A relation between inflation and the path of average marginal cost (often measured by unit labor cost) implied by the Calvo (1983) model of staggered pricing --- sometimes referred to as the "new-Keynesian Phillips curve"--- has been the subject of extensive econometric estimation and testing....

The COVID-19 pandemic presents a challenge for stabilization policy that is different from those resulting from either "supply" or "demand" shocks that similarly affect all sectors of the economy, owing to the degree to which the necessity of temporarily suspending some (but not all) economic...

The massive expansion of central-bank balance sheets in response to recent crises raises important questions about the effects of such "quantitative easing" policies, both their effects on financial conditions and on aggregate demand (the intended effects of the policies), and their possible...

A model is proposed in which stochastic choice results from noise in cognitive processing rather than random variation in preferences. The mental process used to make a choice is nonetheless optimal, subject to a constraint on available information-processing capacity that is partially motivated...

This paper reviews a variety of alternative approaches to the specification of the expectations of economic decisionmakers in dynamic models, and reconsiders familiar results in the theory of monetary and fiscal policy when one allows for departures from the hypothesis of rational expectations....

A number of commentators have argued that the desirability of inflation targeting as a framework for monetary policy analysis should be reconsidered in light of the global financial crisis, on the ground that it requires neglect of the implications of monetary policy for financial stability....

This paper reviews the theory of optimal monetary stabilization policy, with an emphasis on developments since the publication of Woodford (2003). The structure of optimal policy commitments is considered, both when the objective of stabilization policy is defined by an arbitrarily specified...

This paper explains the key factors that determine the effectiveness of government purchases as a means of increasing output and employment in New Keynesian models, through a series of simple examples that can be solved analytically. Delays in the adjustment of prices or wages can allow for...

I present a generalization of the standard (full-information) model of state- dependent pricing in which decisions about when to review a firm's existing price must be made on the basis of imprecise awareness of current market conditions. The imperfect information is endogenized using a variant...

Forecast targeting is an innovation in central banking that represents an important step toward more rule-based policymaking, even if it is not an attempt to follow a policy rule of any of the types that have received primary attention in the theoretical literature on optimal monetary policy....
