E-stability in the stochastic Ramsey model

Author

  • Evans, George W.

Abstract

Analytical expectational stability results are obtained for both Euler-equation and infinite-horizon adaptive learning in a simple stochastic growth model. The rational expectations equilibrium is stable under both types of learning, though there are important differences in the learning dynamics.
