This paper uses a DSGE model of two small open economies to explain certain features of real exchange rate cyclical fluctuations in countries with fixed and flexible exchange rates, focusing on the role of traded and non-traded goods prices. In particular, the model illustrates why the relative...

The purchasing power parity (PPP) puzzle refers to the inability to reconcile the high short-run volatility of exchange rates with the glacial speed at which deviations from parity seem to damp out. Despite this, there is strong evidence of the long-run relationship between exchange rates and...

Half-lives are summary measures of persistence, and are usually characterized from impulse response functions (IRFs) of univariate time series models. Two issues which occur with half-life characterization in multivariate time series are IRFs become conditional on specific shocks and are often...

This paper studies the effect of transport infrastructure on the real exchange rate (RER) and reaches two relatively strong conclusions. First, while the list of robust determinants of the RER is not long, transport infrastructure belongs to that list. Many other potential determinants proposed...

International real business cycle (IRBC) models predict a real exchange rate volatility that is much lower than the levels observed in the data. In this paper, we build a two-country IRBC model with both a traded and a non-traded goods sector, and calibrate it to UK-euro area (EA) data. We...

The standard argument for abstracting from capital accumulation in sticky-price macro models is based on their short-run focus: over this horizon, capital does not move much. This argument is more problematic in the context of real exchange rate (RER) dynamics, which are very persistent. In this...

The half-life of deviations from purchasing power parity (PPP) plays a central role in the ongoing debate about the ability of macroeconomic models to account for the time series behavior of the real exchange rate. The main contribution of this paper is a general framework in which alternative...

This paper analyzes the dynamics of risk premia, real exchange rates and portfolio movements in a two-country, two-good, two-bond model. We use an asymmetric set-up in the model, where one of the countries is emerging and the other one is developed and both countries issue bonds in domestic...
