Human capital and income inequality: Some facts and some puzzles
Amparo Castelló-Climent, Rafael Doménech 23 April 2014
Most developing countries have made a great effort to eradicate illiteracy. As a result, the inequality in the distribution of education has been reduced by more than half from 1950 to 2010. However, inequality in the distribution of income has hardly changed. This column presents evidence from a new dataset on human capital inequality. The authors find that increasing returns to education, globalisation, and skill-biased technological change can explain why the fall in human capital inequality has not been sufficient to reduce income inequality.
The rise of income inequality in many countries from 1985 onwards, and particularly during the recent crisis, has prompted a current debate on the causes and consequences of higher inequality and its effects on future growth (see, for example, OECD 2011, IMF 2014, or Ostry et al. 2014). As a result, and despite the slight reduction from 1960 to 1985, the average income Gini coefficient for developing countries was almost the same in 1960 (0.42) as it was in 2005 (0.41).
