We analyze the competitive e?ects of backward vertical integration by a partially vertically integrated ?rm that competes with non-integrated ?rms both upstream and downstream. We show that vertical integration is procompetitive under fairly general conditions. It can be anticompetitive only if...

We analyze the competitive effects of backward vertical integration by a partially vertically integrated firm that competes with non-integrated firms both upstream and downstream. We show that vertical integration is procompetitive under fairly general conditions. It can be anticompetitive only...

We analyze the competitive effects of backward vertical integration when firms exert market power upstream and compete à la Cournot downstream. Contrasting with previous literature, a small degree of vertical integration is always procompetitive because efficiency gains dominate foreclosure...

We consider the canonical directed search framework in which sellers play pure strategies and assume that buyers play strategies that are monotone in prices, can remain inactive and choose to do so whenever their payoff from participating is zero regardless of what the other buyers do. We show...

Mechanisms according to which private intermediaries or governments charge transaction fees or indirect taxes are prevalent in practice. We consider a setup with multiple buyers and sellers and two-sided independent private information about valuations. We show that any weighted average of...

This paper estimates the cost of using simple percentage fees rather than the broker optimal Bayesian mechanism, using data for real estate transactions in Boston in the mid-1990s. This counterfactual analysis shows that interme-diaries using the best percentage fee mechanisms with fees ranging...
