Services sectors' agglomeration in the European Union, its development over time, its driving factors and dynamic tendencies will be empirically investigated in this study. Locational gini coefficients are computed taking EU-KLEMS data for 14 European countries covering 22 services sectors over...

This paper provides evidence of the effect of immigration-based networks on German trade. Germany presents a particular interesting case study to examine the effect of ethnic networks on exports due to its high export dependence and its reserved migration policy. According to our results, we...

This paper extends the firm heterogeneity model of Melitz (2003) by introducing a new concept of endegenous investments in process R&D. The novelty is that if a firm invests more R&D its expected innovation return hazard rate stochastically dominates the return of less R&D investments. Due to...

This paper studies the effect of pharmaceutical regulation at the wholesale level, if markets are integrated by parallel trade, i.e. trade outside the manufacturerś authorized distribution channel. In particular, maximum wholesale margins, a restriction of pricing by the intermediary, and...

This paper analyzes the consequences of parallel trade on health care systems in a two-country model with a vertical distributor relationship. In particular, two cost-sharing systems - coinsurance and indemnity insurance - are compared with respect to changes in copayments and public health...

This paper studies externalities of nationally determined cost-sharing systems, in particular coinsurance rates (patients pay a percentage of the price), under pharmaceutical parallel trade in a two-country model with a vertical distributor relationship. Parallel trade generates a...

We investigate the effects of demographic change and human capital accumulation on trade and productivity of domestic firms. In so doing we integrate a micro-founded education and fertility decision of households into a model of international trade with firm heterogeneity. Our framework leads to...

The retail sectors in many industrialized countries have experienced a large increase in concentration and the appearance of so-called "retail deserts", areas of low retail provision. This study addresses the role of international trade in this process. The analysis shows that by raising product...

The paper quantifies the impact of agglomeration economies on the clustering of German firms. Therefore, I use the 2006 Innobarometer survey, which focuses on cluster characteristics and activities of German firms, to empirically identify agglomeration economies derived from the New Economic...

This paper models different external reference pricing schemes - a price cap based on the drug price in one or two countries and on the minimum or average drug price - in a three-country framework. It studies the choice of external reference pricing schemes in one country as well as its effect...
