Almost all social transfers are conducted within nations. Is there a case for cross border transfers? What could be the grounds for such transfers from the globally rich to globally poor people? The paper explores three possible grounds: compensation for the past wrongs; economic and political...

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...

We develop and implement a method for measuring the frequency of changes in power among distinct leaders and ideologically distinct parties that is comparable across political systems. We find that more frequent alternation in power is associated with the emergence of better governance in...

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...

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...

Suppose that all people in the world are allocated only two characteristics: country where they live and social class within that country. Assume further that there is no migration. We show that 90 percent of variability in people’s global income position (percentile in world income...

Using for the first time survey data from 26 post-Communist countries, covering the period 1990-2005, the paper examines correlates of unprecedented increases in inequality registered by most of these economies. We find that, after controlling for country-fixed effects and type of survey used,...

The paper uses the data from Francois Quesnay's writings to derive a social table for pre-revolutionary France, estimate country's mean income and income distribution. These Quesnay-based estimates are compared with more recent estimates of 18th century French incomes and inequality.

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...

Using household surveys from Yemen and Djibouti, the paper analyzes determinants of qat consumptions in two countries. The results confirm huge importance of qat in daily life: with between one-half (in Djibouti) and 70 percent (in Yemen) of all households reporting at least one user. But in...
