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.     

本地非农就业、外出务工与中国农村收入不平等*

随着巨大的经济和社会变革,中国的收入不平等程度发生了巨大变化。依据CHIP家庭微观调查1988-2007年的数据,使用基尼系数分解以及非参数分解等多种方法,本文试图对本地非农就业、外出务工等不同类型的家庭从业模式与农村收入不平等的关系进行较为全面的探讨。研究得出了一些有价值的结论：首先,从整体的收入分布来看,早期的农村地区的发展更多伴随着不平等程度提高,而后期经济增长则带来更多福利改善;其次,家庭主要非农收入来源是本地非农就业,外出务工所得具有缩小收入差距的作用,而本地非农就业则具有扩大作用,随着时间推移其作用程度也有所改变;最后,经济增长成果惠及不同群体,但并非平均分配,不同群体获益情况不同,增长和不平等通过作用于不同类型家庭影响到最终的收入分布。

THE SIZE DISTRIBUTION OF FAMILY INCOME IN U.S. SMSAs, 1959*

An attempt is made in this paper to identify and quantify the relative influence of several economic, social, and demographic factors on variations in the size distribution of family incomes in 208 Standard Metropolitan Statistical Areas (SMSAs) in the United States in 1959. Using a simple ordinary least squares model with Gini's concentration ratio (R) as the proxy for family income inequality, the estimating equations explain up to 89 percent of the SMSA-to-SMSA variation. The “best” explanatory variables are those having to do with size of nonwhite population, occupational structure, and median years of education. City size and region—which are represented by dummy variables—are also revealed as playing an important role, both on their own and in conjunction with other of the independent variables.     

INCOME DISTRIBUTION IN THE U.S.S.R. IN THE 1980s

In 1989 Soviet authorities released unprecedented new data on the size distribution of income in the U.S.S.R. in the 1980s, including the distributions by republics. With the goal of providing a benchmark for evaluating the effect of current and future economic reforms on income distribution in the former Soviet Union, this paper estimates inequality measures for the new data. The estimation uses a simple nonparametric technique based on the Kolmogorov-Smirnov test to fit the Soviet data to a lognormal distribution. The results suggest that, for income from official sources, (1) inequality in the Soviet Union as a whole declined throughout the 1980s-both before and after Gorbachev's accession in 1985, and (2) income inequality was greater in the poorer, southern republics of the U.S.S.R. than in the north. While the inclusion of unofficial (unreported) private income would probably reinforce the second of these two trends, its effect on the first cannot be determined on the basis of available information.     

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.     

DISTRIBUTION OF ECONOMIC RESOURCES: IMPLICATIONS OF INCLUDING HOUSEHOLD PRODUCTION

The value of household production is estimated to 40–50 percent of GNP in most western countries, and because the distribution of this income-in-kind is different from ordinary income distribution, the concept of economic well-being may include household production. The monetary value of household production is evaluated by a market alternative principle and an opportunity-cost principle. In the last case a reservation wage is estimated, and integrated in a modified opportunity principle, which means that household work of non-working women is evaluated by the reservation wage, and household work of working women and men by their wage-rate. The conclusions are among others, that the inclusion of household production reduces the inequality, and that the women's contributions—money income and household production—functions as income equalizers.     

HOUSEHOLD SAVING IN THE U.S.

In this paper the authors present evidence on household saving in the U.S. based on the panel data from the 1983 and 1986 waves of the Survey of Consumer Finances. Saving is measured in these surveys as the change in wealth over the three-year period. Using a variety of models, we are able to explain only about 7 percent of the variation in the level of saving. Demographic factors appear to be modestly useful in explaining saving. However, one fact is very clear from the patterns of correlation extracted so far: either the measurement error in the data is quite large, or idiosyncratic factors are very important in explaining saving behavior, or both.     

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 SIZE DISTRIBUTION OF HOUSEHOLD DISPOSABLE WEALTH IN THE UNITED STATES

In this study, new estimates are presented of the size distribution of household wealth in the U.S. in 1969. Compared to previous studies, its major advance is the inclusion of all marketable or discretionary household assets and liabilities and their alignment with national balance sheet totals. Household disposable wealth (HDW) is defined as the sum of all marketable or fungible assets held by households less liabilities. The Gini coefficient for HDW is 0.72, the share held by the richest one percent of households is 31 percent, and the share held by the top five percent is 49 percent. There is, however, a large variation in the concentration of different household assets. The Gini coefficient is 0.30 for household durables and inventories, 0.69 for equity in owner-occupied housing, 0.94 for bonds and securities, and 0.98 for corporate stock. HDW is then divided into two mutually exclusive components. The first, called "life-cycle wealth," is defined as the sum of equity in owner-occupied housing, durables, household inventory, demand deposits and currency, and the cash value of life insurance and pensions less consumer debt. This form of wealth tends to be accumulated over the life-cycle for either consumption, liquidity, or retirement purposes. The second, called "capital wealth," is the sum of time and savings deposits, bonds and securities, corporate stock, business and investment real estate equity, and trust fund equity. Life-cycle wealth is substantially less concentrated than capital wealth. The Gini coefficient for it is 0.59, while that for capital wealth is 0.88. Moreover, among the lower wealth groups, over 80 percent of household wealth takes the form of life-cycle wealth, whereas among the top wealth groups the proportion is under 20 percent. The results suggest substantially different savings motivations between the two groups.     

THE DISTRIBUTION OF INCOME BETWEEN SOCIO-ECONOMIC GROUPS IN THE NETHERLANDS

This paper reports on a study designed to improve the information on income flows and income distribution in the Netherlands national accounts by building a bridge between the national accounts and income tax statistics. The methods used are described in some detail, and the significance of the results obtained is discussed. The figures show rather substantial fluctuations in the share of proprietors relative to that of wage earners. This result is not unexpected, since the share of proprietors is much more sensitive to the level of economic activity, but it does limit the usefulness of the figures for short-run economic policy determination. In the longer run, however, they do show what the development of the average incomes of the various social groups has been, and to what extent government action has contributed to that development.     

MEASUREMENT ERROR IN THE BANK OF ITALY'S SURVEY OF HOUSEHOLD INCOME AND WEALTH

This paper is aimed at evaluating the incidence of measurement error in the Bank of Italy's Survey of Household Income and Wealth (SHIW). In the case of time-invariant variables, we assess the degree of inconsistency of answers given by panel households in subsequent survey waves. For quantities that vary with time, we estimate the incidence of measurement error by decomposing observed variability into true dynamics and error-induced noise. We apply the Heise model or the latent Markov model, depending on whether the data are continuous or categorical. We also present regression models that explain the error-generating process. Our results are relevant to researchers who use SHIW data for economic analysis, but also to data producers involved in similar income and wealth surveys. The methods we describe and test can be employed in a number of contexts to gain better understanding of data-related problems and plans for survey improvement.     

HOUSEHOLD PRODUCTION AND NATIONAL PRODUCTION: AN IMPROVEMENT OF THE RECORD

1 By no means is the home based production of housewives the only or even the most important aspect of nonmarket production. The entire question of work vs. leisure, and the distinction between leisure and nonmarket oriented production, are currently under intensive scrutiny. See for instance the work of Nordhaus and Tobin [7, especially appendix section A.3], Gronau [2] and items cited in Gronau. The omission from the national income accounts of work performed at home by males, non-married females, and “working wives” is extremely important. This paper is concerned only with married females because (1) they are the subject of what must be one of the oldest jokes in the subject of social accounting, and (2) the relationship of production by housewives to total production has changed in the past ten years or so, and that deserves some attention even if it is not the most important thing which has been happening with respect to the GNP.
Specifically, we will present estimates of the value of home based nonmarket production by housewives. These estimates will then be used to supplement various national product aggregates in order to calculate more accurate growth rates for the U.S. economy. We find that the value of nonmarket production by married women during the 1960's has averaged approximately thirty percent of the GNP and close to 40 percent of the national income. The inclusion of the nonmarket work of housewives in GNP would reduce the measured rate of growth of real GNP per potential worker by about ten percent, the exact amount depending on how the value of nonmarket work is estimated. Our estimates indicate a reduction in the absolute rate of growth of almost 0.25 percent.     

THE IMPACT OF CAPITAL GAINS ON THE DISTRIBUTION OF INCOME IN BELGIUM

In an earlier paper, we presented estimates of capital gains for a number of categories of assets owned by Belgian households. The purpose of the present paper is to see how the distribution of disposable income between socio-economic groups is modified when one adopts a "broadened" definition of income which includes capital gains corrected for losses of purchasing power.
The main result of the study is that at current prices, the adoption of a broadened definition of income strongly increases disparities between socio-economic groups. However, when one takes into account losses in purchasing power, conclusions differ according to the period analyzed. For the years 1953–68, it appears that the distribution of broadened disposable income is more unequal than the distribution of disposable income. For the years 1969–77 when inflation was high, the adoption of a broadened definition of income has reduced disparities, with the important exception of old age pensioners.     

我国税制结构对居民收入分配影响的分析与思考

我国国民贫富差距较大已是不争的事实。尽管政府在税收方面采取了很多政策举措,希冀对居民收入分配进行调节,但效果并不十分理想,其主要原因在于我国当前的税制结构并不利于缩小贫富差距。以流转税为主体的税制结构使税制整体呈现出累退性,个人所得税对工薪收入的过分关注以及对财产性收入调节的缺位,增强了个人所得税制收入分配逆向调节的特征,财产税的缺失导致富裕家庭大量财产游离于政府税收制度调节之外。
