摘要:
Profit maximization is the usual prerequisite for achievement of a perfectly competitive equilibrium. However, for a long time it has been thought that this principle of profit maximization can be replaced by natural selection. In an evolutionary model of an industry, where firms' outputs are chosen randomly, where entry occurs with no motivation, and where exit occurs when a firm's wealth becomes negative, this paper shows that the industry converges in probability to a perfectly competitive equilibrium as each firm gets infinitesimally small relative to the market, as the entry cost gets sufficiently small and as time gets sufficiently large.
