This paper uses merger simulations to predict post-merger prices for six major airline mergers from the 1980's, and compares these predictions with actual post-merger prices. Simulations which incorporate varying degrees of post-merger information allow us to decompose the actual price changes...

This paper considers the effects of joint negotiation when suppliers and intermediaries engage in bilateral negotiation over inclusion of a supplier’s product in an intermediary’s network. I identify conditions under which joint negotiation by two suppliers increases the suppliers’...

A “market” can be rigorously and precisely defined quantitatively, but the information to do so is typically not available. Instead, markets are often defined based on qualitative information, leading to the possibility of errors. I make some practical suggestions to mitigate such errors....

With the clamor rising over airport delays and with both the Congress and the Administration considering remedies, this paper advocates the use of market mechanisms, specifically slot auctions, to promote efficient usage of airport capacity, reduce airport delays, and, more generally, promote...

I model multimarket competition when consumers value firm scope across markets. Such competition is surprisingly common – consumers in many industries prefer firms that operate in more geographic and/or product markets. I show that these preferences permit firms of differing scopes to coexist...

This paper analyses the dynamic aspects of knowledge sharing in R&D rivalry. In a model where research projects consist of N sequential stages, our goal is to explore how the innovators' incentives to share intermediate research outcomes change with progress and with their relative positions in...

Large, urban tertiary care hospitals often acquire outlying community hospitals. One possible motivation is to increase referrals. Sophisticated acquirers may even attempt to concentrate additional referrals among more profitable patients. We explore these issues by studying 26 vertical...
