This paper considers the effects of raising the cost of entry for a potential competitor on infinite-horizon Markov-perfect duopoly dynamics with ongoing demand uncertainty. All entrants serving the model industry incur sunk costs, and exit avoids future fixed costs. We focus on the unique...

Interstate highway openings were permanent, anticipated demand shocks that increased gasoline demand and sometimes shifted it spatially. We investigate supply responses to these demand shocks, using county-level observations of service station counts and employment and data on highway...

This paper develops a tractable model for the computational and empirical analysis of infinite-horizon oligopoly dynamics. It features aggregate demand uncertainty, sunk entry costs, stochastic idiosyncratic technological progress, and irreversible exit. We develop an algorithm for computing a...

This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level panel data on the number of producers and consumers using a nested fixed-point algorithm. We show that the model has an essentially unique symmetric...

This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level data on demand shifters and the number of producers. We show that the model has an essentially unique symmetric Markov-perfect equilibrium that can be...

This paper studies the entry and exit of U.S. manufacturing plants over the business cycle and compares the results with those from a vintage capital model augmented to reproduce observed features of the plant life cycle. Looking at the entry and exit of plants provides new evidence supporting...

We measure industry evolution following permanent changes in the level and location of demand for gasoline in hundreds of counties during the time surrounding the completion of Interstate Highway segments. We find that the timing and margin of adjustment depends on whether the new highway is...
