Empirical Properties of Inflation Expectations and the Zero Lower Bound

Abstract: Survey data on expectations shows that households have heterogeneous inflation expectations and their inflation expectations respond sluggishly to realized shocks to future inflation. By contrast, in models with a zero bound on the nominal interest rate currently used for monetary and fiscal policy analysis, households' inflation expectations are not heterogeneous and not sticky. This paper solves a New Keynesian model with a zero lower bound in which households have dispersed information. Households' inflation expectations are heterogeneous and sticky. The main properties of the model are: (1) the deflationary spiral in bad states of the world is less severe than under perfect information, (2) central bank communication (without a change in current or future policy) affects consumption and the sign of this effect depends on whether the zero lower bound is binding, i.e., an announcement that increases consumption when the zero lower bound is not binding reduces consumption when the zero lower bound is binding, (3) a commitment to future inflation can reduce consumption, (4) the government spending multiplier can be negative, and (5) shocks to uncertainty can have first-order effects.
