Learning and the saddle point property

Author

Listed:
  • Gauthier, Stephane

Abstract

This note shows that there are close connections between the determinacy of a stationary state equilibrium and its stability under learning whenever agents try to estimate both the law of motion of the state variable and the stationary state value.
