Multi-countru models have not been very successful in replicating features of the international transmission of business cycles. Standard models predict cross-country correlations of output and consumption which are respectively too low and loo high. In this paper, we built a multi-country model...

Modern business cycle theory involves developing models that explain stylized facts. For this strategy to be successful, these facts should be well established. In this paper, we focus on the stylized facts of international business cycles. We use the generalized method of moments and quarterly...

Multi-country models have not been very successful in replicating important features of the international transmission of business cycles. Standard models predict cross-country correlations of output and consumption which are respectively too low and too high. In this paper, we build a...

We provide a new structural interpretation of the relationship between the slope of the term structure of interest rates and macroeconomic fundamentals. We first adopt an agnostic identification approach that allows us to identify the shocks that explain most of the movements in the slope. We...

We study the restrictions implied by optimal policy DSGE models for the volatility of observable endogenous variables. Our approach uses a parametric family of singular models to discriminate which volatility sample outcomes have zero probability of being generated by an optimal policy. Thus the...

This paper studies a dynamic-optimizing model of a semi-small open economy with sticky nominal prices and wages. the model exhibits exchange rate overshooting in response to money supply shocks. the predicted variability of nominal and real exchange rates is roughly consistent with that of G7...

Survey evidence shows that the main reason why .rms keep prices stable is that they are concerned about losing customers or market share. We construct a model in which .rms care about the size of their customer base. Firms and customers form long-term relationships because consumers incur costs...

Price rigidity is often modeled by assuming that firms face a fixed cost of price change. However, in surveys, firms report that the main reason they wish to keep prices stable is for fear of antagonizing customers. Moreover, marketing studies show that most consumers engage in very little...

This paper studies the proposition that an inflation bias can arise in a setup where a central banker with asymmetric preferences targets the natural unemloyment rate.
