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...

In this paper we study, as in Jeon-Menicucci (2009), competition between sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. This paper considers sequential pricing and complements our main paper (Jeon- Menicucci, 2009) that considers simultaneous...

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...

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 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...

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...

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...

While vertical integration is traditionally seen as a solution to the hold-up problem, this paper highlights instead that it can generate hold-up problems — for rivals. We first consider a successive duopoly where competition among suppliers eliminates any risk of hold-up; downstreamfirms thus...
