Notes: The calculation of purchasing power parities and quantity comparisons for a given year provides interesting information about the relative importance of countries. However, it is necessary to make these estimates annually in order to enable users to apply these parities for international comparison of annual data expressed in national currency. The paper deals with the problems related to merging spatial comparisons and temporal volume and price movements for the countries of the European Community. For these countries full information was collected in 1975 and in 1980, whereas in the intermediate years some price data were collected and price indices at a detailed level have also been collected. First the theoretical problems of consistency between the spatial results and temporal indices are discussed. Because no immediate consistency can be obtained, several methods are proposed to achieve consistency, by estimating one unique set of spatial and temporal indices. The available information for the period 1975-80 has been used in order to test the numerical differences between two sets of parities and price indices over time. Besides theoretical reasons for inconsistency, it is also necessary to take into account errors in the price observations or in the price indices. The results presented in the paper should be considered as provisional and further work will be undertaken to obtain better insights into the inconsistency between these sets of data.

Notes: To know the size and development of the hidden or underground economy is important for policy making, mainly because the measures undertaken may be misdirected if they are based on biased official statistics. The hidden economy can be measured by considering indicators. The direct methods are based on voluntary surveys and on tax auditing and other compliance methods. The indirect estimation methods rely on the identification of residuals with respect to income and expenditures, as well as in the labor and money markets. The strengths and weaknesses of each of these measurement approaches are discussed and the resulting estimates of the size of the hidden economy are compared. A different approach to measurement is to look at the determinants leading to the existence and growth of the hidden economy. Finally, the method of “unobserved variables” allows the combination of the two approaches by simultaneously considering the determinants and indicators of the under- ground economy. The results show a considerable range of sizes for a given country and year. Though there is a broad range of size estimates, there is general agreement that the hidden economy's size has been growing for all countries over recent decades. Further progress in quantitative knowledge about the hidden economy requires the development of a theoretical model which analyses the interdependencies between the official private sector, the hidden economy, and the public sector.

Notes: This paper explores the imputed service price approach to the pricing of the services of consumer-owned-and-used durables in the construction of the consumer price index, using the services of owner-occupied housing as an illustration. A theoretical framework for analyzing this question is first developed. Certain practical problems are then discussed. The conceptual difficulty of constructing an appropriate rate of return on the basis of available data on interest rates and house prices, in the context of inflation, is explored. Two arguments are advanced that statistical agencies ought not to follow the imputed service price approach in pricing the services of owner-occupied dwellings and other consumer durables. On the one hand, nominal interest rates will, in any short period, reflect monetary policy and not any change in the money “rental” of owner-occupied houses. Second, movements in nominal interest rates will also reflect changes in the money price of pure consumption goods, as well as changes in the money price of houses. The argument is extended to other consumer durables and, in the limiting case, to monetary balances, and it is concluded that in all but trivial cases the application of the service price approach leads to price movements of little or no meaning.

Notes: This paper uses a variety of assumptions to produce calculations of worldwide income distributions from recent international data compilations. The variable quality of the source materials in these compilations along with the arbitrariness in the assumptions required are emphasized. A number of working hypotheses for the worldwide income distribution are offered until data and methods improve. It is suggested the top 1 percent of world population may receive 10–15 percent of world income, the top 10 percent from 45–65 percent, and the bottom 20 percent from 1–4 percent. These figures seem more unequal than those for domestic distributions even for more inegalitarian countries.

Notes: Using data from the German Socio-Economic Panel, we compare income mobility of persons from the eastern and western states of Germany between 1990 and 1995. We consider income mobility between consecutive years and between the first and the final year of this time period. We find that gross individual labor income mobility was much higher in the east than in the west during the first years after reunification, but that this difference has become much smaller until 1995. Changing to measures that reflect economic well-being more accurately, we observe that gross equivalent labor income mobility and net equivalent income mobility initially were also much higher in the eastern states than in the western states, but converged over time as well. This convergence has been particularly strong for net equivalent income mobility, suggesting that the social protection system has greatly reduced mobility risks associated with the transformation process in the eastern states of Germany.

Notes: The precautionary saving literature shows that income uncertainty increases savings and wealth. To estimate the magnitude of this effect, we need a measure of income uncertainty. This paper empirically analyzes subjective income uncertainty in The Netherlands. Data come from a large Dutch household survey. We measure income uncertainty by asking questions on expected household income in the next twelve months. First, we describe the data and investigate the relationship between the measure of income uncertainty and a number of household characteristics. Controlling for information on expected income changes, we find strong relationships between labor-market characteristics and the subjective income uncertainty as reported by the heads of the households. Second, we compare income uncertainty in The Netherlands with income uncertainty in the U.S. and Italy. It becomes evident that perceived income uncertainty is smaller in The Netherlands than it is in the U.S.

Notes: Precautionary savings models suggest that wealth should rise with income risk. Risk is reduced by means-tested transfers, however, which implies that transfer programs should discourage private wealth accumulation. We offer a comprehensive empirical assessment based on variation across states in the generosity of a number of programs, specifically unemployment insurance and means-tested transfers (Aid to Families with Dependent Children and Food Stamps). We use monthly data on married couples from the Survey of Income and Program Participation (SIPP) to regress wealth on income, income risk, and various measures of transfer generosity. The results support the precaution-ary savings model and reveal moderate negative wealth effects of both unemployment insurance and means-tested transfers, with an elasticity of about −0.18.

Notes: The first set of hours of work estimates constructed for Canada and its regions for the 1880–1930 period is presented in this article. These estimates suggest a trend decline in hours of work, especially following First World War. In addition, these estimates suggest that the decline in hours of work came at no or little cost in terms of real weekly income. The trends uncovered for Canada are found to be similar to those revealed for the U.S. In effect, by the early twentieth century workers were realizing their long expressed preferences for a shorter workweek at no loss in real income.

Notes: A simple regression of personal income per capita for the U.S. states is estimated from cross-section data for the years 1929, 1950, 1970 and 1990 with each state's distance from the equator as the regressor. While proximity to the equator is noted to have a sizable adverse effect on income, elasticity of personal income per capita with respect to “tropicality” shows a steady and somewhat dramatic decline during this 60-year period. The estimates indicate that the disadvantage of tropicality is not immutable, and need not imply a developmental determinism.

Notes: Income redistribution studies on the macro–economic level have been undertaken in Denmark for the years 1938–39, 1949, 1955, and 1963. By use of national accounts figures and all other available statistics, it was on certain assumptions possible to distribute public sector income and expenditure by income groups.A quite different approach is used in a Danish redistribution study on the micro-economic level for 1971, which relies solely on the comprehensive data from the family budget survey for that year. Unfortunately this study only relates to employee households.This paper deals with the 1963 and 1971 studies. First it describes and discusses the differences in methodology between the two studies and indicates some ideas for future studies in this field in Denmark. In the following sections some main results of the two studies are given, briefly for the 1963 study and more comprehensively for the 1971 study. The studies show the great and growing strength of the policy of redistribution through public sector income and expenditure in Denmark.It is the opinion of the authors that the appearance of redistribution studies based on comprehensive family budget surveys makes for a substantial improvement of redistribution figures, and that the purely micro-level frame of reference makes it possible to interpret the results in a more satisfactory way than before. Furthermore, the appearance of detailed input-output based national accounts data should bring about further improvements in redistribution figures through better data on indirect taxes and subsidies as well as supporting data which are necessary to link the micro and macro levels in a consistent way.

Notes: It is often discussed that inflation introduces a substantial, arbitrary and regressive redistribution of income and wealth under even mild inflation. But after a quarter century of experience with inflation in postwar Japan, very little is known about these costs of inflation on an empirical basis. Due to the complexity of the evaluation of the redistributional impact on Japan, the present paper analyzes the effects of inflation on individuals or groups as wage earners, debtors and creditors, taxpayers, and holders of real estate.The main results of the present investigation suggest that the Japanese inflation for 1955–75 did not seem to introduce much inequality in the income (flow) account in the economy, but that the inequality between households has appeared more in the wealth (stock) account, especially between the house-owner groups and non-house-owner groups. These observations are mainly derived from the following investigations; (i) the wage lag hypothesis about inflation, even if not wrong, does not seem acceptable when applied to the entire period (1955–75) as well as to each of the five sub-periods; (ii) there has been a substantial transfer of real purchasing power from households to non-financial corporations, and, to a lesser extent, to government entities in the debtor-creditor redistribution; (iii) among households, the most substantial redistribution takes place from the non-houseowners to houseowners with land, because of the huge amount of capital gains from the rapid increase in the price of real estate relative to the prices of other assets or the consumer price index, except for the last three years of rampaging inflation.

Notes: Preliminary estimates of the total incomes system of accounts (TISA) are provided for 1959 and 1969. They extend conventional accounts to include all consumption services produced by government and households as well as by enterprises, but define household purchases of durable and semi-durable goods as investment. Acquisitions of capital throughout the economy, intangible as well as tangible, and not only in the business sector, are included in capital accumulation along with, for tangible capital, net revaluations, that is capital gains net of increases in the general price level. Imputations are offered for non market consumption and capital accumulation, most prominently in unpaid household work and education. Much of government output, particularly police services and defense, is recalculated as intermediate, along with expenses related to work, while media services, treated by the United States Bureau of Economic Analysis (BEA) as business purchases of intermediate product, enter into TISA consumption. Subsidies are included in the value of product, as are services of volunteers and imputations for the underpayment of military conscripts and of jurors. Separate accounts are offered for the national income and product, business, nonprofit institutions, government enterprises, government and households.The ratios of BEA to TISA Net National Product were 81.4 percent and 76.5 percent in 1959 and 1969, respectively. BEA national income was 74.1 percent of the corresponding TISA net national income in 1959 and 69.6 percent in 1969, reflecting a greater per annum rate of growth of TISA net national income, 7.49 percent, as against 6.82 percent for the corresponding BEA national income.BEA gross private domestic investment, restricted to business acquisitions of tangible capital at original cost, was estimated as only approximately 22 percent of comprehensive TISA gross domestic capital formation in 1959 and some 20 percent in 1969. The BEA net private domestic investment growth rate of 7.32 percent per annum from 1959 to 1969 may be compared with a TISA net domestic capital formation growth rate of 9.42 percent.

Notes: The paper is concerned with the concept, definition and measurement of a service. Although services are often dismissed as immaterial goods, they are not special kinds of goods and belong in a quite different logical category from goods. The search for appropriate units of quantity in which to measure services is not an idle metaphysical pursuit. Without quantity units there can be no prices, and most economic theory becomes irrelevant. Indeed, large parts of economic theory may be irrelevant to the analysis of services anyway, precisely because they are not goods which can be exchanged among economic units. Services are as important as goods in modern developed economies and they need to be identified and quantified properly if the measurement of economic growth and inflation is to have any meaning for the economy as a whole. The concept of a service is explained in some detail in the paper, and various ways in which services can be classified for purposes of economic analysis are elaborated. The distinction between private and public goods, or rather between private and collective services, is re-examined in the light of the general concept of a service proposed in the paper. Externalities are shown to be simply special kinds of services.

Notes: Additivity is an important property for the aggregation methods used in constructing purchasing power parities. For a practical definition of additivity, this paper categorises all aditive methods. First of all, a generalisation of the Geary-Khamis method of aggregation is defined: this is called the Generalised Geary-Khamis, (GGK), approach. The key result proved is that, within a broad class of possible aggregation methods, the set of additive methods is precisely equivalent to the set of GGK indices. Some implications of this categorisation of additive methods are considered, both in the multilateral and bilateral cases. For example, in the multilateral case, the Iklé index is set in context as another special case of the GGK approach. In the bilateral case, it is shown that there always exists a GGK, (and therefore additive), equivalent to the Fisher Index.

Notes: National accounting issues related to forest resources have attracted much attention recently. The net-depletion method, the most popular method for estimating aggregate changes in the value of timber stocks, tends to overstate both the depreciation of mature forests due to harvests and the appreciation of immature forests due to growth. Alternative, correct methods, which I term the net-price and El Serafy variations, can be derived from an asset valuation model that takes forest age into account. An empirical example indicates that estimates from the net-depletion method can deviate from actual values by up to 40 percent for some age classes.

Notes: This article examines several hypotheses concerning the stochastic nature of year to year variations in individual incomes in light of newly available microdata on individual earnings. In particular, the models of Solow (1951), Champernowne (1953), and Rutherford (1955) are examined in some detail, and their predictions as to changes to be expected in the distribution of individual incomes are tested. The author concludes that the distributions arrived at using these models are not very similar either to each other or to the actual distribution of earnings. Thus, he believes that as an “explanation” of earnings dynamics stochastic process models are unsatisfactory. He further criticizes these models on the grounds that they foster a bias toward the belief in the inevitability, and perhaps desirability, of the current distribution of earnings.

Notes: This paper investigates the relation between schooling and earnings across and within occupations. Across occupations earnings are positively related to mean education. Within occupations the variance in schooling levels is generally substantial, but within two thirds of the occupations no relation between schooling and earnings is observed, while in the remaining third the pattern of sensitivity varies considerably. The sensitivity of earnings to education is greater for white males than white females and substantially greater for whites than blacks. When the white sample is divided into age cohorts, the degree of sensitivity of earnings to schooling is found to be greater for younger cohorts than older ones, except for the youngest cohort in 1970. In the conclusion, a structural interpretation of the distribution of earnings is proposed to account for the findings.

Notes: The historical background and present methodology used in compiling the U.K. official estimates of the stock of fixed capital are described. Mention is made of the possibility that with the development of commercial accounting direct estimates of capital stock may be derived from enterprise accounts at some future time. For the present, however, an indirect perpetual inventory approach is followed. Some of the deficiencies of the present estimates are discussed including the effects of possible biases in the life-length assumptions, price indices and the treatment of secondhand assets. Estimates of gross capital stock are given analysed by industry group of ownership and by type of asset.Some conceptual issues are discussed in relation to user requirements, including the distinction between the stock of capital and the flow of services from it.The authors conclude that little can be done to improve the perpetual inventory estimate of fixed capital in the U.K. without devoting more resources to the collection and analysis of new information, particularly on the service lives of fixed assets, the extent of leasing and the transfer of assets between industries.

Notes: This paper is concerned with the theoretical problems of devising indexes of quality change and with some of the practical problems of constructing such indexes from market data, relating these to the various attempts to construct such indexes in the past. The general conclusion is that, while quality is inherently ordinal, there are three different indexes which might be taken as “measures” of quality change. If changes are sufficiently small, the values of all three indexes will coincide and then, only, can we consider any one of them to be an unambiguous measure of the change.

Notes: This paper assesses the effects of including wealth and the variability of income on the incidence of poverty and the degree of income inequality in Israel. A special survey, which includes data on the wealth and income of a national sample of Israeli families in 1963–64 and 1964–65, allows us to go beyond measures based on current income alone.The first section reviews earlier studies of poverty in Israel. The next section looks at poverty and inequality in terms of current income, current wealth, and a combined measure of income and wealth. The combined measure is the Hansen-Weisbrod measure (HW), which equals income plus the annuity value of wealth, assuming all wealth is just consumed at the time of death. It is interesting that, in spite of the much higher wealth inequality than income inequality, the HW measure was slightly more equally distributed than income. This result occurred because the annuity component made up a low share of the total HW measure and the correlation between income and wealth was well under 1. Although overall inequality and poverty were similar for income and HW measures, the incidence of poverty by subgroup depended on the measure used.The final section presents a dynamic view of poverty and inequality. Year-to-year changes in poverty were substantial. Because of the use of a relative poverty concept and the rise in real incomes, the real income poverty line rose by 15 percent between 1963 and 1964. Still, of those in income poverty in 1963, 37 percent managed to escape poverty in 1964. The paper shows how the degree to which poverty was stable or transitory varied substantially by age and country of origin.

Notes: We examine the sensitivity of U.K.-Spanish poverty comparisons to variations in the dependence of equivalence scales on household size and composition, using evidence from national household budget surveys. We sum up these comparisons using subjective confidence levels. Taking into account the dissimilarities in the distribution of incomes and needs across countries, we find, inter alia, that although the poor are typically more numerous in Spain than in Britain, the actual headcount differences may vary by up to 10 percent of the population when needs allowances are altered, even when kept the same across the two countries. Comparisons of poverty composition across the two countries are also very sensitive to the choice of equivalence scale parameters. Generally, however, the proportion of single adults among the poor is much less important in Spain than in Britain, the reverse being true for households with three or more adults.

Notes: At the first residential conference of the Institute for Fiscal Studies, which was held at St. Edmund Hall, Oxford, in September 1983, Mr Stewart Bates, QC, spoke on the implications of the decision of the House of Lords in the case of W. T. Ramsay Ltd v CIR. A report of those proceedings was held over until the decision of the House of Lords in the case of Furniss, v Dawson was known. The following report is based upon Mr Bates' address and the comments of Mr Stephen Oliver, QC, Mr John Avery Jones and Mr Adrian Shipwright who spoke at a lunchtime seminar convened by the IFS on 9 March 1984 to consider the decision in Furniss v Dawson. This report does not reflect the opinions of the IFS, which has no corporate views.

Notes: Income inequality is examined using the Panel Study of Income Dynamics and a consistent decomposition analysis. I only use inequality measures that satisfy the Principle of Transfers, have the property that a ceteris paribus increase in inequality within any subgroup increases overall inequality, and are independent of the scale of income and population. Decompositions are carried out by family size and by age of head for several definitions of income and income recipient. Whilst changing the time unit over which income is measured has a substantial impact on inequality, the effect of removing the between-age-group component of inequality is relatively slight.

Notes: This paper discusses Austria's experiences in connection with the 1980 round of the UN International Comparison Project, in which comparisons were first made within regions and the regions then linked. Austria played a dual role, as (a) the linking country between Group I (the European Community) and Group II (selected middle and eastern European countries), and (b) the base country for Group II. The paper consists of two principal parts. The first part reports, at the 3-digit commodity level, on the success achieved in finding comparable items, both within Group II and between Austria and Group I. The second part discusses a number of methodological problems that were encountered in carrying out the comparison. Chief among these was the treatment of social services that are marketed in some countries and provided free of charge or at nominal prices in others. Other questions touched upon include the treatment of output for own consumption, rents, drugs and medicines, and tourist expenditures.

Notes: Lack of a conceptual basis for measuring human capital investment in health has hampered efforts to expand national accounting systems to include human capital investment. This paper presents a conceptual basis for developing estimates of this health investment, an estimation methodology consistent with the conceptual basis, and preliminary estimates for the United States for 1952-78.While much work remains to be done before comprehensive estimates of investment in health are achieved, it is clear that previous estimates based on answers to the question, “What improves health?” have included some inappropriate expenditures while excluding others that should be included.The conceptual basis presented here leads to a methodology for separating health care costs (not the costs of illness) into maintenance and gross investment. Gross investment can be further separated into net investment and the sum of damages and depreciation but empirical implementation of this step is not attempted here.

Notes: This paper describes the construction of an accounting matrix for the world economy in 1977, cast along similar lines to SNA National Accounts, but one in which trade flows replace inter-industry flows as intermediate demand. The matrix distinguishes ten regions. Institutional accounts are presented for three of these, the European Community, North America and Japan. This matrix is used to provide the basis of a linear model in which average propensities to import and consume are replaced by estimated marginal propensities. Use is made of standard estimates of the income effects of terms of trade changes in order to distinguish substitution from income effects in the model, and a means is suggested for separating the full as well as the impact effects of a terms of trade change into income and substitution effects. The estimated import equations are used to derive estimates of regional growth rates compatible with external balance in each region. Multiplier matrices are calculated from the model showing regional interdependence of the world economy reflecting the pattern of trade which is identified in the marginal propensities to import.The effects of various aid policies are calculated using the model. It is shown that the cost of aid to any region is radically altered by taking into account the feedback effects of changes in demand. A policy of tied aid pursued by EEC, North America and Japan can actually lead to an improvement in Japan's balance of payments position. Finally the effects of movements in relative prices are illustrated by means of two examples.

Notes: The persistence of poverty and income inequality in less developed countries (LDCs) is a source of serious concern to development economists. To understand the structure of inequality, several researchers using a variety of methodologies have measured the importance of various contributory factors to overall income variability. The available literature—which now includes studies of Brazil, Mexico, Iran, the Philippines, Taiwan, Thailand, Pakistan, and Colombia-has been reviewed elsewhere (Fields, forthcoming). This paper presents additional evidence for urban Colombia, in the process raising some important methodological issues which bear on the design of future research studies.The data set used in this paper is described in Section I. The decomposition of Colombian inequality by functional income source is presented in Section 11 for micro data. Section I11 examines the robustness of source decomposition procedures to data aggregation. Section IV presents inequality decompositions by city, and Section V by other income-determining characteristics. Conclusions appear in Section VI.

Notes: Using a simple simulation model, this paper assesses the impact of relative movements in asset prices on the distribution of wealth during the 1969–75 period. Because of the strong negative correlation between wealth level and the ratio of debt to wealth, this particular inflation induced a substantial drop in the overall level of wealth inequality. Moreover, comparing the portfolios of different demographic groups, we found that middle-aged households gained relatively to younger and older ones, married couples gained relatively to singles, whites gained relatively to non-whites, and home-owners gained relatively to renters. The biggest gainers from this inflation were home-owners with large mortgages and the biggest losers the large stock holders.

Notes: Responding to a perceived growing interest in human wealth estimates, this paper offers a framework for measuring the aggregate stock of human capital and then implements the procedure for the United States male population age 14 to 75. Unlike previous estimates of human wealth that are based upon historical or resource costs, these estimates measure the capital stock as the discounted resent-value of expected lifetime returns. In the estimation, returns are equated with earnings data from the 1970 U.S. Census 15 percent Public Use Sample for out-of-school males, adjusted for employment and survival probabilities, adjusted for an assumed exogenous growth in future earnings, and discounted at 7.5 percent.We provide cross-sectional estimates of individual stocks of human capital by age and educational attainment, as well as expected lifetime wealth profiles for individuals by level of education. These individual profiles can be used to obtain direct estimates of age-specific depreciation which suggest human capital is subject to significant and prolonged appreciation before nearly straight-line depreciation begins around middle age. This finding is all the more significant since resource-cost estimates of human capital which must assume a depreciation pattern to obtain stocks have always imposed a much faster rate much sooner.Finally, an aggregate estimate of the stock of human capital for all males is supplied and its sensitivity to the choice of the discount rate, tax laws, and expected exogenous growth is analyzed. This seemingly-conservative stock estimate is then compared to a much lower resource-cost estimate offered recently by John Kendrick. A discount rate over 20 percent would be needed to equate the two measures. In trying to reconcile the two figures, we raise some new questions about the validity of both approaches for human capital accounting.

Notes: This study is concerned with an effort to analyze changes in costs and prices in the Australian economy by tracing the effects of changes in wages and import prices through the stages of production, using a disaggregated input-output model with lags. The object of constructing the model was to improve, by introducing lags, the accuracy of predictions of the effect of cost changes on prices, and to show the lag structures. Data problems encountered are discussed, and the need for integration of price statistics to enhance their usefulness for analyses such as this is emphasized. Concepts and sources of data are discussed in some detail in an appendix.

Notes: For some considerable time the interest in price statistics has mainly been focused on their use as “intermediate goods”. The requirements of a system of price index numbers which have to be established in this connection are largely in the field of statistical coordination (integration of statistics on quantities, values and prices).Recently the inflation problem has given rise to an increased interest in price statistics as “final goods”. A meaningful analysis of inflation will devote attention to the relation between input prices and output prices. In this article several versions of an analysis of prices of final demand categories based on an ordinary Leontief input-output scheme are presented and the needs for price statistics are discussed. In fact a self-contained system of price statistics emerges from the price analysis.There is a difference in the nature of the price index numbers required in compiling input-output tables in constant prices (Paasche) and that in the case of price analysis (Laspeyres). However the need for price observation runs largely parallel because in both cases the same detailed information on price developments will probably be used.Price analysis gives the possibility of a step-by-step approach in building up a system of price index numbers.

Notes: This paper is in 7 sections. Section 1 gives as background a chronological account of the steps taken in the United Kingdom, from 1974 to late 1977, towards the development of a new system of accounting in company reports which would allow for the effect of changing costs and prices on the measurement of profit and of capital employed in the business. Section 2 discusses the main features of the system, known as current cost accounting, as it is seen in the United Kingdom. Section 3 surveys the relationship between current cost accounting and the national income and expenditure statistics, and the likely implications of the introduction of current cost accounting upon the quality of macro-economic statistics, including estimates of national and sector balance sheets. Section 4 describes some of the problems of implementing current cost accounting, particularly in special situations, and outlines the solutions which were proposed in the “Exposure Draft” published in 1976 by the accountancy profession in the United Kingdom. Section 5 considers the definition of distributable profit in relation to the need to maintain capital, considering the concept of gain, the system of valuing assets and liabilities, and the enterprise's capacity to take on additional debt as a means of financing its assets. Section 6 briefly surveys the implications for taxation, price control and price setting. Section 7 concludes by surveying the scene at the end of 1977 and by looking at likely future developments.

Notes: This article explores the assumptions underlying present definitions of national income in its principal uses, and considers the alterations that would be needed to allow for the inclusion of environmental quality. A numerical example illustrates the impact of alternative measures. The discussion concludes that if we want national income to conform more closely to theoretical concepts of welfare indices, then we need to include a proxy for those environmental services that would not be completely free goods if it were possible to overcome their inherent non-marketability. The least unsatisfactory proxy would be the spending on environmental protection.

Notes: This paper examines the causes and consequences of the inflationary process in terms of its impact upon the national accounting flows, illustrated by the case of France during the period 1966–76. The first section of the paper discusses the apparent causes of inflation, and lays out the circuits through which inflation is propagated. The second section looks behind the apparent causes to examine more closely the reasons for the observed behavior. The final section considers the consequences of inflation in terms of factor allocation, and in turn its impact upon unemployment, the balance of payments, and the rate of growth.

Notes: In the June 1977 issue of the American Economic Review extraordinary attention was given to the statistical problem of measuring the effect on inequality in current income arising from differences associated with age. The method adopted by Paglin was severely criticized although everyone recognized the value of Paglin's unusual, if not original, emphasis on the importance of the underlying issue.This paper is not primarily concerned with the statistical problem of correcting data on current income distributions for income-age differences. It is concerned mainly with the lifetime income perspective itself-with ways of viewing the long-term path of persons and of ways of viewing inequalities in that path as they develop within and among different generations.The paper discusses issues of measurement on a birth-cohort or longitudinal basis, recent trends for selected cohorts, intra-and inter-cohort variances in lifetime income, and various policy issues, for example, the equity of the U.S. Social Security System viewed on a lifetime dimension.

Notes: The main purpose of this paper is to discuss some of the measurement problems in connection with the perpetual inventory method applied for estimates of capital stock. In the Federal Republic of Germany, highly aggregated capital stock data by business sector are compiled by the Federal Statistical Office within its national accounts calculations, while more detailed capital stock estimates by industrial sectors are published by the German Institute of Economic Research (DIW) in Berlin. Because of various gaps in the statistical sources, the accuracy of the capital stock calculations is not yet entirely satisfactory. Aside from the problem of establishing long time series for gross fixed capital formation in constant prices for all sectors, it is difficult to obtain reliable data on the inter-sectoral transactions in secondhand capital goods. In addition, there are problems of determining price indices and service life distributions of the fixed assets in the various parts of the economy. This paper shows a way to arrive at a reasonably close approximation to the latter problem.

Notes: Recent attempts to measure value of household work and other non-market activities have been based on a simplistic interpretation of Opportunity Cost of Time Theory; this paper attempts to refine this and develop practical definitions from basic Utility Theory. First a distinction is made between economic and other activities, the former being the only ones subject to dollar-measurement; we recognize economic activities can occur outside the market and focus our analysis upon these latter. In the framework of Becker-Lancaster a Household-Production Function is posited which produces jointly such non-market economic activities-called indirect utility-and welfare or satisfaction- called utility. A criterion for identifying the indirect utility activities (Third-Person Criterion) is outlined, and related to time-use survey data.Finally, four practical estimation methods are outlined: simple opportunity cost of time; gross replacement cost; individual function replacement cost; and the full production function approach. This latter, which includes evaluation of capital contributions, is deemed theoretically most valid but for present purposes least practical because of lack of data on domestic capital stock. The paper concludes that there exists both a theoretical basis for valuing non-market activities, and the necessary data to apply the formulas developed.

Notes: This paper compares the growth accounting approaches to aggregate productivity measurement and analysis of three major researchers: E. F. Denison, D. W. Jorgenson, and J. W. Kendrick. The investigetors are compared in terms of their treatment of a number of crucial elements, including measurement of output and of capital and labor inputs (including composition or quality changes), total factor productivity growth, economies of scale, and intensity of demand (for output). Judged by the standard of the neoclassical economic theory of production-the only generally accepted basis for input aggregation-Denison departs significantly from the production theory framework in his measurement of output and capital input, Kendrick to some degree in his measure of capital input, and Jorgenson not at all. The effects of these departures are illustrated with reference to the recent productivity slowdown. The probable near-term future utility of growth accounting methods for productivity analysis is assessed, and some related econometric modeling issues are noted.

Notes: This article reviews the problems involved in updating the results of international comparisons, in terms of an analytic framework focusing upon the sources of differences between various forms of extrapolation and direct comparisons. The factors identified as important are conservation of prices of the base period and weight inconsistency. The reliability of updating is undoubtedly affected by the length of the period over which the data are extrapolated. A program of regular benchmark comparisons at approximately five-year intervals with updating for the intervening years is attractive, since it permits checking by forward and backward interpolation. Where there are large deviations, however, averaging is not an acceptable solution.

Notes: Index number accuracy is affected by formula specification and sampling error. The authors argue that an index formula should be “ideal” and “exact” (with reference to the range of economically plausible aggregator functions) to be economically justified. These indices are invariant in the homothetic case, as well as in certain non-homothetic scenarios. Empirically, based on foreign trade data for Egypt from 1885-1961, the set of economically justified indices are virtually identical, supporting the theoretical argument that “instrumental error” or “formula variance” should be a negligible factor contributing to index number error. In a discussion of sampling error, on the other hand, the authors criticize earlier work and propose an upper and lower bound. Using the same data, these limits imply that sampling error may be a serious problem for many indices.

Notes: The United Nations (SNA) and the Canadian (CSNA) Systems of National Accounts treat interest as a factor return to capital. The difficulties arising from the use of this concept cast doubt upon the basic premise. For example if the usual method of measuring value added by the summation of primary inputs is applied to industries mainly engaged in the lending of money, the results show negative production. This has led to the necessity of imputing bank interest in order to avoid negative income originating in the banking industry. Arguments are being put forward to extend this practice to certain other financial non-bank areas as well to offset the negative product emerging with increasing frequency as a result of higher levels of interest transactions.The proposed alternative is based on the contention that interest paid and received for the borrowing and lending of money should be treated in the same manner as the purchase and sale of other services. For the production accounts, for example, this would mean that interest paid by business would be treated as an intermediate expense of the paying industry and as revenue of the receiving industry. The adoption of this approach would therefore eliminate the need for the imputation of banking services and clear up the ambiguities encountered in treating interest on the public and consumer debt, issues which are also not unrelated to the present treatment of interest.

Notes: The present investigation is the first attempt to calculate gross capital stocks for 19 industries which together cover the whole Austrian economy. A production-oriented concept of capital formed the basis of the investigation; the estimation procedure follows that of C. Almon et al. In contrast to the traditional perpetual-inventory methods, Almon's modified estimation technique combines the advantages of differentiated cumulation containing a logistical retention function with relatively moderate requirements with respect to investment data. A thorough description of this estimation technique is given in the third section of the paper, combined with a number of comparative model calculations. These demonstrate very clearly that capital stock figures calculated according to the Almon method rarely deviate from those found with the help of the traditional inventory method, which requires considerably more information and uses more complicated calculation procedures. Finally, the sectorally disaggregated capital stock estimates calculated according to the Almon method are presented with some interpretative remarks.

Notes: It is increasingly acknowledged that the financial structure of a firm is an important determinant of its production costs. This paper argues that the use of a firm's liabilities should be seen as a separate input in the production process. At the same time, the input of non-financial assets is limited to the value that is used up during the reference period. The paper elaborates on these ideas and shows their use in empirical work. It is concluded that the approach set out in this paper establishes a much closer relationship of general economic accounting and analysis to business economics.

Notes: This paper uses a series of cross-section surveys to measure how wealth accumulation and active saving rates varied across cohort-groups during the early and mid 1990s. Our estimated rates of saving and wealth change across cohorts show a somewhat more dramatic life-cycle pattern than found in previous studies, in part because we use a new technique, and in part because the cross-section wealth surveys we use oversample the wealthiest families whose behavior dominates aggregate changes. Adjusting the wealth-change rates for bequests and subtracting out the capital gains component of wealth change move the estimates in the direction of results from previous studies, but the biggest changes in that direction result from excluding the top of the wealth distribution in each year.

Notes: Inequality comparisons require equivalence scales to account for differences in household size and composition. The multiplicity of equivalence scale models makes the sensitivity of the inequality calculations to the scale used a significant policy issue. Such an investigation based on unit records of two adult households from Italy, Australia, South Africa, Thailand, Peru, Philippines, India and Tanzania was our principal motivation. The equivalence scale varies across countries and between different types of children. Inequality rankings of countries, though not the inequality decomposition between households of different composition, are robust to the equivalence scale used.

Notes: Many central statistical offices use indirect time series disaggregation methods to produce quarterly national accounts estimates or other high frequency variables. This paper investigates the relation existing between the statistical properties of indirectly estimated time series and the contemporaneous aggregation level at which estimation is carried out, when a version of the Chow-Lin (1971, 1976) method is used to evaluate quarterly time series. It is shown that estimation at the lowest possible level of contemporaneous aggregation is not always optimal. In order to choose the level of contemporaneous aggregation at which time series disaggregation should be carried out, the use of formal econometric tests is suggested.

Notes: Several different approaches to international comparison of Total Factor Productivity (TFP) have now emerged. Among these are the time-series approach, the panel approach, and the cross-section approach. This paper compares methodologies of these different approaches and results that have been obtained from their application. The comparison of results is conducted in the context of two samples, namely the sample of G7 countries and a large sample that includes developing nations. It is found that while there are broad agreements in results, there exist considerable differences too. The analysis shows how these differences can be related, in part, to differences in methodology. The paper also shows how these different approaches to international TFP-comparison can play a complementary role in enhancing our understanding of such important phenomena as technological diffusion and TFP-convergence.

Notes: This paper first shows, with data from fourteen countries, the potential of time-use studies for measuring, in comparable physical quantities, labour inputs in SNA and in non-SNA production. It then presents the monetary valuations of unpaid household labour and of households' non-market product achieved on the basis of time-use data in a few of these countries. Further elaboration of these valuations illustrates the contribution of households' non-SNA production to extended private consumption. The conclusion suggests desirable future developments.

Notes: In a recent issue of this journal, M. Luisa Ferriera, Reuben C. Buse, and Jan-Paul Chavas argue that the equivalence scales implicit in the official U.S. poverty line and in public welfare programs overcompensate parents for their children, with resulting negative distributional and incentive effects. We show that their analysis is based on a very particular, and ethically unappealing, assumption about the importance of children's well-being.

Notes: The main purpose of this paper is to relate the empirical attempt of measuring output from the education sector to theoretical results about the welfare significance of an extended net national product (NNP) measure. We show that economic theory provides a more focused way of interpreting such output estimates, which has not been recognized in previous studies. The paper also contains new estimates of the output from the Swedish education sector.

Notes: This paper analyses the treatments proposed by Chapter XIX (Annex B) of the 1993 SNA and the manual Inflation Accounting published by the OECD (Peter Hill) as alternatives to the traditional recording of nominal interest. Real interest and interest prime (annex B) are relevant for different purposes. Their amounts are not the same to the extent that actual compensation and full required compensation for inflation differ. The recording of negative real interest is not compatible with the exclusion of holding gains/losses from the SNA current accounts. The accounting treatments in Inflation Accounting (capital transfers, additional lending/borrowing, no nominal holding gains/losses) and Annex B (nominal holding gains/losses, no capital transfers, no new lending/borrowing) are contrasted.

Notes: This article reports on the plans of the member countries of the Council for Mutual Economic Assistance (CMEA) in the area of the purchasing power parity comparisons of national product and similar aggregates. A series of comparisons of the U.S.S.R. with other individual member countries was made for 1959,1966, and 1973. A new series will be undertaken for the year 1978. The scope of the program will be expanded to cover several new aggregates, including productivity concepts and total consumption of the population. The article discusses the conceptual and methodological problems and plans. Among other matters, attention is being given to the possibility of reducing the number of specifications priced, without sacrificing accuracy.

Notes: The problem of identification and classification of off-shore financial flows and extra-territorial funds is discussed with special reference to the case of the “captive” insurance market in Bermuda. The problem is examined in the context of the UN SNA definitions relating to the evaluation of insurance activities and the difficulty of gaining access to relevant and complete data. The conclusion is reached that the conduct of off-shore financial operations by local institutions and the resulting surpluses generated remain essentially extranational and thus contribute very little to the domestic value added of the tax haven concerned. Furthermore, by its very nature, information relating to the transactors involved, as well as the value of their transactions, is difficult to obtain. This raises a much wider issue, however, as to whether such surpluses are ever identified in any country's national income estimates.

Notes: This paper has two main points. First, the usefulness of the industry detail called for in the SNA would be increased if it were altered to facilitate the construction of price and quantity aggregates classified by stage-of-process sectors. Second, the price and quantity data so arranged should be augmented by data on behaviorally related variables classified the same way. The feasibility of the stage-of-process approach is demonstrated by a table showing the high degree to which the U.S. input-output table for 1967 can be triangularized. The analytical usefulness of the approach is demonstrated through analysis of changes in prices, output, unfilled orders and finished goods inventories for primary and for finished goods manufacturers.

Notes: This article proposes a method of characterizing the growth process using two parameters, a production index measuring growth, and a structural change index measuring the changes in the composition of output. It discusses the properties of the structural change index that is developed, including its relation to the bias in growth rates measured by conventional index numbers. It then applies the measure to an examination of Yugoslav industry for the period 1952–71.

Notes: Expanding a conventional national accounting framework in order to include activities that are not produced or consumed via ordinary markets requires the accountant to adopt some procedure for assigning unit values to these activities. Often, as is the case with governmental services, unit values are equated with unit costs of production.This paper argues that the appropriate valuation generally differs depending on whether the activity is viewed from the perspective of the producer, the consumer, or society. The theoretical justification for this position is developed first for the case of nonmarketed environmental services and then for in-kind governmental transfers.Rather than choosing a single unit value, the paper argues for and outlines an accounting system that will permit the simultaneous adoption of more than one valuation. Techniques for implementing the system for the environment and for in-kind transfers are discussed.Finally, drawing on the experience of the authors, the paper argues for the importance of developing data sets with more than one valuation. The authors claim that the effort to implement the system has generated valuable ancillary data sets even though data limitations and unresolved methodological questions have precluded complete implementation.

Notes: Starting out from the observation that both imports and exports may be viewed as the difference between domestic consumption (use) and production, static standard theory of biases in consumption and production indices is brought to bear upon trade indices: Laspeyres tends to overrate when applied to imports and to underrate when applied to exports; for Paasche, the opposite holds true. Hence, terms of trade tend to be underrated (exaggerated) when based upon Laspeyres (Paasche) price indices. The problem of extending these conclusions to the case of changes in production frontiers and preference maps is discussed. When homotheticity is absent, correlation between price and quantity relatives may upset the simple conclusions. This is of special importance in the large-country situation. Dynamics further complicate the situation. A cobweb mechanism in exports may thus reverse the static results.

Notes: This article considers the major results of a study of relative wage structures in the LAFTA region. It first discusses the nature and methodology of the study, which was undertaken for ECIEL. Data on the size of labor income differences are introduced, and an attempt is made to determine the causes of such differences, and to relate them to various wage differentials. The main findings of the study are then summarized, with discussions of inter-country, intra-country, and occupational labor income differentials and their causes. Finally, the results of the study are updated to the end of 1970, and some conclusions are derived regarding the inter-temporal behavior of wages in LAFTA.

Notes: Some relationships between NNP and economic welfare are explored in the confines of a simple, static welfare maximization model. Various assumptions concerning both the measurement of NNP and the economic system underlying this model are dropped seriatem and the implications for the correspondence between NNP and economic welfare are examined.The following conclusions emerge. There are several classes of resource reorganization in which NNP and welfare move in the same direction, so that NNP can serve as an ordinal proxy for welfare. These include changes in taxes or competitive imperfections which result in product substitution and movements along the transformation function.With a general qualification, NNP-welfare correspondence is preserved for allocative changes which affect the real costs and prices of goods included in NNP or of non-included goods in inelastic demand; changes in involuntary unemployment; and changes in technological externalities affecting producers. There are other cases where changes in NNP and welfare are not positively correlated. Included here are changes in real costs of non-included goods for which demand is elastic and changes in technological externalities imposed on consumers.

Notes: The purpose of this paper is to describe the conceptual and statistical basis of the estimates of United States public and private spending for pollution abatement and control (PAC) prepared by the Bureau of Economic Analysis, U.S. Department of Commerce. The concepts and definitions were designed to ensure comparability with the national economic accounts since much of the analysis of the effects of environmental programs on the economy is conducted with the aid of the accounts. The work to date has been limited to pollution associated with harmful “foreign” substances and forms of energy discharged in the course of production, distribution and consumption. The conceptual base includes evaluation of benefits, but estimates completed thus far are limited to the cost of pollution abatement and control.Definitions are given for pollution, pollution abatement, direct pollution abatement cost, indirect pollution abatement cost and indirect benefits. A framework for the estimation and presentation of PAC expenditures is developed and the estimate of U.S. PAC expenditures for 1972 and 1973 is presented. A brief chronological summary of the BEA project is also provided.

Notes: This paper computes new indexes of output for refrigerators, using hedonic methods to adjust for quality change. The hedonic technique is applied in a new way (it is used to make quality adjustments to prices before they are used in the index), and the results are compared with those from methods used in previous hedonic investigations.There are three major findings. (1) Overall (1960–1972), our hedonic deflated output series rise more rapidly than conventional measures, because the price indexes used for deflation rise more slowly. (2) The output measures fluctuate more than do output measures produced by conventional methods, because adding hedonic quality adjustments to WPI indexes moves them up in some years and down in others, and the resulting adjustments to the output series were positively correlated with changes in output. (3) Applying methods used in previous studies produces larger adjustments to the published indexes, suggesting that some of the differences noted in previous studies between hedonic indexes and official published indexes are related to computational methods, not to quality adjustment.

Notes: This paper focuses on a neglected aspect of the treatment of the income unit in the construction of size distributions of income. If the size distribution is to be an indicator of the distribution of economic welfare, and if the economic welfare of each individual in society is to count equally, then conventional distributions are inconsistent with individualistic welfare functions. We estimate size distributions with each person's welfare weighted equally, and contrast these results with those weighting each household unit's welfare equally. The choice of weights is shown to affect both the level and the trend in income inequality.

Notes: This paper reports upon the first official application of the estate multiplier method of estimating the wealth distribution to French data. It is based upon a sample of estate duty returns filed during the period September-December 1977. The sampling rate was 5 percent for estates under one million francs, and 100 percent for estates over this level, giving a total of 5031 records. The data available did not permit a breakdown by type of asset. It did, however, permit classification of estates by age, sex, and occupation of decedent. Experiments were conducted using five different sets of mortality multipliers. The set of mortality multipliers judged most appropriate leads to an estimate of aggregate net wealth that is 77 percent of that given in the national balance sheet of the national accounts. Comparison of the distributions of wealth derived in these estimates suggest that the figures are consistent with those found in other countries.
