This paper theoretically and empirically analyzes the interaction of emigration of highly skilled labor, an economy's income gap to potential host economies of expatriates, and optimal public infrastructure investment. In a model with endogenous education and R&D investment decisions we show...

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...

This paper analyzes the interaction between migration of high-skilled labor and publicly financed investment. We develop a theoretical model with multiple, ex ante identical jurisdictions where individuals decide on education and subsequent emigration. Migration decisions are based on...

R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth ("strong scale effect") or the level of per capita income ("weak scale effect"), with far-reaching policy implications. However, for modern times there is little empirical support...

To better understand potential relationships between income and terrorism, we study data for 1,527 subnational regions in 75 countries between 1970 and 2014. Results consistently imply an inverted U-shape that remains robust to accounting for a comprehensive set of region-level covariates,...

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...

In this paper, we provide an overview of the relationship between international migration and international trade as well as capital movements. After taking a brief historical perspective, we first investigate migration flows between two countries in a static, neoclassical context. We allow for...

This paper examines the short-run immigration effects on prices for owner-occupied housing and rents in Switzerland, exploiting regional variation at the level of 106 local labour markets ("Mobilité Spatiale" regions) and 26 cantons, respectively. We propose two empirical strategies that...
