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...

Using only aggregate data as observables, we estimate multi-sector sticky-price models for twelve countries, allowing the degree of price stickiness to vary across sectors. We use a specification that allows us to extract information about the underlying cross-sectional distribution from...

A three-sector model with a suitably chosen distribution of price stickiness can closely approximate the response to aggregate shocks of New Keynesian models with a much larger number of sectors, allowing for their estimation at much reduced computational cost

We study how real exchange rate dynamics are affected by monetary policy in dynamic, stochastic, general equilibrium, sticky-price models. Our analytical and quantitative results show that the source of interest rate persistence - policy inertia or persistent policy shocks - is key. In the...

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 entertain various alternatives for the source and nature of infrequent information. In two benchmark...

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. We examine this interaction in a model with endogenous time-dependent pricing. Both the endogenous initial degree of price rigidity and changes in the duration of price spells during...

We study the purchasing power parity (PPP) puzzle in a multisector, two-country, sticky-price model. Sectors differ in the extent of price stickiness, leading to heterogeneous sectoral real exchange rate dynamics. Deviations from PPP are more volatile and persistent than in an otherwise...

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...
