Global Income Distribution: From the Fall of the Berlin Wall to the Great Recession

Abstract

We present an improved panel database of national household surveys between 1988 and 2008. In 2008, the global Gini index is around 70.5%, having declined by approximately 2 Gini points. China graduated from the bottom ranks, changing a twin-peaked global income distribution to a single-peaked one and creating an important global “median” class. 90% of the fastest growing country-deciles are from Asia, while almost 90% of the worst performers are from mature economies. Another “winner” was the global top 1%. Hence the global growth incidence curve has a distinct supine S shape, with gains highest around the median and top.
