I develop a two-country New Keynesian model with capital accumulation and incomplete international asset markets that provides novel insights on the effect that imperfect international risk-sharing has on international business cycles and RER dynamics. I find that business cycles appear similar...

This technical note is developed as a mathematical companion to the paper ‘The Real Exchange Rate in Sticky Price Models: Does Investment Matter?' (GMPI working paper no.17). It contains three basic calculations. First, we derive the equilibrium conditions of the model. Second, we compute the...

This paper re-examines the ability of sticky-price models to generate volatile and persistent real exchange rates. We use a DSGE framework with pricing-to-market akin to those in Chari, et al. (2002) and Steinsson (2008) to illustrate the link between real exchange rate dynamics and what the...

This paper introduces the R package exuber for testing and date-stamping periods of mildly explosive dynamics (exuberance) in time series. The package computes test statistics for the supremum ADF test (SADF) of Phillips, Wu and Yu (2011), the generalized SADF (GSADF) of Phillips, Shi and Yu...

This paper re-examines the ability of sticky-price models to generate volatile and persistent real exchange rates. We use a DSGE framework with pricing to market to illustrate the link between real exchange rate dynamics and what the model assumes about physical capital. We show that adding...

Data for the U.S. and the Euro-area during the post-Bretton Woods period shows that nominal and real exchange rates are more volatile than consumption, very persistent, and highly correlated with each other. Standard models with nominal rigidities match reasonably well the volatility and...
