Abstract:
This paper models entrepreneurship as the entrepreneur's information processing activity in order to predict changes in demand and reallocate resources. The results show that allocative efficiency---and therefore aggregate productivity---increases through intensified competition by entrepreneurs grasping at opportunities. This fierce competition leads to price reductions that result in the improvement of measured aggregate productivity. The price reduction also forces relatively less able entrepreneurs to become workers. As resources are then dealt with only by relatively talented entrepreneurs, this selection effect also increases aggregate productivity. The paper also discusses how the selection effect influences the distribution of firm size.
