    Evidence shows that firms build their market position by accumulating knowledge protected by secrecy, patents and other appropriation devices. I explore the implications of this fact in a model economy where oligopolistic firms establish in-house R and D programs. In symmetric equilibrium, the number of firms determines concentration and firm size. These determine the scale and the efficiency of R and D operations and the rate of innovation. The number of firms, moreover, is endogenous and determined jointly with the rate of growth by the zero-profit condition. This property yields new results. For example, the scale effect of population size may be negative. The market allocation of resources is not Pareto optimal. I discuss the nature of this distortion.
