I investigate how government ideology and globalization are associated with top income shares in 16 OECD countries over the period 1970 to 2010. I use the new World Top Incomes Database. Globalization is measured by the KOF index of globalization. The results show that the top 1% income share increased more under rightwing governments than under leftwing governments. The effect was stronger when globalization proceeded more rapidly.
