This paper investigates monetary policy in a heterogeneous agent new Keynesian (HANK) model where agents face idiosyncratic income risk and use adaptive learning in order to form their expectations. Households experience different histories and observe different idiosyncratic variables. This...

This paper revisits monetary policy in a heterogeneous agents new Keynesian (HANK) model where agents use adaptive learning (AL) in order to form their expectations. Due to the households' finite heterogeneity triggered by idiosyncratic unemployment risk, the model is subject to micro-founded...

We study the impact of anticipated fiscal policy changes in the Ramsey economy when agents form expectations using adaptive learning. We extend the existing framework by distortionary taxes as well as elastic labour supply, which makes agents' decisions non-predetermined but more realistic. We...

We present new results for the performance of Taylor rules in a New Keynesian model with heterogeneous expectations. Agents have either rational or adaptive expectations. We find that depending on the particular rule, expectational heterogeneity can create or increase the set of policies that...
