The paper demonstrates how the Estability principle introduced by Evans and Honkapohja can be applied to models with heterogeneous and private information in order to assess the stability of rational expectations equilibria under learning. The paper extends already known stability results for...

This paper examines E-stability, determinacy, and indeterminacy in a general class of regime-switching models with lagged endogenous variables. Using determinacy conditions from Cho (2016, 2020), our first result extends McCallum (2007) to models with time-varying parameters: the unique...

It is generally believed that excessive stock market volatility reflects non-mathematical market expectations that are driven by “irrational exuberance” or “animal spirits”. As shown in this paper, there is an alternative explanation. If ex-ante and ex-post expectations are calculated in...
