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 analyzes the relationship between gender and corruption, controlling for country-specific heterogeneity in a panel framework. Using annual observations in a pooled setting (no country-fixed effects) confirms the positive link between the involvement of women in society and the absence...

This paper revisits the hypothesis that landlocked regions are systematically poorer than regions with ocean access, using panel data for 1,527 subnational regions in 83 nations from 1950-2014. This data structure allows us to exploit within-country-time variation only (e.g., regional variation...
