RELIABILITY OF THE QUARTERLY NATIONAL INCOME AND PRODUCT ACCOUNTS OF THE UNITED STATES, 1947–1971*

The reliability of the quarterly national income and product (NIP) accounts of the United States is examined from several standpoints. First, possible sources of error in the quarterly NIP accounts are explored, the most important being the lack of appropriate data, seasonal adjustment errors, sampling errors and biases, and the nature of the U.S. statistical system. Next, four ways of assessing the reliability of the accounts are considered. The most weight is given to measures of revisions in early estimates of the quarterly NIP aggregates. Results of previous studies of revisions are reviewed, and a summary of a major study of revisions for the period 1947–71 is given. The other ways of assessing reliability which are examined are the effect of errors on economic policy making, analysis of the statistical discrepancy, and expert judgment on sources and methodology. The degree of accuracy is judged to be generally sufficient for the policy decisions for which the NIP estimates are used. The early estimates of a quarter's change in GNP almost always distinguish whether the ultimate estimate will be large or small and will usually distinguish whether the ultimate estimate will be larger or smaller than the preceding quarter. While the accuracy of the estimates has generally been sufficient, the accuracy for 1965 was judged insufficient by policymakers. There is some evidence that errors have been reduced over time.     

THE DEVELOPMENT OF NATIONAL ACCOUNTS IN ARGENTINA*

The history of national accounting in Argentina is presented in brief. The use of the production method as a basis for GDP estimates is explained and sources and methods of deriving the estimates for different sectors are commented on in some detail. Next the reliability of the estimates is examined for sectoral product, national income by factor shares and the components of final expenditure in terms of the comparison of two different estimates for the period 1950–1963. The degree of accuracy is judged to be generally sufficient, but the importance of economic censuses in the process of estimation is stressed. The importance of detailed studies on several different aspects of the economic structure (input-output, personal and family income by size and regional accounts) is also stressed as a basis for improving the reliability of estimates.     

ACCRUED CAPITAL GAINS, PERSONAL INCOME AND SAVING IN THE UNITED STATES, 1948–1964

Capital gains are an important source of personal income in the United States but they are not included in the national accounts or the official estimate of personal income and saving. Individuals report their realized gains for tax purposes but the economic theorist would include both realized and accrued gains in income. National income theorists continue to debate whether capital gains should be included in income but, because of the many conceptual and statistical problems involved in estimating capital gains, no satisfactory estimates have been developed. Consequently, the debate has stayed mainly at the theoretical level. This paper deals with the methodology of estimating accrued capital gains. A simple analytical model is developed to estimate capital gains from data on market value and net acquisitions of an asset but the model can be adapted to incorporate asset prices directly. It is shown that the methods used for estimating accrued gains in the past are special cases of the model proposed in the paper. The model is then used for estimating gains accruing to individuals in the United States on their holdings of corporate stock, real estate and livestock during 1948–1964.
During this period accrued gains have amounted to roughly five times the realized gains reported for tax purposes; corporate stock and real estate are the most important sources of capital gains and corporate stock accounts for almost two-thirds of all accrued gains. The paper goes on to examine the implications of these estimates for the existing series on personal income and saving in the United States. The inclusion of accrued gains would increase the variance in the official estimates but personal saving is affected more than personal income. The paper concludes with an evaluation of these results and some suggestions for further research.     

THE ACCOUNTING TREATMENT OF HUMAN INVESTMENT AND CAPITAL

Defining investment as outlays that increase income- and output-producing capacity, the author presents estimates of human investment in the United States 1929–69, comprising rearing costs, education, training, health, safety and mobility outlays. He develops an economic accounting framework to accommodate human investments and research and development in national and sector capital accounts, with appropriate adjustments to the current accounts to provide consistency. The associated balance sheets and wealth statements are also developed.
The wealth and corresponding income estimates are used to compute rates of return on human, non-human, and total capital. In the business economy the average net rate of return on total capital was 10.6 percent in 1969, compared with 10.0 percent in 1929. The average and marginal rates of return on human capital were generally somewhat higher than on non-human capital throughout the period.     

THE UNITED NATIONS SYSTEM OF NATIONAL ACCOUNTS IN THE MIDDLE EAST

After an introduction setting out the general state of work on the national accounts in the Middle East the author considers the principal uses of national accounts statistics in less developed countries. The first group of uses discussed is in connexion with the measurement of growth and the making of international comparisons. The author is of the opinion that in many cases the primary statistical series are so weak that the fact they they are combined together into a series called national income or gross domestic product lends to them a significance which they do not really possess. The real problem is to improve the quality of the primary series. A second use of national accounts statistics is in connexion with fiscal and budgetary policy. In the statistically advanced countries this is one of the most important uses but in the less developed countries budgetary policy has not yet reached a level of sophistication which would call for the use of national accounts data. Moreover, the time factor involved in assembling accurate national accounts estimates militates against their effective use for short term forecasting. The author considers that the most important use for national accounts statistics is to provide a framework for development planning. The United Nations system is not altogether appropriate for this purpose. It grew up primarily as a system for recording income flows but in development planning one is concerned equally with commodity flows with a great deal of attention being focussed upon intermediate products. The proposals of the working group of African Statisticians for an adaptation of the S.N.A. to African countries represents a most important advance in this respect. In the final section of the paper the author advocates a broader definition of capital formation to include developmental expenditure which is not properly defined as fixed capital formation. Education expenditure is cited as an example. It is suggested that in the national accounts it would be desirable to operate with gross concepts. However, the growth of the capital stock is obviously important in less developed countries and it is suggested that statistical techniques be devised to measure it directly wherever possible. Finally, attention is drawn to the ambiguities and weaknesses in the concept of residence as used at present in the S.N.A.     

EXPANDING IMPUTED VALUES IN THE NATIONAL INCOME AND PRODUCT ACCOUNTS*

After defining economic activity the author lists the chief types of non–market economic activities for which he has prepared estimates for the United States 1929–1973, and briefly describes his methodology and data sources. Some major findings are: (1) As of 1973 GNP adjusted to include the additional imputations was 63.5 percent larger than the official estimate. (2) At least since 1929 imputed values have grown faster than official GNP, especially when both are measured in terms of real factor costs. (3) The personal sector comprises a far larger portion of the national economy-almost one-third—when account is taken of imputed labor and property compensation, and its relative importance has grown. (4) Gross government product is more than 60 percent higher when the imputed rental value of public property is added to the compensation of general government employees. (5) Reflecting the relative growth of non-business wealth, imputed property income has risen much faster than monetized property income. This has mitigated the decline in the property share of expanded gross national income compared with its share in the official estimates.     

AN EXAMINATION OF THE FEASIBILITY OF USING MONETARY DATA FOR NATIONAL INCOME ESTIMATES

In a number of underdeveloped countries today, adequate statistics for estimating national output by traditional national accounting methods are unavailable or unreliable. However, many of these same countries do publish data on monetary variables at an early stage in their development. These data can now be used to estimate national income.
In this study the money supply was defined to include all currency in circulation, private deposits subject to check at all banks and postal systems, all government deposits, and unused overdrafts less float. The national accounts data were taken from United Nations sources and data supplied by various foreign statistical offices. To make the accounts more comparable in terms of coverage and to limit reported income to the monetized sector of the economy, non-monetary imputations were deleted.
The monetary and national accounts data were combined in a multiple, stepwise regression. National income was used as the dependent variable and money supply and other data were used as the independent variables. The final estimating equations explained about 96 per cent of the variation in income between countries. Other tests were conducted using the currency ratio, transactions velocity, population, and per capita consumption. However, these variables did not augment the explanatory power of the regression equations.
When the equations were used to estimate national income for twenty-two under-developed countries, the derived estimates showed a high degree of concordance with reported income where it existed for comparative purposes. The results indicate that monetary data can be used to estimate national income for underdeveloped countries with a relatively high degree of accuracy, between countries, and from year to year within a country.     

REPORT OF A CONFERENCE ON THE PROPOSALS FOR REVISION OF THE UNITED NATIONS SYSTEM OF NATIONAL ACCOUNTS, HELD BY THE CONFERENCE ON RESEARCH IN INCOME AND WEALTH

This report summarizes the proceedings of a series of meetings called by the Conference on Research in Income and Wealth of the National Bureau of Economic Research in June of 1966. The major conclusions of the conference, as transmitted to the Statistical Office of the United Nations, were as follows: (1) The aim of integrating the various parts of the system of national accounts, including input-output and financial transactions, is to be welcomed. (2) The more recently developed parts of the system need considerably more work to reach the same level of clarity and usefulness which the national income and product accounts have acquired. (3) Some simplification of the proposed basic system should be considered, involving the identification of a minimum of information that should and could be provided by all countries. (4) In line with the conference's overriding interest in national accounts as an instrument for economic analysis and a means of more informed policy formation, the proposed system needs considerable strengthening in the field of income distribution.     

EXPERIENCES AND PROBLEMS OF THE CIS COUNTRIES IN TRANSITION FROM THE MPS TO THE SNA

This paper reviews the transition of national accounts in the Commonwealth of Independent States (CIS) countries from the Material Product System (MPS) to the United Nations System of National Accounts (SNA) and discusses the major problems that still need to be solved in order to improve the quality of their national accounts. It argues that the MPS practice tended to exaggerate growth not because of different concepts, but because of methodological problems such as inadequate deflation due to poor price data and incomplete coverage of the non-observed economy as well as overpricing of new or modified products and institutional flaws that motivated data fabrication by enterprises. However, the heritages of the problems under the MPS, together with the emerging new types of institutional units, new sources of income and market-driven new services, have made the transition difficult.     

THE DISTRIBUTION OF PUBLIC EXPENDITURES AND TAXES AMONG HOUSEHOLDS IN THE UNITED KINGDOM*

This paper presents an analysis of the distributive impact of public expenditures and taxes in the United Kingdom. The analysis uses household level microdata from the 1971 Family Expenditure Survey, with tax and expenditure aggregates drawn from the national accounts. The analysis is the first to allocate all taxes and public expenditures for the United Kingdom, and the results are compared to those from the more restricted analyses carried out by the U.K. Central Statistical Office. Results are presented for individual taxes and benefits as well as for overall net benefits and they describe distributional effects with respect to income class, household size, number of earners and housing tenure. A final section of the paper compares the results to those from a similar analysis for the United States which were reported in the previous issue of this review.     

NEW INSIGHTS INTO THE STRUCTURE OF THE WORLD ECONOMY*

The United Nations' newly completed study of purchasing power parities covering 34 countries varied in region, income level, and form of economic organization shows the systematic differences between the usual view of the structure of the world economy arising out of international comparisons based upon foreign exchange rate conversions and the structure one sees when actual prices are available. The real per capita GDP of developing countries is understated relative to developed countries when exchange rates are used in converting countries' national income accounts to a common currency, with the degree of understatement for any two countries being inversely related to the per capita income difference between them. The reason for this is that relative prices in the non-traded goods sector are lower relative to traded goods prices in low income countries. The systematic pattern observed in the 1975 data of the 34 countries has been extrapolated over time and space to get estimates of GDP for other years and countries. In the absence of detailed price data, the real shares of final expenditures devoted to particular components of the total can only be estimated as the proportion of own currency total expenditure devoted to the components. The observed differences in the pattern of prices of poor countries relative to rich for different components makes this clearly wrong for international comparisons, and in systematic ways. For example, (i) the relative price of services compared with commodities in poor countries is lower than in rich; so the apparent tendency of the share of services to rise as a country's income rises disappears when real quantities are considered; similarly, (ii) the relative price of capital goods is greater in poor countries compared with rich ones, so the difference in investment ratios out of GDP between rich and poor countries is understated.     

THE MEASUREMENT OF U.S. REAL CAPITAL INPUT, 1929–1967

The purpose of this paper is to develop methods for the measurement of real capital input. These methods are based on perpetual inventory estimates of capital stock and corresponding estimates of capital service prices. Stocks and service prices are adjusted for relative utilization of capital. The resulting estimates represent a separation of income from capital into price and quantity components. Estimates of capital input in current and constant prices are constructed for corporate business, non-corporate business, and households and non-profit institutions in the United States for the period 1929–1967. These estimates are prepared in a form suitable for integration into the U.S. National Income and Product Accounts.     

A BALANCED SYSTEM OF NATIONAL ACCOUNTS FOR THE UNITED KINGDOM

This paper describes the construction of a disaggregated system of 262 national accounts for the U.K. economy in 1975. The objective is to remove the discrepancies between income, expenditure, production and financial estimates which occur in practice. This is done with the aid of a generalized least squares algorithm for adjusting national accounts with subjective estimates of reliability of the various account items. The balanced system of accounts provides the cross-section data base needed for the estimation of a consistent multisectoral dynamic model of the U.K. economy and yields the classification converters and input-output tables necessary for such a model.     

THE INTEGRATION OF MACRO AND MICRO DATA FOR THE HOUSEHOLD SECTOR1

National accounts in their present form do not serve very well as a framework for microdata, largely because of differing concepts and coverage in the macro and micro data. This article identifies the differences in sectoring and the handling of imputations and attributions between macro and micro data, and then proposes a form of presentation of the macro accounts that will facilitate their integration. Data for the United States in 1980 are used as an illustrative example. The final section explores the consequences of the proposed alterations in the macro accounts for the analysis of saving and investment and the accumulation and distribution of wealth, using U.S. data for the period since 1947. The article concludes that the proposed alterations do lead to new analytical insights, and further, that in their present form the national accounts are both misleading and inadequate.     

PRICES AND PRICE ANALYSIS IN THE FRAMEWORK OF THE NATIONAL ACCOUNTS

The paper discusses the role of prices in the framework of the new System of National Accounts (SNA) in terms of three major uses: (1) deflation, (2) price indicators, and (3) price analysis. Following a brief review of the price and quantity measures required by the new SNA with its emphasis on deflation of commodity flows and input-output accounts, in addition to the more conventional deflation of final demand categories, the paper discusses some of the conceptual, methodological and data problems involved in implementing the various uses of prices in the new SNA. Implementing the use of prices as deflators depends, in part, on the concept of output selected (national versus domestic; gross versus net), and which of six concepts of valuation, ranging from purchasers'value to true factor cost, is used. Some of the difficulties in deflating nonmarket flows (e.g., interplant transfers) and industry value added, based on the double deflation method, are discussed. In concept price deflators, which have shifting weights, cannot be used as price indicators, which should have fixed weights. In practice, this is often disregarded and the deflators are used as price indicators. The paper support the SNA recommendation for the development of price indexes with fixed weights to be used as price indicators, in addition to the implicit price deflators. Research in the United States indicates that differences in weights can result in different price measures for various subperiods, components of demand and sector output. Periodic revisions in weights to provide more current fixed weights for price and quantity indexes in each subperiod may minimize the problem but it introduces a new problem—lack of comparability with the constant price tables in the SNA which have fixed weights for the entire period. The new SNA provides a comprehensive and integrated framework for price analysis including the analysis of the structure of aggregate price changes, the industrial origin of final demand prices, and the impact of price change in one sector of the economy on the rest of the economy. Some major gaps which need to be overcome in order to implement the use of the new SNA for price analysis include the development of industry capital stock estimates, separate estimates of proprietors’income, reconciliation of value added and distribution share estimates, and the development of a wide variety of information to supplement the conventional input-output tables in the SNA. Implementing the various objectives of price measures within the framework of the accounts will require a number of improvements in existing price measures and expanding the scope of coverage. “List” prices should be superseded by “transactions” prices and better techniques and data need to be developed to provide for quality adjustment of prices. Coverage will need to be expanded to include services, freight rates, trade margins, government expenditures, and also fill in gaps for many manufactured products. Finally, where possible, use of unit values as price indexes or deflators, e.g., imports and exports, should be replaced by direct price measures.     

A REVIEW OF SELECTED ASPECTS OF THE UNITED NATIONS SYSTEM OF NATIONAL ACCOUNTS IN THE LIGHT OF COUNTRIES’ EXPERIENCES*

A review of the United Nations System of National Accounts and its implementation by countries is presently being conducted at the United Nations Statistical Office. This article presents a personal and selective account by the author of the results of that review and its consequences for the present structure of the SNA. Information is included on the level of response by countries for the tables of the SNA national accounts questionnaire. It shows that this response is at present sparce, except for the tables on GDP by end use, cost structure and kind of economic activity. On the more detailed level the feasibility of introducing integrated sector accounts into the system has been examined and different approaches compared. Country practices suggest that one way of facilitating the introduction of such accounts would be to eliminate one essential feature of the dual classification of the SNA, i.e., the distinction between quasi-corporate and other unincorporated enterprises. Other modifications of the SNA structure implied below are the introduction on a limited scale of articulation of transactions, the inclusion of additional aggregate income and balancing items, a reallocation of data between the main accounts and the supporting tables, and a better integration of the SNA matrix with the accounts and tables of the system. A reduction of the present number of independent classifications in the SNA is suggested, based on links between categories of different classifications that are assumed in country responses to the questionnaire. A suggestion is made for a uniform valuation of goods and services and income flows, to replace the present complex valuation guidelines on approximate basic and factor values and producers’ prices.     

ON THE TREATMENT OF TAXES AND GOVERNMENT IN THE NATIONAL ACCOUNTS

Framed in the context of the ongoing revision of the 1993 System of National Accounts (SNA), this note proposes a new presentation of the National Accounts. While it does not require new information, nor difficult calculations, it is suggested to be conceptually clearer and practically simpler. The changes concern the treatment of taxes and government in the national accounts which imply that: (i) GDP, measured at basic price, is now exactly the sum of all value added, which is split in the compensation of employees and an enlarged operating surplus; (ii) the two functions of government are clearly distinguished in a modified sequence of accounts, that is, as producing non-market services up to the allocation of primary income account, and then as redistributing the national income; and (iii) with a conventional allocation of government services and GDP broken down between market GDP and non-market GDP, households remain the only final consumer and the so called question of consumption subsidies is resolved.     

ACCOUNTING FOR THE TIMING OF FIRST MARRIAGE*

Among first marriages in the United States, grooms are on average 1.7 years older than their brides. Traditionally, this fact is explained by sex differences in income. We use a general equilibrium, overlapping generations search model economy to show instead that sex differences in fecundity are essential to account for the age gap at first marriage, whereas sex differences in income play a secondary role. Our model economy also accounts for other facts on the timing of first marriages that the literature has overlooked.     

ACCOUNTING FOR EXHAUSTIBLE RESOURCES IN THE CANADIAN SYSTEM OF NATIONAL ACCOUNTS: FLOWS, STOCKS AND PRODUCTIVITY MEASURES

The paper shows that the Canadian System of National Accounts includes exhaustible resources but treats them as if they were produced goods. Thus, the claim that conventional accounts ignore the contribution of exhaustible natural resources is partly true. To fully account for exhaustible resources, we present an alternative national accounting framework that incorporates natural resource flows and stocks. The framework modifies the measure of the net domestic product by a factor that differs from the Hartwick-Solow-Weitzman rule and leads to different estimates of GDP, national wealth, and productivity growth. An application to the Canadian oil and gas industry shows order-of-magnitude effects.
