Abstract
When innovation is followed by imitator entry, the degree to which the innovator can appropriate the rents induced by its innovations, influences the rate of innovative activity. The author's interest focuses upon the interaction between the rate of innovative activity and the length l of the delay between the innovation and imitation, in a model in which innovative activity generates a sequence of new innovations in the face of market saturation, a competitive motivation (to maintain the monopoly position), and a strategic motivation (to deter entry). The goal of the authors' analysis is to elicit the circumstances in which each force dominates. Because of these countervailing forces, the optimal rate of innovation may not be monotone in the delay l; furthermore, a more easily saturated market can benefit the innovator.
