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...

This paper proposes a novel international transmission mechanism based on the assumption of deep habits. The term deep habits stands for a preference specification according to which consumers form habits on a good-by-good basis. Under deep habits, firms face more elastic demand functions in...

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...

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...

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 presents a model of international portfolios with real exchange rate and non financial risks that accounts for observed levels of equity home bias. A key feature is that investors can trade equities as well as domestic and foreign real bonds. Bonds matter: in equilibrium, investors...

This paper presents a simple model of currency crises, which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities. The possibility of multiple equilibria, including a ‘currency crisis’ equilibrium with low output...

This paper improves upon the recently developed literature on exits from fixed exchange rate regimes in three ways: 1) It allows for two indicators for post-exit macroeconomic conditions, the change in the exchange rate and the change in the output gap; 2) it tests whether the distinction...

Fluctuations in GDP are more synchronized internationally than fluctuations in consumption, and they remain so even between financially-integrated economies, where the ranking should in theory be the reverse. This Paper shows this happens because correlations in GDP fluctuations rise with...
