Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity of between three to five years. However, least squares-based estimates of half-lives are biased downward. Accordingly, we...

This paper studies the role of an increase in foreign exchange reserves in reducing currency volatility for emerging market countries. The study employs a panel of 28 countries over the period 1986-2002. Several control variables are introduced in the regressions to account for other factors...

This paper reviews recent advances in the specification and estimation of Bayesian Vector Autoregressive models (BVARs). After describing the Bayesian principle of estimation, we first present the methodology originally developed by Litterman (1986) and Doan et al. (1984) and review alternative...

This paper outlines a way to estimate transition matrices for use in credit risk modeling with a decades-old methodology that uses aggregate proportions data. This methodology is ideal for credit-risk applications where there is a paucity of data on changes in credit quality, especially at an...

This paper analyzes broad money demand (M2) in Guyana from January 1990 to September 1999; a period marked by deep transformations aimed at shifting Guyana from a centralized to a market economy. The paper develops a stable error-correction model based on a long-run cointegrating vector of money...

An influential theoretical literature has observed that economic diversification can reduce risk and increase financial development. But causality operates in both directions, as a well functioning financial system can enable a society to invest in more productive but risky projects, thereby...

Using the ARFIMA-FIGARCH model, this paper studies the efficiency of the Japanese equity market by examining the statistical properties of the return and volatility of the Nikkei 225. It shows that both follow a long range dependence, which stands against the efficient market hypothesis (EMH)....

Government spending plays a critical role in protecting and enforcing rights and civil liberties. Empirical evidence for a sample of industrial and developing countries shows that government expenditures on defense, law and order, social security, education, and health care are associated with...

This paper examines volatility spillovers from mature to emerging stock markets and tests for changes in the transmission mechanism-contagion-during turbulences in mature markets. Tri-variate GARCH-BEKK models of returns in global (mature), regional, and local markets are estimated for 41...

The existing literature suggests a number of alternative methods to test for the presence of contagion during financial market crises. This paper reviews those methods and shows how they are related in a unified framework. A number of extensions are also suggested that allow for multivariate...
