In this paper we endogenize fixed price time-dependent rules to examine the output effects of monetary disinflation. We derive the optimal rules in and out of inflationary steady states, and develop a methodology to aggregate individual pricing rules which vary through time. Because of strategic...

This paper analyzes the implications of heterogeneity in price setting for the real effects of monetary shocks. Starting from otherwise standard sticky price and sticky information models, I introduce ex-ante heterogeneity in terms of price setting frictions, and compare the resulting dynamics...

We describe a strategy for the analysis of experimentally derived gene expression signatures and their translation to human observational data. Sparse multivariate regression models are used to identify expression signature gene sets representing downstream biological pathway events following...

There is ample evidence that the frequency of price adjustments differs substantially across sectors. This paper introduces sectoral heterogeneity in price stickiness into an otherwise standard sticky price model to study how it affects the dynamics of monetary economies. Qualitative and...

We estimate a dynamic, stochastic, general equilibrium model of the Brazilian economy taking into account the transition from a currency peg to inflation targeting that took place in 1999. The estimated model exhibits quite different dynamics under the two monetary regimes. We use it to produce...

We use a standard sticky-price model to provide evidence on three mechanisms that can reconcile somewhat frequent price changes with large and persistent real effects of monetary shocks. To that end, we estimate a semi-structural model for the U.S. economy that allows for varying degrees of real...
