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...

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

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 databases of wage inequality that have become...

Inequality in world income is very high, according to household surveys, more because of differences between mean country incomes than because of inequality within countries. World inequality increased between 1988 and 1993, driven by slower growth in rural per capita incomes in populous Asian...

The median voter hypothesis plays an important role in endogenous growth theories. It provides the political mechanism through which voters in more unequal countries redistribute a larger proportion of income and thus, it is argued, by blunting incentives reduce country's growth rate. However,...

In Asia inequality in income between countries is more important than inequality within countries. In Africa, Latin America, and Western Europe and North America, by contrast, there are only small differences between countries; inequality within countries is more important. And when countries...

Ideology, as proxied by a country's dominant religion, seems to be related to inequality. In Judeo-Christian societies increased democratization appears to lead to lower inequality; in Muslim and Confucian societies it has an insignificant effect. One reason for this difference may be that...

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. They,...

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...
