This paper provides new evidence on the foreign direct investment stocks of German firms. We use firm-level data for the years 1990-2000 to describe the regional and sectoral patterns of German FDI through gravity-type equations. We provide evidence on the patterns of FDI by sector, by size of...

We derive and estimate an econometric model of export versus foreign production using firm-level data on foreign activities of German multinationals. Proximity-concentration theory which we derive our model from shows that firms face a trade-off between concentrating their production at home to...

We derive gravity equations from three different general equilibrium models incorporating multinational firms. We show that gravity equations are particularly adapted to the analysis of foreign affiliates' activities of multinational firms. However, the different theoretical models lead to...
