We study the purchasing power parity (PPP) puzzle in a multisector, two-country, sticky-price model. Firms’ price stickiness differs across sectors, in accordance with recent microeconomic evidence on price setting in various countries. Combined with local currency pricing, these differences...

We characterize optimal state-dependent pricing rules under various forms of infrequent information. In all models, infrequent price changes arise from the existence of a lump-sum “menu cost.” We entertain various alternatives for the source and nature of infrequent information. In two...

We develop a multi-sector sticky-price DSGE (dynamic stochastic general equilibrium) model that can endogenously deliver differential responses of prices to aggregate and sectoral shocks. Input-output production linkages induce across-sector pricing complementarities that contribute to a slow...

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. In this paper, we examine how credibility affects the outcome of a disinflation in a model with endogenous time-dependent pricing rules. Both the endogenous initial degree of price...

We would like to propose a new framework for monetary policy analysis that encompasses, as a special case, the Neo-Wicksellian paradigm. A general form of an aggregate-demand equation reveals a role for liquidity, as well as less effective movements in future real rates with respect to current...

We propose a new framework for monetary policy analysis to study monetary policy normalization when exiting a liquidity trap. The optimal combination of reserves and interest rate policy requires an increase in liquidity (reserves) a few quarters after the policy rate is set at the effective...
