Noncooperative Behavior by a Cartel as an Entry-Deterring Signal
研究潜在进入者面临事后利润不确定性时，事前利润越高进入越可能；均衡中，进入威胁迫使在位企业更竞争性地定价以阻止进入。
Recent work has investigated the effect of a potential entrant's uncertainty about postentry profits on the likelihood of his entering the market. It has always been assumed that the potential entrant knows the type of postentry solution, but lacks information on cost or as to whether the postentry solution will be cooperative or noncooperative. We find that entry is more likely, the greater is the preentry profit rate. In equilibrium, the threat of entry then forces the incumbent firms to act more competitively to deter entry.
