The growing importance of shared networks, shared platforms and shared standards leads to a renewed discussion of the essential facilities doctrine of antitrust. This is an area where European law and American law have diverged. In Trinko (2007), the U.S. Supreme Court came close to abolishing...

What is the best way to reward innovation? While prizes avoid deadweight loss, intellectual property selects high social surplus projects. Optimal innovation policy thus trades off the ex-ante screening benefit and the ex-post distortion. It solves a multidimensional screening problem in the...

Motivated by the higher price sensitivity and service homogenisation in the airline industry in recent years, we propose a new methodology to deal with transaction prices and to estimate the effect of alliances in the US domestic market. The assumption that airlines compete on price allows us to...

We study the effect of encouraging private actions for breaches of competition law. We develop a model in which a plaintiff, who may have private information about whether a breach of law has been committed, decides whether to open a case against a defendant. If opened, the case may be settled...

This paper identifies strategies to build a library consortium from a long term point of view. Contrary to the conventional wisdom to build a consortium around groups of homogenous institutions (Davis, 2002), we find that libraries with similar preferences are likely to lose from building a...

We present a model where the Antitrust Authority is privately informed about the strength of the case against a given cartel. In this context, the Antitrust Authority may obtain cartel members' confessions even when it opens an investigation knowing that it has no chance to find hard evidence....

It is well-known from Innes and Sexton (1993, 1994) that divide-and-conquer contracts allow an incumbent facing a potential entrant to extract more surplus from buyers and hence buyers suffer from the strategy. In this paper, we show that when sellers compete by offering personalized non-linear...

Electronic academic journal websites provide new services of text and/or data mining and linking, indispensable for efficient allocation of attention among abundant sources of scientific information. Fully realizing the benefit of these services requires interconnection among websites. Motivated...

We consider competition among sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. We study how bundling affects competition for slots. Under independent pricing, equilibrium often does not exist and hence the outcome is often inefficient. When...

We investigate the interactions between managers’ incentives to collude or compete, and incentives to exert effort. A manager privately chooses the competitive strategy of the firm, and his own effort to improve productivity; He may substitute collusion to effort to increase profits. High...
