Guessing Games and People Behaviours: What Can we Learn?

In this paper we address the topic of guessing games. By developing a generalised theory of naïveté, we show how Güth et al..s result (i.e. convergence toward interior equilibria is faster than convergence toward boundary equilibria) is compatible with Nagel.s theory of boundedly rational behaviour. However, we also show how, under new model parameterisation, neither Güth et al..s story of convergence towards interior equilibria, nor Nagel.s theory of boundedly rational behaviour are verified. We conclude that the results of Nagel (1995) and Güth et al. (2002), however interesting, are severely affected by the ad hoc parameterisation chosen for the game.
