The International Accounting Committee concluded that the assumption Marvin M. Duepree, "Translating Foreign Currency Financial Statements to U.S. Dollars , " Financial Execut ive , XL, No. 10 (October, 1972), p. 49. 22 In the present case, peakedness is not as important as skewness. The more peaked the less difficulty dichotomizing firms for accounting purposes. The flatter the curve the greater the chance that more than two categories of firms exist which are significantly different for accounting purposes. The less skew the distribution, however, the greater the number of exceptions to the "general case." The researcher's own perception of the situation, expressed by the extreme skewness and kurtosls in Figure 1, is that a near nominal scale applies to those characteristics of the firms which have direct accounting consequences. That is, firms either do or do not exhibit a particular characteristic, and for those that do a higher degree possessed merely makes the arguments advanced stronger. 13 that subsidiaries exist to provide cash to the parent is no longer tenable for multinational enterprises. -* Parkinson states: Looked at from the point of view of a Canadian parent, in a typical situations no part of its investment in a foreign sub- sidiary can be regarded as current. (A possible exception might be represented by surplus funds held by the subsidiary awaiting remittance to the parent.) That is to say, for all practical purposes, none of the current assets or liabilities appearing in the balance sheet of the subsidiary is about to be converted to Canadian currency or remitted to the parent; for this reason the working capital held by a foreign subsidiary represents as much a permanent investment by the parent as do the non-current bal- ances held by the subsidiary. f Given the available evidence, only one conclusion appears tenable with regard to the direct relevance of exchange rates for firm valuation. Unless there is substantive evidence that a firm is not described by the general case, i.e., the firm clearly falls in the left-hand tail of the distribution in Figure 1, they are only directly relevant to transactions involving actual currency conversion or to valuation of particular assets and liabilities when conversion in the short-term is reasonably assured. In other words, if objec- tive evidence is present that a portion of cash will be remitted as dollar dividends or that a particular liability will require a conversion of U.S« dol- lars prior to settlement, exchange rates as conversion prices are directly rele- vant to valuing the asset or liability. If in a reasonably short time a con- version of foreign currency is to take place then it is consistent with accrual accounting to apply an expected price or exchange rate to valuation of the item.. *" J Commit tee on International Accounting, p. 151. 9 A ^Parkinson, p. 79.

The information provided directly by exchange rates relates to activity in a particular market, a market with which a multination- al firm may have only limited dealings. Indire ct Rel evance While exchange rates as conversion prices do not appear to be environ- mental variables directly relevant to translation, they might be indirectly relevant in the sense of reflecting the relative economic value of currencies. That is, exchange rates may constitute approximations of the relative values of currencies in acquiring goods and services, and so reflect the relative cost- price structures of economies. Exchange rates are then surrogates for another environmental variable., relative price level, and move with inflation in the foreign economy rather than the foreign exchange market. There are several reasons to consider this possibility. First, internal inflation is often cited as a major factor contributing to changes in exchange rates. As a result, there is a priori basis for the hypothesis that exchange rates reflect the relative values of currencies in acquiring goods and services and changes therein due to inflation. Parkinson, for example, notes that "con- trol, or absence of control, over inflation is a factor in establishing an exchange rate." 2 -' Mueller contends: "There are many reasons why the for- eign exchange rate of a given currency may fall. Foremost are internal in- flationary pressures. " z ^ Similarly, Wells takes the following view: 25 Parkinson, p. 21. 2& Mueller, International Accounting, p. 173. 15 Devaluation and inflation are intimately connected. Exchange problems generally arise because devaluation takes place when the financial authorities of a country decide that the currency is overvalued , and that the country's balance of payments would bene- fit from a lower value of the ci rrency internationally. A cur- rency normally becomes overvalued because the supply of money has been increased without a corresponding increase in the amount of goods and services available for consumption — in other words, when inflation exists. A second reason exists to consider a relative value justification for the use of exchange rates in translation. A great deal of the theoretical reason- ing offered to support the use of particular exchange rates for certain items in traditional translation methods rests upon occurrence of internal inflation with material changes in exchange rates. The use of historical exchange rates in translating fixed assets in particular rests upon an "exchange rate-price level covariance assumption." It is presumed after devaluation of a foreign currency, for example, that internal prices will rise so that while the for- eign currency unit commands fewer dollars than before, the future flow of those units will be greater. Thus it is reasoned no real loss occurs and so, by use of historical rates, no loss is recognized. A final reason is that if exchange rates reasonably reflect relative pur- chasing power and their movements reasonably parody inflation, a seemingly sound conceptual basis is provided for their use in translation. Reasonable approxi- mation of relative value and reasonable adjustment for changes in value by 27 Michael T. Wells, "Devaluation and Inflation and Their Effect on Foreign Operations," Accountancy, (August, 1965), as reprinted in Kenneth B. 3erg, Gerhard G. Mueller and Lauren M. Walker, Readi ngs in International Accounting , (Boston: Houghcon-Mif f len, 1969), p. 262. A similar view is expressed by Shulman, i.e., fundamental disequilibrium occurs when high inflation affects international competitiveness to the point of structural deterioration in a country's balance of payments, R. B. Shulman, "Are Foreign Exchange Risks Measureable," Columbia Journal of World Business, V, No. 3 (May- June, 1970), p. 56, 16 exchange rates is all that should be expected of exchange rates. The alterna- tives are direct measurement versus surrogate measurement. An attempt at direct estimation of currency value is certain to involve difficulty and costs and be itself somewhat imprecise, In contrast, exchange rates are readily available for use at nominal cost. Upon investigation of exchange rates s depending upon the approach taken* we would expect certain conditions to hold in general for exchange rate behav- ior. Several criteria for assessing the appropriateness of using exchange rates in translation under an indirect relevance criterion suggest themselves. First, exchange rates should tend toward being equilibrium rates. An exchange rate could be deemed an equilibrium rate if it tended toward creating a zero balance of payments position; i.e., that rate which would tend to eliminate an existing payments deficit or surplus. A second type of equilibrium rate would be a "clearing" rate in the sense of tending toward a balancing off of international dealings at points in time and one which would not tend to change an existing payments position. Conceptually the two interpretations are the same in that given continuous existence of the latter the former could never exist . How- ever, large deficits do occur so the first type of equilibrium rate may be the best (in the sense of reflection of relative currency value) we can expect. Second, exchange rates should tend to move toward equilibrium on a timely basis. Material overvaluation or undervaluation of currencies should not persist for extended periods of time. This is particularly important. Timely recognition in the accounts of the effects of environmental variables is clear- ly desirable in order that action can be taken to avoid those which are dysfunc- tional. Also, erradic recognition of changing values frustrates single period and multiple period interpretation of financial statements. 17 Third, since rates are derived from the international goods market, equil- ibrium rates must basically express relative cost-price relationships between internationally traded goods. Relative purchasing power must be what is es- sentially being portrayed by exchange rates at different points in time and this should not be continually obscured by other forces acting on exchange rates. Fourth, the goods traded internationally and therefore their relative costs and prices must be fairly representative of the relative costs and prices of the goods and services that any multinational firm may deal in or hold. If this condition does not hold, then the value expressed by exchange rates is not relevant at the firm level. Since our concern is with a wide range of firms and therefore a wide range of assets held, there must exist some rea- sonable correspondence between the behavior of exchange rates and the behav- ior of local prices in general. There must be correspondence between internal _g^eral purchasing power of currencies and their external purchasing power — general purchasing power because, as Zenoff and Zwick state: "The impact in- flation may have on an affiliate of a multinational firm depends on inflation's effect on the overall, business environment."-^ The preceding four criteria provide a useful framework for evaluating exchange rates in a step by step fashion. The hypothesis that exchange rates reflect relative currency value must derive from a multiple-step reasoning process. Exchange rates arise from the supply and demand for currencies. The supply and demand for currencies is related to a country's balance of pay- ments. A country's balance of payments arises from the import and export of 28 ''Zenoff and Zwick, p. 53. 18 goods and services. The level of imports and exports for a country is a. function of supply and demand for internationally traded goods and services (including capital) and that in turn lepends upon the cost-price structure in that country vis a_ vis other countries. Thus a reasonable relationship between internal prices and the prices of currencies is possible. The four criteria deal with both the links in the necessary train of reasoning as well as accounting considerations such as timely adjustment and relevance at the firm level. Evaluation of Indirect Relevance Achievement of the first two criteria advanced, (i.e., reasonable ten- dency toward equilibrium and reasonably timely movement toward equilibrium) , can be assessed by way of an examination of past exchange rate behavior and identification of environmental variables which enter into determining that behavior. We shall conduct this examination on two levels — fluctuations of rates about par or parity and changes in par or parity values. The last two criteria reduce to a proposition that exchange rates parody the effect of in- flation on currency values and therefore firm values. This proposition is assessed in the final section of this paper. Fluctuations About Parity Given a central parity and upper and lower bounds for fluctuations around parity, a basic determinant of the value of any currency at a point in time (the spot rata) is the supply and demand for the currency . Supply and demand, in turn, is generally related to the country's balance of payments, and move- ments in exchange rates n will normally reflect changes in a country^ balance of payments." 2 ' Since balance of payments is directly related to cost-price ^Alan R. Holmes and Francis H. Schott, The New York Foreign Exchange Market „ (New York: Federal Reserve Bank of New York, 1965), p. 31. 19 structure through supply and demand for imports and exports , it is plausible that movement in exchange rates could be reflecting, to a large extent, changes in the relative value of currencies. However, at the short-term fluctuation level it is highly unlikely that value will be precisely specified or remain unobscured by other forces acting on the market rate as it moves around par. Interrelationships The relationship between internationally traded goods s their prices, price levels in general and exchange rates is less than simple. The prices of traded goods are affected by many factors other than supply and demand and internal price levels. The same holds true for exchange rates. They too are not just influenced by the balance of payments position of countries. For example, the prices of traded goods will be affected by border taxes, tarriffs, goods prohibitions, differing tax rates and various other impediments to a free flow of goods, money and services. These factors and other factors such as interest rates in one country versus another will likewise affect the supply and demand for a particular currency. As these factors change so also will exchange rates change. This raises an ancillary point. Not only is relative value between currencies obscured because these factors enter into the determi- nation of exchange rates, but the possibility of reasonable separation, iden- tification and measurement of the effect of changing values indirectly through use of market exchange rates becomes doubtful. While an account such as "ex- change gain or loss 1 ' may capture part of the effects caused by the factors above, other accounts such as tax expense, duties and cost of goods sold will be capturing additional or offsetting effects and not necessarily in the same accounting period. If a market exchange rate is responding to interest rate differentials, then an offsetting effect is implicit in any interest expense being recognized on foreign denominated debt. 20 Exchange Control s Exchange controls significantly interfere with supply and demand. The result is that value relationships which exchange rates under the influence of supply and demand for goods and therefore currencies might otherwise reflect become obscured. From the point of view of a particular government, devaluation or revaluation is merely one of several policy tools available for managing a country's international position* If a country is experiencing balance of pay- ments problems, changing the par value of its currency is one approach to solv- ing the problem. Another approach is to use fiscal or monetary policies to reduce aggregate demand. Interest rates, for example, may be exchanged to stimulate inflows of capital or to control inflation. Exchange controls, controls over currency exchange transactions by the government, constitute other "discretionary policy measures that can be employed to counter the free market forces affecting a country's balance of international payments." 30 Government control over exchange varies from little to complete both by countries and for single countries over a period of time. Nearly all countries have some remittance restrictions. For example, at December 31, 1971j companies in Greece were restr- cted to repatriation of invested equity at 10% per year and profits on equity at 12% per year. At that same time, Brazil not only restricted repatriation but also applied a penalty tax on remittances in excess of 12% per year. Multiple exchange rates exist in several countries providing preferential rates to exporters or importers or for certain goods over others. The point is that supply and demand for a currency and, therefore, its 30 Zanoff and Zwick, p. 41. 21 market rate of exchange is artificially controlled through exchange controls. Furthermore j, the impact of these controls is not stable* since they are changed frequently. The result is that neither the existing rate for a currency nor changes in that rate are reflections of supply and demand for the currency on numerous occasions. D ir ec_ t Mar ke t --M l^t erven ti on Exchange rates might still consistently reflect supply and demand for a currency, and so perhaps intrinsic value,, if supply and demand was not often overshadowed by another factor in the market. Relatively long-term imbalance can be perpetuated by government intervention in the foreign exchange market alone. As an exchange rate moves upward or downward from parity, a country may sell or buy its currency against dollars. In the case of the United States* the Federal Reserve Bank of New York enters the market to slow or halt move- ments within official limits. Such government intervention in the foreign ex- change market "is known to have taken place regularly since the IMF was founded, and particularly at times of considerable strain on those currencies which are world trading currencies."^- It should be noted that: Official activity is at least an ever present factor and at times may be the most important single element In the market. Implications From the foregoing observations it must be concluded that no meaning can safely be attached to any particular movement in an exchange rate about its es- tablished par for accounting valuation purposes. Change in the market value of a currency may have resulted from any number of factors unrelated to change " 1 J 1 Committee on International Accounting, p. 129. ■^Holmes and Schott, p. 14. 22 in the nature of the currency for purposes of claim on goods and services. We have discussed some of these factors. To those discussed we can add ran- dom, unfulfilled and self-fulfilling speculation, seasonal peaks in import- export activity s sporadic disturbances via singularly large international payments and surely other obscuring factors exist. Since fluctuations around parity cannot, in general, be associated with permanent, identifiable and measurable effects on firm values use of specific market rates in translation will often result in accounting recognition of tem- porary and reversing movements in rates which are of no discernable consequence to the firm. This can only introduce additional confusion into the interpreta- tion of financial statements that include foreign operations. This conclusion corresponds with that reached by Parkinson in the recent Canadian study where bookkeeping rates, generally seen as equivalent to official par values, were considered adequate for accounting translation purposes. Indeed, attempts to be precise by using specific market rates at year end, for example, were viewed by Parkinson as unconstruetive. -* C hanges i n Parity Parity Change as a Political Decision A change in parity results from a decision by government executives and, therefore, economic considerations are often outweighed by political considera- tions. The executive making the decision is a political realist balancing his (or his party's) political future against current economic need. Ke is free, to adjust the exchange rate by an amount that ^ -'Parkinson » p. 2. King agrees, maintaining that material distortion can result and suggesting that par values be used. Alfred M. King, "The Choice of a Foreign Exchange Rate," Management Account ing , XLIX, No. 8 (April, 1968). p. 13 23 will produce an equilibrium rate, or he can undervalue or over- value. Recent cases in support of all three types of decisions can be cited. ■*** The important point is that the establishment of a parity value may easily rest on non-economic factors, factors unrelated to or in conflict with setting a realistic value for a currency. Such factors would include the characteris- tics of the decision makers, the outlook of advisors and domestic political considerations . j:) Too Much. — Too Little There is ample evidence to show that parity changes will often be too great or too little in terms of establishing equilibrium rates. Long-term overvaluation or undervaluation of a currency can be expected to be common- place. The establishment and maintenance of a par value which undervalues a currency may be motivated by a desire to minimize the possible necessity of later devaluation with attendant inflationary effects. 3" Another reason may be to increase demand for export goods. In contrast, overvaluation may be maintained to retain the favorable position this gives in international trade. Devaluation, in particular, is often excessive as it is nearly impossi- ble to determine the precise effect on international payments which will re- sult. As a result, excessive devaluation tends to accentuate the speed and magnitude of retaliatory actions by other countries. 37 Zenoff and Zwick note another cause of excessive devaluation, that being a desire to avoid disturbing 34 ShuIman, p. 57. * 5 Zencff and Zwick, pp. 68-69. 3°Samue.l R„ Hepworth, Reporting For eign Oper ations, (Michigan Business Studies, Vol. 12, No. 5), (Ann Arbor: University of Michigan, 1956), p. 105. 37 Ibid., p. 133. 24 investor confidence in the country. When economics make devaluation inevitable, the size of the adjustment may be founded on the expectation "that one big de- valuation now will preclude having t"; make a series of changes over the ensuing year or two."^" Also* an overly large devaluation may be required to convince speculators that no further devaluation will occur in the immediate future. 39 In still other cases there may exist an overriding intent to maintain stability in an exchange rate whether or not warranted. Mexico is a ready example. ° Reference to specific cases of par value changes noticeably imprecise, and perhaps intentionally so, can be made. Other cases can be cited where, intuitively, there is no reason to believe realistic currency value adjustment was even involved. For example,. the mark was revalued in 1969 by only 4% and the continuing trade surplus after revaluation demonstrated that the adjustment was clearly insufficient to correct the existing disequilibrium. A more re- cent example can be found in the first revaluation of the yen.**-*- Another ex- ample is provided by England's devaluation in 1967 where 22 countries closely tied to Great Britain economically also devalued, 17 doing so by the exact same percentage as that of the original adjustment .^ Bach has observed the tendency lo postpone a parity rate change "until financial and political pressures made it imperative."* 3 In particular, he 38 Zenoff and Zvick, p. 87. -"Don Schilling, "Devaluation Risk and Forward Exchange Theory," American Econom ic Review , LX t No. 4 (September, 1970), p. 722.

Bach, "Problems of the International Monetary System and Proposals for Reform— 1944-1970, " Federal Reserve Bank of St. Louis Monthly Re- view, LIV, No. 5 (May, 1972), p. 31. 25 refers to the observable sluggishness in changing par values from 1958 to the devaluation of the pound in 1967 and the fairly extensive use of tariffs, quotas and other controls as alterna ivas to devaluation during the 1960s. Similarly, Mandich asserts that, there is generally "a long prelude of deteriora- tion covering several years" before devaluation occurs, especially with regard to more developed nations with substantial reserves to draw on to de- fend an existing par value. ^ Indeed, for developed countries generally, de- valuation has become a policy measure of last resort." 4 -* Less developed coun- tries will similarly avoid devaluation in order to not discourage foreign investment. For example, Zenoff and Zwick observe that during 1965-1967 many viewed India's devaluation of the rupee as resulting from intense pressure by the United States on an Indian government that was not inclined to devalue. " Shulman cites the British situation in 1964 where the Prime Minister was faced with immediate devaluation or postponing such devaluation and chose the lat- ter. *' Instead of devaluing Britain instituted a 15% surcharge on imports in October, 1964 which was reduced to 10% in 1965 and then lifted in November of 1966. Britain was eventually forced to devalue in November, 1967. Implicat ions It appears that any expectation that par values will tend toward being reasonable equilibrium rates and be adjusted on a reasonably timely basis is unfounded. As a result, placing reliance on par values instead of market rates as surrogate measures of relative value will still not lead to satisfactory 44 Mandich, p. 29. '^Schilling, p. 722. 46 Zenoff and Zwick, p. 85. 47 Shulman , p. 58. 26 accounting results. Since these par values will often entail considerable currency overvaluation or undervaluation over extended periods of time, their use in translation will result in persistent overvaluation or undervaluation of the net assets of foreign-based firms. If and when devaluation or revaluation occurs any one of a number of fac- tors , economic, political and so on, may underlie the change. A complex in- teraction process involving numerous variables in any number of possible com- binations is involved. Directly linking any change in an exchange rate, a market rate or a parity value, to identifiable and measureable individual effects on firm accounting values at the time of such an event seems an im- possible task. Excha nge Rates and Price Levels Our third criterion briefly reiterated was if exchange rates reasonably approximated equilibrium rates, such rates would also need to reflect fairly clearly cost-price relationships between internationally traded goods. The fourth criterion was these goods would, in turn, have to be somewhat repre- sentative of goods generally. As noted, these criteria reduce essentially to a single, directly assessable proposition: exchange rates are reasonable sur- rogates for the relative purchasing power value of currencies and their move- ments reasonably parody relative inflation, If this proposition is true, then the economic impact of an important environmental variable would be associated with accounting adjustments for changes in exchange rates and a sound basis for cross-national valuation would be provided. An account such as "exchange gain or loss" would then be related to indirect measurement of a relevant environmental variable — inflation. Any gain or loss recognized would be definable in real economic terms. Unfortunately, 27 such a proposition is patently false. Authoritative Support Authoritative support for the proposition that a reasonable relationship exists between exchange races and price levels is for ail practical purposes non-existent* Instead* the conclusion generally reached by those who have addressed the question is that such a relationship does not hold with any regularity that would make exchange rates useful from an accounting valua- tion standpoint. Some maintain that the pure form of the relationship prob- ably could never exist. Paul Rosenfieid expresses such reservation: "Ideally, under complete freedom of trade and of the deter- mination of exchange rates, the exchange rate would reflect the relative purchasing power of the two currencies. . .Actually, the ideal situation seldom, if ever exists. ,r The ideal situation in fact may never exist if the goods and services exchanged between the two countries are not representative of the goods and ser- vices in general purchased within each country. 48 David » viewing the problem from an economics perspective of measuring real per capita income differences, maintains that sufficient reason exists to expect marked differences between the relative prices of traded and non- traded commodities. Whether or not a perfect relationship between exchange rates and price levels can exist is really not that important. From an accounting standpoint all that is sought is reasonable corresponds^. The consensus opinion is that such correspon- dence does not generally exist. For example, Hepworth saw "no reason to believe ^"Paul Rosenfieid, ''"General Price-Lave!

"^^ Business Wee k maintains that official rates "are frequently a poor measure of the actual purchasing power of a country's currency" and Zenoff and Zwick assert that empirical evidence tends to support this contention. •*- Along the same lines, a committee examinirg the Argentina exchange rate situation found : ...foreign currencies have their own variations in purchasing power and* as the reality of our own country ? s situation teaches us, the variations in the value of foreign currencies have a direction and intensity different from those manifested by internal prices. Dt - In general, the opinion of those who have examined closely the question of whether exchange rates mirror price levels seems captured in the following: There is often considerable difference between these rates so stated by a government and the price structure within a country, that is, the changes in local price structure of a country are not neces- sarily expressed sympathetically and automatically in the current exchange rates . ^3 Finally, when a relationship does appear to exist, the sequence in which events occur may vary. Where normally inflation comes first and then currency depre- ciation, in ether situation the opposite occurs where devaluation comes first and inflation follows.-'' 4 50 Hepworth, p. 139- 5"!

Such an observation forces rejection of this proposition. Any number of specific contrary cases can be cited. Consideration of the countries which have recently revalued relative to the dollar will show that several have consistently experienced greater rates of inflation than has the U.S.; Germany, France and Great Britain are examples. As Zenoff and Zwick have pointed out: If this assumption is correct that devaluation and revaluation move together there should have been, for example, a steady de- valuation of. European currencies against the dollar during the last twenty years since inflation in Europe has generally been higher than in the United States. Not only has the anticipated devaluation not occurred, but the Deutsch mark and the Cilder have been revalued upward in relation to the dollar. Nor is the assumption any more accurate in the case of countries that have experienced much higher rates of inflation than has Europe. Bra- zil is a case in point. During the recent past the cruzeiro has remained at 2,200 to the dollar during a twelve-month period when internal prices have risen more than 40 per cent per annum. -> Argentina provides a case similar to that cited by Zenoff and Zwick for Brazil. If the exchange rate had moved tandem with the relative prices struc- tures of the U.S. and Argentina between 1953 and 1960 the exchange rate, in 1960 would have been about 35 pesos to the dollar; in point of fact the offi- cial rate in I960 was 82.7 pesos to the dollar. -> 6 In the case of Peru, Wells has observed that where, internal inflation had reached 20% per year in 1965, 55 Zenoff and Zwick, p, 498. -^Sapienza, p. 29. 30 57 during the five previous years no devaluation had occurred. Parkinson has made similar observations regarding correspondence between exchange rates and inflation. First ha has observed that changes in one currency relative to another currency do not follow the same pattern as do changes in either of the currencies relative to the U,S, doilar s the Cana- dian dollar or other currencies. Second, he notes that: Prices appear to increase in Canada when there is "full em- ployment" and when there is much unemployment; prices increase when the Canadian dollar goes up in value and when it goes down. A review of price changes following upward and downward changes in the external value of the Canadian dollar (in terms of the U.S. dollar) fails to indicate any direct relationship between the two phenomenon . J ° Parkinson cites the specific example of the decline of the U.S. dollar by approximately 7% relative to the Canadian dollar in June, 1970. He maintains it was reasonably. clear that the change was not a direct consequence of infla- tion in the U.S. or inflation in the U.S. relative to Canada. ^ One can return to Germany for an even more recent example. During the first six months of 1971 the consumer price index in Germany rose from 121.1 to 126.1, the same period in which Germany revalued. Additional single cases of a lack of correspondence between relative costs and prices and exchange rates could be cited. This is not necessary, however, since several broad empirical studies of the relationship of purchasing power to exchange rates are available and all show similar results. One such study was conducted by Milton Gilbert and Associates.^ The NAA refers to this study in the following: 57 "* Wells, p. 271a 58 ' Parkinson a pp. 86-87. Ibid^, p. 73. uw Milton Gilbert and Associates, Comparative National Products and Price Levels, (Paris: Organization for European Economic Cooperation, 1958). 31 . . . , common experience Indicates that relative price levels in the United States and other countries do not correspond closely to rates of exchange between the currencies. A study of compara- tive national price levels in the United States and eight Euro- pean countries supplies statistical evidence to support this ob- servation. For example, this study shows that in 1955 an expen- diture of $1.20 was required to buy in the United States what could be purchased in West Germany for $1.00 converted to marks at the current rate of exchange. If consideration was given to differing expenditure patterns in the two countries, $1.66 was required to purchase in the U.S. what $1.00 converted to marks would buy in West Germany. *~ Table 1 shows for the yeans 1950, 1955 and 1960 the ratio of the pur- chasing power of selected currencies to their official dollar exchange rates. Several aspects of the table are worth noting. First, the countries listed are particularly relevant. Multinational activity therein easily account for the bulk of foreign operations. Also, the discrepancies between external value and internal value are both material and unstable over time. Though, on the whole, differences have tended to consistently diminish over time, specific contrary cases are present; i.e., France and Belgium. Finally, the patterns of change over time vary dramatically from country to country so that the bias of exchange rates is not systematic. In other words, accounting valuations based en exchange rates cannot even be expected to involve com- parable degrees of overvaluation or undervaluation.

With regard to the first, that exchange rates might be directly relevant as commodity prices, we found this approach requires a concept of the firm which is unrealistic and theoretically unsatisfactory. With respect to the second concept (i.e., indirect relevance), we. found that the available evidence does not suggest that exchange rates are reasonable surrogates for measures of relative currency value. Hence, we conclude there is no readily apparent basis for using exchange rates in lieu of other data, except that the nature of that other data and the theoretical structure to underlie its use remains unspecified. The specification of an alternative theory of translation and an alternative to exchange rates will be the subject of a future paper.
