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...

This paper studies the impact of the adoption of ICT on the economic performance at the firm level, considering explicitly the interaction of adopting firms within the intermediate input market in Germany. The paper identifies and quantifies the importance of adoption externalities and knowledge...

Motivated by Manski and Tamer (2002) and especially their partial identification analysis of the regression model where one covariate is only interval-measured, we offer several contributions. Manski and Tamer (2002) propose two estimation approaches in this context, focussing on general...

Firm heterogeneity explains the productivity driven selection mechanism that determines aggregate productivity growth within industries. This paper empirically demonstrates that ICT has a robust impact on firm heterogeneity only when ICT is used intensively and jointly with specific ICT...

Leniency programs as a tool for cartel detection and cartel destabilization, have been implemented since the early nineties. Theoretical work has shown that leniency programs can be effective in enhancing cartel detection and deterrence, but these effects are not straight-forward. It is even...
