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 examine the setting of national competition policy in a two-country setting,emphasizing the relationship of trade to the goals of competition policy (suchas the degree and nature of competition). The issues we address involve thegeneral equilibrium distributional effects of competition...

We examine interaction between trade in goods and market power in domestic trade and distribution, developing a model that highlights this interaction. Theory points to an expected linkage between service sector competition and goods trade, one supported by econometrics involving import patterns...

We examine antitrust rules in a two county general equilibrium trade model, contrasting national and multilateral (cooperative) determination of competition policy, exploring the properties of the policy equilibrium. It is not imperfect competition, but variation in competitive stance between...

As a part of their industry or competition policies governments decide whether to allow for free market entry of firms or to regulate market access. We analyze a model where governments (ab)use these policy decisions for strategic reasons in an international setting. Multiple equilibria of this...
