DATA SOURCES ON INCOME DISTRIBUTION IN BANGLADESH, INDIA, PAKISTAN AND SRI LANKA: AN EVALUATION

This paper examines the data base available in four South Asian countries, India, Pakistan, Bangladesh, and Sri Lanka, for the examination of trends in real inequality and poverty. Taking the position that sample surveys of household income and consumption are the only really adequate bases on which size distributions of income for a less developed country can be constructed, the paper examines in Section I the reliability of the surveys available in the four countries. Section II evaluates available price data. Section III looks at directions for future development of data collection. The conclusion is reached that sample surveys regularly conducted in these countries do not provide a particularly good basis for this type of analysis. Needed alterations include permitting access to the primary data (or redesign of published tabulations to meet the needs of this type of analysis), use of per capita rather than total household income and consumption, better coverage of regions and occupations, and exploitation of the price data implicit in the survey data collected. Further, the surveys themselves need to be overhauled, especially with regard to timing of interviews. The paper concludes with a short discussion of alternatives to estimates of inequality that can be used to measure absolute deprivation, such as the QUAC stick for identifying nutritional insufficiency.     

INCOME DISTRIBUTION STATISTICS IN LATIN AMERICA AND THEIR RELIABILITY

This paper is addressed to the question of how far income distribution statistics currently available in Latin America can be relied upon, either to assess the degree of inequality in the national distribution of income or to undertake comparisons between countries or over time. It gives a summary account of research carried out on Latin American data.
The sources available in Latin America for estimating income distributions are discussed. Concentrating the attention on household surveys conducted in various Latin American countries, an inventory of such surveys and their characteristics is offered, along with a detailed exposition of survey methods and income concepts used for estimating household income. Methods used for assessing the representativeness of samples are summarily reviewed. The case for comparing income data from household surveys and population censuses with national accounts estimates is put forward, along with the procedures and assumptions used for carrying out such comparisons. The relative discrepancy between the two sources is taken as indicative of the degree of underestimation of each type of income in each survey. An analysis of such discrepancies across the set of surveys considered gives clues on possible underestimation biases in measuring each type of income and total household income in different types of survey and in population censuses.
Differential effects on comparability of survey results call for appropriate methods of adjusting income distribution estimates to account for the missing incomes. A method for carrying out such an adjustment is applied to income distributions from a selected number of Latin American surveys. The results obtained provide an indication of how much difference it makes to use unadjusted or adjusted data to assess income concentration or to carry out comparisons over time or space.     

MEASURING INEQUALITIES: DO HOUSEHOLD SURVEYS PAINT A REALISTIC PICTURE?

The paper addresses the issue of the accuracy of standard‐of‐living measurements using household survey data. First, it highlights the fact that lighter data collection processes in some developing countries have added to measurement errors in consumption and income aggregates measurement errors. The paper reasserts the need to apply reference guidelines to the measurement of household consumption in order to compute comparable distribution indicators across countries and over time. Second, it contends that it is hard to analyze inequality solely from consumption patterns without taking income and savings into account. Two solutions are proposed for the correction of income measurement errors: by using savings declarations and by implementing a multiple imputation procedure. The results are based on a careful analysis of the EPM93 survey of Madagascar whose design is quite close to the LSMS household surveys, and the ENV98 survey of Côte d'Ivoire representative of surveys conducted nowadays in most Sub‐Saharan African countries.     

MEASUREMENT OF THE DISTRIBUTION OF WEALTH IN CANADA

The only periodic data available in Canada on the asset holdings and net worth of the household sector are data collected through a series of household surveys originally initiated in 1954. Some limited data on the holdings of financial claims by the personal and unincorporated business sector are available from flow of funds work. Data are unavailable for estimation from estate tax returns.
The scope of the surveys has been expanded substantially so that the most recent survey obtained a very comprehensive list of asset holdings. The experience with Canadian surveys has been similar to that of other countries; surveys appear to underestimate asset holdings although the estimates are more reliable for widely held assets than for assets with a very skewed distribution. Nevertheless, the surveys appear to trace the accumulated distribution of personal savings over time to a considerable degree and provide useful cross-sectional trend data.
Canadian data show that wealth is more unequally distributed among family units than is income although wealth appears to be more equally distributed between income groups than is income. Wealth is also very unequally distributed within the same income group. Over time, there appears to have been some movement towards a more equal distribution of asset holdings between income groups.     

最低工资对中国工人收入及分配的影响*——基于CHNS数据的经验研究

本文运用微观调查数据,研究最低工资政策对工人收入及分配结构的影响。首先分析最低工资对工人收入水平的整体影响,然后应用倍差法和比例法分析最低工资政策对不同类型工人收入增长率的影响,以考察最低工资的收入分配效应。分析结果显示,总体而言最低工资对工人收入不具有显著影响,仅仅对部分低收入群体如女性群体有一定正面影响;对于收入水平位于上一期最低工资150%～250%区间内的工人收入,最低工资具有显著负向影响。这些显示该政策可能会对收入分配结构产生一定轻微影响。     

How large are wage differentials in Austria?

The OECD has repeatedly recommended that wage bargaining in Austria be decentralised to allow wage diferentials to widen. But the status quo itself is in question. While studies of aggregate industry data indicate a high degree of wage dispersion, research based on data from household surveys seems suggest that income inequality in Austria is as small as in the Scandinavian countries. This paper seeks to reconcile these opposing views. It shows that data from the household surveys underestimate the size of inter-industry wage differentials. An analysis of the structure of contractual wage rates supports the view that wage inequality is very pronounced in Austria and that a narrowing of the wage gap would lead both to an increase in productive efficiency and an increase in income equality.     

Industry Wages Across Countries and Over Time: A New Database of Micro Survey Data

This paper presents a newly collected database on industry wages. The underlying data are micro datasets collected through nationally representative household surveys which are mostly conducted by national statistical agencies. In comparison with wage measures based on macroeconomic data sources, we find that industry wages based on micro survey data are more reliable. Furthermore, data from nationally representative micro surveys are becoming increasingly available, thus allowing for better coverage, especially of low‐income countries. The database provides a reliable source of data for research on inter‐industry wage structures and gender wage differentials, across countries and over time. It may also serve as a basis for further research on the determinants and implications of inter‐industry and gender wage variations.     

中国居民消费需求不足原因研究——基于中国城乡分省数据

This paper uses Chinese urban and rural panel data for 30 provinces, autonomous regions and municipalities (except Tibet and Taiwan) on the consumption of Chinese urban and rural households in 1995–2005, by constructiong a random effect model, to analyze the impact of sources of household’s consumption demand on the Chinese economy. The quantitative analysis reveals that the per capita disposable income of households is highly relevant in explaining households’ per capita consumption expenditure, in these eleven years, and that China’s consumption function was fairly stable. On the basis of flow of funds accounts (barter transaction) data in 1992–2004, the paper further reveals that, since 1997–1998, China’s consumer demand remains in the doldrums because of the following distribution and redistribution process of the national income: The Government’s share of total income and disposable income is becoming ever larger, while the share of households is declining. Aside from the result that a rise in the burden of personal tuition has a negative impact on per capita consumption demand for urban households, we have not found that housing reform or medical expenses significantly reduce consumer demand in China. We believe that low household consumption demand is caused mainly by the income redistribution between households, government, and corporations rather than the inequality in income distribution across households.     

Quantitative Analysis of the COVID-19 Pandemic Shock to Household Consumption in China

We study the impact of the COVID-19 pandemic shock on household consumption in China. Using household survey data, we find that the proportion of liquidity-constrained households increases quickly, but the constraint levels vary across distinct groups. We build a heterogeneous agent life cycle incomplete market model to analyze the long-run and short-run effects of the pandemic shock. The quantitative results reveal a slow recovery of consumption due to three reasons: hiking unemployment rate, declining labor productivity, and worsening income stability. The hiking unemployment rate plays the key role in households’ consumption reduction since it simultaneously leads to a negative income effect and upsurging precautionary saving motives. Our paper highlights the importance of maintaining a stable labor market for faster recovery.     

零工经济如何改变性别工资差距*——基于家庭与市场的双重视角

中国企业生产与性别收入分配的格局正在发生深刻变化。零工就业意味着雇佣的非正式化与收入的不稳定化，女性被大量吸纳进入零工经济的同时，参与劳动力市场和家庭的方式也发生转变，性别工资差距可能随之变化。理论分析表明，在市场领域，非正式雇佣加深了劳动后备军对工资的挤压效应，女性作为劳动力“蓄水池”，收入下降效应更为明显；在家庭领域，不稳定收入加深了劳动者的自我规训，家务劳动时间分配不均使收入差距进一步扩张。在上述两种效应下，零工经济中的性别工资差距将大于非零工经济。基于微观调查数据的经验研究结果验证了上述理论推演。劳动者“灵活性”和“安全性”的综合指标表明，只有建立灵活安全的劳动力市场机制，重视弱势群体的就业保护，才能真正推动零工经济成为“稳就业、保增长”的中坚力量。     

Recent developments in China's labor market: Labor shortage,rising wages and their implications

China's abundant supply of cheap labor has played an important role in its remarkable economic and social development. Recently, however, China has experienced a labor shortage and rising wages, implying that the country's long‐lasting competitive advantage based on its “unlimited” labor supply and low costs is vanishing. We find that structural demographic changes, regional economic growth disparities and the household registration system may have caused the labor shortage. Furthermore, China's continued low wages, relatively low labor share of gross national income, declining proportion of household consumption to GDP , and productivity improvements as well as increasing unit labor costs can be used to explain the recent wage increases. The dramatic development of its labor market signals that China is entering a new stage of economic development. The country's prior successful model of economic development needs to be adjusted to adapt to the new situation in its labor market to achieve sustainable economic development.     

From internal imbalances to global imbalances: a survey on the causes of China’s export-led growth

There is a broad consensus that China’s export- and investment-led growth model is unsustainable and therefore needs to become more balanced. In the public debate, Chinese exchange rate interventions are mostly made (solely) responsible for this. But it is unclear whether and how much the Renminbi is undervalued, and if an exchange rate appreciation helps to reduce China’s current account surplus significantly. This survey reviews the international literature on China’s export-oriented growth model. Internal structural imbalances in the Chinese economy, resulting in an extremely low consumption-to-GDP share by historical and international standards, play hereby a central role. Related to this are: 1) the drop in household and wage income as a share of GDP and low employment growth, and its impact on consumption demand; 2) the increase in income uncertainty and inequality, and its impact on household savings; and 3) the role of government spending, i.e., high and increasing public surpluses. The central policy challenge is therefore to increase household incomes, and to reduce income inequality and uncertainty.     

收入结构对家庭消费倾向和消费结构的影响*——基于心理账户视角的研究

本文关注不同收入结构对家庭消费的影响，从行为经济学视角解释了近年来中国居民消费率和非工资性收入占比同时提高的现象。本文使用中国家庭跟踪调查（CFPS）数据，采用面板数据双向固定效应模型进行分析。结果显示，转移性收入和财产性收入的边际消费倾向显著高于工资性收入和经营性收入，财产性收入的边际消费倾向最高，而工资性收入和经营性收入间的边际消费倾向无统计差异。工资性收入和经营性收入更多用于居住等生活必需支出，财产性收入和转移性收入则用于提高众多子类消费。此外，以上结果在城乡间和地区间具有异质性。     

Sri Lankan households a decade after the Indian Ocean tsunami

This study estimates the causal effect of the 2004 Indian Ocean tsunami on household consumption and income in Sri Lanka 8 years after the event, using a difference‐in‐differences methodology and extensive household survey data. The analysis finds a strong association between the area‐wide tsunami disaster shock and increases in household income and consumption in the long term. The increase in consumption is much smaller than the observed increase in income; while the increase in income is mostly observed in nonagricultural wage income (and a decline in agricultural income). We also find that households in high‐income regions and lower‐damage districts experienced a much better recovery, in terms of income, than those in poorer regions or those districts that experienced more destruction. Deviating from the common observation on short‐term adverse impacts of catastrophic disasters in low‐ and middle‐income countries, these results are suggestive of a potential for long‐lasting and more successful recovery scenarios. Still, Sri Lanka received a very large amount of external assistance post‐tsunami—an amount that may not be replicable elsewhere. It is likely that this massive inflow of assistance, further helped by the end of the armed conflict in 2009, has contributed significantly to this relatively successful recovery.     

Measuring the Level and Inequality of Wealth: An Application to China

We construct and compare three distinct measures of household asset wealth that complement traditional income‐ or expenditure‐based measures of socioeconomic status. We apply these measures to longitudinal household survey data from China and demonstrate that household asset wealth has been increasing over time, a theme consistent with many previous studies on the process of development in China. Unlike other studies that have shown rising income inequality over time, however, we show that asset wealth inequality has actually been declining in recent years, indicating widespread participation in the benefits of economic reforms. Furthermore, the evolution in the cumulative distribution of household welfare is such that social welfare has been increasing with the passage of time, despite rising inequality in the early years of the survey.     

DISTRIBUTION OF LABOR INCOMES IN URBAN ZAIRE

The author addresses himself first to the problem that summary measures of wage income inequality, computed for Kinshasa, the main urban area in Zaire, tend to overstate the degree of total labor income inequality among sharing units of comparable size. It is argued that this is true for two main reasons: (1) earnings from female commercial activity are not recorded in the available statistics; and (2) the 1960 UN definition of household upon which the measures of inequality are based understates the size of the actual sharing unit. Data taken from the 1967 Socio-Demographic Survey of Kinshasa and the 1970 household budget study are used to test these hypotheses regarding short-run income inequality.
The policy observation is made that, while modernization of the commodity distribution system may provide a disincentive for sharing and a reduction in opportunities for female employment, investment in non-service sectors may equalize the secular income distribution for a given migration cohort. Evidence of unskilled migrants moving from service to non-service sector employment in response to increased labor demand is presented. This is accomplished by supplementing sample survey data with time series on aggregate employment by sector for Kinshasa.

Viewpoint: Measuring the well‐being of the poor with income or consumption: a Canadian perspective

Abstract There is a long tradition of using consumption measures derived from Statistics Canada's household expenditures surveys to study material well‐being, inequality, and poverty. We offer an introduction to this research. Income and consumption measures give different pictures of the patterns of material well‐being in Canada, but the differences are not as large as in the US. We also provide a comparison to Meyer and Sullivan's results on data quality. Canadian expenditure surveys are of high quality. Unique aspects of these surveys (variation in quality control measures over time and the possibility of comparing to income tax data) provide important insights into the quality of survey data on income and consumption.     

初次收入分配与技术进步——基于马克思主义经济学的视角

生产力概念的深化对于马克思主义的发展非常重要,考察初次收入分配与技术进步之间的关系是一个可行的切入点。在税收收入占比保持不变的情况下,劳动收入占比的下降意味着资本收入占比的上升。劳动收入占比的下降缩小了消费市场规模而抑制技术进步(消费效应),资本收入占比的提高使得企业技术投资面临更少的融资约束而促进技术进步(融资效应),初次收入分配与技术进步之间可能呈现出无关、线性或者倒U型关系,其具体关系要视消费效应和融资效应的相对强弱而定。基于中国省际面板数据的实证分析发现,中国初次收入分配与技术进步之间的关系呈现出倒U型关系,存在一个最有利于技术进步的初次收入分配格局,意味着当前需要同时保护劳动和资本的权利。     

我国劳动收入比重偏低的成因分析——基于劳动力市场的视角

近年来我国劳动收入在初次分配中的比重呈下降趋势。劳动收入比重偏低会对收入分配公平、消费投资平衡和经济增长质量产生负面影响。文章基于劳动力市场的视角对我国劳动收入比重偏低的成因进行了理论研究,并采用我国2000-2011年省级面板数据,构建了一个劳动收入比重决定模型,实证检验了经济发展过程中,二元经济转型和劳动力市场分割对我国劳动收入比重变化的影响。研究结果表明,我国劳动收入比重偏低是二元经济转型的特定发展阶段和劳动力市场分割的制约力量协同作用的结果。在二元经济转型过程中,劳动收入比重的变化趋势呈U型规律。我国劳动收入比重偏低的原因在于,劳动力市场城乡分割和劳动力市场行政垄断行业分割延缓了二元经济转型进程,增加了劳动收入比重在下降阶段的停留时间。因此,稳定我国劳动收入比重的关键是削弱劳动力市场分割,加快二元经济转型。
