This paper incorporates assignment frictions and sector-specific training into the Roy model of occupational choice. Assignment frictions represent the extent of the market whereas differences in sector-specific training reflect worker specialization. This framework thus captures Adam Smith’s idea that the extent of the market determines the division of labor. The paper demonstrates the way in ...

International migration is costly and initially only the middle class of the wealth distribution may have both the means and incentives to migrate, increasing inequality in the sending community. However, the migration networks formed lower the costs for future migrants, which can in turn lower inequality. This paper shows both theoretically and empirically that wealth has a nonlinear effect on...

Inequalities and Their Measurement This paper is a review of the recent advances in the measurement of inequality. Inequality can have several dimensions. Economists are mostly concerned with the income and consumption dimensions of inequality. Several inequality indices including the most widely used index of inequality namely the Gini coefficient is discussed. Non-income inequality includes i...

This paper studies the link between migration, remittances and productive assets accumulation for a panel of poor rural households in Mexico over the period 19972006. In a context of financial markets imperfections, migration may act as a substitute for imperfect credit and insurance provision (through remittances from migrants) and, thus, exert a positive effect on investment. However, it may ...

No. There has never been good evidence for a pattern of rising inequality in low-income countries and falling inequality in higher income countries. The only evidence that appears to support the Kuznets hypothesis is the cross-sectional pattern of inequality levels across countries, although the Kuznets hypothesis is an assertion about the path of inequality within countries. Numerous cross-sec...

A Review of Decomposition of Income Inequality This paper is a review of recent developments of parametric and non-parametric approaches to decompose inequality by subgroups, income sources, causal factors and other unit characteristics. Different methods of decomposing changes in poverty into growth, redistribution, poverty standard and residual components are described. In parametric approach...

Policy, Institutional Factors and Earnings Mobility This paper uses ECHP and OECD data for 14 EU countries to explore the role of labour market factors in explaining cross-national differences in the dynamic structure of earnings: in permanent inequality, transitory inequality and earnings mobility. Based on ECHP, minimum distance estimator is used to decompose earnings inequality into the perm...

Theoretical Unification in Justice and Beyond The goal of scientific work is to understand more and more by less and less. In this effort, theoretical unification plays a large part. There are two main types of theoretical unification – unification of different theories of the same field of phenomena and unification of theories of different fields of phenomena. Both types are usually a surprise...

In Esteban and Ray (1999, Inequality public allocation and development, Mimeo.) we formalize a model in which individuals lobby before the government in order to bene"t from some productivity-enhancing government action (infrastructures, direct subsidies, permissions, in short). The government honestly tries to allocate these permissions to the agents that will make the best use of them, as rev...

This paper explores how individual preferences for redistribution depend on future income prospects. In addition to estimating the impact of individuals’ socioeconomic background and of their subjective perceptions of future mobility, we employ panel data to construct dobjectiveT measures of expected gains and losses from redistribution for different categories of individuals. We find that such...
