We study the efficiency of oligopoly equilibria in a model where firms compete over capacities and prices. The motivating example is a communication network where service providers invest in capacities and then compete in prices. Our model economy corresponds to a two-stage game. First, firms...

We present a dynamic quantity setting game, where players may continuously adjust their quantity targets, but incur convex adjustment costs when they do so. These costs allow players to use quantity targets as a partial commitment device. We show that the equilibrium path of such a game is...

Commercial radio stations and advertisers have potentially conflicting interests about when commercial breaks should be played. This paper estimates an incomplete information timing game to examine stations' equilibrium timing incentives. It shows how identification can be aided by the existence...

The ready-to-eat cereal industry is characterized by high concentration margins, large advertising to sales ratios, and numerous introductions of new products. Previous researchers have concluded that the ready-to-eat cereal industry is a classic example of an industry with nearly collusive...

This paper studies the market provision of a specific type of public good: radio and television broadcasts. Its main focus is to explore the ability of the market to provide broadcasting efficiently in a world in which broadcasters earn revenues by selling time to advertisers and advertisements...

Consistent with two models of imperfect competition in the labor market, the efficient bargaining model and the monopsony model, we provide two extensions of a microeconomic version of Hall's framework for estimating price-cost margins. We show that both product and labor market imperfections...

Following a brief review of the U.S. domestic airline industry under regulation (1938-1978), we study the changes that have occurred in pricing, service, and competition in the 28 years since deregulation. We then examine some of the major public policy issues facing the industry: (a) the...

Markets are generally thought to avoid problems, such as tyranny of the majority, that arise when allocation is accomplished through collective processes. Yet, with fixed costs, differentiated product markets deliver only products desired by substantial constituencies. When consumers share...

The U.S. airline industry went through tremendous turmoil in the early 2000's. There were four major bankruptcies and two major mergers, with all legacy carriers reporting a large profit reduction. This paper presents a structural model of the airline industry, and estimates the impact of demand...

We argue that strategic interactions between firms in an oligopoly can explain the puzzling lack of high-powered incentives in executive compensation contracts written by shareholders whose objective is to maximize the value of their shares. We derive the optimal compensation contracts for...
