We use multivariate regime switching vector autoregressive models to characterize the time-varyinglinkages among the Irish stock market, one of the top world performers of the 1990s, and the US andUK stock markets. We ¯nd that two regimes, characterized as bear and bull states, are required...

The viability of international diversification involves balancing benefits and costs.This balance hinges on the degree of asset dependence. In light of theoretical researchlinking diversification and dependence, we examine international diversification usingtwo measures of dependence:...

International diversification has costs and benefits, depending on the degree of assetdependence. In light of theoretical research linking diversification and dependence, weexamine international diversification with two dependence measures: correlations andextreme dependence. We document several...

This paper analyzes the relation between correlation risk and the cross-section of hedge fund returns.Legal framework and investment mandate imply that hedge funds can be severely exposed tocorrelation risk: Hedge funds ability to enter long-short positions can be useful to reduce marketbeta,...

In this paper we solve an intertemporal portfolio problem with correlation risk, using a new approach for the simultaneous modeling of stochastic correlation and volatility. The solutions of the model are in closed form and include an optimal portfolio demand for hedging correlation risk. We...

Starting from the Merton framework for firm defaults, we provide the analytics and robustness of the relationship between default correlations. We show that loans with higher default probabilities will not only have higher variances but also higher correlations between loans. As a consequence,...

Vorliegendes Arbeitspapier analysiert die Einflüsse intertemporaler Renditezusammenhänge und fester Startwerte in Vektorautoregressions-(VAR-) Modellen für stetige Renditen anhand des Vergleichs mit einem statischen Random-Walk-Modell.
