The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an...

The health care professions in Europe have been subject to substantial entry and conduct regulation. Most notably, pharmacies have frequently received high regulated markups over wholesale costs, and have been protected from additional competition through geographic entry restrictions. We...

This paper empirically investigates the effectiveness of competition policy by estimating its impact on Total Factor Productivity (TFP) growth for 22 industries in 12 OECD countries over the period 1995-2005. We find a robust positive and significant effect of competition policy as measured by...

This paper introduces three methodological advances to study the optimal design of static and dynamic markets. First, we apply a mechanism design approach to characterize all incentive-compatible market equilibria. Second, we conduct a normative analysis, i.e. we evaluate alternative competition...

This paper reports results from an experiment studying how fines, leniency programs and reward schemes for whistleblowers affect cartel formation and prices. Antitrust without leniency reduces cartel formation, but increases cartel prices: subjects use costly fines as (altruistic) punishments....

This paper provides a critical review of competition policy in Switzerland. We analyse the legal statute, the institutional arrangements for its implementation and the case law since 1985. We find that the Cartel Commission, which was given wide discretion by the law, has been relatively immune...

This paper explores the possibility of governments seeking to agree to apply competition policy-based considerations and disciplines in the context of unfair trade allegations before turning to `standard' antidumping remedies. The premise of proponents of antidumping action is that the existence...

Motivated by the general lack of empirical scholarship concerning the cross-national environment for competition policy, I present measures here of the overall resources dedicated to competition policy and the merger policy work-load for thirty-two antitrust jurisdictions over the 1992-2007...

Modern economies predominantly rely on the working of markets. To ensure that markets are a level playing field for economic agents, competition policies are usually included in the legal framework that regulates economic activities. Portugal is no exception to this rule. This paper reviews the...
