Reputation in the Simultaneous Play of Multiple Opponents
研究一个在位者同时与多个进入者博弈时，声誉如何影响结果。发现增加同时进入者可能产生与序贯博弈截然不同的效果，且声誉主导未必对在位者有利。
Imagine that one player, the "incumbent" competes with several "entrants". Each entrant competes only with the incumbent, but observes play in all contests. Previous work shows that, as more and more entrants are added, the incumbent's reputation may dominate play of the game, if the entrants are faced in sequence. We identify conditions under which similar results obtain when the entrants are faced simultaneously, and we find specifications in which adding more simultaneous entrants has a dramatically different effect. We also show that, with either sequential or simultaneous play, incumbents need not prefer the situation in which their reputations can and do dominate play to the "informationally isolated" case in which each entrant observes only play in its own contest.
