Using meta-analytical techniques, we focus on 11 studies that explicitly measure the effect of a net migration variable in neoclassical convergence models and derive 57 comparable effect sizes. The data suggest that an increase in the net migration rate of one percentage point increases on...

Die Analyse der Patentanmeldungen deutscher Unternehmen am Europäischen Patentamt zeigt: Die Unternehmen lenken ihre Forschungsaktivitäten im Ausland vor allem in die Hochtechnologiebereiche, in denen sie seit langem besonders intensiv forschen. Dies sind die Elektrotechnik, Steuerungstechnik,...

We compare a set of econometric studies that measure the effect of net internal migration in neoclassical models of long-run real income convergence and derive 67 comparable effect sizes. The precision-weighted estimate of beta convergence is about 2.7%. An increase in the net migration rate of...

We examine environmental factors as potential determinants of international migration. We distinguish between unexpected short-run factors, captured by natural disasters, as well as long-run climate change and climate variability. Building on a simple neo-classical model we use a panel dataset...
