The standard formulae used to calculate poverty gaps are incorrect when the poverty analysis is conducted in terms of equivalent units (rather than in per capita terms). An exact calculation requires access to individual level data. If this is unavailable, the paper proposes an approximation.

New data derived directly from household surveys are used to examine the effects of globalization on income distribution in poor and rich countries. The article looks at the impact of openness (proxied by the ratio of trade to gdp) and of direct foreign investment on relative income shares...

The relationship between the distribution of political rights and that of economic resources has been studied both theoretically and empirically. This paper reviews the existing literature and, in particular, the available empirical evidence.Our reading of the literature suggests that formal...

While standard political economy theories suggest a moderating effect of democratization on income inequality, empirical literature has failed to uncover any such robust relationship. Here we take yet another look at this issue arguing first, that prevailing ideology may be an important...

The objective of the paper is to answer an often-asked question : if tariff rates are reduced, what will happen to wage inequality ? We consider two types of wage inequality : between occupations (skills premium), and between industries. We use two large data bases of wage inequality that have...

We are used to thinking about inequality within countries--about rich Americans versus poor Americans, for instance. But what about inequality between all citizens of the world? <i>Worlds Apart</i> addresses just how to measure global inequality among individuals, and shows that inequality is shaped by...

Was the Euro-Mediterranean region at the time of the Roman empire and its Western successor states, more unequal than the European Union is today? We use some scant evidence on personal income distribution within the Empire and differences in average regional incomes to conclude that the Empire...

Thomas Piketty's "Capital in the 21st century" may be one of the most important recent economics books. It jointly treats theory of growth, functional distribution of income, and interpersonal income inequality. It envisages a future of relatively slow growth with the rising share of capital...

Suppose that all people in the world are allocated only two characteristics over which they have (almost) no control: country of residence and income distribution within that country. Assume further that there is no migration. We show that more than one-half of variability in income of world...
