I analyze a quasi-natural experiment of fiber broadband rollout in a rural German area. The analysis particularly investigates the impact on real estate values. I find that there are strong and significant effects of fiber broadband deployment. These indicate that there are relevant personal...

The paper provides empirical evidence for the causal impact of broadband Internet on the economic performance of German firms. Performance is measured in terms of labour productivity and realised process and product innovations. The analysis refers to the early phase of DSL expansion in Germany...

We examine how different pass-through rates, from input- to final consumer prices, and different vertical contracts affect upstream market definition. Our theory model predicts that, under reasonable conditions, higher pass-through rates lead to definitions of larger upstream markets. Data from...
