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...

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 and of direct foreign investment on relative income shares across the entire income distribution. It...

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...

The results of new direct price level comparisons across 146 countries in 2005 have led to large revisions of PPP (purchasing power parity) exchanges rates, particularly for China and India. The recalculation of international and global inequalities, using the new PPPs, shows that inequalities...

Using social tables, we make an estimate of global inequality (inequality among world citizens) in early 19th century. We then show that the level and composition of global inequality have changed over the last two centuries. The level has increased reaching a high plateau around 1950s, and the...

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

We present an empirical restatement of the classical economic theory of imperialism and the origins of World War I. Using recent data, we show 1) inequality was at historical highs in all the advanced belligerent countries at the turn of the century, 2) rich wealth holders invested more of their...

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...

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 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...
