True Monopolistic Competition as a Result of Imperfect Information
重述了哈特对大规模垄断竞争的定义，并指出消费者不完全信息可能使寡头市场转变为真正的垄断竞争市场。
The paper restates Hart's [1985a, 1985b] definition of large group monopolistic competition, distinguishes it from oligopolistic competition, and raises the question of whether there are reasonable circumstances that give rise to true monopolistic competition as defined. The purpose is to show that consumers' imperfect information may create conditions that will turn an otherwise oligopolistic market into a truly monopolistically competitive one.
