We propose an exchange rate model that can explain both the observed volatility and the persistence of real and nominal exchange rate movements and thus in some measure resolves Rogoff’s (1996) purchasing power parity puzzle. Our analysis reconciles the well-known difficulties in beating the...

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country’s net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between...

In this Paper we test empirically the validity of the law of one price using data for five major bilateral US dollar exchange rates and nine goods sectors during the recent floating exchange rate regime since the early 1970s. Using threshold autoregressive models, we find strong evidence of...

Real exchange rates appear to present a specific behaviour in the early phase of transition: they are largely unaffected by nominal exchange rate movements and exhibit trend appreciation. The model presented here describes the transition process as the emergence of two new (traded and non-traded...

The results of this paper complement the recent findings of real exchange rates as stationary processes. The standard procedure of applying a battery of unit root tests can be problematic since the tests are sensitive to the specifics of the time-series process. The novelty of the approach we...

This paper studies sharp reductions in current account deficits and large exchange rate depreciations in low- and middle-income countries. It examines which factors help predict the occurrence of a reversal or a currency crisis, and how these events affect macroeconomic performance. It finds...

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of ‘commodity points’ – thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in...

In mid-2008, the real effective exchange rate of the dollar was close to its minimum level for the past 4 decades. At the same time, however, the U.S. trade and current account deficits remain large and, absent a significant correction in coming years, would contribute to a further accumulation...

We assume that individuals can fully insure themselves against cross-country shocks, but not against individual-specific shocks. We consider two particular models of limited risk-sharing: domestically incomplete markets (DI) and private information-Pareto optimal (PIPO) risk-sharing. For each...

We fit nonlinearly mean-reverting models to real dollar exchange rates over the post-Bretton Woods period, consistent with a theoretical literature on transaction costs in international arbitrage. The half lives of real exchange rate shocks, calculated through Monte Carlo integration, imply...
