Industry sunk costs and entry dynamics

We explore an investment game where industry sunk costs provide anincentive for a firm to be a follower into the market as opposedto a leader. For some parameter values, every firm could have adominant strategy to wait, even though immediate entry is sociallyoptimal - this is a like prisoners' dilemma. In equilibrium, afirm is more likely to have a dominant strategy to wait with anincrease in the number of potential entrants. Finally, theequilibrium can display an entry cascade.
