Informational Smallness in Rational Expectations Equilibria

  • Heifetz, A
  • Minelli, E

In an economy with asymmetric information, Rational Expectations Equilibria (REE) need not become asymptotically incentive compatible, even if many independent replicas of the economy are merged together. We identify a sub-class of REE for which this is nevertheless the case.
