In the infinite horizon alternating price setting duopoly of Maskin and Tirole (1988), a focal price equilibrium and an equilibrium consisting of Edgeworth cycles coexist. In this study we investigate which of these two equilibria is more likely to emerge by means of a laboratory experiment. In 20 out of 27 observations the focal price equilibrium emerges, while price cycles are observed in only one observation. Furthermore, we study the duopoly in case of a long but finite horizon. Although the corresponding unique subgame-perfect equilibrium consists of Edgeworth cycles, experimentally we still observe a focal price in the majority of the observations. Nevertheless, price cycles are observed far more often than for the infinite horizon setting.
