Over the past 20 years, aggregate measures of global inequality have changed little even if significant structural changes have been observed. High growth rates of China and India lifted millions out of poverty, while the stagnation in many African countries caused them to fall behind. Using the...

Using for the first time household survey data from 26 post-Communist countries, covering the period 1990-2005, this paper examines correlates of unprecedented increases in inequality registered by most of the economies. The analysis shows, after controlling for country fixed effects and type of...

The present study uses the GIDD, a CGE-microsimulation model for Global Income Distribution Dynamics, to understand the ex-ante dynamics of global income distribution. Three main robust results emerge. First, under a set of realistic assumptions, there will be a reduction in global income...

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

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 paper presents a nontechnical summary of the current state of debate on the measurement and implications of global inequality (inequality between citizens of the world). It discusses the relationship between globalization and global inequality. And it shows why global inequality matters and...

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...

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...
