We re-examine the view that a ban on price discrimination in input markets is particularly desirable in the presence of buyer power. This argument crucially depends on an inverse relationship between downstream firms’ profits and the uniform input price. Assuming different input efficiencies...

We analyze how network regulation affects investment into network infrastructure and complementary services. While regulation negatively affects investment incentives in the regulated network market, the effects of network regulation on investment in complementary services can be either negative...

Katz (1987), DeGraba (1990), and Yoshida (2000) have formulated theories that price discrimination bans in intermediary goods markets tend to have positive effects on allocative, dynamic and productive efficiency, respectively. We show that none of these results is robust vis-à-vis endogenous...

Am 26. Februar 2007 hat die EU-Kommission ein beschleunigtes Vertragsverletzungsverfahren gegen Deutschland wegen der Einführung von angeblichen "Regulierungsferien" in dem jüngst novellierten Telekommunikationsgesetz (TKG) eröffnet. Die Kommission vermutet, dass die dort getroffene...

This paper examines how different unionisation structures affect firms' innovation incentives and industry employment. We distinguish three modes of unionisation with increasing degree of centralisation: (1) 'Decentralisation' where wages are determined independently at the firm-level, (2)...

This paper examines how unionization structures that differ in the degree of wage centralization affect firms' incentives to increase labor productivity. We distinguish three modes of unionization with increasing degree of centralization: (1) “Decentralization” where wages are determined...

Many cartels are formed by individual managers of different firms, but not by firms as collectives. However, most of the literature in industrial economics neglects individuals' incentives to form cartels. Although oligopoly experiments reveal important insights on individuals acting as firms,...
