This paper provides first evidence on the social returns to education from both firm-level and regional human capital. Using panel data from German social security, both at an individual and aggregated at the plant and regional level, I estimate earnings functions incorporating measures of...

Reliable information on the characteristics of exporting and non-exporting firms is important to guide theorists and policy makers in an evidence based way. This holds true especially for Germany, a leading actor on the world markets for goods and services. This paper makes three contributions...

An emerging literature on international activities of heterogeneous firms documents that exporting firms are more productive than firms that only sell on the national market. This positive exporter productivity premium shows up in a large number of empirical studies after controlling for...

This paper aims at examining the role played by inward Foreign Direct Investments (FDI) in affecting the exit probabilities of German manufacturing firms in the precrisis year 2007. We introduce two main novelties: in the first place, we include the FDI variable, dividing it between types of...

This paper summarizes in a non-technical way what we know from empirical studies based on firm-level data about the mutual links between international activities of firms and productivity. It is written with a view to inform policy makers in an evidencebased way. A special focus is on the...

Agro-biodiversity can provide natural insurance to risk-averse farmers by reducing the variance of crop yield, and to society at large by reducing the uncertainty in the provision of public-good ecosystem services such as e.g. CO2 storage. We analyze the choice of agro-biodiversity by...
