CONCEPT AND DEFINITION OF INCOME IN THE NATIONAL ACCOUNTS

It is a truism that the national accounts have engendered their own concept of income which is different from other contexts such as business accounting, taxation or welfare analysis. Less known are the principles on which this income concept is based. This article is an attempt to specify such principles, investigating in particular the role of the transaction principle, and to derive an income concept therefrom. The crucial point of the argument is whether or not it is appropriate within the system of the national accounts to assign an income to sectors other than the households. The theory is applied to some practical questions which have been discussed in the process of the revision of the SNA.     

THE SOCIAL SIGNIFICANCE OF INCOME DISTRIBUTION STATISTICS

In both political discussions and scientific literature the income distribution has come to occupy a central position for the consideration of social welfare and economic equalization. It has been assumed that an individual's income reflects his consumption opportunities and therefore his standard of living or economic welfare. The thesis of this paper is, however, that there are reasons for being quite pessimistic about drawing meaningful conclusions from income distribution data. As illustrated by the use of Swedish data, the distribution of income gives an extremely incomplete picture of the distribution of consumption for a wide variety of definitional and statistical reasons. The distribution of consumption, furthermore, cannot be transformed into a corresponding distribution of welfare, since there is no well defined concept of welfare. The treatment of public consumption in empirical analysis of the distribution of welfare also raises problems. The paper closes with the presentation of the conceptual basis for an alternative to the traditional method of analyzing the distribution of income.     

THE DISTRIBUTION OF YUGOSLAVIA'S NATIONAL INCOME BY SOCIAL CLASSES IN 1938

This paper presents the results of an investigation of the distribution of Yugoslavia's national income by social classes in 1938. The population in mid-1938 was apportioned among social classes as follows: proletariat 34.6 per cent, middle classes 59.2 per cent, bourgeoisie 5.3 per cent, 0.9 per cent unallocated. About three-quarters of the population was rural. The proletariat amounted to 5.2 million persons, of which 3 million were peasants living on dwarf holdings and 2.2 million were rural and urban wage earners. Unemployment in the non-agricultural sector was 10 per cent; if the agricultural sector is added, overall un- and under-employment amounted to 31 per cent. The bourgeoisie consisted of 0.8 million persons, of which two-fifths were rich peasants. Of the 9 million persons in the middle classes, 7 million were peasants with small and medium holdings. The remainder were mainly minor entrepreneurs in the non-agricultural sector. The proletariat accounted for 35 per cent of total population but only 18 per cent of aggregate income, whereas the bourgeoisie with 5 per cent of the population received 26 per cent of aggregate income. The distribution of income among the various groups of the non-agricultural population was more unequal than among the groups of the agricultural population. Estimates are preesented of the distribution of income by various types and sources, for agricultural and non-agricultural population, together with income per capita, average earnings per employed worker, labor productivity, and capital intensity, the last by industrial branches as well as social classes.     

THE DISTRIBUTION OF INCOME AND WEALTH IN JAPAN

This paper reviews research on the distribution of income and wealth in Japan, identifies sources of data on income and wealth, and describes limitations of these data. Evidence that Japan's poorest income groups are relatively well-off is convincing, but there is less evidence that the overall distribution of income in Japan is more equal than in other OECD countries. Agricultural policy, social welfare policy, the tax system, trends in earnings differentials, and the role of the Japanese family are among the many factors that have shaped Japan's income distribution. The rapid appreciation of the stock market and land prices during the late 1980s led to greater inequality in the distribution of wealth. Rapid population aging is expected to lead to an increase in total national wealth relative to national income which may have an adverse impact on the distribution of income.     

THE ROLE OF MICRODATA IN THE NATIONAL ECONOMIC AND SOCIAL ACCOUNTS*

Microdata sets—samples of data relating to individual reporting units—can provide a valuable extension of the national economic accounts as they presently exist, making it possible to meet many of the criticisms being leveled at the accounts over their failure to include much nontransactions information that is essential to the evaluation of economic and social performance. To serve this purpose, however, the microdata sets must be integrated with the aggregate accounts, and with one another. A microdata sets relating to any given sector should add up (with appropriate weighting) to the economic constructs for that sector in the national accounts, and the microdata set for one sector should be articulated as appropriate with those of other sectors. This paper discusses techniques for constructing such microdata sets, including necessary adjustments of the macro accounts, techniques of alignment of microdata with the macro accounts and the creation and development of synthetic microdata sets. Synthetic matching and other techniques of merging data sets are discussed. The paper concludes with a consideration of the methodological implication of the integration of microdata and national accounts.     

AN INTEGRATED SYSTEM OF SOCIAL ACCOUNTS FOR AN ECONOMY OF THE YUGOSLAV TYPE

The system of social accounts described in this article is based on the following five principles: (1) Producers of goods and services are working organizations which represent groups of people or individuals organized for the purpose of earning a living by producing goods and services that satisfy individual or collective needs. Business, government, profit and nonprofit, corporate and unincorporated working organizations are treated in a uniform way. (2) Since the behaviors of the market and non-market sectors differ considerably, these two sectors are consistently separated throughout the accounting system. (3) There are four basic activities: (a) production, (b) consumption, (c) investment, and (d) income redistribution. These call for four separate accounts: (a) Working Organizations, (b) Households, (c) Community, including government and certain non-government institutions, and (d) Accumulation. The fifth account, Rest of the World, serves for balancing purposes. (4) The same classifications of transactions are used for activities and institutions, making possible complete matching of social product and financial flows accounts. (5) The system strives to achieve the maximum analytical flexibility. Some of its possibilities are visible from the classification of industries: A. Market (Material) Sector: 1. Agriculture, II. Forestry, III. Mining and Manufacturing, IV. Construction, V. Transportation, VI. Trade and Catering, VII. Handicrafts; B. Non-Market (Non-Material) Sector: VIII. Housing and Communal Economy, IX. Education, Culture, and Social Welfare, X. Public Services Social Organizations (Political, Religious, etc.), Finance and Insurance, Public Administration and Judiciary, National Defence. Sector A corresponds to the material definition of social product. Sectors A + B correspond to the SNA definition. Sectors A + B minus Industry × reflects the welfare definition. Further, Industries I-IV produce goods, V-VII market services, VIII and IX non-market services with welfare content, X intermediate nonmarket services, V-X all services.     

PRIM I: A MODEL OF THE PRICE AND INCOME DISTRIBUTION MECHANISM OF AN OPEN ECONOMY

PRIM I is a numerical model which has been extensively used as a basis for an income policy in Norway in recent years. It is a static, cost-push, input-output model. Wage rates, agricultural prices, productivities and world market prices are treated as exogenous variables, and the model derives short-term changes in income shares and in the national price level from changes in these exogenous variables. A key feature of the model is a distinction between "exposed industries" which are subject to strong foreign price competition, and "sheltered industries" which are relatively free of such competition. These two groups of industries are found to react with very different pricing policies in response to increases in costs; furthermore, possibly for technological reasons, the export industries have greater scope than the majority of the sheltered industries for compensating cost increases through productivity gains. These two facts are shown to have important implications for a price and income policy. It is demonstrated, i.a. that the goal of a stable national price level is, in general, inconsistent with the maintenance of stable income shares when exchange rates are kept constant.     

中国社会福利和收入再分配： 1988-2007年

基于中国居民收入分配课题组（CHIPs）1988-2007年的住户调查数据，本文分析了中国福利体系的大小、结构及其再分配性质。本文发现，中国的福利体系仍然存在巨大的城乡分割，城市居民的社会福利更全面，福利收入更丰厚，其福利水平接近于一些西方发达国家；而农村的福利制度则不完善，福利收入非常微薄。同时，城市的福利收入体系尽管近几年的再分配作用有所减弱，但总体而言是累进的，有效降低了收入不平等。而农村的福利体系几乎对收入差距的缩小没有影响，但从2007年的结果来看，农村累退的福利体系开始向累进的方向转变。农民工的社会福利收入在2002-2007年间大幅度增加，并发挥了巨大的再分配作用。     

THE INCOME UNIT AND THE ANATOMY OF INCOME DISTRIBUTION*

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.     

THE DISTRIBUTION OF HOUSEHOLD INCOME AND EXPENDITURE IN PORTUGAL: 1980 AND 1990

From 1980 to 1990 Portugal experienced a generalized liberalization of economic activity, due in large part to its 1986 integration in the European Union. This paper studies the changes in the Portuguese distribution of household income and expenditure during this period, using micro-data on household budgets and applying recent developments in statistical inference for Lorenz curves. We find a significant increase in six measures of welfare and an unambiguous decrease in the inequality of the respective distributions. Different explanations for the findings of decreased inequality are discussed.     

THE SIZE DISTRIBUTION OF INCOME IN LIBERIA

The economy of Liberia is one in which, in spite of past satisfactory growth performance, a high level of income inequality persists. In 1977, for instance, a mere 2 percent of the people accounted for some 33 percent of nation-wide wage income. These people live disproportionately in Montserrado County in which the capital city is located. While each of the other counties are largely rural and poor, each has far lower intra-county inequality than wealthy Montserrado.
Intersectoral location of the income-earner, average income levels and the extent of access to human capital formation opportunities are some characteristics of the economy that have been found to explain significant portions of intercounty variations in the levels of household income concentration. Income inequality is reduced with increases in the extent of agricultural activity as the share of the top income group falls and that of the bottom group rises. The reverse happens with growing urban-area activity. Higher income concentration occurs with rising per capita incomes as the top group's income share rises and the bottom income group's share falls. While this appears to be an instance of the Kuznet U-shaped hypothesis, here there are no definite signs of a possible reversal any time soon. The levels of access to educational facilities move inversely with the level of inequality, with expanding elementary facilities benefiting the poorer people at the expense of the wealthy while the reverse happens in the case of expanding secondary educational facilities.     

VERTICAL DIFFERENTIATION AND THE DISTRIBUTION OF INCOME

The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We show that overall more concentrated incomes imply stronger product differentiation, as the presence of a large share of middle‐income consumers stimulates a price competition, whose effects are dampened through an enlargement of the quality spread. While the high‐quality advantage and market coverage increase unambiguously in the degree of income concentration, the behaviour of prices is non‐monotone in the distribution parameter.     

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.     

SOCIAL PROTECTION ACCOUNTS AND THEIR RELATIONSHIP TO THE NATIONAL ACCOUNTS

The development of social protection accounts is described and the relationship between social security and welfare expenditure (as recorded in social protection accounts) and expenditures in the national accounts is discussed. Proposals are put forward for achieving co-ordination between social protection expenditure and expenditure recorded in the national accounts, and these are illustrated by reference to Irish data. The future development of social protection accounts by the inclusion of fiscal benefits, which are not recorded in the national accounts, is also considered. Finally some references are made to the use of the social protection accounts and the development of data relating o the numbers of persons covered by social protection and the numbers of beneficiaries.     

SOCIAL SECURITY AND THE INTRAGENERATIONAL REDISTRIBUTION OF LIFETIME INCOME IN JAPAN*

We investigate how social security redistributes lifetime income within the same generation in Japan, based on data from the micro data. The progressivity of Japan's state pension programme appears to be much more limited on a lifetime basis than on an annual basis. Given an ageing population, replacing the current Pay As You Go system with a simple one that consists of a flat benefit and a wage‐proportional premium, and has no maximum contribution, can be desirable in terms of both efficiency and intragenerational equity. The redistributive effects of income tax and consumption tax to finance the benefit are also examined.
