The relationship between economic growth and inequality : evidence from the age of market liberalism

Using a panel data set of selected countries, this paper shows that the inequality-growth relationship follows an ordinary-U curve during the period 1970-98, in which inequality first decreases and then increases with economic growth. In addition, there is some evidence that the increasing pattern may reverse at higher levels of income. A time-series approach shows that a substantial group of countries capture a minimum turning point in different years along the period and others follow a permanent positive trend. It also indicates that only a few countries reverse inequality in a latter stage and display a maximum turning point after the mid 1990s; these countries are associated with macroeconomic stability, high governance and moderate expansion of trade and FDI. Hence, the inequality-growth relationship during the era of market openness has tended to change towards a positive one, although it might reverse at a later stage. -- Income Distribution ; Economic Growth ; Dynamic Panel Data Models ; Time-Series Analysis
