Tests of Income Pooling in Household Decisions

Using the Progresa data from Mexico, we investigate intrahousehold decision making using a variety of outcomes. We exploit both the experimental nature and the (short) panel dimension of the data to measure the impact of exogenous changes in the intrahousehold distribution of resources on household decisions. We test for global pooling of resources within households, which would correspond to the unitary model of household decision making. We also exploit a set of questions about power and the decision making process in the household to investigate aspects of strategic interactions between household members. Our findings confirm previous rejections of income pooling. We also cannot reject that the wife's relative income share is a significant determinant of the wife's decision making power in the household, with a higher share of income associated with more decision making power.

Household willingness to pay and income pooling: A comment

We demonstrate some problems with Munro 2005 (“Household willingness to pay equals individual willingness to pay if and only if the household income pools”, Economics Letters 88, 227-230). Furthermore, we reconsider income pooling in a slightly changed framework and prove: Income pooling implies that household willingness to pay is equal to minimal individual willingness to pay. The converse is not true.     

我国基本养老保险扩面的收入分配效应研究

文章基于一般均衡分析框架,通过构建“统账结合”制基本养老保险的异质性跨期交叠一般均衡动态模型,引入国发〔2005〕38号文的主要内容,利用政策仿真、参数估值和敏感性检验等方法,重点研究了养老保险制度覆盖面扩展的收入分配和再分配效应,并进行了理论推导和实证测算。结果发现：（1）我国基本养老保险扩面具有明显的收入分配和再分配效应,且再分配效应是累进的,发生了从城镇企业职工为代表的高收入者向以灵活就业人员和农民工为代表的低收入者的收入转移;（2）个人账户发挥了平滑作用,有利于改善不同类型劳动者终生的收入分配,但不利于收入再分配的改善;（3）社会统筹账户具有较强的收入再分配效应,有利于改善不同类型劳动者的收入再分配,缩小收入差距。参数敏感性检验表明结论是稳健的。因此,进一步优化社会统筹账户有利于减小收入不平等。     

Economic decision-making by cohabitors: findings regarding income pooling

Cohabitation rates are increasing in the US but little is known about how cohabitors make economic decisions. For instance, do female cohabitors treat their male partner's income as shared household income when choosing hours worked? Does income sharing differ among types of cohabitors? This study investigates whether or not cohabitors pool income by drawing inferences from a generalized model of labour supply. The empirical work uses data from the 1993 Current Population Survey and the 1987 National Survey of Families and Households. These data sets provide evidence that cohabitors, taken as a group, do not pool all income. However, there is also evidence that cohabitors are not homogeneous in their behaviour; income pooling is not rejected for cohabitors in longer-term relationships and for those who have a biological child together.     

迁移类型、户籍身份与工资收入水平*

本文基于2013年中国居民收入调查数据（CHIP）,考察各类迁移对工资收入水平的影响。OLS及PSM估计结果均表明各类迁移有利于工资收入水平的提升;采用局部工具变量法进行稳健性检验,发现本文的研究结论依然成立。分迁移范围来看,市外迁移的平均收入增长效应大于市内迁移的平均收入增长效应;分户籍类型来看,农村户籍迁移的平均收入增长效应大于城市户籍的平均收入增长效应。综合比较各种迁移类型的收入增长效应,由强至弱可以将其排列为：永久移民市外迁移、农村户籍市外迁移、本地居民市外迁移、城市户籍市外迁移、农村户籍市内迁移、城市户籍市内迁移、本地居民市内迁移、永久移民市内迁移。城市化的核心在于满足居民的自由迁移意愿,从本文的研究结论来看,鼓励就近城市化而妨碍人口跨区域流动的城市化模式尚未得到收入增长激励的支撑。在推动户籍制度改革及公共服务均等化的同时,应注重建立全国统一的要素市场,进一步完善城市的空间结构体系。     

Testing exact aggregation in income and household characteristics: the effects of aggregation across goods

Exact aggregation in income and household characteristics are tested using Canadian cross-sectional microdata. Over 100 data sets of homogeneous households are used, making it possible to conduct a large number of independent hypothesis tests. Tests are also conducted to determine whether the homogeneous household groups can be grouped into more heterogeneous data sets. Six different kinds of demand systems are estimated to ensure the robustness of the results to separability/aggregation structure.Exact aggregation in income, family size, region of residence and housing tenure status are strongly rejected, but exact aggregation in age of head of household is not. Restrictions which would allow pooling of households of different sizes, regions and tenure status are also strongly rejected. The test results exhibit a little sensitivity to the expenditure aggregates used, but not to the extent that the results would be different.The results imply that aggregate demand functions which use time series data should include many statistics from the joint distribution of income and household characteristics. In addition, when using data at the micro-level, the amount of heterogeneity in households' behaviour is much greater than usually assumed. This calls for the use of much more homogeneous household groups in the estimation of demand models than are typically employed.     

The income–pollution relationship and the role of income distribution: An analysis of Swedish household data

The main purpose of this study is to analyze the relationship between pollution and income at household level. The study is motivated by the recent literature emphasizing the importance of income distribution for the aggregate relation between pollution and income. The main findings from previous studies are that if the individual pollution–income relationship is non-linear, then aggregate pollution for, say, a whole country, will depend not only on average income, but also on how income is distributed. To achieve our objective we formulate a model for determining the choice of consumption of goods in different types of household. Furthermore we link the demand model to emission functions for various goods. The theoretical analysis shows that without imposing very restrictive assumptions on preferences and the emission functions, it is not possible to determine a priori the slope or the curvature of the pollution–income relation. The empirical analysis shows that, given the model used, the pollution–income relation has a positive slope in Sweden and is strictly concave for all three pollutants under study (CO₂, SO₂, NO_x), at least in the neighbourhood of the observed income for an average household. We also show that altering the prevailing income distribution, holding average income constant, will affect aggregate emissions in the sense that an equalization of incomes will give rise to an increase in emissions. One implication is then that the development of aggregate pollution due to growth depends not only on the income level, but also on how growth is distributed.     

SOCIO-ECONOMIC ACCOUNTS FOR THE NETHERLANDS

In this paper the authors present Socio-economic Accounts for the Netherlands for the year 1981. Detailed information on income components, consumption components and savings for 52 household types are provided. The household types are a cross-classification of household size, income source and income level. For each income and consumption component, the sum of the amounts over the houshold types and three intermediary funds equals the macro amount in the National Accounts. The accounts are constructed by intregating macrodata from the National Accounts and microdata from the Income Statistics and the Budget Survey.     

中国农户的收入风险应对机制与消费波动:来自陕西的经验证据

在正规风险应对机制缺失的背景下,中国农户很大程度上依靠社会网络内的风险统筹和跨时期消费平滑等自发机制来应对收入风险,缓解消费波动。本文运用logistic回归方法,对来自陕西1 151户农户的问卷调查数据进行了计量分析,检验了两类风险应对机制对消费波动的影响。经验分析结果表明:在农户缓解收入风险所带来的消费波动的过程中,社会网络内的风险统筹仍然发挥着较大的作用;跨时期消费平滑机制也发挥着重要作用,但从内部结构来看,通过储蓄实现的自我保险的作用最为重要,信贷市场借款的作用较为有限。

Results suggest that several variables affect household expenditures on various prepared food products. Factors examined are presence of children, number of earners, region, household size, seasonality, age, race, education, and income.     

健康变化对劳动供给和收入影响的实证分析

本文使用中国健康与营养调查(CHNS)数据检验了居民健康状况变化对居民劳动供给和家庭收入的影响。通过控制基期健康状况和一系列个人特征,本文重点检验了可以被视作外生冲击的健康变化对居民劳动供给和家庭收入的影响。考虑到城乡居民以及性别在劳动供给以及收入上的差异,本文还分别分城乡和性别进行了回归分析。研究发现,滞后期健康状况与当期劳动供给和家庭收入显著正相关;健康恶化显著降低劳动供给和家庭收入。此外,健康与劳动供给和家庭收入之间的关系在城乡居民和性别之间均存在差异,具体地,城市居民和男性更容易因健康恶化退出劳动供给,农村居民和女性则会因健康改善增加劳动供给。这表明在评估健康干预政策时要综合考虑健康变化对公民社会经济状况(SES)可能造成的影响,同时,对城市居民和农村居民以及对男性和女性要区别考虑。

TYPES OF INCOME AND INEQUALITY IN CHINA AT THE END OF THE 1980s

Using a nationwide household income survey, different types of income in the People's Republic of China at the end of the 1980s is analysed. The results show that various income types play quite different roles in rural and urban areas. Subsistence income makes up about half of the total income in rural China. Money income makes up about two-thirds of total income in urban China and is the major contributor to inequality in the entire country. In kind income, of which highly subsidized housing is the single most important category, is highly concentrated in urban areas and contributes greatly to inequality.     

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.     

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.     

Household Debt,Consumption, and Income Inequality

Using the Johansen and Engle–Granger cointegration tests, we show that there is one cointegrating relationship between household debt, consumption, and income inequality in the United States for the period from 1929 to 2009. Given this result, we use a Vector Error-Correction model to further understand the dynamics among the three variables. Results indicate that increases in income inequality and consumption directly contribute to increases in household debt. Interestingly, the results reveal some feedback from household debt to income inequality. We also show that debt-driven consumption should be viewed with caution as the results show that increases in household debt correspond with future declines in the rate of consumption.     

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.     

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。

The effect of transfers on household expenditure patterns and poverty in South Africa

This paper uses household level unit record data from South Africa to examine the behavioural and welfare impacts of private and public transfers. We allow for joint endogeneity of resource variables and the expenditure shares. Our results show that crowding out of private transfers as a result of the introduction of public pensions holds only for poor households and not for the non-poor. Both private transfers and public pensions significantly reduce poverty but private transfers have a larger impact on expenditure patterns. The results also reject the hypothesis of income pooling underlying the conventional unitary model by finding that the marginal impact on expenditures are different for public pension received, private transfer received and other resources flowing into the household. The principal conclusions are robust to changes in specification.
