This paper studies an advantage of commitment over discretion when a central bankobserves only noisy measures of current inflation and output, in the context of an optimizingmodel with nominal-price stickiness. Under a commitment regime, if current policy turns outto be too expansionary...

This paper provides a stylized choice-thoretic model to analyze optimal monetary policies among interdependent economies. In response to marcoeconomic shocks, policymakers strike a balance between two objectives. The first is to stabilize marginal costs and markups to offset the distortions...

When a policymaker is better informed than the public, public beliefs about the hidden informationemerge as additional state variables, managed by the policymaker. General methodsare presented to compute optimal commitment and discretion policies.Under commitment, policy is additive in two...

Monetary policy is most effective when public beliefs about future policies are activelymanaged. This is the appeal of policy rules and commitment strategies, typically absent underdiscretion. But when a policymaker has some private information — as is the case in reality— belief management...

The paper evaluates the performance of three popular monetary policy rules when the central bank is learning aboutthe parameter values of a simple New Keynesian model. The three policies are: (1) the optimal non-inertial rule; (2)the optimal history-dependent rule; (3) the optimal price-level...

This paper considers the determination of aggregate price level under dispersed information.A Central Bank sets policy in response to its noisy measure of the price level, andeach agent makes its decisions by observing a subset of data. Information revealed to theagents and the bank is...

The New Keynesian Phillips Curve is at the center of two raging empirical debates. First, how can purely forward looking pricing account for the observed persistence in aggregate inflation. Second, price-setting responds to movements in marginal costs, which should therefore be the driving force...

The evidence from many experiments suggests that people are heterogeneous with regard to their abilities to make rational, forward looking, decisions. This raises the question when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate...

We examine the effects of the Czech National Bank communication, macroeconomic newsand interest rate differential on exchange rate volatility using generalized autoregressiveconditional heteroscedasticity model. Our results suggest that central bank communicationhas a calming effect on exchange...
