An Extended Duopoly Game


  • John C. Eckalbar


The author shows how principles and intermediate economic students can gain a feel for strategic price setting by playing a relatively large oligopoly game. The author constructs a playoff matrix and discusses various strategies and outcomes. The game extends to a continuous price space and outlines various applications appropriate for intermediate micro students. Finally, to make it easier for others to tinker with the assumptions of the game, the author can provide the Mathematica code used to generate the table and figures.
