Models of “contagion” rely on market imperfections to explain why adverse shocks in one asset market might be associated with asset sales in many unrelated markets. This paper demonstrates that contagion can be explained with basic portfolio theory without recourse to market imperfections....

We examine the mean-reverting properties of real exchange rates, by comparing the unit root properties of a group of international real exchange rates with two groups of intra-national real exchange rates. Strikingly, we find that while the international real rates taken as a group appear...

This paper establishes that output volatility and the size of output drops have declined across all countries over the past three decades, but remain considerably higher in developing countries than in industrial countries. The paper employs a Bayesian latent dynamic factor model to decompose...

Oil funds have become increasingly popular in oil exporting countries during the recent surge in oil prices. However, the literature on the contribution is small, tends to focus narrowly on their fiscal benefits, and concludes that they are redundant of such funds-in other words, that well...

The influential work of Ramey and Ramey (1995) highlighted an empirical relationship that has now come to be regarded as conventional wisdom-that output volatility and growth are negatively correlated. We reexamine this relationship in the context of globalization-a term typically used to...

A recent study by Grilli and Kaminsky (1991) argues that real exchange rate (RER) behavior is likely to be dependent on the particular historical period rather than on the nominal exchange rate arrangement itself. This paper reexamines RER behavior using alternative data sets, as well as...

This paper builds on the ARCH approach for modeling distributions with time-varying conditional variance by using the generalized Student t distribution. The distribution offers flexibility in modeling both leptokurtosis and asymmetry (characteristics seen in high-frequency financial time series...
