The empirical literature on nominal exchange rates shows that the current exchange rate is often a better predictor of future exchange rates than a linear combination of macroeconomic fundamentals. This result is behind the famous Meese-Rogoff puzzle. In this paper we evaluate whether parameter...

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...

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 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...

In this Paper we present an overview of a number of issues relating to the equilibrium exchange rates of the new EU member states from Central and Eastern Europe. In particular, we present a critical overview of the various methods available for calculating equilibrium exchange rates and discuss...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

Central banks can go broke and have done so, although mainly in developing countries. The conventional balance sheet of the central bank is uninformative about the financial resources it has at its disposal and about its ability to act as an effective lender of last resort and market marker of...

This paper analyzes quantitatively the extent to which there is overborrowing (i.e., inefficient borrowing) in a business cycle model for emerging market economies with production and an occasionally binding credit constraint. The main finding of the analysis is that overborrowing is not a...
