Implementation in Minimax Regret Equilibrium

  • Ludovic Renou

    ()

  • Karl H. Schlag

This note studies the problem of implementing social choice correspondences in environments where individuals have doubts about the rationality of their opponents. We postulate the concept of "-minimax regret as our solution concept and show that social choice correspondences that are Maskin monotonic and satisfy the no-veto power condition are implementable in "-minimax regret equilibrium for all " ? [0, 1).
