Outward FDI, Total Factor Productivity and Domestic Output: Evidence from Germany
Dierk Herzer 한국국제경제학회 2012 International Economic Journal Vol.26 No.1
This paper examines the impact of outward FDI on domestic output and total factor productivity by applying cointegration techniques to macroeconomic time series data for Germany. We find a positive relationship between outward FDI and domestic output as well as between outward FDI and total factor productivity. Furthermore, our results indicate that there is bidirectional causality between outward FDI and domestic output, and outward FDI and total factor productivity, suggesting that increased output and productivity are both a consequence and a cause of increased outward FDI. Overall, the results of this paper can be interpreted as evidence of productivity-enhancing, and thus growth-enhancing, effects of outward FDI, which is inconsistent with the simplistic idea that outward investment represents a diversion of domestic economic activity.
Refugee Immigration and Total Factor Productivity
Dierk Herzer 한국국제경제학회 2017 International Economic Journal Vol.31 No.3
This paper uses panel cointegration and causality techniques to examine the long-run relationship between refuge immigration and total factor productivity (TFP), a relationship that has not yet been examined in the literature. It is found that refugee immigration has, on average, a positive long-run effect on TFP, suggesting that refuge immigration increases the diversity of skills and ideas available to society as a whole, which in turn promotes specialization and innovation. It is also found that causality is unidirectional from refugee immigration to TFP, suggesting that refugees are primarily motivated by the push factor of persecution in the source country rather than by productivity (and hence welfare) gains as a potential pull factor in the destination country.
Korbinian Nagel,Dierk Herzer,PETER NUNNENKAMP 한국국제경제학회 2015 International Economic Journal Vol.29 No.4
This paper investigates the impact of foreign direct investment (FDI) on population health using panel data for up to 179 countries for the period between 1980 and 2011. Our main finding is that the relationship between FDI and health is nonlinear, depending on the level of income: FDI has a positive effect on health at low levels of income, but the effect decreases with increasing income, then changes sign and becomes increasingly negative at higher levels of income.
