The international welfare effects of a country's monetary policy shocks have been controversial in the literature. While a unilateral monetary expansion increases the production efficiency in each country, it affects terms of trade in favor of one country against another depending on the...

We lay out an empirical and a theoretical model to analyze the effects of non-fundamental exchange rate volatility on economic activity and welfare. In the first part of the paper, the GARCH-SVAR model is applied to measure empirically the effect of the conditional exogenous exchange rate...

International spillovers and exchange rate dynamics are examined in a two-country dynamic optimizing model that allows for home-product bias in consumption patterns: at given relative prices the ratio of home goods consumed to foreign goods consumed is higher in the home country. The setup nests...

The main tenet of the New Keynesian (NK) paradigm is that price dispersion caused by nominal price stickiness is the primary source of allocative inefficiency. This study empirically evaluates the welfare implications of NK models by observing how internal and external price dispersion responds...

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these...

This paper studies welfare gains from disinflation in the presence of currency substitution. A distinctive small open economy model with currency substitution and intermediated working capital is constructed for this objective. It is found that welfare gains from disinflation are higher when the...

This paper examines the relationship between the exchange rate regime and trade flows using a general equilibrium model based on Bacchetta and van Wincoop (AER, 2000). We show that in general the link between trade and the exchange rate regime is ambiguous and that it depends in particular on...

We develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare. An important feature of the model is deviations from purchasing power parity, caused by rigid price setting in buyers' currency. We find the following. First, exchange rate...
