Abstract

This note analyses the adoption and diffusion of innovations in a horizontally differentiated Cournot duopoly in which firms have to choose the dates for adopting a cost-reducing new technology like in Reinganum (1981a). We prove that product differentiation crucially matters in the diffusion pattern of the innovation and in the comparison between the adoption timing in the decentralized economy Vs the social optimum .
