Learning by imitation in games: Theory, field and lab

Datum: 25 april 2014
Tid: 13:00-14:30

Erik Mohlin, Oxford University

We exploit a unique opportunity to study how a large population of players in the field learn to play a novel game which has a complicated and non-intuitive mixed strategy equilibrium. We argue that standard models of belief-based learning and reinforcement learning have difficulties in explaining the data, but that a simple model of global imitation of strategies that are similar to previous successful strategies can do so. We study the convergence properties of our proposed imitation learning model, by means of stochastic approximation, and corroborate our findings using laboratory data.
