Dampened expectations in the Phillips Curve: A note

摘要

Dampened inflation expectations have a significant impact on the New Keynesian Phillips Curve. This dampening not only flattens the long run Phillips Curve, but it can also lead to a bias in the estimation of its short run slope. It also affects the response of a small NK model to demand shocks, and affects the optimal monetary policy: in particular, the price targeting result of the Ramsey policy is violated when there is dampening.
