IANA-CHAMPAIGN Theft, BMtilation) and underlining nary attioff add rn'ay result To renfw ia^T|ltto|c^* D = 10 as described in Appendix A. Federal government purchases . For both defense and non-defense purchases, the following assumptions apply: new construction inputs are based on a good data source, so assign 6 = .05; maintenance and repair construction is more subject to classification errors, so 6 = .10. All entries between $10 million and $50 million are assigned 6 = . 30 unless otherwise specified below. Purchases less than or equal to $10 million are assigned D = 2 -*■ 10 as discussed in Appendix A. **Based primarily on interviews with Jerry Schluter, U.S. Department of Agriculture. Based primarily on interviews with Roy Seaton, Bureau of Economic Analysis, Defense purchases are generally better known, due to more complete source data. Inputs from manufacturing sectors are assigned 6 = .10 if they exceed $50 million. Transportation inputs vere derived from outdated formulae that applied poorly to the Southeast Asia situation in 196T and are assigned 6 = .50. Other non-manufacturing inputs were assigned 6 = .10 if they were above the $50 million threshold. Non-defense purchases of inputs from non-manufacturing sectors were less well known, and were assigned D = 3 if they exceeded one percent of total inputs and D=3->10 if they were smaller. Manufacturing inputs below the $50 million threshold were treated the same. Transportation inputs were assigned 6 = .30. State and local government purchases . For health, welfare, education, and sanitation purchases, new construction and real estate inputs are as- signed 6 = .05 since they are obtained from census sources. Together with wages, these inputs account for nearly 75% of all inputs. Other inputs are assigned 6 = .25 if they exceed 1% of total inputs, and D = 1.5 ^ 10 as per Appendix A if they are equal to or smaller than 1%. For public safety purchases, new construction and real estate are assigned <5 = .05. Maintenance construction is known poorly; D = 1.5. Manufactured inputs greater than $2 million are assigned D = 1.5, and smaller inputs D = 1.5 "► 10. Non-manufactured inputs are assigned D = 1. 5 for those greater than $10 million, and D = 1.5 ■+ 10 for the smaller ones. Other state and local government purchases are also assigned 5 = .05 for new construction and real estate, but also 6 = . 05 for maintenance construction since it is primarily highway maintenance which is a Census Based primarily on interviews with John We alt y, Bureau of Economic Analysis -9- number. Manufactured inputs greater than $5 million are assigned D = 1.5, and smaller figures D = 1.5 -> 10 as per Appendix A. Non-manufactured inputs greater than $50 million are assigned D = 2 and D = 2 -> 10 for smaller inputs. Imports and exports . Trade data for commodities (BEA sectors 1.00 - 64.00) are obtained from Census sources and are assigned 6 = .05. Trans- portation and wholesale and retail trade data, including margins, were assigned 6 = .25. Data on other items (services, etc.) involved in international trade were assigned D = 2, since they were obtained from balance of pay- ments sample data. Small entries at the 368-sector level of detail, repre- senting less than 1% of gross imports or exports were assigned D = 2 -> 10 as per Appendix A. Inventory change . These figures are in general the least accurate of all final demand entries, and were assigned 6 = .20 for manufactured goods and 6 = .Uo elsewhere. "All other" direct allocations . Within the scope of this study it was impossible to identify those responsible for most entries in the input- output tables. Having taken care of most entries through interviews des- cribed above, the remainder were handled as a group. The algorithm was designed to assign very tight tolerances to any transaction comprising a high percentage of total outputs or inputs, and to any sector's output which "by definition" had to be assigned to a particular cell. For example, the algorithm had to assign a very tight tolerance to sales from new resi- dential construction to gross private capital formation, so it would be compatible with the tolerance assigned to that sector's gross domestic out- put. There are numerous other instances where census data might identify Based primarily on interviews with Robert Mangen, Bureau of Economic Analysis, -10- sales of butter to food processors or bakers , and the remainder is attri- buted to personal consumption expenditures. On the other hand, very small- magnitude transactions were assigned high uncertainty for the reasons dis- cussed earlier. The algorithm defined two fractions for each direct allocation: an input fraction, by normalizing with respect to the gross domestic output of the consuming sector; and an output fraction, by normalizing with respect to the gross domestic output of the producing sector. The algorithm proceeds with these tests in the following order, and assigning 6 or D when the first condition is satisfied: if both fractions exceed .95 then 5 = .01, if only one exceeds .95 then 6 = .02; if both exceed .80, 6 = .05, if only one exceeds .80, 6 = .10; if either fraction ex- ceeds .05, then 6 = .20; if either exceeds .01, then D = 1.5. If both are smaller than .01 it assigns D = 2 -+ 10 as per Appendix A. Energy Sector Rows . Estimates of relative uncertainty were made by Knecht (1975). Appendix A. 3 gives these estimates, interpreted consistent with the other estimates in this document. These do not apply directly to the dollar transaction data published by BEA; for that information the pre- ceding subsections apply. These estimates are for transactions measured in physical units, assembled from primary sources by Smith and Simpson (197^). Since the University of Illinois model relies on this physical data rather than the dollar transaction, all analyses based or. the uncertainty esti- mates presented here will employ the modified model. For this reason the additional information is included in Appendix A. 3 for completeness. -11- 3. 2 Gross domestic output . These figures are the best known because they are from the Census or other equally reliable sources (e.g., IRS) and are assigned 6 = .01. The largest errors here probably stem from classification problems and possible confusion between company and establishment-based data. 3. 3 Transfers . If both the row and column sectors were manufacturing sectors, the source of this data was the Census Bureau, but the accuracy was less than that of direct allocations; assign 6 = .20. All other transfers were assigned upper and lower bounds in the same manner as the corresponding cell in the direct allocations matrix. 3.J+ Margins Transportation margins, by product type and mode, are obtained as totals and then prorated proportional to producers' prices across all pur- chasers of that commodity. Then margins in each input are summed for each purchaser and added to the directly allocated inputs. For all transport modes, 6 = .25 was assigned to the margins. Wholesale and retail trade margins may be expected to be more variable, and are some- times computed as percentage markups over the already estimated trans- port margins. Therefore they are assigned 3 EARING CROPS 00 00 1 1 11 00 15 FOR./ GRNHSE/ NURS. 11 00 OP OS 11 16 FORESTRY ?
