Rising income inequalities are widely debated in public and academic discourse. In this paper, we contribute to this debate by proposing a new family of measures of unfair inequality. To do so, we acknowledge that inequality is not bad per se, but that its underlying sources need to be taken...

Income mobility is often thought to equalize permanent incomes and thereby to improve social welfare. The welfare analysis of mobility often fails, however, to account for the cost of the variability of periodic incomes around permanent incomes. This paper assesses the net welfare benefit of...

We show how normative standpoints determine optimal taxation of wealth. Since wealth is not equal to capital, we find very different welfare implications of land rent-, bequest- and capital taxation. It is mainly land rents that should be taxed. We develop an overlapping generations model with...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

Income mobility is often thought to equalize permanent incomes and, thereby, to improve social welfare. The welfare analysis of mobility often fails, however, to account for the cost of the variability of periodic incomes around permanent incomes. This paper assesses the net welfare benefit of...

Using a collective model of consumption, we characterize optimal commodity taxes aimed at targeting specific individuals within the household. The main message is that distortionary indirect taxation can circumvent the agency problem of the household. Essentially, taxation should discourage less...

This study explores the extent to which inequality affects the impact of income growth on the rates of poverty changes in sub-Saharan Africa (SSA) comparatively with non-SSA, based on a global sample of 1977-2004 unbalanced panel data. For both regions and all three measures of poverty -...

This paper focuses on measuring the extent to which publicly subsidized transfers in Latin America and the Caribbean redistribute income. The redistributive power of 56 transfers in eight countries is measured by their simulated impacts on poverty and inequality, and by their distributional...

This paper analyses the relationship between growth patterns, poverty, and inequality in Brazil during its globalization process, focusing on the role played by the labour market and social programmes. Methodologically, the paper makes two contributions to the literature. One is the proposal of...
