Cyclic Pricing by a Durable Goods Monopolist: Corrigendum

Abstract

In this paper we make a new analysis of the model presented in Conlisk, Gerstner and Sobel (1984). They propose a model in discrete time, such that at each period a new cohort of agents enters the market –each cohort is composed by two types of agents, high value and low value agents– and a monopolist offering a durable good. They argue that in this model the monopolist charge a cyclic price path as a subgame perfect equilibrium. Instead of this, we show that either the monopolist charge a single price forever as a subgame perfect equilibrium or a subgame perfect equilibrium does not exist.Durable goods, monopolist, heterogenous agents, subgame perfect equilibrium
