It is accepted that standard macroeconomic variables are not capable of predicting ex ante the majority of short term changes in exchange rates. Lettau and Ludvigson (2001) find that fluctuations in the common long-term trend in consumption, asset wealth, and labour income (hereby,...

We develop a small open economy general equilibrium model with sticky prices and partial dollarization -- a situation where both domestic and foreign currencies coexist. We derive a tractable representation of the model in terms of domestic inflation and the output gap in which a trade-off,...

How important are nontradable goods and distribution costs to explain real exchange rate dynamics? We answer this question by estimating a general equilibrium model with intermediate and final tradable and nontradable goods. We find that the estimated model can match characteristics of the data...

In this paper, we develop and estimate a dynamic stochastic, general-equilibrium New Keynesian model with partial dollarization. Bayesian techniques and Peruvian data are used to evaluate two forms of dollarization: currency substitution (CS) and price dollarization (PD). The empirical results...

In the data, Real Exchange Rates (RERs) tend to move in opposite directions with respect to the relative consumption across countries. Chari <italic>et al</italic>. (2002) refer to the inability of models to replicate the previous stylized fact as the consumption-RER anomaly. In this article, it is shown that an...

We study how monetary policy may affect determinacy and expectational stability (E-stability) of rational expectations equilibrium when the cost channel of monetary policy matters. Focusing on instrumental Taylor-type rules and optimal target rules, we show that standard policies can induce...

Several theoretical contributions using two-country models have combined alternative forms of pricing under nominal rigidities with different asset market structures to explain real exchange rate dynamics. We estimate a two-country model using data for the United States and the Euro Area, and...

A puzzle in international macroeconomics is that real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. This paper provides evidence that TFP processes for the U.S. and the "rest of the world" are characterized by a vector...

The link between inflation and inflation uncertainty is evaluated using Peruvian data, in a context of changing monetary policies because of regime shifts. A Markov regime-switching heteroskedasticity model that includes unobserved components is used. The model shows how periods of high (low)...
