One of the core building blocks of traditional economic theory is the concept of equilibrium, a state of the world in which economic forces are balanced and in the absence of external influences the values of economic variables remain static. Many traditional equilibrium models, or equilibria,...

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. This paper shows analytically that with the market selection...

This paper shows that a monopolistically competitive equilibrium can evolve without purposive profit maximization. Specifically, this paper formulates a precise evolutionary dynamic model of an industry where there is continuous entry of firms that randomly select their output levels on entry...
