          Global Inequality and the Global Inequality Extraction Ratio ; The Story of the Past Two Centuries (English)
          Working paper by Milanovic, Branko, 2009, 29 pages
          Categories: Trade and Poverty

          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 around the 1950s, and the main determinants of global inequality have become differences in mean country incomes rather than inequalities within nations. The inequality extraction ratio (the percentage of total inequality that was extracted by global elites) has remained surprisingly stable, at around 70 percent of the maximum global Gini, during the past 100 years.

          Global Inequality: From Class to Location, from Proletarians to Migrants (English)
          Working paper by Milanovic, Branko, 2011, 25 pages
          Categories: Globalization and Development Strategies, Migration and Development

          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 its universal appeal. More than 150 years later, in the early 21st century, the situation has changed fundamentally: more than 80 percent of global income differences is due to large gaps in mean incomes between countries, and unskilled workers’ wages in rich and poor countries often differ by a factor of 10 to 1. This is the basis on which a new global political issue of migration has emerged because income differences between countries make individual gains from migration large. The key coming issue will be how to deal with this challenge while acknowledging that migration is probably the most powerful tool for reducing global poverty and inequality.
