News shocks or parametric indeterminacy? An observational equivalence result in linear rational expectations models

  • Sorge, Marco M.

Abstract

This paper studies identification in linear rational expectations models with news shocks. We show that news-driven models and indeterminate equilibrium economies with i.i.d. fundamentals are observationally equivalent. This finding calls for carefully designing empirical investigations of news shocks in estimated DSGE models.
