Arrow-Debreu equilibria with asymptotically heterogeneous expectations exist

Author

  • Riedel, Frank

Abstract

In infinite horizon economies only local equivalence of beliefs is needed to ensure the existence of an Arrow-Debreu equilibrium. In fact, agents can even disagree completely in the long run in the sense that asymptotically, their beliefs are singular.
