Income mobility in a high-inequality society: Evidence from the first two waves of the National Income Dynamics Study

The study of income inequality and income mobility has been central to understanding post-apartheid South Africa's development. This paper uses the first two waves of the National Income Dynamics Study to analyse income mobility using longitudinal data, and is the first to do so at a nationally representative level. We investigate both the correlates and root causes of moving up and down the income distribution over time. Using both absolute and relative changes as reference points, we highlight some of the factors associated with South Africans moving into and out of poverty.     

Analysing post-apartheid poverty trends by geo-type, 1997–2012: The understated role of urbanisation and social grants

This article investigates poverty trends in post-apartheid South Africa with an explicit focus on differences between rural and urban areas. Using nationally representative household survey data from 1997–2012, I first describe changes in population characteristics and household access to different income sources and services, by urban–rural geo-type. Income data are then used to generate poverty statistics, which cast light on divergent trends in rural and urban areas. Next, I employ a poverty decomposition method to further explore some potential reasons why the poverty trends in rural and urban areas have differed. Data from the Afrobarometer are then used to probe how subjective non-monetary welfare has changed over time across geo-types. The evidence from all surveys suggests that the dramatic increase in access to services and social grants in rural areas has played a vital role in poverty reduction.     

Is there income mobility in the Philippines?

Despite a more robust economic performance over the past decade compared with the 1980s and 1990s, growth in average household income is still far below what might be expected given the pace of economic expansion in the Philippines. Inequality of household income has also remained high, which leads to the question: is there income mobility in the Philippines? Using longitudinal data from three years of the redesigned Philippine Family Income and Expenditure Survey (2003, 2006, and 2009) and a variety of analytical tools, we examine the mobility of Filipino household income and show that it is less stagnant than is conventionally perceived. Empirical evidence suggests that significant positive and negative mobility exists; albeit, the two tend to offset each other, contributing to slow household income growth at the aggregate level. In addition, there is some evidence that transitory fluctuations contribute significantly to the observed level of income mobility. Overall, the findings are robust across different analytical tools used in measuring income mobility.     

The long-term evolution of national income inequality and rural poverty in China

Using the five waves of the China Household Income Project surveys conducted during 1988–2013, we investigate long-term changes in national income inequality and rural poverty in China. National income inequality rose markedly to 2007 and thereafter fell slightly. Income growth was widely shared, but inequality increased because the high-income percentiles had faster income growth than lower percentiles and because the gap between urban and rural household incomes widened. The fall in income inequality after 2007 reflects faster income growth among low-income percentiles and the impacts of newly introduced redistributive policies. The paper also finds a considerable, ongoing poverty reduction in rural China. A poverty decomposition analysis indicates that this rural poverty reduction was mostly due to income growth rather than redistribution.     

Microeconomic determinants of spatial mobility in post-apartheid South Africa: Longitudinal evidence from the National Income Dynamics Study

Migration, important for many areas in development, is strongly related to employment. Debate over labour supply in developing countries frequently hinges on labour migration. This paper examines the determinants of spatial mobility of working-age adults in South Africa, using the first nationally representative longitudinal survey – the National Income Dynamics Study – for 2008–10. The paper outlines the unique advantages of these data for the study of individual mobility – data that open the possibility of a new research project. Specifically, it asks how policy-relevant programmes, such as social transfers and housing assistance, affect migration. This paper finds, on balance, that transfers are negatively correlated with subsequent relocation. Previous migration is also predictive of future migration and both are tightly related to attrition, while there is an increasing but strongly non-linear relationship between income and mobility. Further, we highlight potential pitfalls – including attrition, and definitional difficulties – in the study of migration and illustrate possible solutions.     

Decomposing inequality and poverty in post-war Rwanda: The roles of gender,education, wealth and location

This paper provides an overview of poverty and inequality in post-war Rwanda. Rwanda is one of the poorest countries in the world, and has recently become one of the most unequal. High levels of poverty and inequality have important implications not only in terms of evaluations of social welfare, but also for management of social tensions and the propensity for violent conflict in the future. This paper uses the first two available and nationally representative rounds of household surveys –EICV1 2000 and EICV2 2005 – to decompose and identify the major ‘sources' of poverty and inequality in the country. I find stark differences in vulnerability to poverty by region, gender and widow status of the head of household. I additionally find important changes in the ‘income generating functions' of Rwandan households, and that distribution of land and financial assets are increasingly important in determining the inter-household distribution of income.     

The poverty of solidarity: the size and structure of informal income smoothing among worker households in Helsinki, 1928

Abstract

Informal income smoothing by households before the post-Second World War expansion in public welfare has gained attention in the history of poverty and social insurance. Little direct empirical evidence has been available. Finnish household budgets from 1928 with intra-year panel data on informal transactions enable analysis of the use of savings, loans and informal assistance to counter income variation by worker families in Helsinki. Income shares of transfers were small compared with labour-based methods of supplementing the earnings of the surveyed male breadwinner families. Within the year, however, the combined use of assistance, credit, and savings accounts compensated on average 36% of income fluctuations, while means such as added workers or taking in lodgers appeared ineffective on the short run. Informal assistance mattered for the poorest households, but provided inferior coverage compared with that attained through credit and savings by more affluent workers. Income inequality was therefore replicated as risk-management inequality.     

Towards a better measure of income inequality in Indonesia

Indonesia has experienced significant economic growth in recent years (on average, 5% in 2000–08), but many people are still living in poverty. Income inequality, as measured by the official Gini coefficient, has also increased. This paper evaluates household income and income inequality in Indonesia, assessing both market and non-market income to reach a more accurate measure of how actual income affects living standards. We find that if household income considers non-market income, income distribution is significantly more balanced, the coefficient of income inequality falls from 0.41 to 0.21 and the income share of the population's poorest deciles increases more than fivefold. The results suggest that market income alone is a misleading measure of income distribution in Indonesia.     

Nonlinear income variance profiles and consumption inequality over the life cycle

In contrast to many other countries, consumption inequalities in Japan are not constant over household age but increase from around middle age—a fact first highlighted by Ohtake and Saito [Ohtake, F., Saito, M., 1998. Population aging and consumption inequality in Japan. Rev. Income Wealth 44, 361–381]. Given this information, we examine whether this phenomenon is consistent with the standard precautionary saving model developed by Carroll [Carroll, C.D., 1997. Buffer-stock savings and the life cycle/permanent income hypothesis. Quart. J. Econ. 62, 1–56]. Specifically, we investigate: (1) the degree of age dependence of idiosyncratic income risks; and (2) the importance of age dependence for the evolution of inequalities in consumption predicted by the household model of Carroll (1997). We find a strong age dependence of income risks, which creates a nonlinear age–variance profile of income, and the standard precautionary saving model is consistent with the observed consumption inequalities as long as we take the nonlinearity in age–variance profiles of income into account.     

The scope and extent of home-based business income relative to employment earnings in financing household expenditures: a study undertaken in a subeconomic housing area within the Cape Metropole

This study was undertaken to examine the scope of home-based businesses in poor neighbourhoods and the extent to which household income is derived from them. The aim was to determine the ratio of home-based business income to wage earnings, in order to understand its relative importance in augmenting primary employment (wage-based) income. The size, necessity and importance of self-generated (business-derived) income in augmenting primary income was measured in a selected subeconomic housing area within the Cape Metropole. The significance of this analytical research is the determination of income data and the levels of poverty. This paper provides the primary data (base information) for policy formulation relating to social and economic development in this subeconomic area. The findings add to the debate for the provision of a Basic Income Allowance (grant) for those people experiencing poverty. The results correlate with findings of national longitudinal studies. The level of job creation through businesses is minimal and the extent of unemployment is much greater than anticipated.     

Understanding urban poverty in two high-density suburbs of Harare,Zimbabwe

ABSTRACT

Urban communities are heterogeneous and averages mask inequities and deprivations among poor and rich urban communities. This article examines the situation of households residing in two low-income, high-density suburbs of Harare, Zimbabwe. The aim of the research was to contextualise urban poverty by looking at selected urban communities and vertically analysing the patterns and determinants of poverty. A household survey was administered to 1000 households and qualitative data were collected through focus group discussions and key informant interviews. The study found high levels of income poverty and also found differences in poverty experiences between the two suburbs. The major proximate determinants of poverty were large family size; low education level of the household head; lack of income from permanent employment; low cash transfers; and short length of residence in the suburb. Increasing household income consumption can be addressed through scaling-up industries, which would result in more quality employment.     

Assessing black progress: employment,occupation, earnings,income, poverty

Farley discusses changes in employment, occupation, earnings, income, and poverty among US blacks. Among black men, there has been a persistent rise in unemployment since 1960. By the early 1980s, 1 black man out of 8 had dropped out of the labor force, compared to 1 in 20 white men. Some contend that many black men lack the skills to be employed or have personal habits and criminal records which make them unacceptable to employers. Others believe that the expansion of federal welfare programs offers attractive alternatives to men who have limited earnings potential. Still others stress that blacks are concentrated within cities, while the growth of employment is occurring in suburbs. Among those blacks over age 54, labor force participation has declined because of improved Social Security benefits, better private pensions, and the greater availability of Supplemental Security Income. The employment of young blacks compared to whites has deteriorated since 1960. For both races, there has been a steady rise in the employment of women. The recent increases, however, have been great for whites. By the early 1980s, white women caught up with black women in terms of employment. Unlike the indicators of employment itself, there is unambiguous evidence that the occupational distribution of employed blacks has been upgraded and is gradually becoming similar to that of whites. Findings from many studies show that blacks once earned much less than similar whites, but this racial difference has declined among men and has nearly disappeared among women. The proportion of blacks impoverished fell sharply in the 1960s, reaching a minimum of 30% in the early 1970s. Since the early 1970s, blacks have made few gains. The proportion impoverished actually increased and the ratio of black-to-white family income declined. The fact that the earnings of black males are no longer rising faster than those of whites and that there is no longer a migration from southern farms to cities plays a role, but changes in family structure are also important. At all dates, poverty rates have been high and income levels low in families headed by women. In 1984, for example, 52% of the black families with a woman as head of household were below the poverty line, compared to 15% of the black married-couple families. While similar trends are occurring in white families, there has been a sharper increase in the proportion of blacks living in these female-maintained families which have high poverty rates.     

以家庭为单位征收个人所得税的制度设计问题--基于三种所得税征收模式的讨论

1993年确立的我国现行个人所得税征收模式,随着经济形势的发展变化,虽然做过数次局部调整,从整体来看与经济发展的匹配度仍然不高。学界对我国个人所得税制度的改革主要持两种观点,一种认为应该坚持并完善现行成熟的分类所得税制,通过征管手段的提高,强化源泉课税,减少税收流失。另一种观点则主张放弃现行的分类所得税制,选择实行综合所得税制。本文主要对以家庭为单位征收个人所得税,是以分类所得税制、综合所得税制,还是混合所得税制为基础更适应现实国情的问题展开分析,在此基础上提出了混合所得税制之下实行以家庭为单位征收个人所得税的制度假设。     

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.

POST‐TRANSITION POVERTY TRENDS BASED ON AN ALTERNATIVE DATA SOURCE1

This paper analyses a previously unused source of data – the All Media and Product Survey (AMPS) – to arrive at alternative estimates of the post‐transition poverty path. The motivations for using this non‐official data source are twofold: concern over the comparability of the existing official post‐transition datasets – the Income and Expenditure Survey (IES) and Population Census – and a desire to extend analysis of poverty trends beyond 2001. While official data sources are generally preferred for purposes of poverty analysis, the IES and Census collect data at long (5 or 10 year) intervals, and additional years pass before these datasets become available to the public. In some cases there is also concern about data comparability between surveys. The expenditure data contained in the General Household Survey are available annually, although data are captured in a small number of categories that are not very conducive to analysis at the lower end of the income distribution. Analysis on AMPS data confirms the large decline in poverty implied by an increase of R18 billion (in 2000 Rand) in social grant payments between 2000 and 2004. The direction of this trend is consistent with recent research findings based on more frequently analysed data sources, including the work done by Agüero, Carter and May (2005), Seekings (2006 ) and Meth (2006 ).     

Gendered trends in poverty in the post-apartheid period, 1997–2006

This study investigates whether trends in the extent and depth of poverty in South Africa over the past decade have been gendered. We examine whether females are more likely to live in poor households than males and whether this has changed over time, and how poverty has changed for female-headed and male-headed households. We use data from the 1997 and 1999 October Household Surveys and the 2004 and 2006 General Household Surveys, which have the advantage of collecting information on the individual receipt of social grant income. We find that although poverty rates have fallen for both males and females, and for male-headed and female-headed households, the decline has been larger for males and for male-headed households. Gender differences in poverty rates have therefore widened over the period. We show that these findings are robust to the possible underestimation of household income and to adjustments for household composition.     

Income versus Consumption Inequality in Korea: Evaluating Stochastic Dominance Rankings by Various Household Attributes

Using four rounds (1999, 2002, 2005 and 2008) of the Korean Labor and Income Panel Study, the present paper examines determinants of household income and consumption levels and inequalities. Unconditional as well as conditional stochastic dominance tests are performed by year, by household heads’ characteristics (age, education, gender, health, marital status and occupation) and by household characteristics (household type, household size and degree of urbanization). Mean least squares regression techniques are used to predict conditional expectations. The residuals containing effects for each characteristic conditional on the remaining characteristics are then used for the stochastic dominance analysis employing extended Kolmogorov–Smirnov tests of first‐order and second‐order dominance in distribution of income and consumption. The results provide a detailed and up‐to‐date picture of inequality and poverty by subgroup in Korea, which helps in targeting particularly vulnerable groups. While inequality in disposable income is found to be substantial, consumption inequality is less substantial. Households headed by the elderly, the uneducated, the divorced, the widowed, females, and those with health problems are found to be the most vulnerable groups.
