The Bureau of Eonomic Analysis (BEA) has completed most of its 11th comprehensive revision of the national income and product accounts (NIPA's) with the release of revised NIPA estimates for 192958 and of estimates of fixed assets and consumer durable goods for 1998 (new) and for 192597 (revised). These estimates incorporate the definitional, statistical, and presentational improvements that were introduced last October into the revised estimates beginning with 1959./1/ In addition, BEA has released revised estimates beginning with 1959 that incorporate corrections and a previously announced improvement in methodology. The article "Fixed Assets and Consumer Durable Goods: Revised Estimates for 192598" in this issue presents the estimates of fixed assets and consumer durable goods; this article describes the revised NIPA estimates.
A list of the data series released in October 1999 and published in the December 1999 issue of the SURVEY OF CURRENT BUSINESS that have been corrected or revised is shown on page 32. NIPA tables that present annual estimates for 199599 and quarterly estimates for 1997:I1999:IV begin on page 36./2/ Tables that present estimates of gross domestic product (GDP) and other major NIPA series for 192999 begin on page 126. For further information on the availability of the revised estimates, see the box on page 12.
Tables 13 of this article show annual levels, percent changes, and revisions to percent changes for current-dollar GDP, for real GDP, and for the chain-type price indexes for 192998.
Revisions to change.For 192958, the average annual growth rate of real GDP was unrevised at 3.4 percent. The largest revision to an annual growth rate of real GDP was +0.5 percentage point for 1947, reflecting a revision to Federal Government consumption expenditures and gross investment, which, in turn, reflected a revision to the change in inventories of the Commodity Credit Corporation. Other revisions to annual growth rates of real GDP were 0.4 percentage point or less in absolute value and primarily reflected revisions to the change in private inventories and to Federal Government consumption and investment. The revisions to the change in private inventories reflected the new methodology for construction inventories that eliminated the double-count of construction work-in-progress and unsold finished structures./3/ For 193947, revisions to real Federal nondefense consumption and investment reflected the use of additional detailed information on prices of Commodity Credit Corporation inventory changes.
Beginning with 1959, the revisions to real GDP reflected a correction to real "services furnished without payment by financial intermediaries." This correction affected real GDP and prices, but it did not affect current-dollar GDP. The average annual growth rate of real GDP over 195998 was unrevised at 3.4 percent. For specific years, the revisions were more notable. The largest revision to the annual growth rate of GDP was +0.4 percentage point for 1976; the growth rate for 1993 was revised up 0.3 percentage point. The growth rates for 1974, 1991, 1992, and 1997 were each revised down 0.3 percentage point. The components of real GDP and GDP prices that were revised as a result of this correction were personal consumption expenditures (PCE), exports of services, Federal Government nondefense consumption expenditures, and State and local government consumption expenditures.
Revisions to the chain-type price indexes reflected many of the same changes in methodology that affected estimates of real GDP. For 192958, the average annual growth rate of the gross domestic purchases price index was unrevised at 1.9 percent; revisions to annual growth rates ranged from -0.4 percentage point for 1940 to +0.2 percentage point for 1942. Beginning with 1959, the growth rates of prices were revised in the opposite direction of the revisions to real GDP growth rates that resulted from the correction to real "services furnished without payment by financial intermediaries"; current-dollar GDP and its components were not revised. For 195998, the average annual growth rate of gross domestic purchases prices was unrevised at 4.1 percent; revisions to annual growth rates ranged from -0.3 percentage point for 1976 to +0.4 percentage point for 1974.
For 197798, the growth rates of real gross product of nonfinancial corporate business and of its price index were revised, reflecting a previously announced improvement in methodology in which a new industry-based price index is used for deflation./4/ Previously, the implicit price deflator for goods and structures in GDP was used to deflate this aggregate. The new index better reflects the changing industrial composition of this sector, in which the production of services has become increasingly important, and it provides better measures of productivity, costs, and profits per unit of gross product. For 197798, the average annual growth rate of real gross product of nonfinancial corporate business was revised down from 4.1 percent to 3.7 percent; the downward revision reflects the tendency for prices of services, which were not included in the previous deflator, to increase faster than prices of goods.
Revisions to level.Revisions to the levels of current-dollar GDP for 192958 were generally small and mainly reflected methodological improvements. The revisions ranged from -0.1 percent for 1946 to +0.4 percent for 1932 and mostly reflected revisions to change in private inventories, to government consumption and investment, and to PCE. The revisions to government consumption and investment were mostly to State and local government consumption of fixed capital (CFC) and reflected the use of a shorter service life for depreciating highways and streets./5/ For 195998, current-dollar GDP and its components were unrevised.
Revisions to national income ranged from -0.6 percent for 1958 to +0.6 percent for 1933. For 192946, the revisions primarily reflected revisions to the capital consumption adjustment (CCAdj) because of corrections to pre1925 data on fixed assets and prices. For 194758, downward revisions to national income reflected a change in the methodology for estimating the rental income from nonfarm nonresidential properties, which was carried back to 1947./6/ For 195998, small revisions to national income reflected revisions to the CCAdj, which in turn resulted from a correction to CFC. This correction also affected current-dollar and real net domestic product, but it did not affect GDP. National income was revised up by small amounts, reflecting upward revisions to profits from current production that, in turn, reflected upward revisions to the corporate CCAdj. For 1998, national income was revised up $2.4 billion.
Within GDP and gross domestic income, the revisions to the CCAdj were largely offset by revisions to CFC. Thus, revisions to the statistical discrepancythe difference between GDP (the "product-side" measure of output) and gross domestic income (the "income-side" measure of output)mainly reflected the revisions to the change in private inventories and to rental income of persons. For 194758, the statistical discrepancy was revised up, reflecting downward revisions to gross domestic income that, in turn, reflected downward revisions to rental income.
For 195998, gross product of corporate business was revised down, reflecting a correction to the allocation of indirect business tax and nontax liabilities by legal form of organization and by industry./7/ This correction did not affect GDP, gross domestic income, or national income. The revisions to gross product of corporate business mostly reflected revisions to gross product of nonfinancial corporate business. For 195998, current-dollar gross product of nonfinancial corporate business was revised down substantially for all years; the revisions ranged from -3.1 percent for 1961 to -1.4 percent for 1988.
For 192958, revisions to personal income ranged from -0.2 percent for 1955 to +0.4 percent for 1943. These revisions mostly reflected the definitional change in the treatment of government employee retirement plans and the methodological change to rental income./8/ Revisions to disposable personal income (DPI) ranged from +0.2 percent for 1955 to +1.1 percent for 1938 and reflected the redefinition of estate and gift taxes as capital transfers and the definitional and methodological changes that affected personal income./9/ Revisions to the personal saving rate ranged from +0.3 percentage point for 1955 to +1.1 percentage point for 1938. For 195998, personal income, current-dollar DPI, and personal outlays were unrevised, but real DPI and real PCE were affected by the correction to real "services furnished without payment by financial intermediaries."
