Technology Adoption With Forward Looking Agent

Abstract

We investigate the effects of forward looking behavior in technology adoption. The setup is an overlapping generation model where agents choose between two alternative networks taking in consideration both the installed base and the expected base. The latter element is the distinctive feature of our approach. We use results from the global games literature to select the unique equilibrium on which agents coordinate their expectations. We consider both the cases of incompatible and compatible technologies, and show that technologies cannot lock-in, while the adoption path exhibits hysteresis. Network choices are characterized both in terms of their long run properties and expected time of adoption.
