中国地区居民生活水平比较——基于全球夜间灯光数据

当衡量一国或地区居民生活水平时,统计学上一般有收入和消费两种视角。本文利用城乡住户调查中的人均可支配收入和国民经济核算中的居民消费水平,以全球夜间灯光数据为参照,综合收入端与消费端信息,对1997—2016年中国31个地区的真实生活水平进行比较分析。研究证实,灯光亮度与消费水平和人均可支配收入之间均存在显著的线性关系,可以用来估算真实生活水平。根据不同模型的回归结果得到,真实生活水平的最优无偏估计中消费水平的权重范围为（2795%,3831%）,人均可支配收入水平的权重范围为（6169%,7205%）。相对于消费水平,人均可支配收入更能准确地反映真实生活水平。本文进一步分析发现,样本期内居民生活水平增速小于人均GDP增速,可见经济的发展并未完全转化为生活水平的提高。中西部地区与东部地区的生活水平仍然存在巨大差距,东部地区的平均生活水平分别是中部和西部地区的17倍和21倍。     

HOUSEHOLDS, STANDARD OF LIVING, AND INEQUALITY

The standard of living of individuals does not depend so much on the income they themselves earn as on the total income of the household to which they belong and how the household organizes the use of its income. It is important to develop methods of income analysis which incorporate the household factor. In income distribution analysis, it is now common to take into consideration household size and composition in relative interpretations of income levels. In this paper it is suggested that the same methodology can be used for the purpose of absolute interpretations of income levels. The result is an alternative to per capita measures of standard of living which is sensitive not only to national income and population size, but also to household formation. This approach is applied to Norwegian data for the period from 1970 to 1986 as to trends in the average standard of living and standard of living inequality, and the redistributive impact of transfer and tax policies.     

GENERATING INTERNATIONALLY COMPARABLE INCOME DISTRIBUTION DATA: EVIDENCE FROM THE FEDERAL REPUBLIC OF GERMANY (1974), MEXICO (1968) AND THE UNITED KINGDOM (1979).

In this article an attempt is made to generate internationally comparable income distribution data for the Federal Republic of Germany (1974), Mexico (1968) and the United Kingdom (1979). To that end, the same income concept and income unit were adopted for each country, i.e. respectively household available income and the household. Moreover, incomes from various sources were adjusted for inconsistency with National Accounts according to Altimir's methodology. The paper finds that the distribution of persons by household income per equivalent unit is probably the best way of looking at the distribution of economic welfare. It further demonstrates that the distribution of persons by household available income per capita is much closer to this 'ideal' distribution than the distribution of households by household available income. Finally, the paper discusses some of the problems arising from the fact that one normally works with grouped data. It is found that in the case of the three countries under study, grouping is likely to have had only a small impact on the results.     

The second Engel law: Is it a paradox?

The second Engel law says that the Engel curve for food moves out as family size increases, thus showing a decrease in welfare. What is puzzling, though, is that this regularity does not hold for equivalent income functions expressed in per capita terms. Deaton and Paxon [1998. Economies of scale, household size, and the demand for food. Journal of Political Economy 106 (5), 897-930] show that holding per capita total household expenditure constant, per capita expenditure on food falls with the number of heads. Deaton and Paxson's empirical evidence from developed and less developed countries seems to invalidate the claim of the second Engel's law. The main objective of this paper is to understand such paradoxical relationship between food consumption and household size. Our nonparametric empirical evidence, drawn from the Colombian 1985 urban survey, shows that the food share is negatively related to total household per capita expenditure in line with Deaton and Paxson's claim, but equivalent incomes shift to the right as theory predicts. The regularity of our nonparametric results is an indication of a problem in the parametric specification of the Engel curve modified by family size. In fact, using also the surveys of Italy, Nepal, Djibouti, and Bangladesh we show that a theoretically plausible modified Engel curve is coherent with the claim of the second Engel law and explains Deaton and Paxson's paradox.     

Back to Engel? Some evidence for the hierarchy of needs

Using UK household expenditure data spanning over four decades (1960–2000), this paper employs Engel’s needs-based approach to analyzing household expenditure patterns and finds evidence for the existence of a stable hierarchy of expenditure patterns at low levels of household income. Second, we investigate how rising household income influences the manner in which total expenditure is distributed across Engel’s expenditure categories. Our results suggest that i) total household expenditure is distributed across Engel’s expenditure categories in an increasingly even manner as household income increases and ii) over time, there has been an acceleration in the rate at which household expenditure patterns become diversified as household income rises. Finally, we consider how the shape of Engel Curves may help shed light on the relationship between goods and the underlying needs they serve.     

THE DISTRIBUTIONAL CONSEQUENCES OF GOVERNMENT SPENDING AND TAXATION IN THE U.S., 1989 AND 2000

We assess the effects of government expenditures and taxation on household economic well-being in the United States in 1989 and 2000. Net government expenditure is estimated as the difference between government expenditures incurred on behalf of the household sector—transfers and public consumption—and the taxes paid by that sector. We incorporate the estimates of net government expenditures into a wealth-adjusted measure of income. We find that overall inequality in our income measure is considerably reduced by net government expenditures. Results from decomposition analysis show that the inequality-reducing effect of net government expenditures owed more to expenditures than to taxes.     

A COMPARISON OF POUND STERLING-AUSTRALIAN DOLLAR PURCHASING POWER PARITIES FOR SELECTED POPULATION SUB-GROUPS IN AUSTRALIA AND THE UNITED KINGDOM1

This paper utilizes Household Expenditure Survey and Consumer Price Index data supplemented by private survey data in an attempt to compare the purchasing power parities of the pound sterling and the Australian dollar for a range of population sub-groups in the United Kingdom and Australia. In spite of the close political, economic, social and cultural ties that exist between these two countries, there have been no attempts to measure differences in living costs and real expenditures. Further, Australia has not been a party to the International Comparisons project of the Statistical Office of the United Nations. This study derives purchasing power parities which explicitly account for variations in expenditure patterns of different population sub-groups. For example, a household living in London intending to move to Sydney will find it useful to have a comparison of cost-of-living between households living in these two cities which takes into account explicitly the general expenditure patterns in these two cities. Due to the nature of the data, it was necessary to employ a new index number method derived by one of the authors.     

AN ESTIMATE OF THE SIZE ANL STRUCTURE OF THE NATIONAL PRODUCT OF THE EARLY ROMAN EMPIRE

On the basis of rough estimates from the expenditure as well as from the income side, it is suggested that the national product per head of the Roman Empire at the death of Augustus (AD 14) was somewhat below 400 sesterces (31 g gold) yielding an aggregate national product of fully HS 20 billion for a population of 55 million and that these figures were approximately valid from the late first century BC to the mid-second century AD. The share of government expenditures in national product was very low, probably not above five percent, and that of gross capital expenditures even lower, probably not in excess of two percent. An attempt is also made to appraise the concentration of personal income and it is estimated that the 600 senatorial families, representing approximately the top 0.04 per m of the population, received about 0.6 percent of total personal income while the share of the top three percent of income recipients was in the order of 20–25 percent of total personal incomes. The second part of the article compares these estimates as well as a few indicators of the standard of living and of welfare in the early Roman Empire with the corresponding figures for a few countries before the industrial revolution and for mid-20th century less developed countries.     

The oil price increase and the alleviation of poverty: Income distribution in Caracas,Venezuela, in 1966 and 1975

Two Caracas household budget surveys are used to compare household and individual income distributions. Real 1975 incomes are derived from income-specific price indexes. Minimum food budgets define destitution and poverty levels. During 1966–1975 mean real income rose substantially, especially among the rich. The fraction poor declined markedly, but mean income did not rise for those remaining poor. The poor's share of income growth came entirely from reduction in the number of poor, and exceeded their 1966 income share. The poverty gap expanded with population growth but shrank in per capita terms and relative to total income.     

SOCIAL ACCOUNTS AND THE DISTRIBUTION OF INCOME: THE MALAYSIAN ECONOMY IN 1970

Although the functional and institutional distributions of income are integrally connected to individual living standards and other development policy objectives, these dimensions are rarely given prominence or even accommodated within standard national accounting frameworks. This paper summarizes research on the estimation of a social accounting matrix (SAM) for Malaysia for 1970 in which the distribution of income between different factors and socio-economic groups is identified. It is the latest of a series of case studies involving some of the authors and is, perhaps, the most detailed of its kind. The study departs from the United Nations SNA guidelines at various points. The SNA basically proposes a commodity balance approach to national income accounting. In giving equal emphasis to income/outlay accounts as to the production accounts, the present study has brought together data from two major primary sources: a household expenditure survey and a production survey. Their combination poses several problems which are discussed in the paper. It leads to an integrated picture, in matrix form, of the interrelationships between income distribution and production structure in the Malaysian economy. Both the factor and household accounts in our SAM are disaggregated according to race and the geographic distinction between Peninsular and East Malaysia, with an urban/rural split within Peninsula Malaysia. The Peninsula labor force is further disaggregated by education level, while its households are then subdivided according to the employment status of main income earners. Arguments for and against these choices are presented. Some other aspects of the study can be noted. First, the distinction drawn between East and Peninsular Malaysia is desirable not only because of the inherent interest of the regions but also because of large differences in data availability and hence in estimation methods. Secondly, to complete our SAM it was necessary to estimate inter-household transfers, being the institutional analogue of inter-industry commodity flow. And finally an attempt has been made to impute the labor component of unincorporated business income. These, then, are the major problems which had to be overcome in our attempt to quantify the generation, distribution, and redistribution of income within Malaysia in a SAM framework.     

COMPARING INCOMES WHEN NEEDS DIFFER: EQUIVALIZATION FOR THE EXTRA COSTS OF DISABILITY IN THE U.K.

Equivalization of incomes for household composition is accepted practice when measuring poverty but other variations in needs are rarely acknowledged. This paper uses data from two U.K. household surveys to quantify the extra costs of living associated with disability. The extra costs of disability are derived by comparing the "standard of living" of households with and without disabled members at a given income, having controlled for other sources of variation. Logit and ordered logit regressions are used to estimate the relationship between a range of standard of living indicators, income, and disability. The extra costs of disability derived are substantial and rise with severity of disability. Unadjusted incomes significantly understate the problem of low income amongst disabled people, and thereby in the population as a whole.     

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

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

The impact of natural disasters on household income,expenditure, poverty and inequality: evidence from Vietnam

Natural disasters are expected exacerbate poverty and inequality, but little evidence exists to support the impact at household level. This article examines the effect of natural disasters on household income, expenditure, poverty and inequality using the Vietnam Household Living Standard Survey in 2008. The effects of a natural disaster on household income and expenditure, corrected for fixed effects and potential endogeneity bias, are estimated at 6.9% and 7.1% declines in Vietnamese household per capita income and expenditure, respectively. Natural disasters demonstrably worsen expenditure poverty and inequality in Vietnam, and thus should be considered as a factor in designing poverty alleviation policies.     

二次分配对城镇居民收入差距的调节效果分析——基于2007—2010年安徽省城镇住户调查数据

本文利用安徽省城镇住户调查数据探讨了二次分配对城镇居民收入差距的调节效果。研究表明,个人所得税和最低生活保障制度对收入差距的调节效果微乎其微;社会保障支出在一定程度上缩小了可支配收入的基尼系数,但是考虑到单位对住房公积金、养老保险、医疗保险的配套支出,最终的结果扩大了城镇居民的收入差距;目前,养老金和退休金对调节收入差距的效果最为显著,但是养老金和退休金的收入差距也比较大。     

NEW INSIGHTS INTO THE STRUCTURE OF THE WORLD ECONOMY*

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

More or better? Measuring quality versus quantity in food consumption

As people become richer they get the opportunity of consuming more but also qualitatively better goods. This holds for a basic commodity like food as well. We investigate food consumption in Russia, taking into account both expenditure and nutrition value in terms of calories. We analyse how food consumption patterns change with increasing income by considering both “quantity Engel curves” and “quality Engel curves.” The former describe the functional dependence of calories consumed on total expenditure. The latter trace out the dependence of unit value per calorie on total expenditure. We compare income elasticities of quantity with income elasticities of unit value and quality. In Russian household survey data for years 2000–2002 the reaction of quality to income changes is significantly stronger than the reaction of quantity to income changes suggesting that Russian households tend to choose higher quality food items as income rises.     

Trends in real income in Britain: A microeconomic analysis

Trends in real national income are typically assessed using aggregate indicators such as GDP per capita, or mean household income, whereas the income distribution literature focuses on trends in income inequality. By contrast this paper takes an integrated approach to real national income measurement; it uses methods incorporating both size and distributional considerations, and applies them to household income microdata in order to measure changes in real income in the U.K. during the 1980s. A parametric class of decomposable real income indisces is proposed which complements quasi-ordering methods such as rank and generalised dominance criteria by telling us how much real income increased over the period (if at all). The indices are also additively decomposable by population subgroup, a property which helps reveal who the gainers and losers were. The analysis also draws attention to the normative and statistical issues raised by the presence of a few very small incomes.     

TRENDS IN AGGREGATE HOUSEHOLD WEALTH IN THE US., 1900–83

New estimates of aggregate household wealth for the U S. covering selected years in the period from 1900 to 1983 are presented. I find that marketable wealth per capita grew at 1.46 percent per year in real terms over the 1900–83 period, while real wealth per household grew at 0.81 percent per year. However, the growth rate was not uniform over the period, with the rates high during the 1900–29 and the 1949–69 periods, and slow during the other years. Moreover, real per capita wealth actually increased more slowly than real per capita disposable income and real per capita GNP over the century. I also find dramatic changes in the composition of household wealth over the century. In particular, both tangibles and fixed claim assets increased relative to total assets over the period from 1900 to 1983, while equities fell from about half to a quarter. Owner-occupied housing increased only moderately as a proportion of assets, from 17 percent in 1900 to 20 percent in 1983. Unincorporated business equity fell from over a third of total assets to 12 percent. Among financial assets, the biggest relative growth occurred in deposits in financial institutions, which grew from 8 percent in 1900 to 22 percent in 1983. Corporate stock had the most volatile behavior in the household portfolio, growing from 13 percent of total assets in 1900 to 27 percent in 1929, falling to 10 percent in 1949, rising to 22 percent in 1965, and then falling to 11 percent by 1983. Debt as a proportion of total assets rose from 5 percent in 1900 to 16 percent in 1983. Finally, both pension reserves and social security wealth increased relative to marketable assets from virtually zero in 1900 to 12 and 48 percent, respectively.     

A PROTOTYPE MICRO-MACRO LINK FOR THE CANADIAN HOUSEHOLD SECTOR

This paper seeks to forge a link between Canadian macro and micro data relating to the household sector. The analysis is in three parts. The first part begins with National Accounts data on the personal sector. These data are adjusted to remove transactions relating to non-biological persons, so that the result is income and expenditure for the household sub-sector. The second part starts with the annual household survey used to collect income distribution data. These survey data are augmented in various ways to account for under-reporting and to add information from other micro data sets particularly the periodic survey of household expenditure patterns and a sample of individual income tax returns. The result is a comprehensive, albeit partially synthetic, household micro data set. In the final part of the paper these two largely independent data sets are compared, and the general quality of the results is discussed.     

Revenue and Progressivity Neutral Changes in the Tax Mix

There has been much debate about the redistributive implications of a consumption tax and the treatment of low income households. This article presents a general model which allows for the interdependence between income and consumption taxes, while allowing for transfer payments to the low paid. The appropriate adjustment of transfer payments in response to a change in the tax mix, in order to maintain a fixed real value of transfers, is examined. The use of exemptions, of those goods for which the proportion of expenditure falls as total household expenditure rises, in order to increase the progressivity of consumption taxes is also considered. The model enables changes in the tax mix, which are both revenue and progressivity neutral, to be devised.
