Potential Competitors
in Preemption Games
 

Abstract
The purpose of this paper is to study the adoption of a new technology by a firm when the competitor comes into play at a random date that can be seen as her birth date. The presence of a competitor is thus only revealed when she invests. We show that there exists a unique Bayesian equilibrium that can be split into three stages. No firm will invest before a threshold T1 even if she is born before. After another threshold T2 that is strictly less than the date that maximizes the expected payoff function, any firm immediately invests at birth. In between, the equilibrium is in mixed strategies. On [T1, T2], newborn firms compete with firms that were born earlier.
