The consequences of health shocks on households: Evidence from China

Unexpected health shocks may bring catastrophic consequences for households. This paper examines the effect of unexpected adverse health shocks on household members' physical and mental health, labor supply, household income and asset, and health behaviors in China by analyzing two nationally representative datasets and adopting a difference-in-differences method augmented with coarsened exact matching. We find that an unexpected health shock results in a discounted out-of-pocket medical expenditure of 16,943 RMB (US$ 2647) over five years for an average household, a reduction of household income per capita of 841 RMB per year (US$ 131, or 6.0% of household annual income per capita), and a loss of net household asset per capita of 13,635 RMB (US$ 2130, or 9.7% of household asset per capita). It raises the probability of an average household applying for public poverty relief allowance by 2.8 percentage points. In addition, we document a strong intra-household spillover effect of health shocks on mental health and health behaviors. A simple back-of-envelope calculation shows that the health shock induces a private cost of 34,966 RMB (US$ 5463) over 5 years for an average household, and incurs a social financial burden of 6066 RMB (US$ 948) in 5 years per household in medical reimbursement and social welfare transfers. At a national scale, the total social burden of health shocks from cardiovascular and cerebrovascular diseases amounts to 1.1 trillion RMB (US$ 172.1 billion) over 5 years.     

Patterns of poverty in South Africa

This article brings together results from two large household surveys ‐ the October Household Survey and the Income and Expenditure Survey of 1995. The analysis adopts a simple definition of income poverty which allows comparisons between households in ten deciles defined on the basis of per capita household income. The analysis compares access to resources such as housing and land, and access to basic services across these households. It then examines the economic status of women and men living in households with different incomes. The article shows consistent correlation of per capita income with other examined variables. It illustrates further how women within each decile are disad‐vantagedcomparedwith men in terms of economic status and earning.     

The determinants of income inequality in Thailand: A synthetic cohort analysis

This paper presents tests and estimates of the human capital model of income inequality using synthetic cohort data for Thailand: 1992–2011. The model focuses on four primary determinants of income inequality: mean per capita income levels, the variances in years of education, in the number of children, and in the number of earners in the household. All of these factors are important sources of income inequality in Thailand, with relative impacts that differ across demographic groups and types of household structure. An inverted-U relation between mean per capita income levels and inequality is found, reflecting gender differences of the head of household, differences in household composition, and variation in access to finance. Although the human capital model emphasizes education, estimates presented here show other household characteristics, such as number of children and number of earners, can be even more important sources of inequality.     

The Invisible Hand of Rain in Spending: Effect of Rainfall‐Driven Agricultural Income on Per Capita Expenditure in Ghana

This paper uses a nationally representative household pseudo‐panel dataset for Ghana, a rain‐fed agriculture economy, to investigate whether there is a positive relationship between rainfall‐driven agricultural income and household per capita expenditure. By using the Two Stage Least Squares Instrumental Variable (2SLS‐IV) estimator, it is found that a fall in rainfall‐driven agricultural income leads to a decrease in per capita expenditure. The results show that the gender and the locality of the household head matter in the response of per capita expenditures to rainfall‐driven agricultural income. Female‐headed and rural households are more vulnerable to rainfall‐driven agricultural income changes. The expenditure disaggregation indicates that female‐headed households significantly reduce per capita non‐food expenditure in times of rainfall‐induced agricultural income decrease whilst the response of male‐headed households focuses more on reducing per capita food and remittance expenditures.     

The aggregate gains of eliminating gender and ethnic gaps in the Malaysian labor market

We use microdata to calculate the gains of eliminating gender and ethnic labor market gaps in Malaysia for the period 2010–2017. We document significant gaps in terms of participation in the labor market and entrepreneurship, distinguishing between employers and self-employed. Female-male ratios are 64% for labor market participation, 82% for self-employment, and 32% for being employers. Across different age and ethnic groups, gender gaps in labor force participation are particularly pronounced for older workers and in entrepreneurship for Chinese workers. Our results indicate substantial income gains if gender and ethnic gaps were eliminated. Eliminating the entrepreneurship gender gaps increases income per capita by 6.54% in the long run. When we also include the employment gender gap, the long-run gains are 26.18%. The elimination of ethnic gaps could in the long run result in a smaller but still sizeable increase in income per capita of 11.5%.     

Firm agglomeration and local poverty reduction: evidence from an economy in transition

We examine the linkages between firm agglomeration and the welfare of households in Vietnam. We measured firm agglomeration by per capita firm output at the district level and household welfare by per capita income, expenditure, and poverty. We find that firm agglomeration helps households move from the informal sector to the formal sector. As a result, there is a positive effect of firm agglomeration on per capita income, per capita expenditure, and poverty reduction, albeit of a small and time‐decreasing magnitude. The effect of firm agglomeration on per capita expenditure tends to be higher for households with men, younger, and more educated heads than households with women, older, and less educated heads. Households in rural areas and those that do not have crop land are more likely to benefit from firm agglomeration than those living in urban areas and having crop land.     

Regional Income Inequality and Welfare in China: A Dominance Analysis

Inference-based dominance analysis is applied to micro data containing comprehensive measures of rural and urban incomes in seven major regions of China. Ordinal inequality rankings are estimated for Lorenz curves of household income, per capita household income and square root equivalences scale adjusted income. Regional inequality is shown to be sensitive to the treatment of household size. The lack of reliable regional cost of living measures leads us to propose that entire food expenditure share quantile distributions be used as indicators of differences in well-being within and across regions. The results indicate that statistical rankings of Lorenz dominance and food share dominance are very different indicators of regional disparities in income and welfare in China. One urban region is shown to have been in the unenviable position in 1988 of being at the bottom of the Lorenz dominance ranking and tied for last in terms of food share dominance.     

Parental Education and child Nutrition in Indonesia

This study uses 1989 Susenas household data to examine the impact of parental education on pre-school children's nutritional status, as measured by weight-for-age Z-scores. Reduced form regressions are estimated separately for boys and girls in rural and urban areas; explanatory variables include mother's and household head's education; per capita household expenditure; and aspects of the household sanitary environment. The analysis controls for influence of unobserved heterogeneity at village level, e.g. differences in prices and medical service provision. The estimates show a significant effect of parental schooling on child health status, varying between urban and rural areas, and by child gender and age. Mothers with secondary education typically have healthier boys than those with less schooling, while this effect is seen for girls only if the mother has more than secondary education. Maternal schooling significantly affects 2–5 year olds' health, but has little direct effect on that of younger children.     

A note on poverty and gender in Spain

This article focuses on the gender distribution of poverty in Spain. Our basic objective is determining if poverty is equally shared between men and women. The source of the data is the Encuesta Básica de Presupuestos Familiares 1990–1991. Having analyzed three poverty rates—the head count ratio, the income gap ratio and the normalized income gap ratio, with three poverty lines (25%, 40%, and 50% of the mean) and two income variables (OECD equivalent household income and per capita household income)—it cannot be said that the women are “over-represented” amongst the poor in Spain in 1991.     

Rural households' decisions towards income diversification: Evidence from a township in northern China

Economic reforms in rural China have brought opportunities to diversify both within-farm activities and off-farm activities. Participation in these activities plays an important role in increasing rural households' income. This paper analyzes the factors that drive rural households and individuals in their income-source diversification choices in a Northern China township. At the household level, we distinguish three types of diversification as opposed to grain production only: within-farm (non-grain production) activities, local off-farm activities, and migration. We find that land availability stimulates on-farm diversification. Local off-farm activities are mostly driven by households' asset positions and working resources, while migration decisions strongly depend on the household size and composition. At the individual level, we analyze the determinants of participation in three different types of jobs as compared to agricultural work: local off-farm employment, local self-employment and migration. We find a clear gender and age bias in access to off-farm activities that are mostly undertaken by male and by young people. The households' asset positions as well as village networks are found to strongly affect participation in off-farm activities.     

Demographic Transition in China and its Implications

The aim of this paper is to chart the demographic transition in China, identify its proximate causes and analyze its socioeconomic implications with reference to, first, the proportion and composition of the dependent population, second, the age structure of the labor force and, third, the size and composition of households. Defined as a steady deceleration in population growth to a nonrising total, the onset of the demographic transition in 1970 predates the one-child policy. Thus far the transition has had its largest impact on the proportion of children in the population, which has fallen. Next in magnitude is a rise of in the share of working-age adults. These two changes dwarf the rise in the share of the elderly on which much of the discussion in China tends to be focused. The crude dependency ratio has been falling and will continue to do so for another two decades or so. It is pointed out that the change in the age structure has significant distributive implications. The last 20 or so years have seen a substantial change the size distribution of households. The average household has shrunk in size from 4.5 in 1982 to 3.5. This is important because the distribution of the population into households has a significant impact on the household expenditure pattern. In particular, controlling for per capita expenditure, smaller households spend more on food per capita than do larger households.     

家庭资产结构与消费倾向:基于CFPS数据的研究

文章基于CFPS数据,将居民家庭资产区分为流动性较高的资产和流动性较低的资产两种类型,把不同类型资产的变现成本引入到家庭消费决策的分析中,构建了一个双资产消费决策模型,并实证研究了家庭资产结构对消费倾向的影响。整体来看,家庭流动性较高的资产占比提升有助于提高家庭的平均消费倾向,流动性较高的资产占比每增加1个百点,家庭的消费倾向增加0.11个百分点;随着家庭流动性较高的资产占比的增加,其对消费的促进作用也会显著增加。通过提高资产整体的流动性,降低金融服务费率,有助于从微观视角上扩大居民的消费需求。     

Income,Food Consumption and Estimation of Energy and Protein Intake of Households: A Study Based on the 1975 and 1980 Indonesian Social Accounting Matrices 1

This paper uses the Social Accounting Matrices for 1975 and 1980 prepared by the Central Bureau of Statistics to examine the links between household income and food consumption. The main finding is that, although the average energy and protein intake of the population was already above the minimum requirements in both 1975 and 1980, there existed some household groups which consumed less, including households which were above the assumed poverty line in terms of per capita disposable income.     

Agricultural development in Southern Africa: Theory,lessons and the food crisis in Africa

In this paper a household economics theory of farm‐household production in the Southern African context is presented which (a) places a new interpretation on the causes of low productivity per person and unit of land in the African farming sector, (b) demonstrates that even where improved food crop technology is widely adopted it may have a very limited impact on marketed production, and (c) contributes to an understanding of why Africa's food production per person continues to fall despite per capita aid inflows which have exceeded those for any other continent over the last decade.     

Fertility decline and the heights of children in Britain, 1886–1938

In this paper we argue that the fertility decline that began around 1880 had substantial positive effects on the health of children, as the quality–quantity trade-off would suggest. We use microdata from a unique survey from 1930s Britain to analyse the relationship at the household level between the standardised heights of children and the number of children in the family. Our results suggest that heights are influenced positively by family income per capita and negatively by the number of children or the degree of crowding in the household. The evidence suggests that family size affected the health of children through its influence on both nutrition and disease. Applying our results to long-term trends, we find that rising household income and falling family size contributed significantly to improving child health between 1886 and 1938. Between 1906 and 1938 these variables account for 40% of the increase in heights, and much of this effect is due to falling family size. We conclude that the fertility decline is a neglected source of the rapid improvement in health in the first half of the twentieth century.     

Non‐legal‐tender paper money: the structure and performance of Maryland's bills of credit, 1767–75

In this article, Maryland's non‐legal‐tender paper money emissions between 1765 and 1775 are reconstructed to determine quantities outstanding and redemption dates, providing a substantial correction to the literature. Over 80 per cent of this paper money's current market value was expected real asset present value and under 20 per cent was liquidity premium. It was primarily a real barter asset and not a fiat currency. The liquidity premium was positively related to the amount of paper money per capita in circulation. This paper money traded below face value due to time‐discounting, rather than depreciation. Past scholars have simply confused depreciation with time‐discounting.

Giving to the Poor? Targeting of Food Aid in Rural Ethiopia

This study determines the factors underlying the allocations of food aid in Ethiopia. We focus on regional differences in targeting criteria, and targeting accuracy according to per capita income. Data are drawn from two linked rural household surveys in 1995–96. We find large differences in food aid allocations across regions that cannot be explained by observable regional characteristics such as per capita income and rainfall. These differences are consistent with speculation that food aid is being used by the Ethiopian government to transfer resources to favored regions. We also find wide variations in the criteria used to identify recipient households across regions. We identify measurable indicators that could be used by food aid authorities to improve targeting effectiveness in the future, both across and within regions. Finally, we present simulation results on targeting accuracy under various targeting strategies and discuss potential benefits and shortcomings of those strategies.     

Re-estimating gender differences in income in South Africa: The implications of equivalence scales

Most studies of poverty and inequality in South Africa measure individual welfare by deflating total household resources, such as income, by household size. This per-capita method makes no adjustments for the different consumption needs of children or for household economies of scale. However, in addition to being more likely to live in households where average per-capita household income is lower compared with men, we show that women in South Africa also live in significantly larger households which include more children. These gendered differences in household composition are driven to a large degree by low rates of co-residency between men and women. We therefore investigate how adjusting household resources for the presence of children and economies of scale affects measures of the gender gap in income.     

新疆人均收入和收入不平等的增长与收敛——基于空间面板模型

新古典经济增长模型预测,随着时间的推移,人均收入的差距将会缩小,收入不平等将会逐渐趋同。本文利用1995年—2012年新疆15个地州的空间面板数据,采用跨部门模型和空间面板数据模型,并考虑空间交互效应来检验上述预测对新疆的正确性。研究结果显示,在对教育程度、失业、产业构成、人均收入的空间滞后增长以及区域固定效应进行调控之后,人均收入存在条件收敛,而收入不平等则存在无条件收敛。
