On the dynamics of a restricted Cournot–Puu triopoly: Firms survival and complexity

摘要

In this paper we explore the dynamics of a restricted Cournot–Puu triopoly. We focus our interest in a triopoly when two firms have both the same marginal costs and initial conditions and explore the dynamics in this situation which was introduced in Puu (1998) [14]. We find conditions for removing the other firm from the market, and analyze the complexity of the map by means of sample permutation entropy.
