Imperfect Monitoring and Impermanent Reputations

  • Martin W. Cripps
  • George J. Mailath
  • Larry Samuelson

We study the long-run sustainability of reputations in games with imperfect public monitoring. It is impossible to maintain a permanent reputation for playing a strategy that does not play an equilibrium of the game without uncertainty about types. Thus, a player cannot indefinitely sustain a reputation for noncredible behavior in the presence of imperfect monitoring. Copyright The Econometric Society 2004.
