This paper proposes an empirical framework for measuring the effects of entry in
concentrated markets. Building on models of entry in atomistically competitive markets,
the authors show how the number of producers in an oligopolistic market varies with
changes in demand and market competition. These analytical results structure the
authors' empirical analysis of competition in five retail and professional industries.
Using data on geographically isolated monopolies, duopolies, and oligopolies, they
study the relationship between the number of firms in a market, market size, and
competition. The authors' empirical results suggest that competitive conduct changes
quickly as the number of incumbents increases.
