SPATIAL ENTRY DETERRENCE UNDER OLIGOPOLY*
研究了线性市场中合谋的寡头企业如何通过调整价格来阻止潜在进入者，假设竞争对手不在市场边界争夺消费者，并推导出两种价格模式。
ABSTRACT. This paper examines colluding, oligopolistic firms in a linear market. By assuming that rivals do not compete for consumers at their market boundaries, it is shown that an equilibrium exists without adopting a convex transportation cost function. Two price profiles are derived. The first describes firm prices in the absence of threatened entry. The second details profit‐maximizing prices which forestall entrants. Given infinite relocation costs, threatened entry leads to price adjustments by the incumbent firms.
