Contrary to previous findings, we find a systematic and economically sizeable relationship between income levels and life expectancy in a panel dataset of 197 countries over 213 years. By itself, GDP/capita explains more than 64 percent of the variation in life expectancy. The Preston curve...

This paper argues that international migration of high-skilled workers triggers productivity effects at the macro level such that the wage rate of skilled workers may rise in host countries and decline in source countries. We exploit a recent data set on international bilateral migration flows...
