Abstract

This paper develops an econometric model of firm entry, competition, and
exit in oligopolistic markets. The model has an essentially unique symmetric
Markov-perfect equilibrium, which can be computed very quickly. We show
that its primitives are identified from market-level data on the number of
active firms and demand shifters, and we implement a nested fixed point
procedure for its estimation. Estimates from County Business Patterns data
on U.S. local cinema markets point to tough local competition. Sunk costs
make the industry's transition following a permanent demand shock last 10
to 15 years.
