Relatively little is known about the determinants of inequality in Southeast Asia. This paper fills this void by comprehensively testing Kuznets’ hypothesis for Southeast Asia. We estimate both unconditional
and conditional Kuznets’ curves using panel data for 8 countries. The analysis suggests the existence of a Kuznets’ curve with respect to per capita income; the path of inequality is nonlinear with respect to economic development. There is no evidence of a Kuznets curve with respect to non-agricultural employment. There is some evidence in terms of urbanization, though this is not robust. There is robust evidence on the role of national governments and education in shaping the path of inequality in the region. Government involvement reduces inequality. Education appears to have a non-linear effect on inequality.
