Based on a stochastic dynamic model of a firm's optimal innovative behavior we derive a simultaneous equation system for product and process innovations with intertemporal spillover effects. We estimate various versions of the model with dichotomous Innovation data at the firm level by using a...

This paper analyzes the influence of Information structure on the process of knowledge accumulation in a differential game of duopolistic R&D competition. By comparing open-loop and feedback Nash equilibria, representing imperfect and perfect information structures, we show that in the feedback...
