This paper is motivated by the empirical regularity that industries differ greatly in the level of firm turnover, and that entry and exit rates are positively correlated across industries. Our objective is to investigate the effect of sunk costs and, in particular, market size on entry and exit...

We survey recent developments in the theoretical and empirical literature on the economic effects of environmental regulation on various aspects of market structure including entry, exit, and size distribution of firms and market concentration.

This paper analyzes the evolution of the distributions of output and employment across firms in U.S. manufacturing industries from 1963 until 1997. The firm size distribution changes significantly as an industry goes through stages of its life-cycle. The evolutions of the employment and output...

Predatory pricing--a deliberate strategy of pricing aggressively in order to eliminate competitors--is one of the more contentious areas of antitrust policy and its existence and efficacy are widely debated. The purpose of this paper is to formally characterize predatory pricing in a modern...

This paper studies the contribution of demand, costs, and strategic factors to the adoption of hub-and-spoke networks in the US airline industry. Our results are based on the estimation of a dynamic game of network competition using data from the Airline Origin and Destination Survey with...

We propose a dynamic model of an oligopoly industry characterized by spatial competition between multi-store retailers. Firms compete in prices and decide where to open or close stores depending on demand conditions and the number of competitors at different locations, and on location-specific...

We develop a model of bidding markets with financial constraints à la Che and Gale [15] in which two firms choose their budgets optimally and we extend it to a dynamic setting over an infinite horizon. We provide three main results for the case in which the exogenous cash-flow is not too large...

We provide a general model of dynamic competition in an oligopolistic industry with investment, entry, and exit. To ensure that there exists a computationally tractable Markov perfect equilibrium, we introduce firm heterogeneity in the form of randomly drawn, privately known scrap values and...
