book has been gratifjdng, and the few criticisms have been such as to call for little comment. I should like, however, to take this opportunity of saying that nothing in the Chapter on Taxable Capacity should be taken as suggesting the view that the precise limits are really susceptible of exact measurement by such arithmetical methods, but that, as such attempts are actually being made by others, I have endeavoured to indicate some of the principles and precautions which must be observed if they are to have any approach to correctness of degree, and if the results are to be inaccurate only to the extent of errors in the statistical assumptions.

THE MEASUREMENT OF NATIONAL CAPITAL (i) Introduction: Essential Data to he considered. Any student of current financial and commercial problems will realise that in the discussion of them there are certain boundaries or limits which condition the possible treatment of the subject. We have been, for example, recently made familiar with the idea that there is a limit to taxable capacity. These points represent, so to speak, physical facts which we may deplore but cannot escape, and all our political strategy and economic practice has to be con- formed to them just as military or other action must be limited by geography and topography. Now, although these facts exist, our precise measurement of them is often very faulty, and what is more important still, our appreciation of the exact meaning of our measurements, when we have made them, is also very slipshod ; we ignore real differences of meaning and apply various unlike things to the same problem as 2 WEALTH & TAXABLE CAPACITY though we had already carefully defined them. These essential data of modern discussions include the amount of the national wealth. This, in itself, covers three or four distinct ideas, such as the amount of taxable wealth in the hands of, first, individuals and col- lections of individuals, or, secondly, the State, and, thirdly, the amount that would fall under particular schemes of taxation, " chopping " off sections of wealth at a particular moment of time ; while there are such other concepts as " inventory wealth " and " Hving capital " which have a use for particular purposes. Then we have the national income, which also is capable of several distinct conceptions, and may, or may not, include those classes of income which are not the subject of money payments, or which are not customarily treated as income. Then follows the way in which the above- mentioned wealth or income is divided up amongst individuals ; that is, the proportion of it which goes to certain sections of our population ; the amount of income which is not consumed but is saved ; the amount of it which is made at home, and that which arises from abroad ; the division of wealth into differ- ent categories of ownership, such as the owners of capital, the owners of muscle, and the owners of brain. Then we have the facts about these proportions or measurements, not merely as static problems at a particular moment of time, THE NATIONAL CAPITAL 3 but such dynamic problems as the rate at which they may be altering, and the direction of any change. Further determinable points are now to be found in the requirements of the State for purposes of the National Debt, and, perhaps, also in the amount of individual income or wealth which is available for State purposes without reducing the individual to a state of starvation or of universal ca' canny — in other words, what we now call " the limit of taxable capacity." Other limits of an inexorable char- acter are to be found in the effect of changes of price upon incomes and wealth in relation to tax burdens. (2) The Spirit and Purpose of the Enquiry. Now people would very much rather discuss principles and propaganda, and proposed tactics for social legislation, than do the trying work of examining the statistical data upon which nearly all such discussions are based. These data are tossed about as things given, requiring no further examination, or of which the examination is complete ; whereas until we have thoroughly examined them and know the limits of error in amount to which they may be subject, and their precise character for any particular problem, we are hardly entitled to embark upon the discussion at all. 4 WEALTH & TAXABLE CAPACITY I have been impressed with the great necessity for a better pubHc recognition of the methods and principles involved in getting at these essential data, and of what they really mean. I am, therefore, frankly devoting these lectures to such an examination, and if I may so call it, a popularisation of the purely statistical in- vestigations involved. I think it, for example, highly important that there should be a wider knowledge of the various ways in which the national wealth can be computed — the limits of error, the uses to which the valuations may be put, and the modifications required, accord- ing to the several uses to which they are devoted. I think it essential that we should have a better knowledge of the unescapeable facts about the division of income, and the amounts available for particular purposes. If, therefore, I do not attempt solutions for our great public pro- blems to-day, and you are inclined to accuse me of not being practical on that account, my answer would be that I am trying to be practical in a higher sense, in that I want to understand the real limits to knowledge and discussion, which are a preliminary to these things. As Professor Pigou says in his great book recently published, " When a man sets out upon any course of enquiry the object of his search may be either light or fruit, either knowledge for its own sake, or knowledge for the sake of the good things to which it leads." I do not pretend that the THE NATIONAL CAPITAL 5 facts which we are proposing to examine have any interest apart from their apphcation, but it is a feature of prime scientific importance that we should examine them in the dry light of statistical precision before we proceed to cloud our judgment by application to specific problems in which, try as we will, we must be influenced by prepossession and prejudice. We should be like the man who would not admit that two plus two made four until he was told what use was going to be made of the admission. The statistician who begins with his thesis for social betterment, and then produces his figures to support it, may be perfectly honest, but he is always under the suspicion of having been unduly influenced by the goal at which he is aiming. (3) The National Wealth — the Questions to he Answered. The first cardinal feature for determination is the National Wealth : (i) What is its amount and to what degree of accuracy ? (2) How is it computed ? (3) What does the result mean when we have got it ? (4) What precautions have we to take in appl5dng it ? (5) Are there different figures for different appHcations or purposes ? (6) What are those purposes ? While there is a very considerable literature upon this particular subject — running into some 6 WEALTH & TAXABLE CAPACITY scores of works — it is extraordinary how the less responsible efforts, often mere partisan guesses, gain a footing and keep currency with serious and reasoned estimates. Tliis arises partly from the fact that the partisan who is out to prove his point is nearly always best pleased by an extreme figure, and so we find that current estimates of the wealth of the United Kingdom (in 1914) used in polemical literature range from 10,000 to 24,000 millions £ sterling. (4) The Use of such Estimates. The uses to which Estimates of National Wealth and Income may be put are many and various. They include : — (i) Tests of " progress " by way of comparisons between different years, to show the accumulation of capital ; tests of the distribution of wealth, according to the form or embodiment which wealth takes ; of the effects of changes in the rate of interest, or in the value of money. (2) Tests of the relative " prosperity " or resources of different nations or communities, either as a whole or per head of the population, and in relation to their national debts. (3) Comparisons of income with capital and property. {4) Considerations of the distribution of wealth according to individual fortunes, and changes in that distribution. (5) Consideration of the applicability and yield of schemes of taxation, e.g., the capital levy. (6) Questions relating to War indemnities. THE NATIONAL CAPITAL 7 It is in connection rather with the second, fifth and sixth classes above that the pubHc mind is most exercised at the present moment, and a great deal of careful, as well as careless, work has quite recently been done in this field of statistics.'^ It is, perhaps, hardly necessary to say that the capital wealth or incomes at any given moment is not a sole test of ability to bear indemnities — it is only a partial measure, for the potential wealth in ungotten minerals and resources, as well as the character of commerce and distribution of income, are important factors in the problem. It may, however, be pointed out at once that present values are on a very different scale from those which are being dis- cussed, and the true money measure of present wealth can only be guessed at for some time yet. As I shall show presently, still the best, and, indeed, the only way, to estimate present wealth is to start with the pre-war figures and make what modifications and adjustments the changed circumstances indicate as desirable. Moreover, the pre-war figure is in itself full of importance for comparison and general interest. (5) What is meant by National Wealth ? The wealth of a country may mean either the value of the objects found within its boundaries, or the wealth of the inhabitants, including their • Vide Statistical Journal, May, 1919. B 8 V/EALTH & TAXABLE CAPACITY foreign possessions, and excluding wealth within the country held by people abroad. The con- fusion between these two ideas has played havoc with discussions on such subjects as the " Taxable Capacity of Ireland." It is the latter sense — the wealth of the inhabitants — that is mainly under consideration. That aspect is foremost when questions of taxation are prominent, but there are matters, such as the inalienable wealth of a country in a geographical sense (for warlike purposes) for which the former is important. A colony capitalised from the home country may be poor judged by the wealth of its inhabitants, but rich in its resources and the actual yield within its borders. (6) Kinds of OnDnership. Wealth in private hands is not easy to define exactly, for there are various shades of owner- ship : {a) Absolute personal disposition of the whole value. {b) Trust interests. (c) Collective ownership with only potential specific allocation to individuals, such as the reserves of a company, which may be of higher value than the aggregation of the market value of individual interests therein (as tested by the Stock Exchange difference in prices of the shares with, and without, such reserves.) {d) Collective ownership, without the possibility of individual allocation, social private wealth, such as churches, clubs, etc. THE NATIONAL CAPITAL 9 Similarly, communal wealth is not all of the same degree of " dispersion " in value. [a) City and local property like waterworks, buildings and trams, having a " value " determinable by deliberate comparison with privately owned objects. {b) National property, varying from a museum to a navy. The closeness with which a " market value " can be assigned varies with the class of wealth for, if there is no possibility of a market, one naturally tends towards the adoption of the cost of production or reproduction. Moreover, some of the comparisons of national wealth of different countries are sHghtly impaired by the extent to which the methods employed give different recognition of each class. Until recent questions of taxable capacity, and the yield of capital levies arose, we under- stood national wealth to mean the full wealth of our inhabitants, derived from sources at home and abroad, and also the amount of capital here owned by people abroad, which was not striking, so that earher writers never troubled much to exclude it. (7) Methods of Computing Wealth. There are five distinct methods of computing national wealth in vogue, but different countries do not rely on them equally, nor are they always able to employ them all. They are : (i)^Based on data arising through taxation of income — notably the United Kingdom. 10 WEALTH & TAXABLE CAPACITY (2) Based on data arising through the annual taxation of Capital — notably United States. (3) Based on data arising through taxation of Capital at irregular periods-Death Duties.-Notably Italy and France. (4) The inventory — an aggregation of various forms of wealth built up from various sources, insurance, etc, — Notably France and Germany. (5) The Census. — Notably Australia. We rely chiefly upon the first, but we fortify it considerably by the third, and check large sections of it by the fourth. (8) Recent Estimates. The most recent detailed estimates of capital are those given by Mr. Crammond before the Royal Statistical Society in 19 14, £16,472,000,000, and my own in "British Incomes and Property " (published in 1916), for 1914, of £i4,3i9,ooo,ooo±£i,867,ooo,ooo. The latter was re-examined in 1918 in the " Economic Journal," in connection with the proposals for a capital levy which had brought forth a crop of " estimates " widely divergent. The former was repeated by Mr. Crammond recently with- out re-examination. The estimates by Sir Bernard Mallet and Mr. Strutt given to the Statistical Society in 1915, based on the "multiplier," led apparently to a considerabl}^ lower figure than my estimate, but the difference has now been fairly recon- ciled.* ♦ Economic Journal, 1918. THE NATIONAL CAPITAL ii At the risk of wearying you, I propose to take you, in some little detail, through the main workings for the estimate, briefly indicating the kind of checks upon it, by going over Mr. Crammond's and my own side by side. This will serve two purposes. First, I have undertaken to give you some idea how these things are worked. Secondly, I wish to make the statement once again that Mr. Crammond's estimate contains demonstrable errors in its make up and does not " fit " with the main auxiliary checks we possess. In passing, we shall get a glimpse of some of the chief statistical difficulties confronting us. (9) Estimates by the Capitalisation Method. The Income Tax provides us with some first- hand statistics of values and profits in useful categories, much more useful for our purpose than merely knowing the number of people with incomes of certain amounts. The statistics for each class were given until recent years in the annual reports of the Commissioners of Inland Revenue. The following table sets out the details of the two Estimates side by side, and also the extent to which Mr. Crammond's figures exceed my own : £'ooo omitted. E.G. J.C.S. Deviations. Sch.

Mr. Crammond took 25 years' purchase of the gross Sch. A. Assessment on Lands, whereas it was demonstrable that the average value was not more than 21 years' purchase, although 25 years was possibly applicable to the net assessment . He had not taken sufficient notice of the change in the rate of interest since Giffen's time, of the actual sales taking place in the market, and of the average valuations adopted for Estate Duty purposes for rented property. From the resultant difference of about 210 millions, I allowed for certain special features in Scotland and for an under assessment in Ireland, and for the special value of building lands, serving to reduce the difference — which became 150 millions. In the case of houses and premises generally, Mr. Crammond took 15 years for the gross assessment. I took 14 years for the gross assessment, after making certain adjustments, and 17.4 upon the net, adopting the mean result. The difference for the year taken by Mr. Crammond would have been over 200 millions between us, but as I worked upon a later year with an additional rental of 9 million £ it was greatly reduced, and stands at 27 million £ only. 14 WEALTH & TAXABLE CAPACITY In the small item of other profits, I made a careful analysis of the nature of the income and adopted 21 years, whereas Mr. Crammond kept to an old precedent with 25 years. In the case of farmers, Mr. Crammond adopted the Sch. B. assessment at 8 years' purchase, but as this assessment was notoriously below the profits being made at the time (being just prior to the date when the basis was altered from one- third to the full rent, as the rough equivalent of profits), I preferred to ignore the altogether useless tax figures, and to review the various estimates of agricultural capital made by agricultural writers, and the accumulation of evidence before the Royal Commission on agri- culture, checked by more recent ideas as to the average amount per acre. In taking 340 million against his 140 million, I added 200 millions to his figures. In dealing with Schedule C. or the interest upon Government Stocks, Mr. Crammond fol- lowed Giffen's method by deducting the Consols, and so not allowing the amount of the national debt to swell the total of the national wealth. I followed a course which comes to the same net result, viz., capitalising the whole interest which is the wealth of indi- viduals, but deducting the amount of the National Debt from the value of Government and local property. The gross amount of this property I put at about 1,100 millions against THE NATIONAL CAPITAL 15 Mr. Crammond's 750 millions, but taking the two items together, I have only 97 millions in excess of his figures. In getting the value for Government and local property, I reduced the figures taken by Giffen, Money and others, by eliminating what had been included twice over by previous writers, viz., the value of waterworks, gasworks, trams, etc., the profits of which as trading undertakings are included in the other classified statements of profit for taxation purposes. Mr. Crammond's estimate was 92J millions for quarries, mines and ironworks, whereas I gave 179 for mines only and 37 for ironworks, so that I exceeded him by 124 millions. A glance at the evidence given before the Coal Com- mission and the details of balance sheets and Excess Profits Duty capital show that my figures were very closely justified. Mr. Cram- mond's are demonstrably too low, upon a tonnage basis. The difference is due partly to the fact that the profits of the years taken by him were rather lower, but mainly to the fact that he took 4 years' purchase, and I adopted 9J years after closer enquiry. In the case of Gasworks, Waterworks, Canals, Docks, fishings, etc., and railways, the difference is due solely to the difference of years. For other profits and interest, and for foreign securities, I made a somewhat closer examina- tion, and there are shght differences in the i6 WEALTH & TAXABLE CAPACITY multipliers adopted, but the net alteration is quite small. (b) General Business Profits. My total estimate up to this point exceeds Mr. Crammond's by 366 million £, and it is at this stage they diverge more seriously. Mr. Crammond adheres to Giffen's old classification, " Other public companies " which he takes at 15 years' purchase, and " trades and profes- sions " which are also taken at 15 years, treating one-fifth of the profits as capable of capitalisa- tion. To the profits of trades and professions, he adds one-fifth for omission or evasion. His resultant total for businesses is, therefore, 3,787 millions. Sir Leo Chiozza- Money's method in " Riches and Poverty " was to take the whole class of profits " Businesses otherwise detailed," and to treat one-half as capable of capitalisation at 10 per cent. For the year 1912 taken on Mr. Crammond's estimate, Money's method would give 2,109 millions, a difference of 1,679 millions. If the companies formed half of the whole trade profits, Crammond's method would be equal to the average of 3 and 15 years' purchase or 9 years over all — as a matter of fact, as the companies are a growing proportion, the actual rate adopted is higher. Money's is equivalent to 5 years' purchase over all. The mat ter is so important that those interested should THE NATIONAL CAPITAL 17 read the substance of my own enquiry into it, showing the reason why I adopted an inter- mediate course.* It is quite clear from an examination of ordinary stock investment values in the years 191 1 to 1913, that the average company business was not worth more than II years' purchase of net profits. I first purged the assessment total of its overcharges and reductions, the inclusion of salaries and especially the allowance for " wear and tear." The latter was generally alleged to be insufficient, and therefore, if anything, my capitalisation would on that account be too high. But no effort had been made by others to get a proper basis figure upon which to work. I then added for evasion 17 millions in place of Mr. Crammond's quite excessive item of 44 J miUions. The mean of the two methods gave me 2,770 millions or just over 1,000 millions less than Mr. Crammond's estimate. It must not be forgotten in comparing the number of years' purchase adopted in capitalising profits assessed to Income Tax Schedule D with the rate of interest on Stock Exchange investments, that the most secure part of the profits, that repre- sented by real property, owned and occupied for business, has been deducted and assessed * British Incomes and Property. Chapter XI. {a) There was a great change in the character of Company profits between 1 895 and 191 4. {b) Registration as joint stock companies gave profits an unreal status in capitalisation compared with private ownership. i8 WEALTH & TAXABLE CAPACITY under Sch. A and the number of years' purchase appHcable to the remainder is therefore lower than it would otherwise be, whereas the profit known to the Stock Exchange, except where there were debentures, includes this stabler element. The record of " paid up " Capital of Companies, some 2,700 millions, is, of course, little test of the true market value that we are seeking. We have to deduct the companies in liquidation, and a very large sum for duplication of capital by interholdings, then the value of real property owned, and also all the colliery and other companies that have been dealt with elsewhere separately. Again, much share capital covers holdings in Consols and foreign securities, also separately capital- ised. The total share capital comparable with the figures we are considering is therefore quite indeterminate, but it is very much less, and then we must add, per contra, the declared or secret reserves, and deduct a sum for share capital which covers goodwill no longer existent. The statistics of share capital clearly cannot be brought in aid to confirm or refute the estimates. I have shown that the method of the Census of Production in estimating the capital in manufac- turing industries covered by the Census, gave results which agree closely with those yielded by my method of capitalising the profits.* * Vide Economic Journal, 1918. Also Professor Bowley's Division of the Product of Industry. THE NATIONAL CAPITAL 19 There are no other subsidiary checks for this section taken by itself, except the results of business valuations for the purpose of Estate Duty. Those who inchne to put a high multi- plier to the total figures of assessed profits must remember that over the large field of the smaller businesses, the bulk of the profit represents earnings of management, which are personal and not readily capitalised, while only a small part is interest on capital. Moreover, a certain amount of trading loss may not be reflected in the figures, while the profits make no allowance for " wasting asset " elements. Mr. Crammond has an item of 44J millions of income for trades and professions evading income tax, which was pure guess work based on the ideas of thirty years previously, when evasion was a very different matter from what it became in 19 14. My figure to correspond was a closely and anxiously examined one, viz., 17 million ^. Mr. Crammond's capitalisation gave 133 million £ on this account, and the total difference between us for the capitalisation of business profits is 1,222 million £. The next item is the capital belonging to non-income tax paying classes, which he puts at 1,000 milhons against my 200 milhons, because he had wrongly supposed that, being exempt from income tax, nothing was included 20 WEALTH & TAXABLE CAPACITY on that account in the Income Tax Statistics. My comment in " British Incomes and Property" was as follows : — " It must be clearly understood that this item does not really refer to the savings of the exempt classes. These savings are in savings banks, and provident societies, all of which make investments, or in building societies which have a gross income from real property, and there is hardly any channel of savings which has not been fully represented in the gross income tax assessments already capitalised. Sixty millions of exempt income has already been accounted for at various rates, from fifteen years' purchase upwards, or, say, over i,ooo millions. What remains is the capital value of the stock in trade, implements, and utensils, etc., of small shop-keepers, and workers like blacksmiths, etc. Anyone familiar with the prices at which small businesses are taken over will hardly quarrel with an average capital of £200 for the shops and £100 for workshops. If we take the table on page 63 of the "Statistical Journal," 1910, giving the British Association Committee's estimate of the amount and dis- tribution of income (other than v/ages) below the exemption limit, Vv^e shall find that working capital of this description is confined mainly to classes 25 to 28, 30 and 31. On the most liberal estimate of average capital for the numbers given there, it is difficult to account THE NATIONAL CAPITAL 21 for more than £200,000,000. Approaching the matter in another way, we have in England and Wales about 534,000 shops and licensed houses, of which, speaking generally, those over £40 only will contain income tax payers, leaving 370,000 under £40. Adding for Scotland and Ireland, we may thus account for £80,000,000. Then 400,000 cases of workshops, etc., at an average of £100 and a million Vv'orkers with tools, etc., of an average va.lue of £10, bring the total to £130,000,000. There may also be some forms of investment which escape the gross income tax assessment, but, altogether, £200,000,000 is a sufficient estimate." Under the heading " movable propeity," etc., not yielding income (furniture, etc.), he has 1,000 million £ against my figure of 800 milhon £. This is admittedly most difficult, but everyone who has examined the matter critically, in the light of Estate Duty valuations (which would not have given a higher figure than 200 millions), and what is common know- ledge as to the general ratio of furniture values to rental values, gives results of the lower order. Finally, under the heading of Income from Investments Abroad or from shipping, banking and mercantile services not brought home, Mr. Crammond pats £60,000,000, v/hich he capitalises at 15 years, giving a capital of 900 milhon £. My estimate was 400 milhon £ as at that date. He followed Giffen's earlier 22 WEALTH & TAXABLE CAPACITY work, and as that was full of misconceptions as to the nature of the Income Tax figures, which I have fully shown in " British Incomes," he naturally repeated the error. Hardly any writers have dealt with these foreign income figures without falling into serious technical error. My estimate of 20 millions income was supported by the Chancellor of the Exchequer's estimate of the duty to be derived from the alteration in law which made such income liable to tax, and nothing that has taken place since has shown it to be inadequate. Moreover, if this figure is included with the foreign income shown, the capitalisation I give accords better with the capital abroad independently ascer- tained by Sir George Paish than any other. Under these last four headings my valuation is 4,170 million £, against Mr. Crammond's 6,689 rnillion £, — a difference of 2,519 million £. Unnecessary Conflicts of Statement lead to Confusion. Mr. Crammond's estimate was originally given with practically no supporting evidence, or reasoned discussion, and some of his errors were pointed out at the time by me. He acknowledged the criticism as very valuable, and said he was " glad to accept the corrections." As Sir Alfred Soward and Mr. Willan say in their recent book, " Dr. Stamp adversely criticised the THE NATIONAL CAPITAL 23 estimate, and the author seemingly did not defend it. Mr. Crammond, however, in 1918, reproduced his figure." It must be added that despite renewed criticism of it in May, 1919, before the Royal Statistical Society, when he was accused of not making himself sufficiently acquainted with the character of the original data, Mr. Crammond has continued to give his old estimate without any comment (beyond a disparagement of other estimates) unsupported by evidence. He repeated it in his address on British Finance Policy given to the Institute of Bankers, 28th June, 192 1. This course, naturally, leads to confusion. The most recent example that has come to my notice is Mr. Snowden's book "Labour and National Finance." When he comes to consider how much it would be possible to raise by means of a capital levy, he says " that estimates of the total capital vary very considerably." He refers to my estimate in September, 1918, of the pre-war amount that would have been available for a general levy — 11,000 million £, and my tentative estimate of the war increase of 5,250 miUion £, making 16,250 million £ available for a capital levy. He then says " Mr. Crammond, in a paper read before the Institute of Bankers, June 7th, 1920, estimated the national wealth at the present time as 24,000 million £. He arrived at this figure by taking his own estimate of the pre-war national 24 WEALTH & TAXABLE CAPACITY wealth at 16,500 million £, which he said would represent, in post-war money, 27,500 million £. Mr. Crammond's figure agrees precisely with the estimate made by Mr. Sydney Arnold, namely, that for the purpose of the capital levy the taxable wealth of the country will amount to 24,000 million £. Mr. Pethick Lawrence has based his estimate of the yield of a capital levy on the assumption that the taxable capital of the country is about 15,000 million £. The wide disparity between the lower and higher of these various estimates is probably explained by the inclusion in Mr. Crammond's and Mr. Arnold's estimates of the v/ar-loans as an addition to the capital of the country." " The war-loans," Mr. Snowden goes on to say, " do not represent any addition to the real capital, but it appears to be sound to regard these sums as available for the purpose of a capital levy." He then proceeds to accept Mr. Crammond's estimate and, with an average rate of tax of 14 per cent, to get 3,000 million £ as the yield of tax. It need hardly be said that this loose way of handling the matter gets us no nearer to the real truth, and rather confuses the pubHc. Although Mr. Snowden has had important details in front of him, he has not in any way grasped the immense difference between estimates of the National Wealth taken collectively, and an aggregation of indi. vidual fortunes, a difference which extends far THE NATIONAL CAPITAL 25 beyond the question of the National Debt. The passage serves to show, moreover, that unsystematic and uncritical estimates such as those given by Mr. Crammond, may circulate, and be used on terms, equal — or often, indeed, superior — to estimates into which much careful thought and criticism has been put, and to which every known test has been applied. It is, first, totally wrong to imagine that the national wealth as a whole comes under any proposed levy, and, secondly, quite wrong to treat the War Loan as though it were wholly an addition to the wealth for this purpose. It is true that it is no addition at all to the real wealth of the country, but, on the other hand, it is equally true that only to a hmited extent is it recognisable upon the wealth returns of individuals. The matter was very carefully gone into in the Board of Inland Revenue memorandum,* and it is surprising how small a section of this wealth can be regarded as " coming out " upon individual returns. Mr. Crammond's method of multiplying up an unchecked pre-war estimate by a general fall in currency values, with no reference whatever to the change in the actual market values of securities, and the rate of interest, is too loose and too rough to be treated seriously as a statistical estim.ate at all. • Vide Report and Evidence : Select Committee on Increase of Wealth (War). 26 WEALTH & TAXABLE CAPACITY Against each detailed estimate I have given a figure for the " range of doubt " which expresses the hmits within which the true figure must certainly be found. Thus " gas- works 182 ±18 " means that the value must certainly lie between 164 and 200 million £. Now, in my aggregate, I have given the aggre- gate range of error as 1,867 niillions, which is the figure that would result if all the detailed estimates were wrong in the same direction to the full extent. Everyone acquainted with statistics or probabilities will know that this is an extremely unlikely, indeed, almost im- possible event, so that we may adopt a common principle, and, after squaring each of the details, take the square root of their aggregate, which gives a range of possible error of 860 millions. The upper limit of my estimate is, therefore, 15,179 millions, and it can safely be said that any pre-war estimate exceeding 15,000 millions will put its author into grave difficulties, if he is to reconcile it with all the existing data, and satisfy all possible tests. Now, how this National valuation is con- tradicted or confirmed by the other methods — by what is known as the multiplier and the other checks we have upon parts of it, — will be seen to some extent later, when we have to bring out some questions of distribution, which are bound up with the points I have made already as to the way in which property is owned.* ♦ Vide page 8 THE NATIONAL CAPITAL 27 The Valuation To-day. The next question is : Hoin) do we pass to the valuation at the present day ? Apart from the difficult question of how property may be owned, we have three different possible conceptions of the valuation. First, we could arrive at the valuation to-day by taking the accepted valuation of some previous year as, for example, 1914, and adding to it the value of all additional physical wealth at its cost price, deducting, of course, any physical wealth that disappears or is destroyed, accord- ing to the figure at which it stood in our original valuation. This is the same thing as adding to the original valuation the amount of the capital savings out of current income, as the net amounts actually saved each year. This in- volves no reconsideration of original values in the light of changing money conditions, and cannot be treated as satisfactory for any ordinary purpose. Even before the recent great change in money values it was never the case that the difference between two valuations, say, ten or fifteen years apart, would equal the aggregate amount of net savings for the inter- vening years. That difference might be either more or less than the savings, according to the movement of money values, and the rate of interest. Thus it is dangerous to suppose that the valuation by Giffen of 10,037 millions in 28 WEALTH & TAXABLE CAPACITY 1885, and that of 10,663 millions £ in 1895, reflected an annual amount of saving of only 60 millions, the difference in ten years being 600 millions. The savings were offset by the changes in existing values, just as the whole current profits of a business might be used up if we made depreciation allowances for the changing value of its Balance Sheet assets brought about through the rate of interest. Under a second method we might revalue all the physical assets as at a single moment of time. This is a little paradoxical, because all valuation involves the assessment of a flow of income over a period, and, therefore, valuation at a moment of time may seem to be a con- tradiction in terms. What is really involved is a question of degree leading into the third kind of valuation which, although ostensibly at a given moment of time, endeavours to take the more stable view, and to present a figure which would be approximately true if judged also at a single moment of time at some little distance. This point is of very material im- portance at a time like the present, with rapidly changing values. If we were to seize by an instantaneous photograph, the market prices of shares, etc., as at the 30th June, 1920, and to secure a similar picture to-day (Feb., 192 1), we should see a very material difference, and we should have to make up our minds which is to be regarded as the estimate of national wealth for the year 1920. THE NATIONAL CAPITAL 29 Technical Difficulties in the Present Valuation. There are special difficulties at the present time in the determination of the national capital — they are of two kinds : (i) in the material to be used ; and (2) in the principles involved. Taking those affecting material : First. The taxation data available have been reduced during the war, and some of the classifications previously useful have dis- appeared, at any rate, for a time. Second. The statistics are always two years " behind," and in some senses five. Assessments themselves, for any given year, relate to the actual results of three preceding years (or five in some instances). So the assessment for the year ending 5th April, 1920, may be on the profits of the three years from ist July, 1916, 1917, and 1918 respectively. These figures are the latest available, and they are, as may be seen, hardly emerging from purely war years, heavily charged with special war profits, and no use whatever as a basis for a firm capitalisa- tion for the future. Third. For some time to come the assess- ments to profits will still be reduced by the amount of Excess Profits Duty assessed. If these are really a burden upon profits, then, of 30 WEALTH & TAXABLE CAPACITY course, it is only necessary to add the duty to get a result which represents profits without the duty, but if as so many urge, the burden is passed on, and profits are maintained, then removing the duty should have no effect on the profit. In the case of removal, it might have no effect upon the rate of profit, but might lead to wider trade and a large aggregate profit at the same rate. But with this burden about, as we think, to disappear, it would be bold to forecast the amount of future net profit which can form the basis of capitalisation. Fourth. The assessed value of property is now on a valuation lo years old, owing to the war having interfered with the regular reassess- ment. This may be remedied before very long. But, in any case, it relates to that field of the enquiry in which there is least un- certainty. Fifth. The auxiliary tests are not available. We have had no Census of Production and no capital valuation of land for lo years. The changes in the Death Duty Statistics are very slow in making themselves felt, or in giving such a basis of years that will warrant any close inferences. The multiplier depends upon mortality statistics which have been quite upset by the war. Even such " inventory " methods as the capital put into businesses, mines, railways, etc. are of no value now, since the capital THE NATIONAL CAPITAL 31 sunk is no such criterion of future worth as it may be when gold values have been relatively stable for a long time. Judging cotton mills at "so much a spindle," and shipping at "so much a ton," is a perilous proceeding when such values are changing daily. Difficulties in Principle. But more important still are the questions of principle involved. The points of principle that arise at the present time bring out various difficulties owing to a temporary " hold up " in the normal flow of economic forces. Are we to value houses upon their value as investments to the recipient of rents, or upon the totally different figures which we should get if we took the extraordinary pressure of scarcity values created by an enormous demand focussed upon a very small point of effective supply ? In the case of commodities which, in the economic phrase, have a "highly inelastic demand," the change in price is often out of all proportion to the decrease in supply. A very few motor-cars short of the requirements of the people who are keen on cars, may serve to keep the price very high. On the whole, therefore, it would appear advisable to ignore purely " scarcity " values of things that are saleable commodities, 32 WEALTH & TAXABLE CAPACITY and to cling as closely as possible to investment values over a long period. But investment values in the case of houses are artificially low, because, even with a considerable supply, the cost of the production of houses is very much higher than of old, and rents left normally to themselves without legal restriction, would rise very much in the same ratio as other prices. Thus the capital value of such rents, even with the same multiplier or number of years' purchase, would be pro tanto higher. Of course the multi- pher is actually less. Property generally forms so considerable a section of national wealth that the difference between these two views is material when we come to attack the figures. Secondly, what I have said about valuation at a moment of time, may be illustrated by the very high prices of ships during the war. The profits to be derived from the ownership of a ship were so enormous for the immediate future that the capital value at any given moment represented not merely the anticipated average income over future years, but also the anticipation of a huge and abnormal sum to be received in the immediate future. Thus a ship fetching £400,000 might do so because it was anticipated that it would make £200,000 in the next twelve months whereas its normal value would have been £200,000 for an anticipated yield of anything from £15— £20,000 per annum. Now do we really intend to laix up what I call THE NATIONAL CAPITAL 33 a " stable national capital " with a passing monetary receipt in the nature of income ? Thirdly, take those classes of goods which provide an income of enjoyment or use rather than of money, such as jewellery and fui'niture, Are we to assess them at the present shop value of their equivalents, or to keep them at the figure that they originally cost us ? Here, again, an indeterminate and intermediate course seems to be the wiser for adoption to any one who is seeking some element of stability in his valuation. Furniture is essentially a thing which may rise to great heights of price through an immediate shortage of supply combined with a limited, but intense demand. Fourthly, the valuation of businesses at a time when the future of taxation is so uncertain, and its burden so great, presents special points of difficulty. Is one to capitalise the present earnings accruing to the owner of the business, or the earnings which one imagines will accrue to him after the repeal of a special duty ? Fifthly. It has been the practice to consider national property on conservative lines, viz., its estimated cost written down substantially for obsolescence and depreciation, but to-day we are faced with the fact that the cost of reproduction would be totally different. You will see that apart from the question of temporary shortage, or a fluctuating point of monetary values, we are faced with the question 34 WEALTH & TAXABLE CAPACITY of whether we shall go " the whole hog " in our revaluations, taking a new and assumed stable level of currency of an altogether different kind from that hitherto adopted. If we do not do this there is a mixture of different cur- rency values, which is rather damaging to any inferences we may wish to draw. It is better to take one's valuation on a uniform currency basis, and then to issue the frankest warnings against interpreting the difference between two valuations at different levels as indicative of equivalent change of physical assets. It is quite obvious that it would be possible to get an enormous apparent increase of wealth when the actual objects of enjoyment might be identical, by the simple process of multiplying the currency by the printing press. The False Increase in Capital Values. Some superficial critics alleged that this was what the Board of Inland Revenue did in their memoranda on the " Increases of War Wealth," whereas it was perfectly clear to anybody studying the matter carefully that they were fully alive to the peculiar character of the increases during the war, for they made repeated reference to increased value " as ex- pressed in money.'' I should like to refer to the evidence that I gave before the Committee myself on this point on the following hues : — THE NATIONAL CAPITAL 35 Much criticism centres round the principle of the War Wealth Levy. We are told that at first it was " out to get the profiteers," then we found that it was attacking a wider range, namely, the people who were better off than before the war, and then, lastly, that it was still wider, namely, the people who were not really better off, but only nominally better off. These are precisely the three stages through which the Excess Profits Duty passed. At first, it was a principle to get hold of the people who made profits out of the War ; then when this was found impossible, the absolute principle was freely asserted as the basis, viz., " when so many people are worse off during the war it is only right that those who are better off should pay." But it was soon realised that with the depreciation of the currency the retention of the pre-war standard, and a fraction of the excess amounting to fifteen per cent., left a man still worse off in real income than he was formerly, and the principle was re-stated, as relative, viz., " We are, of course, all worse off, but some are less so than others, and those must bear the brunt of the burden." In writing of the origin of Excess Profits Taxation in other countries, I have shown that hardly anywhere did the " war profit " idea survive the stage of being a mere impetus to action. "No one will accuse me, I think, of having written with any prejudice in favour of taxation 36 WEALTH & TAXABLE CAPACITY by reference to capital // fairly substantial general allowances are made; we may he said to he left with a proposal to tax, in the main, only the third section due to currency depreciation. This is alleged to he very reprehensihle and indefensible in prin- ciple. But is it so clear that it cannot he a just basis in a special emergency ? It might conceivably happen that, owing to a sudden currency expansion, without any trading excess profits having been made or any other kind of accretions to capital, the whole nominal value of existing wealth should be doubled. But it would only be doubled as a whole — taken on individual assets it might be very uneven in its action (for capital values), and, although col- lectively, people were just as wealthy as before, taken individually, they would have changed their relative positions seriously, and some would be much better off than others by the change. Is there any serious objection to such an application of taxa- tion as would pay some regard to this fortuitous change of relationships, and do something towards a restoration of the status quo ? This is very much what is proposed in effect, and the proposal is hardly so ridiculous or invalid in principle as some of your witnesses seem to urge. It is dis- tinctly more equitable than a Capital Levy in this regard." THE NATIONAL CAPITAL 37 The Valuation of Individual Wealth To-day. Now the method pursued for present purposes of a levy has generally been to get not the figure comparable with the national wealth, but the total individual wealth. StiU, the lines are approximately the same, leaving out certain categories. The official return estimated for individuals, as at 30th June, 1919, some 4,000 millions increase — this included items which would be similar if included in a full National estimate, i.e., lands and buildings 430 millions, farmers' capital 290, movable property 450 millions, decreases of 1,075 for individual holdings in Railways and foreign securities, etc. There was very little increase except that created through war loans, which, though they may be added to wealth for individual purposes, are taken off for the nation's wealth, as a debt on its property. But, at the present time, there are at work various economic factors causing great dis- turbances in capital values ; these disturbances work in different directions in different cases, and they do not necessarily affect income in the same direction or in the same degree. Persons who have in the past invested all their wealth in fixed-interest-bearing securities (such as foreign Government loans or debentures of public companies), find that the capital repre- sented by their securities has greatly decreased -»- ;-^ 38 WEALTH & TAXABLE CAPACITY in value. The income, however, remains con- stant and gives no indication of the amount (or even of the existence) of the capital decrease. Again, other persons who have invested their wealth in house property find in many instances a very substantial increase in the value of their capital, but the income derived from it (after making the necessary allowance for the increased cost of repairs) is in many cases smaller than before the war. The decline in the actual income gives no indication of the increase in the capital value ; indeed, it seems to suggest the reverse. One could fairly assume that left alone, property rents could be double their old level, but this double income would be capitalised on a lower basis owing to the rise in interest and in the net result the capital value is probably not more than 1,200 millions greater. While I prefer to give no estimate of capital wealth at the present time for the reasons stated, I should like to add that, in my judgment, it cannot exceed ig to 20,000 million £, and is probably much less. The aggregate of individual wealth has moved from 11,000 millions in 1914 to about 15,000 millions at June 1920. Of course, these are merely expressed in money values — the increase in real or intrinsic values is certainly almost negligible. CHAPTER II THE MEASUREMENT OF THE NATIONAL INCOME. At the outset I must remind you of what I have said aheady upon the main purpose of these lectures, in order that you may not get restless because I stop short of the application of my results to the practical problems of the day. Instead of starting with the data in these controversies as already given, I am con- sidering the data themselves without regard to their subsequent application, to indicate how they are obtained, the extent of their reUability, what they really mean, and the uses to which they can be properly put. We have already considered the National Wealth under, at any rate, one of its aspects, namely, its aggregate before the war and at the present time, and we have now to consider the National Income. This is a much less difficult and abstract conception in many ways, as it does not depend upon difficult questions of valuation, but can be measured by direct arithmetical methods over a fixed 39 40 WEALTH & TAXABLE CAPACITY period of time, viz., one year, with which we are all familiar. Nevertheless, it has difficulties of its own in principle, and it has some of the same difficulties in regard to material at the present time as were considered in the last section. Many of the figures upon which we have to rely at present are heavily charged with war conditions, and some of the most important fixed points cannot be, at the moment, clearly discerned owing to the fog of war, and the rapid change in prices and profits. Ideas of National Income. We have, first of all, to settle what we really mean by the term " National Income," because different people attach to it different ideas. I define it to be the aggregate money expression of those goods produced, and services performed,* by the inhabitants of the country in a year which are, as a fact, generally exchanged for money. Everything that is produced in the course of the year, every service rendered, every fresh utility brought about, is part of the national income. Thus it includes the benefit derived from the advice of a physician, and the pleasure got from hearing a professional singer. Sir Leo Chiozza Money remarks : — " It is some- times argued that if the national dividend were better distributed part of it would disappear, since it consists of the valuation of services * Subject to certain reservations — vide p. 49 ei $eq. THE NATIONAL INCOME 41 rendered to the well-to-do."* I have frequently contended that our method tends to exaggerate the value of services amongst the rich : "It is obvious that if a ring of people like to call their services any given ' value,' there is no real obstacle A., the great surgeon, performs an operation for B., the prima donna ; B. goes to sing at a social function for C, the leading barrister ; C. takes a brief for A. in a lawsuit. Each one is in the habit of selling the particular service to the community at £100, but on this occasion each sends in a bill for £1,000, which is paid, and up goes the national income by £2,700 above its true figure upon any reasonable exchange basis. ..." " Exchanges are going on between people upon one plane for services at a valuation belonging to that plane, and never brought into comparison v/ith values on a lower plane. If there were equal redistribution, that plane of values would not exist. ... If, however, we had a redistribution of existing capital wealth, socialistically, many services would alter in value ; no physician would get differential fees for identical services. But it is a mistake to suppose that the only change would be a reduction of certain values, and, therefore, a reduction in the aggregate. Certain services would rise in value because of the wider * T)ie Nation's Wealth : p. 114 et seq. 42 WEALTH & TAXABLE CAPACITY effective demand. No one can say what the new equilibrium would be — it is an insoluble problem, because only ' broken arcs ' of the demand and supply curves are known to us. "It is, however, as well to remember that we cannot divide up the aggregate and re-arrange it to the same total, like a box of bricks. It is rather more like the cells of an organism. At the same time it is clearly possible to exaggerate the importance of this point, and the figures we have are sufficiently stable and homogeneous in component exchange values for all ordinary purposes."* The National "Heap." I am most anxious that the conception of national income should be a living and real one to you all, and not merely a mass of figures, so, before we leave this, may I put to you a homely and simple and, therefore, perhaps, inexact illustration, which may serve to make the matter more graphic. To many of you the idea will be fairly familiar, to others, perhaps, not so, but if you will really seize it, it will be one key for many other mysteries of production and exchange, and particularly of currency and the payment of war indebted- ness. Will you suppose, that aU the services and goods that are produced by us as a com- * British Incomes : p. 419. THE NATIONAL INCOME 43 munity in a year are all piled in the centre of this room in a great miscellaneous heap. Every one of you, in the work that you do, is putting that work there. It includes the boots and the clothes that are made, the loaves that are baked, the sheep that are reared, the sermons that are preached, the songs that are sung, the physician's advice, the pilot's skill, the banker's knowledge, the business man's services of organisation, the crossing sweeper's service, indeed, everything that can be given by us whereby we have a claim upon the work of our fellow-men who are contributing to the heap, including the services of those who have helped to make the heap larger than it would or could be if we started afresh without the assistance of piled-up capital goods saved from the heaps of former years. Let it be supposed that we have no such thing as money, but that for each contribution we have made to the heap there is given to us a " labour or services ticket " with a claim to draw something out of the heap in return — if you like, for the moment, equiva- lent in its labour or equivalent in its skill, or its sacrifice, to what we have put in. The people who have refrained from an earlier consumption on the faith of their title to later consumption somewhat larger in extent, also have their title to the heap. Now the total of tickets giving titles to the heap will exactly equal the mass in the heap, and when we have all drawn 44 WEALTH & TAXABLE CAPACITY out what we want of other people's products and handed in our tickets, the heap will have vanished. It is true that when we present our tickets, we shall, perhaps, in our demands for a particular thing that is in the heap, exceed the actual supply ; in other cases, we may ask less. There may be fewer loaves put upon it than we want, and, perhaps, more servants and third-rate music-hall songs than there is a demand for, but these are questions of bad anticipation of demand, and we must rule them out for the moment. The point is now, that we cannot, as a whole, get more out of the heap than we have put into it. If we each secretly make up our minds one night to put a little less on and say nothing about it to anyone else, we shall all be amazed to see how the heap shrinks in its mass. On the other hand, if all tackle their job in the spirit of Sunny Jim, there will be a magic magnification before us. A Scotch congregation, anxious to do honour to a beloved parson and show him some mark of their appreciation of his devoted services, sought the most suitable expression for their feelings. After anxious consultations it was decided to present him with a barrel of whisky. As the readiest means of compassing the gift, it was agreed that contributions should be collected in kind, and accordingly an empty barrel was obtained and, at a time and place arranged, the individuals of the flock brought THE NATIONAL INCOME 45 their offerings in vessels of different kinds and duly poured them into the open bunghole, after which the cask was sealed in preparation for the ceremonial of presentation. This great day arrived, with the pomp and panoply of sheriffs, dominies, and ofhcials, and the minister and his family prominent. A most pleasing feature to all was, of course, the necessity for a general sampling of the present, and it was a solemn moment when the senior elder turned the tap. But, lo ! there flowed forth — pure water ! When the brilliant idea occurs secretly to each one alike that the niggardly character of his little contribution will be lost in the general fund of honest work, there is likely to be a surprising result ! Now, what happened in the war ? Suddenly, a very large number of contributors to the heap had to leave off putting things upon it, and to go elsewhere to fight. They had still to be fed and clothed, and so the heap had to be kept up in spite of their absence, as they were still drawing subsistence from it. It is a fact that in paying for the war everything had to come out of that heap unless it could be bor- rowed from other countries. First of all the quantities of life's necessaries in it had to be maintained, and then the character of it had to be vastly altered to include all kinds of armaments and war materials, and the burden of doing this fell upon a comparatively small 46 WEALTH & TAXABLE CAPACITY fraction of the producers. The war could not be paid for and fought out of the heaps of future years, all the talk about making posterity pay for the war notwithstanding. Everything had to come out of current production. All that was available for war was the difference between what people put on the heap and what they took off it. We had, in consequence, the campaign to take off as little as possible — Economy and Rationing. Then came the cam- paign to put on as much as possible — overtime, and lady workers emerging from their own homes and leaving little private or domestic heaps — contributions to the public heap by hun- dreds of wives and young ladies who had never done anjrthing more than make fancy antima- cassars. I am afraid that in a few cases some of the latter forgot that the object was to make the heap bigger, and as fast as they put services on it had what they call a " good time," taking from the heap all sorts of things which they had never had before, in the way of furs, restaurant dinners, and expensive amusements. Never- theless, the principle of addition was clear. Now the actual work of extracting from the heap the materials for waging the war, had to be done by the State, but, by hypothesis, all the con- tributors to the heap had tickets for what they had put on, and, therefore, had the right to clear it right out. The State, which was, of course, our " collective will," came along and THE NATIONAL INCOME 47 took from our tickets a certain proportion, according to its own plan, which gave it a title to the heap, and lessened our own title. This was taxation. But the State found that in this way it could not get enough, and so it had a second way and came to us and said, " If you will give up to us voluntarily, some more of your tickets, we promise, when the war is won, to give you a special and exclusive title to an extra bit off future heaps." This, we called Borrowing and War Loans. Still the fund for the State was not enough. What remained to be done ? We can picture now that the State by stealth in the night printed a number of tickets for which no corresponding goods had been put upon the heap — if you like, twice as many tickets — and then when these came into the market with all the others clamouring for their share of the heap, it was very soon clear that there were twice as many tickets as goods, and in the scramble for the diminishing heap, people quite gladly gave two tickets to secure an article where one would have previously sufficed. Then by the time the whole heap was cleared and all the tickets had changed hands, the equivalent of every unit of the heap was practically twice in tickets what it had been before. The goods and the tickets, instead of cancelling out at their unit values cancelled out only if two tickets were offered in place of one. This third method 48 WEALTH & TAXABLE CAPACITY is what we know as " inflating the currency," and I have given you very crudely the quantity theory of money. Now the State inflates the currency whenever it uses more purchasing power than it has withdrawn by taxation, or borrowing, from the people. It can deflate only by the opposite method, namely, withdrawing from the people more purchasing power than it uses. Thus, with all these tickets in circulation, the Government might each year, by taxation, draw a large number fr-om the purchasers, but when it came to claiming upon the heap for its own purposes, use only a few of them and destroy the rest. Then the number of tickets per unit of goods would become lower than two, and the process would be continued until the original number of tickets were available. Now these tickets are what we refer to as "money," and in " money " I include not only currency notes, but also banking forms of credit. By thinking of all this stream of production in this way, apart from its value in terms of money, you will be able to refer most of the difficult questions relating to national income to a more sensible test than by dealing with it in your mind in the abstract. In my third lecture I shall talk about the distribution of this heap amongst the different purchasers and people who give service. I am now only con- cerned with the measure, in tickets, of its size. We must have a common denominator ; we THE NATIONAL INCOME 49 cannot add weights and lengths and sizes. Books may be heavy, but we cannot add them to coal ; sermons and lectures may be long, but we cannot add them to dress lengths ; songs and concerts can be nice, but we cannot add them to vanilla ices ! This common de- nominator must be our currency, but you will see that the same sized heap can quite easily be expressed by an aggregate of units very widely different from each other according to the number of " tickets " in existence. There are several matters relating to the computation of national income which are matters of principle, formerly negligible, but now of great importance. The Household Services of Wives. First. It has never been the practice to set any value upon the household services rendered by wives to their husbands and homes. If one were evaluating the total worth of all human effort in money — whether such effort were in fact or in custom habitually exchanged for money — no doubt it would be necessary to make an addition under this head. vSo, equally, would it be necessary to evaluate all the services rendered by individuals in their leisure time to themselves where those services have a com- mercial value. For example, the task of putting 50 WEALTH & TAXABLE CAPACITY down linoleum and hanging pictures would be an addition to one's income at the rate which that service would cost if paid for in the ordinary way. But, after all, in these matters one must have some sense of teleology. We can allow as a deduction from income expenses incurred in getting that income, but not the various ways of spending the income itself upon the essentials of life. Therefore, we do not allow as a deduction from income the cost of boots, clothing or food. Similarly, we should not allow the cost of keeping a home, because these are not business expenses. Our instinct is sound, therefore, in calculating the net amount of money that passes over the threshold of the home, but ignoring everything that is done within that home itself in the way of services. It is true that the payment to a domestic servant, while it constitutes an addition to the National Income, is no deduction from the income of the employer ; in this sense, therefore, we have only a question of degree, and the point at which we have hitherto stopped may be regarded as illogical. In " British Incomes and Property " I stated : — " We omit the immense productive services of wives in household duties, of amateur gardeners, of all who spend any effort, outside their main business of money- income or earning, in performing services or making things. If I get the services of a shoeblack, I add two- pence to the national income, but if I black my own THE NATIONAL INCOME 51 shoes and he gives me some tangible article or service, the monej^ measure is the same as before, but the national wealth is greater. We are often told we must not reckon things twice, and this warning certainly covers all pay- ments made to earn and to keep income intact. If a man pays a housekeeper £1 a week for her services out of his income of £200 a year, they figure together in the national income at ;f252, but if he marries her and continues his payment of £1, the national income shrinks by £52. It is imperative that this limitation of the income tax statistics as a representation of the ' national dividend ' be borne in mind." Now, SO long as this convention was thoroughly understood, I think it was hitherto a reasonable one, the evaluation of wives' services being so difficult where not actually subject to a monetary test ; but a great strain was thrown upon it during the war. Obviously, if a million women performed services in industry worth £100,000,000 a year, and a million wives stopped at home, we have an addition of £100,000,000 to the national income ; but if these ladies changed places, the million wives going out to work and earning £100,000,000, while the million women became domestic servants and housekeepers in the homes of the wives instead of being out-workers, and are also paid £100,000,000, we get an addition of £200,000,000 to the national income. If there is an important change in social practice over a long period, this principle might be also of importance, but on the whole I think we are 52 WEALTH & TAXABLE CAPACITY reverting gradually to a stable condition of social practice, and that the balance of ad- vantage is to ignore the difficulties raised by this conventional treatment. Co-operative Incomes. Second, The extension of co-operative trad- ing tends to diminish the national income as we express it, where the actual services and commodities produced and enjoyed are un- diminished. This arises from the fact that in our conception of income at present, we do not include services which have a strong element of " mutuality." Anyone interested in this aspect should read carefully the reports of the Royal Commission on the Income Tax. Public Services and Taxation. Third. Any tendency to have services per- formed by officials paid entirely out of the proceeds of taxation, instead of out of the proceeds of fees and trading charges, tends to swell the amount of the national income. For example, take the services of the telephone for business purposes, ignoring its private use. If this is paid for by fees, they are deducted as a business expense, and do not form a part of profits. But if we were to put the telephone service as a national charge paid for out of the THE NATIONAL INCOME 53 income tax, we should at once transfer it from the class of expense incurred in getting one's income into expenses or ways of spending one's income. Income Tax is not a deduction in computing one's income. The amount of profits assessable and the income received would, pro tanto, be increased, and the whole of the telephone service and salaries would form an addition to, or duplication, of national income. The same applies to any municipal services which assist people to get their incomes, and which can be charged as business expenses, but which are transferred to the rates now generally paid by householders. Such rates are not a deduction for assessing income. Therefore, a tramway service, or a telephone service, or an electricity service, or a market service, used for business purposes, and subsi- dised out of the rates owing to working de- ficiencies, represents something thrown out of the category of business expenses into the category of personal expenses, and tends to swell the national income wrongly. On balance, no doubt, the profit in relief of rates is greater than the deficiencies. The Payment of Interest on the National Debt. Fourth. The foregoing may not seem of much importance, but when we come to consider the present position of taxation in relation to 54 WEALTH & TAXABLE CAPACITY the payment ol interest on debt, we shall see that the same principle is very significant. Every- one who owns less than the average holding of War Loan is, on balance, paying interest to his fellows for their net balance of loans to him. Everyone who on balance holds more War Loan than the average, is receiving interest on money he has lent his fellows. Now, in ordinary life, such transactions would represent an addition to the incomes of those receiving interest, and a deduction from the incomes of those paying interest. If A. lends B. £i,ooo at 5 per cent., A's income includes £50 of interest, but B.'s income is diminished by a charge of £50 for interest. But in the actual way we are now doing it, the individuals owing the interest do not pay it qua interest — they pay it qua taxa- tion, into a common pool out of which the interest is paid. These payments qud taxation are not allowed as deductions by our con- ventional method of computing national income. We take credit for all the pluses, but do not debit the minuses. The £350,000,000 of interest paid by one set of inhabitants to the other, would, if paid as " balance of interest " transactions, have no effect upon the nominal national income, but under our method of paying it out of taxation, we at once increase the national income, and " the bigger the debt the bigger the income." This, therefore, raises the question acutely THE NATIONAL INCOME 55 whether we have a logical definition of income if we ignore payments for taxes to the extent that we have done in the past. Should we not take out all those payments of taxes which are spent, not upon the objects for which we live, in the normal understanding of " hfe," but for such an exceptional object as the war, it being found that such payments come in to be counted again as income elsewhere ? You will remember that in the case of National Capital this is practically what we did. Having counted the debt as income to the holders, we took it from the collective property of the State and indi- viduals remaining. The question now arises whether some such operation should not be performed in computing the national income. The Difference between Excess Profit Duty and Income Tax. Fifth. The preceding question is made all the more acute when we consider the difference in treatment between Excess Profits Duty and Income Tax. For the E.P.D. is a business expense and is deducted before the incomes are computed upon which income tax is paid. Unless we can agree that Excess Profits Duty and Income Tax are, so to speak, convertible terms, and should be treated in the same way — which means that we should add the whole 56 WEALTH & TAXABLE CAPACITY of the E.P. Duty to the existing figures of National Income, or deduct both E.P. Duty and Income Tax and so alter our practice in regard to the latter — we get a really ridiculous position. Suppose that out of a gross income of £1,000,000,000 the State took £200,000,000 for E.P. Duty and £240,000,000 as Income Tax, the State would take in all £440,000,000 of revenue, leaving individuals with £560,000,000, but the National Income would stand at £800,000,000. Now, let the State say " We still wish to take a revenue of £440,000,000, but we will abohsh the E.P. Duty." It then has to raise £440,000,000 upon an assessment of £1,000,000,000, which is a rate of just under 9s. in the £. This leaves the relative positions of the State and individuals as before, but the National Income becomes £1,000,000,000. Any " loading " of the income tax (or rates on households, which are a kind of local income tax) to meet charges hitherto borne out of other kinds of taxes, at once automatically alters the computation of National income. The Treatment of Pensions. Does not this again lead to the view that, with the enormous extent of present expendi- ture, and the present temporary way of meeting it, we must revise our methods and deduct from THE NATIONAL INCOME 57 the gross income, plus Excess Profits Duty, a sum equal to the amount of income paid to individuals as interest which is payable out of taxation ? This amounts to a frank recognition of a distinction between the payment {via taxation) by individuals of interest to others, and the payments for taxation, which are spent in the ordinary way upon the consumable " bene- fits " of life, such as the Navy, the Army, the Police and education rates, and other current ser- vices which we enjoy. If we decide to do this what ought to be done about pensions ? I do not mean ordinary Civil Service pensions, because these may be said to be equivalent to salaries, and the pension system is only an alternative to paying a higher salary to those rendering existing services and leaving them subsequently to look after their own superannuation allow- ance — such pensions must be taken as equiva- lent (plus the salaries) to the cost of present services. But pensions for services definitely in the past, having no present counterpart, stand on a different footing. In this case we have an analogy to the interest which is being paid in respect of entirely past services, and if the pensions are brought into the aggregate of national income, we ought to take the cost of them from the incomes of the income tax- payers. If this is not done, it will be seen that the more pensioners we have the richer we are, and our figures become meaningless. 58 WEALTH & TAXABLE CAPACITY How is National Income Estimated in Different Countries ? There are three main methods : — (i) Statistics of Income Taxation. The value of this method depends on the completeness and efficiency of the tax in question. It is, for example, very different if England is compared with Italy. " Taxation at the Source " ob- viously gives more complete figures, requiring less supplementing from other sources. The extent to which this method covers the field depends upon the exemption limit, or the point at which the tax starts. The Prussian limit of £47 per annum enabled the method to be applied to cover the bulk of the population, but the British limit of £160 did not account for as much as one-half of the total income, or more than one-eighth of the people. The American exemption, still higher, left an even greater proportion to be dealt with by other means. But with all its defects, this method is the only really satisfactory one for dealing with the income of the wealthier section of the community. (2) The Occupational Census Method. — This method is used for dealing with the wage- earning classes and smaller incomes where the income tax statistics do not apply. These classes have Uttle income beyond their earnings, and the average earnings of each class are THE NATIONAL INCOME 59 deteimined as closely as may be, and applied to the number of earners in each class or occupation as given by the Census. The whole value of this method depends, of course, on the accuracy of the Census, and still more upon the care with which wage statistics are prepared and handled. The lower half of the British estimate is determined in this way with very satisfactory material. The same method is adopted for France, but, by the application of averaged earnings, the result is obtained on rougher lines. In France, moreover, the method was applied to businesses and professions in the absence of income tax statistics. (3) " Net Output " or Census of Production Method. — If the total value of work done or goods produced in a year is determined and the values of the raw materials used are deducted the " added value " may be taken to be the fund which forms the people's income. In the British Census of Production, 1907, the " Net Output " was the gross output (selling value) less the cost of materials used. " It expresses completely and without duplication the total amount by which the value (at works) of the products of the industry taken as a whole, exceeded the cost (at works) of the materials purchased from outside, i.e., it represents the value added to the materials in the course of manufacture." It corresponds, approximately, to the balance of a trading account. It 6o WEALTH & TAXABLE CAPACITY constitutes for any industiy tbxe fund from which wages, salaries, rent, royalties and sundry expenses have to be defrayed, the balance being profit (or loss). Mr. Flux showed that the results of the 1907 Census were consistent with the estimates of British National Income obtained in other waj^s. Giffen in 1903 made an estimate by aggregating the value of goods consumed. This method has hitherto been the chief one for the determination of the incomes of the United States. In addition we have : — Interest on Capital. — In a few cases estimates are partly made up, or are checked, by a com- putation of the average yield upon different classes of capital according to the amount of such capital determined in other ways. The Income " Census." — This method has been adopted in Australia for 1914-15 at the same time as the Wealth Census for ascertain- ing National Capital. The Estimate for the United Kingdom. Now for the United Kingdom, we have to take the matter in three sections : — {a) The Income brought under review for Income Tax, including that investment income actually reaching exempt people. {h) Wage earners not liable to Income Tax. (c) Non-wage earners not liable to Income Tax (e.g., small shopkeepers). THE NATIONAL INCOME 6r The Section Liable to Income Tax. With regard to the first section, taking the year 1914-15, we start with the figure of 985.2 millions, being taxable income with an exemp- tion limit of £160, and after allowing for repairs to property, etc., and depreciation of machinery. This figure will be found in the supplementary tables to " British Incomes and Property." First as to what it represents. A large part of it relates to the profits of businesses assessed on the average of the three years 1911, 1912 and 19 13. These were three of the best years of industry, and were succeeeded, prior to the outbreak of war, by some slight decline, the true extent of which, if the war had not inter- vened, we do not know, but the actual profits of the year 19 14, at the rate for the year before the war, can be said to have approximated closely to this figure. They should not have deviated from it by more than a very small percentage. My total estimate of the allowance which has to be made in order to reduce legal profits for this purpose to the commercial profits for that year, was £30,000,000. There are a great number of ways in which people imagine that the two things are different, but these, on closer examination, are found not to affect the statis- tics in the long run. Fourteen of these headings were carefiiUy examined and their true effects 62 WEALTH & TAXABLE CAPACITY shown, and out of them only seven had really any valid effect. They were For true losses, to which full effect was not given by the statistics of assessment... ... £16,000,000 The capital contained in annuities... ... 3,000,000 The expenses of limited companies ... 1,000,000 An annual allowance for costs of pit-sink- ing in coal mines ... ... 2,000,000 The obsolescence of buildings and machinery ... 5,000,000 The depreciation of fixtures and fittings ... 500,000 Expenses of Brewers' tied houses which (at that time) were not allowed as an expense ... 2,000,000 (Say) £30,000,000 All the other kinds of alleged differences are ruled out for three classes of reasons : — (i) Reasons relating to the actual character and method of making allowances, e.g., Bad Debts. (2) The particularist fallacy ; what may be true of some or all the parts separately, is not necessarily true of the aggregate. (3) The fact that differences of treatment in point of time are not at the same stage in every case, and that in the aggregate the differences disappear. The total is reduced by £^30,000,000, but we add to it £17,000,000 for evasion and another £20,000,000 for income abroad not remitted home. This was brought into legal charge in 1914, but it would be unwise to say that the legal change had had its effect upon the assess- ments at so early a date. Consequently, I THE NATIONAL INCOME 63 made a complete addition for it, and the total of 985 millions thus becomes 992 milUons, to which I should add 30 millions for the under- assessment of farmers in 1914, making £1,022 million in all. Professor Bowley, in his lecture on " The Changes in the Distribution of the National Income," gets for this section a total of 1,040 millions, but he starts with an estimate of 1,000 million and makes no allowance for some of the special features to which I have referred above. (( Intermediate Incomes." When we come to the intermediate incomes, the only recent investigation was that by the British Association Committee of 1910, which estimated that there were 4,053 thousand persons in the United Kingdom with incomes not assessed to income tax, who were not generally classed as wage earners, and that their aggregate income was 335 miUions with an average of £84. Dr. Bowley, who was very largely responsible for the Committee's work, brought the figure down to the year 1913 as 4,310 thousand persons with an aggregate income of 364 millions, and an average income of £84! . The British Association estimate proceeded on the lines of taking thirty-one Census occupa- tion groups for which the numbers are known, 64 WEALTH & TAXABLE CAPACITY and assigning to each group an average income with a certain range of possible error. The information as to incomes for the Civil Service, Local Government, the Army and Navy, Clergy, elementary teachers, banks and railway servants, was fairly exact. A good estimate was made by sampling and by questionnaires for clerks and shop assistants. Small farmers were dealt with by way of a reference to the rental values of the farms. For the other classes, careful estimates were made of the probable propor- tions falling within the income tax sphere, and of the average earnings of the remainder. In the aggregate, the range of possible error, or " modulus," as the Committee called it, was not taken as the sum of the m.oduh, but by adding squares and taking the square root of the sum. The result was £284,700,000 i 29,400,000 — a range of just over 10 per cent. This sum was supplemented by the income from investments and property belonging to this class. The Wage Earners. The national Wages Bill has been estimated from time to time by Professor Bowley in great detail. One of his methods is to take the results of the Board of Trade enquiry (the last volume of which came out in 1912) as a basis. The returns from employers were voluntary, THE NATIONAL INCOxME 65 but sufficient information was received from the great majority of trades where the work is done in factories or large workshops, to lead to results accurately representing the average earnings. He sa^^s " There is little risk of error in the statement that the average of the week's earnings in ordinary industry in the Autumn of 1911 was £1 9s. for men (over 20), los. 6d. for lads and boys, and £1 6s. 3d. for all males. (How archaic all these figures seem already !) In default of other information these averages can be applied, with suitable modifica- tions, to other occupations. By this method a table is obtained with average weekly wages under the broad heads of industry, such as textiles, clothing, etc., for both males and females under 20 years, and over 20 years respectively. As an independent computation, the annual average wages bill of the businesses was divided by the average number employed in a full week. These figures, owing to average illness, and unemployment, are 7 per cent, less than the weekly averages. These figures are then linked up with the occupational census with proper allowances for retired workers and casual workers — data for which are derived from the Labour Department statistics, Friendly Societies, etc. The average annual earnings of males occupied in industries worked out at £57 4s. in 191 1, this average being raised by the 66 WEALTH & TAXABLE CAPACITY inclusion of coal mining, and lowered by agriculture. Each industry was obtained sepa- rately and the total for ii million occupied male wage earners brought up to 631 million £, including payments in kind to agricultural workers. Similarly, there was 151 milHon £ for women, with a margin of error greater than in the case of men, but the total concerned was smaller. The 782 million £ resulting was a trifle below other estimates by Sir Leo Chiozza Money, Sir Thos. Whittaker, and the Fabian Society. The amount and risk of error in the total is comparatively small by this method, as the items do not all err in excess or defect, but there are some minuses against some pluses. I should like to interject here that the total number of manual wage earners and, secondly, of the intermediate class, including shop assistants and those assessed to income tax, excluding wage earners, were got at piecemeal in other ways and found to square with the total occupied population. As regards the intermediate section, there are certain auxiliary checks, such as the known values of the shops and business premises occupied by these classes, or the acreage of small farms, which considerably assist in deter- mining the accuracy. The third section overlapped sHghtly with the income tax assessments, but in 19 13 only to a limited extent, viz., about 50,000 persons. THE NATIONAL INCOME 67 Excluding shop assistants, and allowing for an increase in numbers and rates of wages, Dr. Bowley estimated 770 millions in 1913 as the earnings of 15,200,000 wage earners. This duly allows for unemployment, sickness, holidays and irregular work. Dr. Bowley, when estimating the changes in the National Wage Bill from time to time, has found it more accurate to work from a particular year by the application of factors for changes in rates and numbers to get the figures for other years, than to make direct estimates for such years. He takes the year 1906 as the basis of the measurement of change, because in that year special information was collected by the Board of Trade, which they studied together with the Census of Production in the following year. The Aggregate Pre-War Estimate. In aggregating these three sections the first one is the figure of 1,022 million £ for the income tax section, 365 million £ for the inter- mediate section, and 762 million £ for the wages section (excluding those charged to income tax) or a total of 2,149 million £. We have to add the " unearned " income of those with incomes under £160, old age pensions, and certain other small items, amounting altogether to a little over 100 million £. It should be remembered that this figure includes a certain 68 WEALTH & TAXABLE CAPACITY amount of income or yield which does not go to individuals, but to collective bodies such as charities, to the reserves of public companies, and so on. Very careful and detailed con- sideration has to be given to the question of how much should be deducted if we are to get the individual figures, for where we desire to have an aggregate of individual tax-paying capacity, the difference is important. (This matter will be dealt with in discussing the distribution of income, but the warning is given here, as it is so frequently overlooked.) It will be seen that this estimate of the national income before the war of, say, 2,250 millions, is considerably less than the 2,400 millions given by some writers, who, possibly, hov/ever, intend to allow for renewals and depreciations, out of this higher total. As long ago as fifty years there was a " rule of thumb " method of getting at the national income by doubling the amount assessed for income tax. This was rough and ready, but it is remarkable how near the truth it has remained. You will see that in our calculation it is a trifle less than one- half. The rule has been appUed somewhat regardless of adjustments such as I have made to get " pure income," and also of changes in the level of exemption from £150 to £160, but this latter change has served to keep the rule some- where near the truth, for if the exemption limit had remained at ^^150, a larger number of THE NATIONAL INCOME 69 wage earners would have been included in the tax returns, and the national income would not have been quite equal to twice the income tax figure, before the deductions for repairs, etc. You will agree that if the national income is the money expression of the value of national produce after allowing for that part of the produce applied to repairs and renewals, there would be an alternative way of discovering the total value of produce for exchange and con- sumption. This would consist of valuing the total production and deducting therefrom the value of raw materials purchased from abroad, etc., with our existing working capital. The difference would represent the net additional value created and available to be used as income. This very method has been used in the report on the Census of Production in 1907, where the national income is estimated by the addition to the values of goods produced of services and net imports, to give an approximate net profit. The computation was as follows : — INCOME, 1907. I millions. Gross output of industry, mining and agriculture excluding duplication, but including imported materials to value of ;^38o millions . . . . 1370 Carriage, merchanting and retailing of home-goods 430 Duties on home-goods . . . . . . . . 50 Imports ready for consumption, valued at ports . . 220 Duties on carriage, merchanting and retailing of imports . . . . . . . , . . . . 140 2210 70 WEALTH & TAXABLE CAPACITY Brought forward 2210 Subtract exports . . . . . . . . . . 465 Total value to purchasers of material goods avail- '' able for consumption, maintenance of capital or saving . . . . , . . . . . . . . 1745 Subtract maintenance of plant, etc. {£17^ millions) and of consumers' stock (£15 millions) . . 190 Remainder, available for consumption or saving . . 1555 Add value of personal services and occupation of houses . . . . . . . . . . . . 375 Add new investments abroad . . . . . . 100 Total Income . . . . ;f203o While this is admittedly rough, it indicates that the other method cannot be very wide of the truth, and I should think we are perfectly safe in saying that it cannot be wrong by as much as 10 per cent., i.e., the national income before the war could not have been more than £2,450,000,000, nor less than £2,050,000,000, and almost certainly lay between 2,200 and 2,300 million £. THE NATIONAL INCOME TO-DAY. At this date (February, 192 1) we have no very clear idea as to the actual number of people engaged in industry, though, of course, we know how many come within insured classes under the extended schemes. Still less do we know the THE NATIONAL INCOME 71 numbers in the separate industries, and any information we have as to the increase in piece- work rates or time rates is difficult to apply, because these fundamental facts are missing at present. The Census result will help to re- solve many doubts, as it will give us a new and more secure basis on which to work. The lowering of the exemption limit to £1^0 at a time when there has been a general increase of wages has brought a very large number into this class of official statistics. Formerly, the Income Tax statistics were almost clear of weekly wage-earners, but now some four million at least come within the figures. Let us look at the matter very broadly, assuming, what is very nearly true, that there is no information about total wages. Even if we had the task of disentangling the Income Tax figures, it is not easy to determine the overlapping. The most important statistical return yet given — to which reference will be made again — is that rendered to the Royal Commission on Income Tax and included in the Appendix, p. 90, where the total taxable income of the Income Tax- payers for year to March, 1919, is given as 2,072 million £.* To a considerable extent the figure is conditioned by the profits of the years 1915, 1916 and 19 17, which were the average for the * The later figures published in the Report of the Commissioners of Inland Revenue have been substituted for those given to the Royal Commission. 72 WEALTH & TAXABLE CAPACITY assessment — the first two were taxable partly at 50 per cent., but for the most part at 60 per cent., and the last at 80 per cent, on the excess for Excess Profits Dut}^ Now, if the revenue had been obtained by Income Tax instead of Excess Profits Duty, the assessed profits would have been higher by the amount of the Excess Profits Duty, assessed on the average of these three years, unless, indeed, we assume that it was merely added to profits, and not a tax on profits at all. Then the amount of Income Tax evasion was becoming very considerable indeed, far greater than before the war, and between the two, I think the total profits assessable to Income Tax, excluding Excess Profits Duty, could not have been far short of 2,400 million £. Now the Income Tax was supposed at one time to "divide" the national income into approximately two halves, but that was with exemption at £160. From the return 373 milHon £ belonged to the class between £130 and £160, and so the amount belonging to the classes over ;fi6o would be 2,030 milHon £, and if the pre-war ratio between taxable income and total income still held good, the total, after taking away the Excess Profits Duty payments as not actual income, would be some 3,950 to 4,050 million £. But, of course, when quite a large part of the population has, so to speak, marched past the fixed £160 mark, this cannot be a good test, otherwise THE NATIONAL INCOME 73 when decreases in money values had pushed all but one man beyond the £160 mark, we should be assuming that that one man had an income equal to all the tax payers. So a little closer approach is suggested. We know that before the war the " top " 1,240,000 of the population between them had 1,022 million £ assessed. What do the top 1,240,000 receive in 1918 according to this new table ? From a total of . . . . . . 5,747,000 we may take the three classes up to ;^25o . . 4,490,000 leaving . . . . . . . . 1,257,000 and deduct as standing at ;(250 another . . . . . . . . 13,000 We have left , . . . . . 1,244,000 people whose total income is . . . . ;f2,400 million. less the amount appropriate to the classes deducted above . . . . 724 or, 1,676 million £. Now assuming the distrihition of income has remained fairly steady — an assumption to be examined presently — it can be said that the national income has increased in the same proportion as this top section. In this case the total, after deduction of Excess Profits Duty paid, would be in the neighbourhood of 3,650 million £, which was probably much nearer the truth. 74 WEALTH & TAXABLE CAPACITY After these rough approaches, let us try a still closer method, and rely on the official statistics we have as far as they take us, that is for 5,747,000 taxpayers, carrying us deep down into the weekly-wage earning class to include those who are best off amongst them. We have to estimate for the remaindey of the inhabitants only. How many workers were there in 1920 to correspond with the 20,700,000 before the war ? We remember that we had enormous war losses, and a considerable section of the population has been withdrawn from industry by death and disablement. We also know that the volume of production in 1920 was still far below the good trade years 1912 and 1913, but, of course, we can put this down to a lower average output per person. Against these evidences of reduced numbers we can urge the natural increase of the population, the cessation of emigration, the fact that the tide of new female labour set up during the war, has by no means fully receded, and the still more obvious evidence of the intense pressure upon our existing housing accommodation. vSome may fairly conclude that the number of incomes is not less than the old figured of 20,700,000, and may well be greater. Let us assume for the moment it is the same — what is the average income of the 14,903,000 ? If we plot out the facts on a Pareto line — and there is no good reason for distrusting its THE NATIONAL INCOME 75 indications altogether— the 20,700,000th wage would fall at £83 — and the average income of the class " £8^ to £130 " would be almost £93, giving an aggregate for this whole class of £1,430,000,000, and a National Income of about 3,500 to 3,600 million £. Now I am disposed to think the Pareto index would be rather higher, except for a very poor section not receiving wages, and that the average wage will be nearly £100, making the total 3,600 to 3,700 million £ for 1918-19. As regards the movement of profits since 1918-19, the total Income Tax assessment for 1919-20 was in the neighbourhood of 2,200 millions and probably some 100 millions of the difference applied to weekly wages, so that I feel that we may put the National Income conjecturally (computed on the old principles) at 3,900 milUon £. Now this may easily be 200 or 300 millions out, but my feeling is that it is certainly not less than 3,700 millions and may possibly, though it is not likely, be over 4,100 million £, although estimates made b}^ way of guesses at the present compared with pre-war production raised by the index number of prices lead to higher results. Sir Leo Chiozza Money gave an estimate of 3,610 million £ to the Royal Commission on Income Tax for 1920, arrived at by a direct estimate of wage earners' incomes, and in which he included 350 million £ for Excess Profits Duty, 76 WEALTH & TAXABLE CAPACITY so that he was somewhat lower than my figures. I criticised some of the items and the principles adopted, but did not dissent materially from the final result. Allowing the Excess Profits Duty as a deduction at the end is roughly equiva- lent to the principle for which I have contended, viz., to reckon the full income as assessable, but to allow a deduction for so much of the taxes paid as would be utilised for war loan interest and brought again into the incomes assessed. CHAPTER III THE DISTRIBUTION OF CAPITAL AND INCOME. We have now to consider how wealth is held by different proportions of the population, and how this holding is changing. It is only of recent years that we have been able to form reasonably accurate ideas upon the subject, but now, thanks to the super-tax and the system of abatements that have obtained in the last few years, we can divide the total assessed income into groups which fit all the data so exactly that one can, for ordinary purposes, quite afford to ignore any possible margin of error. Scientific Spirit Essential. My usual preface is, I am afraid, particularly necessary on this occasion. You will realise that, in asking what we know statistically on this subject, we are getting much nearer than we have so far ventured to the real problems and polemics of the day. Some will be eager 77 78 WEALTH & TAXABLE CAPACITY to draw what, according to their pohtical and social leaning, they consider to be inevitable conclusions, and to use them in support of their ideas for improving the world, or pre- venting it being destroyed. I have no concern here with that part of the matter, as the task of examining the facts in as colourless and as dispassionate a way as possible and without the inevitable leanings that come from pre-conceived though honest policies, is a task quite enough to fill the place and time of a Newmarch Lecturer, and better in keeping with his academic surroundings. Tests of Distribution. Time need not be greatly taken up with the question of methods of testing or expressing changes in distribution. All the simpler statis- tical terms have their drawbacks. The handy " average " is not much to lean upon — the average rises when the whole mass of money income rises, without any relative changes in the parts or proportions. The average may remain the same even though there are im- portant changes in distribution over a period. For example, there may be an extra income of £100,000 balanced by 1,000 incomes which have been reduced by £100 each — and this would give no change in the average. Again the mode is useless, and the distribution does not follow the " normal law of error," like a DISTRIBUTION 79 natural or biological series — lha,t is wuh a curve like a cocked hat or sugar loaf — but is asymmetrical to a degree. The median or middle person of the series tells us little, though if we combine it with the upper and lower quartiles we get a much better notion of the facts. Thus, if we say roughly that the person occupying- a place along the scale one quarter up the series has an income such and such a fraction of the income of the middle person of the series, and that the per- son three-fourths of the way up has an income so many times the middle one, we can get a fair test of the distribution at one time com- pared with another, because it is a good measure of the slope, like Pareto's line. A view that, I believe, is shared by Dr. Bowle}^ is that a good way to measure social changes over a period of time is to fix on the upper decile (i.e., the man who stands one-tenth of the way down the series) and examine the conditions always at that point. Before the war the upper decile was just on the border line of being liable to income tax. I think to-day too, with the revised limits of exemption for " man and wife," he is in about the same position. But for present purposes we shall keep mainly to percentages, i.e., that such a percentage of the total number receives such a percentage of the total income, and this method, I hope, will satisfy you all. 8o WEALTH & TAXABLE CAPACITY Pareto's Line I should explain that in the Pareto test we take statistics of the number of incomes above certain amounts something in this way. On a squared sheet we plot the high incomes up at the top left hand, showing on a level with the vertical scale at £100,000 the number of incomes above that figure ; then on a level with £10,000 the total number above that, and so to the smaller incomes and much larger number of persons. When these points are joined they will be found in a Pareto distribution to lie practi- cally on a straight line. The details plotted are not the actual numbers, but the logarithms of the numbers. If we plot the actual numbers we get a curve, but taking the logarithms of the numbers gives virtually a straight line, which enables us to fill up any particular gap or ascertain intermediate points. If you look at this Pareto line, the dotted line illustrates the straight line and the black line the actual statistics of incomes as given in the returns to the Royal Commission on Income Tax, and you will see it exhibits a tendency to fall off when it gets towards impossible or " inhumanly " high incomes. The little differences between the actual and the straight lines may be either technical or genuine deviations from the true Pareto line ; we do not know. It is introduced here to show you one of the simpler ways of DISTRIBUTION 8i w S O u »— I b O C/3 W CQ b O Vi S H < O O ^ CO
