Using national income and expenditure distribution data from 119 countries, the authors decompose total income inequality between the individuals in the world, by continent and by region(countries grouped by income level). They use a Gini decomposition that allows for an exact breakdown (without...

Is inequality largely the result of the Industrial Revolution? Or, were pre-industrial incomes and life expectancies as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 14 ancient, pre-industrial societies using...

The effects of globalization on income distribution in rich and poor countries are a matter of controversy. While international trade theory in its most abstract formulation implies that increased trade and foreign investment should make income distribution more equal in poor countries and less...

The effect of the distribution of political rights on income inequality has been studied both theoretically and empirically. Gradstein and Milanovic review the existing literature and, in particular, the available empirical evidence. The literature suggests that formal exclusion from the...

In Latvia, only 1.5 percent of households receive social assistance, which for those households represents 20 percent of income. The allocation of social assistance is unequal. Urban households outside the capital (Riga) and those headed by male adults are systematically discriminated against....

Global inequality between world citizens, using the new PPP data (just published as part of the 2005 ICP), is estimated to be about 70 Gini points. This is some 4-5 Gini points higher than previously thought. The increases are even greater if one uses the Theil index

When income is redistributed at national level, the minimum requirement is that the transfers should be progressive, that is flow from richer to poorer individuals. The same rule should hold at the global level: it is not sufficient that transfers be from a richer to a poorer country. But...

The paper investigates the relationship between income inequality and future income growth rates of households at different points of the income distribution. The analysis uses micro-census data from U.S. states covering the period from 1960 to 2010, and controls for exposure to imports from...

We present an improved panel database of national household surveys between 1988 and 2008. In 2008, the global Gini index is around 70.5%, having declined by approximately 2 Gini points. China graduated from the bottom ranks, changing a twin-peaked global income distribution to a single-peaked...
