Middle class values have long been perceived as drivers of social cohesion and growth. This paper investigates the relation between class (measured by position in the income distribution), values, and political orientations using comparable values surveys for six Latin American countries. The analysis finds that both a continuous measure of income and categorical measures of income-based class are robustly associated with values. Both income and class tend to display a similar association to values and political orientations as education, although differences persist in some important dimensions. Overall, there is no strong evidence of any "middle class particularism": values appear to gradually shift with income, and middle class values are between the ones of poorer and richer classes. If any, the only peculiarity of middle class values is moderation. The analysis also finds changes in values across countries to be of much larger magnitude than the ones dictated by income, education, and individual characteristics...

Latin America is together with Sub-Saharan Africa the most unequal region of the world. This paper documents recent inequality trends in the Latin American region, going beyond traditional measures of income inequality. The paper also reviews some of the explanations that have been put forward to understand the current situation, and discusses why reducing income inequality should be an important policy priority. In particular, the authors discuss channels through which inequality can affect growth and output volatility. On the whole, the analysis suggests a two-pronged approach to reduce inequality in the region that combines policies aimed at improving the distribution of assets (especially education) with elements aimed at improving the capacity of the state to redistribute income through taxes and transfers.

Large numbers of agricultural labor moved from the countryside to cities after the economic reforms in China. Migration and remittances play an important role in transforming the structure of rural household income. This paper examines the impact of rural-to-urban migration on rural poverty and inequality in the case of Hubei province using the data of a 2002 household survey. Since remittances are a potential substitute for farm income, the paper presents counterfactual scenarios of what rural income, poverty, and inequality would have been in the absence of migration. The results show that, by providing alternatives to households with lower marginal labor productivity in agriculture, migration leads to an increase in rural income. In contrast to many studies that suggest the increasing share of non-farm income in total income widens inequality, this paper offers support for the hypothesis that migration tends to have egalitarian effects on rural income for three reasons: (i) migration is rational self-selection - farmers with higher agricultural productivities choose to remain in local agricultural production while those with higher expected return in urban non-farm sectors migrate; (ii) poorer households facing binding constraints of land shortage are more likely to migrate; and (iii) the poorest poor benefit disproportionately from remittances.

The author examines, taking into account the urban-rural divides, the changes and welfare implications of income diversification in Zimbabwe following macroeconomic policy changes and droughts of the early 1990s. Data from two comparable national income, consumption and expenditure surveys in 1990-91 and 1995-96, which straddled a period of economic volatility and natural disasters, show that the percentage of households earning income from private and informal sources grew considerably, while that from government and formal sources declined in the aftermath of the drought and policy changes. The author finds that, in general, rural households tend to have a more diversified portfolio of income compared with their urban counterparts, and the degree of diversification decreases with the level of urbanization. However, there are important differences in the level of diversification within the rural and urban areas depending on wealth: While the relatively better-off households have a more diversified income base in rural areas, it is the poor who pursue multiple income sources in urban areas. A decomposition of changes in welfare indicates that the total contribution of income diversification is large and increased between 1990-91 and 1995-96 in both urban and rural areas. On the other hand...

After decades of persistent disparities, inequality in Brazil has fallen steadily over the last fifteen years. This robust rate of decline has surpassed the pace of the Latin American region as a whole, and is taking place as inequality rises in several rapid-growth emerging economies in other regions. This document examines the recent trend in income inequality in Brazil, its key policy drivers and some of the challenges ahead. It aims at capturing some of the lessons behind Brazil?s experience to share with other economies in the region and beyond.

With the exception of Sub-Saharan Africa, Latin America and the Caribbean has been one of the regions of the world with the greatest inequality. This report explores why the region suffers from such persistent inequality, identifies how it hampers development, and suggests ways to achieve greater equity in the distribution of wealth, incomes and opportunities. The study draws on data from 20 countries based on household surveys covering 3.6 million people, and reviews extensive economic, sociological and political science studies on inequality in Latin America. To address the deep historical roots of inequality in Latin America, and the powerful contemporary economic, political and social mechanisms that sustain it, Inequality in Latin America and the Caribbean outlines four broad areas for action by governments and civil society groups to break this destructive pattern: 1) Build more open political and social institutions, that allow the poor and historically subordinate groups to gain a greater share of agency...

Inequalities in health have recently started to receive a good deal of attention in the developing world. But how large are they? An how large are the differences across countries? Recent data from a 42-country study, show large, but varying inequalities in health across countries. The author explores the reasons for these inter-country differences, and concludes that large inequalities in health, are not apparently associated with large inequalities in income, or with small shares of publicly financed health spending. But they are associated with higher per capita incomes. Evidence from trends in health inequalities - in both the developing, and the industrial world - supports the notion that health inequalities rise with rising per capita incomes. The association between health inequalities, and per capita incomes is probably due in part, to technological change going hand-in-hand with economic growth, coupled with a tendency for the better-off to assimilate new technology ahead of the poor. Since increased health inequalities...

For health outcomes, is poverty destiny? The authors explore this question for life expectancy in Africa, where health outcomes are positively correlated with income, but where the link is far from uniform. The key variables associated with good health outcomes (controlling for health expenditures) are access rates - to health services, to clean water and sanitation, and to education, particularly for women. Health expenditure, either as percentage of GNP or per capita, is not a good predictor of health outcomes (endogeneity aside). The tenuous link among health expenditures, health service outputs, and health outcomes suggests marked differences in the mapping from spending to services and from services to outcomes. While few conclusions can be drawn on the aggregate level, the patterns raise questions about what share of public expenditure should be devoted to preventive as opposed to curative measures, and the relative importance of sanitation infrastructure versus traditional health care.

When average income rises, the average incomes of the poorest fifth of society rise proportionately. This is a consequence of the strong empirical regularity that the share of income accruing to the bottom quintile does not vary systematically with average income. The authors document this empirical regularity in a sample of 92 countries spanning the past four decades and show that it holds across regions, periods, income levels, and growth rates. The authors next ask whether the factors that explain cross-country differences in the growth rates of average incomes have differential effects on the poorest fifth of society. They find that several determinants of growth--such as good rule of law, opennness to international trade, and developed financial markets--have little systematic effect on the share of income that accrues to the bottom quintile. Consequently, these factors benefit the poorest fifth of society as much as everyone else. Thee is some weak evidence that stabilization from high inflation and reductions in the overall size of government not only increase growth but also increase the income share of the poorest fifth in society. Finally...

Present levels of income inequality in Czech Republic, Estonia, Latvia, Lithuania, Hungary, Poland, Slovakia, and Slovenia remain considerably higher than their pre-transition levels, although the relative pace of change over time has varied quite a bit across countries. Using data from the 2006 European Union Survey of Income and Living Conditions, this paper finds that prevailing levels of income inequality in these countries continue to be low by international standards, and that this is in large part due to the very high redistributive impact of direct taxes and public transfers. In addition to the instrumental role of tax and transfer policies in redistributing income, the paper highlights the important role played by differences in education levels and labor market participation rates in explaining observed inequalities across people and across different regions (although not in explaining observed differences across countries). The paper includes an analysis of key factors that help explain observed variation across countries in the level of public support for redistribution...

The authors develop a microeconometric method to account for differences across distributions of household income. Going beyond the determination of earnings in labor markets, they also estimate statistical models for occupational choice and for conditional distributions of education, fertility, and nonlabor incomes. The authors import combinations of estimated parameters from these models to simulate counterfactual income distributions. This allows them to decompose differences between functionals of two income distributions (such as inequality or poverty measures) into shares because of differences in the structure of labor market returns (price effects), differences in the occupational structure, and differences in the underlying distribution of assets (endowment effects). The authors apply the method to the differences between the Brazilian income distribution and those of Mexico and the United States, and find that most of Brazil's excess income inequality is due to underlying inequalities in the distribution of two key endowments: access to education and to sources of nonlabor income...

This paper develops a method to decompose differences across distributions of household income, based on counterfactual distributions that 'lie between' the actually observed distributions. Our approach decomposes differences between any two income distributions (or functionals such as inequality or poverty measures) into shares due to price effects; occupational structure effects; and endowment effects. Comparing the household income distributions of the USA and Brazil in 1999, we find that most of Brazil's excess inequality (of 13 Gini points) is accounted for by underlying inequalities in the distributions of education and of non-labor income, notably pensions (between four and six Gini points each). Steeper returns to education in Brazil also make an important contribution (of two to five points). Differences in occupational structure and in racial and demographic composition are much less important.

This paper provides an overview of research on income inequality in China over the period of economic reform. It presents the results of two main sources of evidence on income inequality and, assisted by various decompositions, explains the reasons income inequality has increased rapidly and the Gini coefficient is now almost 0.5. This paper evaluates the degree of income inequality from the perspectives of people's subjective well-being and government concerns. It poses the following question: has income inequality peaked? It also discusses the policy implications of the analysis. The concluding comments of this paper propose a research agenda and suggest possible lessons from China's experience that may be useful for other developing countries.

Although average incomes in China have risen dramatically since the 1980s, concerns are increasing that the rural elderly have not benefited from growth to the same extent as younger people and the urban elderly. Concerns about welfare of the rural elderly combine spatial and demographic issues. Large gaps exist between conditions in coastal and interior regions and between conditions in urban and rural areas of the country. In addition to differences in income by geography, considerable differences exist across demographic groups in the level of coverage by safety nets, in the benefits received through the social welfare system, and in the risks of falling into poverty. This book aims to do two things: first, it provides detailed empirical analysis of the welfare and living conditions of the rural elderly since the early 1990s in the context of large-scale rural-to-urban migration, and second, it explores the evolution of the rural pension system in China over the past two decades and raises a number of issues on its current implementation and future directions. Although the two sections of the book are distinct in analytical terms...

In 2012, the Latin America and the Caribbean (LAC) region continued its successful drive to reduce poverty and build the middle class. The proportion of the region's 600 million people living in extreme poverty, defined in the region as life on less than $2.50 a day, was cut in half between 2003 and 2012 to 12.3 percent. Reflecting the upward mobility out of poverty, households vulnerable to falling back into poverty became the largest group in LAC in 2005, and represent almost 38 percent of the population. However, in the last two years, the share of vulnerable households has started to decline. The middle class, currently 34.3 percent of the population, is growing rapidly and is projected to replace the vulnerable as the largest economic group in LAC by 2016. The Southern Cone region (including Brazil) continued to be the most dynamic region and the main driver of poverty reduction in LAC, while poverty in Central America and Mexico proved more stubborn. About 68 percent of poverty reduction between 2003 and 2012 was driven by economic growth, with the remaining 32 percent arising from decline in inequality. Overall, equality of access to basic childhood goods and services has improved in recent years. Yet access can be further improved...

The paper presents an overview of calculations of global inequality, recently and over the long-run as well as main controversies and political and philosophical implications of the findings. It focuses in particular on the winners and losers of the most recent episode of globalization, from 1988 to 2008. It suggests that the period might have witnessed the first decline in global inequality between world citizens since the Industrial Revolution. The decline however can be sustained only if countries' mean incomes continue to converge (as they have been doing during the past ten years) and if internal (within-country) inequalities, which are already high, are kept in check. Mean-income convergence would also reduce the huge "citizenship premium" that is enjoyed today by the citizens of rich countries.

The objective of this report is to provide some policy guidelines for the fight against poverty. In particular, it hopes to be able to identify the growing sectors, as well as the constraints faced by the poor in benefiting from this growth. The report is part of a series of studies conducted within the Poverty Reduction Group (PRMPR) to foster understanding of the role of employment earnings and labor markets in shared growth. In addition, it is intended to function as a background document for the World Bank's Nicaragua Poverty Assessment 2007. The degree to which growth is able to translate into poverty reduction depends on how its benefits are distributed among different segments of society. There is little doubt that growth measured by changes in average income contributes significantly to poverty reduction. However, it is also clear that countries differ in the degree to which income growth spells have translated into poverty reduction. Although differences in the responsiveness of poverty to income growth account for a small fraction of the overall differences in poverty changes across countries...

The authors study complex interactions between gender and poverty in postwar Bosnia and Herzegovina. The goal of their analysis is to uncover how a spectrum of gender differentials at different parts of the life cycle varies across income groups. Using the data from the 2001 Bosnia and Herzegovina Living Standards Measurement Study, the authors find strong gender-poverty interaction in the patterns of labor force participation, gender gap in earnings, individuals' school finances, and school attendance. The main source of gender inequality seems to come from differences in investments in girls' and boys' educations that increase with declines in income levels. Short-term income shocks could lead to long-term increases in gender inequality in households with school age children, unless there is ready access to credit markets. The authors also find that the magnitude of the impact of economic development on gender differences in Bosnia will depend on where the growth is concentrated. If the poor capture at least some benefits of economic growth...

There is little doubt that economic growth contributes significantly to poverty reduction; however, countries clearly differ in the degree to which income growth translates into reduced levels of poverty. Although cross-country estimates suggest that differences in the responsiveness of poverty to income growth account for a small fraction of overall differences in poverty changes across countries, from the point of view of an individual country these differences may have significant implications for poverty reduction, especially in the short term. The report is structured into eight chapters, beginning with this introduction. Chapter two describes the data and the main definitions used in this report. Chapter three provides the socioeconomic context of the study, with a particular emphasis on growth, poverty, and labor market characteristics. Chapter four takes a look at the linkages between macro and microeconomic data by reviewing the ways in which changes in aggregate and sectoral labor productivity translate into individual earnings as gathered from the household surveys. Chapter five also reviews the relationships between productivity and earnings by looking at the linkages between changes in aggregate and sectoral labor productivity data (macro) and changes in individual earnings as gathered from the household surveys (micro). Chapter six examines the origins and determining factors of household earnings and employment and assesses their impact on poverty and poverty reduction. Chapter seven analyzes the individual and household characteristics that are associated with having either 'good' jobs or 'bad' jobs and reviews the question of whether there may be barriers preventing the movement of workers from bad to good labor market segments. Finally...

Internal migration plays an important role in moderating regional differences in well-being. This paper analyzes migrants' choice of destination, using Census and Living Standard Surveys data from Nepal. The paper examines how the choice of a migration destination is influenced by income differentials, distance, population density, social proximity, and amenities. The study finds population density and social proximity to have a strong significant effect: migrants move primarily to high population density areas where many people share their language and ethnic background. Better access to amenities is significant as well. Differentials in expected income and consumption expenditures across districts are found to be relatively less important in determining migration destination choice as their effects are smaller in magnitude than those of other determinants. The results of the study suggest that an improvement in amenities (such as the availability of paved roads) at the origin could slow down out-migration substantially.
