Over the past 15 years there has been remarkable progress in the specification and estimation of dynamic stochastic general equilibrium (DSGE) models. Central banks in developed and emerging market economies have become increasingly interested in their usefulness for policy analysis and...

This paper examines search with active learning and correlated information. We firstdevelop a simple model to show how correlation affects the decision to acquire information.A unique data set on fishing site choice by mid-Atlantic clam fishermen is used to test themodel predictions. Results...

We use a unique dataset of bond downgrades from a niche rating company that has been found to be reacting faster to publicly available information than its competitors. Using regime-switching models we propose risk measures to quantify stock return disturbances (distress costs) associated with...

A striking fact about pricing is the prevalence of \sales": large temporary price cuts followedby prices returning exactly to their former levels. This paper builds a macroeconomic modelwith a rationale for sales based on firms facing customers with different price sensitivities.Even if firms...

In a country with high probability of default, higher interest rates may render the currency lessattractive if sovereign default is costly. This paper develops that intuition in a simple model andestimates the effect of changes in interest rates on the exchange rate in Brazil using data from...

Recent literature on the design of optimal monetary policy has shown that deviations fromprice stability are small whenever prices are sticky. This paper reconsiders this issue byintroducing capital accumulation in the model. Optimal monetary policy in this setupimplies small deviations from...

This paper computes welfare-maximizing monetary and tax policy feedback rules in acalibrated dynamic general equilibrium model with sticky prices. The government makesexogenous final good purchases, levies a proportional income tax, and issues nominalone-period bonds. A quadratic approximation...

We extend the Carlstrom and Fuerst (American Economic Review,1997, 87, pp. 893–910) agency cost model of business cycles by includingtime-varying uncertainty in the technology shocks that affectcapital production. We first demonstrate that standard linearizationmethods can be used to solve the...

In the data, individual prices change frequently and by large amounts. In standardsticky price models, frequent and large price changes imply a fast response of the aggregate price level to nominal shocks. This paper presents a model in which price setting firms optimally decide what to observe,...
