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...

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 the Weighted Average Cost of Capital (WACC) applied to the free cash flow (FCF), we assume that the cost of debt is the market, unsubsidized rate. With debt at the market rate and perfect capital markets, debt only creates value in the presence of taxes through the tax shield. In some cases,...

In this article, we test for the presence of structural breaks in volatility by two alternative approaches: the Iterative Cumulative Sum of Squares (ICSS) algorithm and wavelet analysis. Specifically, we look at the effect of the outbreak of the Asian crisis and the terrorist attacks of...

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...

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...

This paper considers the existence of a bank lending channel in Chile. Toward that, we collect a data sample of nineteen banks that operated in Chile over January 1999- December 2002. In that period, banks primarily offered loans to firms in the manufacturing and the financial-services sectors...
