A note on credible spatial preemption in an entry-exit game

摘要

I investigate how an incumbent firm deters entry by crowding the market, even when the incumbent can withdraw its stores in response to entry. In a two-location model, Judd (1985) shows such spatial entry deterrence is not credible. In contrast, I demonstrate spatial preemption can be credibly employed in a circular-city model if the incumbent can build its stores on sufficiently many locations and transportation costs are linear.
