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 firm entry, competition, and exit in dynamic oligopolistic markets. The model entertains market-level demand and cost shocks, sunk entry costs, and parameters that capture economic barriers to entry and the toughness of price competition. Nevertheless...
