There is a growing concern that U.S. merger control may have been too lenient, but empirical evidence remains limited. Event studies have been used as one method to acquire empirical insights into the competitive effects of mergers. However, existing work suffers from strong identifying...

In this paper we examine the interaction between the different modesof market access commitments inservices (cross-border and establishment) market structure, andregulation. In this context, we focus on theimpact of improved domestic market access for a foreign serviceprovider on a domestic...

We are concerned with trade in transport services (not cabotage butrather international shipping, transport,and related logistical services) and the importance of competitionand market structure in the sector. Weexamine implications of liberalization for profits, trade, andnational gains from...

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 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 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...

We propose a tractable method for estimation of a simultaneous search model for differentiated products that allows for observed and unobserved heterogeneity in both preferences and search costs. We show that for type I extreme value distributed search costs, expressions for search and purchase...

Antitrust laws prohibit private firms to coordinate their market behavior, yet many types of interfirm cooperation are legal. Using laboratory experiments, we study spillovers from legal cooperation in one market to non-competitive prices in a different market. Our theoretical framework predicts...

We analyze the behavior of producers who compete through price competition in a social environment from a sociological point of view. The standard model of Bertrand price competition is enriched with producers who follow a "Win Cooperate, Lose Defect" (WCLD) strategy. This strategy is a...

This paper studies whether a regulator needs to correct the route structure choice by carriers with market power in the presence of congestion externalities, in addition to correct their pricing. We account for passenger benefits from increased frequency, passenger connecting costs, airline...
