Are Non-Fundamental Equilibria Learnable in Models of Monetary Policy?

  • Honkapohja, Seppo
  • Mitra, Kaushik

Recent models of monetary policy can have indeterminacy of equilibria. The indeterminacy property is often viewed as a difficulty of these models. We consider its significance using the learning approach to expectations formation by employing expectational stability as a robustness criterion for different equilibria. We derive the expectational stability and instability conditions for forward-looking multivariate models, both with and without lags, that cover a wide range of monetary policies proposed in the literature.
