This paper investigates the effectiveness of central bank forward guidance while relaxing two standard macroeconomic assumptions: rational expectations and frictionless financial markets. The results show that the addition of financial frictions amplifies the differences between rational expectations and adaptive learning to forward guidance. During a period of economic crisis, output under rational expectations displays more favorable responses to forward guidance than under adaptive learning. These differences are exacerbated when compared with a similar analysis without financial frictions. Thus, monetary policymakers should consider the way in which expectations and credit frictions are modeled when examining the effects of forward guidance.
