Despite impressive growth in derivatives markets around the world, there is considerable heterogeneity in the degree of development across countries. In Latin America, derivatives markets in Chile lag far behind those in Brazil and Argentina. What accounts for these differences? The analytical...

In this article, we formulate a time-scale decomposition of an international version of the CAPM that accounts for both market and exchange-rate risk. In addition, we derive an analytical formula for time-scale value at risk and marginal value at risk (VaR) of a portfolio. We apply our...

A random-effect model is devised with individual- and time-specific components for uncensored data, based on a specification for censored data developed by Anderson (1985) and extended by Kim and Maddala (1992). In addition, specification tests are devised that allow one to choose between the...

This paper focuses on return spillovers in stock markets at different time scales using wavelet analysis. We look at eight stock indices that comprise the G7 countries, emerging Asia, Western Europe, Eastern Europe and the Middle East, the emerging Far East, Latin America, North America, and the...

This paper analyzes the effect of recent political conflicts in the Middle East on stock markets worldwide. In particular, it studies how political instabilityâmainly due to the war in Iraqâhas affected the long-term volatility of stock markets, using two approaches, Inclan and Tiao's (1994)...

In this article, we formulate a time-scale decomposition of an international version of the CAPM that accounts for both market and exchange rate risk. In addition, we derive an analytical formula for time-scale value at risk (VaR) and time-scale marginal VaR of a portfolio. We apply our...

Based on weekly data of the Dow Jones Country Titans, the CBT-municipal bond, spot and futures prices of commodities for the period 1992-2005, we analyze the implications for portfolio management of accounting for conditional heteroskedasticity and structural breaks in long-term volatility. In...
