The US has exceptionally high inequality of disposable household income (i.e., income after accounting for taxes and transfers). Among working-age households (those with no persons over age 60), that high level of inequality is caused by a high level of market income inequality (i.e., income...

The paper discusses recent world income inequality calculations by Sala- i-Martin. It shows that the two main problems with which the author had to grapple (too few data to derive countries’ income distributions, and sparseness of such data in time) are not solved in a satisfactory fashion....

The median voter hypothesis has been central to an extensive literature on consequences of income distribution. For example, it has been proposed that greater inequality is associated with lower growth, because of the greater redistribution that is sought by the median voter when income...

Using social tables, the author makes an estimate of global inequality (inequality among world citizens) in the early 19th century. The analysis shows that the level and composition of global inequality have changed over the past two centuries. The level has increased, reaching a high plateau...

The results of new direct price level comparisons across 148 countries in 2005 have led to large revisions of purchasing power parity exchanges rates, particularly for China and India. The recalculation of international and global inequalities, using the new purchasing power parity rates, shows...

Inequality between world citizens in mid-19th century was such that at least a half of it could be explained by income differences between workers and capital-owners in individual countries. Real income of workers in most countries was similar and low. This was the basis on which Marxism built...

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...

This paper extends the Inequality Possibility Frontier approach in two methodological directions. It allows the social minimum to increase with the average income of a society, and it derives all the Inequality Possibility Frontier statistics for two other inequality measures besides the Gini....

The paper presents a newly compiled and improved database of national household surveys between 1988 and 2008. In 2008, the global Gini index is around 70.5 percent having declined by approximately 2 Gini points over this twenty year period. When it is adjusted for the likely under-reporting of...
