Welfare Analysis of Free Entry in a Dynamic General Equilibrium Model
This paper presents a welfare analysis of free entry equilibrium in dynamic general equilibrium environments with oligopolistic competition. First, we show that a marginal decrease in the number of firms at the free entry equilibrium improves social welfare. Second, we show that if a government can control the number of entrants intertemporally so as to maximize the level of social welfare, the number of entrants under free entry may be less than the second-best number of entrants. Capital accumulation plays an important role in determining whether excess entry occurs.
