I summarize recent progress made in the literature on inflation dynamics. This has been a very productive area of research due to the development of the so-called New Keynesian model and the availability of new macroeconomic and microeconomic evidence. Nevertheless, a number of problems still...

Macroeconomic and microeconomic data paint conflicting pictures of price behavior. Macroeconomic data suggest that inflation is inertial. Microeconomic data indicate that firms change prices frequently. We formulate and estimate a model which resolves this apparent micro - macro conflict. Our...

The literature has shown that product market frictions and firms dynamic play a crucial role in reconciling standard DSGE with several stylized facts. This paper studies optimal monetary policy in a DSGE model with sticky prices and oligopolistic competition. In this model firms' monopolistic...

This paper formulates and estimates a three-shock US business cycle model. The estimated model accounts for a substantial fraction of the cyclical variation in output and is consistent with the observed inertia in inflation. This is true even though firms in the model reoptimize prices on...

This paper generates persistent effects of a monetary disturbance in the context of staggered price-setters. Previous research has been restricted by the CES functional form to price-setting rules that are constant markups over marginal costs. The present paper considers a translog form for...

We consider a DSGE model in which firms follow one of four price-setting regimes: sticky prices, sticky-information, rule-of-thumb, or full-information flexible prices. We allow for each type of firm to coexist and interact via their respective price-setting decisions. The parameters of the...

After many years, many critiques, and many variations, the staggered wage and price setting model is still the most common method of incorporating nominal rigidities into empirical macroeconomic models used for policy analysis. The aim of this chapter is to examine and reassess the staggered...

This paper looks at the implications of heterogeneous beliefs for inflation dynamics. Following a monetary policy shock, inflation peaks after output, is inertial, and can be characterized by a Hybrid Phillips Curve. It presents a novel channel through which systematic monetary policy can affect...

Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually to a monetary policy shock, ii) announced and credible disinflations are contractionary and iii) inflation...
