A Dynamic Model of Entry Deterrence
研究了在位企业通过研发和销售推广积累知识及商誉来遏制潜在竞争者进入市场的动态决策问题，包括何时允许对手进入。
It has been recognized in a number of recent studies on oligopoly and potential competition that a firm may deter entry by engaging in different types of irreversible investments. This paper reports on an investigation of this issue in a dynamic setting. The established firm is assumed to build up a stock of knowledge and goodwill by investing in R&D and sales promotion, and these stocks are assumed to erode over time. The established firm then has to decide whether or not to deter entry and, eventually, when to permit a potential competitor to enter the market.
