Abstract
We raise a novel question to inform our long-standing research agenda that studies public information as a policy tool: can information about the social interactions of others change even equilibrium behaviour, where beliefs are typically assumed to be correct? We examine this question focusing on the well-known ‘centipede game’: a multistage trust interaction, where it is socially beneficial to reach later stages. We develop a simple learning-motivated equilibrium model with heterogeneous agents. We first extend a model of learning in Bayesian games (Dekel, Fudenberg and Levin, 2004) to incorporate aggregate information and apply it to the centipede game. Our model combines self-confirming equilibrium and social preferences. Unlike standard models, our model predicts that aggregate feedback has clear long-run effects. We also provide tentative experimental evidence on different forms of feedback in the centipede game, finding weak effects of aggregate feedback.
