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...

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...

In this Paper we assess the progress made by the profession in understanding whether and how exchange rate intervention works. To this end, we review the theory and evidence on official intervention, concentrating primarily on work published within the last decade or so. Our reading of the...

The Paper considers alternative exchange rate regimes for the 10 East European accession candidates, both prior to EU accession and during the period following EU accession but prior to EMU membership. We conclude that from an economic point of view, EMU membership should be as early as...

This paper addresses the consumption-real exchange rate anomaly. International real business cycle models based on complete financial markets predict a unitary correlation between the real exchange rate and the ratio of home to foreign consumption when subjected to supply side shocks. In the...

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 behaviour of the real exchange rate. The main contribution of this paper is a general framework in which alternative...

Originally propounded by the 16th-century scholars of the University of Salamanca, the concept of purchasing power parity (PPP) was revived in the interwar period in the context of the debate concerning the appropriate level at which to re-establish international exchange rate parities. Broadly...

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...

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...

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...
