Title Recurrent Preemption Games
Author Hitoshi Matsushima
Abstract I consider a new model of an infinitely repeated preemption game with random matching, termed the recurrent preemption game, wherein each player’s discount factor depends on whether she wins the current game. This model describes sequential strategic technology adoptions in which a company becomes outdated by failing to maintain a position at the forefront of innovation. Assuming incomplete information about the presence of a rival, I clarify how the prominence of the innovator’s dilemma influences the degree of excessive competition in preemption. I also reveal interesting properties demonstrated by the unique symmetric Nash equilibrium of the recurrent preemption game.
Keywords Recurrent Preemption Game, Strategic Technology Adoption, Innovator’s Dilemma, Unique Equilibrium, Random Technology.
