Measuring financial asset return and volatilty spillovers, with application to global equity markets
(2008)
We provide a simple and intuitive measure of interdependence of asset returns and/or volatilities. In particular, we formulate and examine precise and separate measures of return spillovers and volatility spillovers. Our framework facilitates study of both non-crisis and crisis episodes, including trends and bursts in spillovers, and both turn out to be empirically important. In particular, in an analysis of nineteen global equity markets from the early 1990s to the present, we find striking evidence of divergent behavior in the dynamics of return spillovers vs. volatility spillovers: Return spillovers display a gently increasing trend but no bursts, whereas volatility spillovers display no trend but clear bursts.

Die vorliegende empirische Studie analysiert die Vertragsgestaltung zwischen Investoren und europäischen Venture Capital-Fonds. Im Zentrum steht die Analyse der Vergütung des Fondsmanagements sowie der zum Einsatz kommenden Vertragsklauseln. Deren Ausgestaltung ist entscheidend für die Überwindung der Prinzipal-Agenten-Beziehung innewohnenden Agency-Probleme. Hierzu werden 122 Fondsprospekte sowie 46 Gesellschafterverträge von europäischen Venture Capital-Fonds ausgewertet, die in den Jahren 1996 bis 2001, der ersten großen Boomphase des europäischen Venture Capital-Marktes, aufgelegt wurden. Während die jährliche Vergütung des Fondsmanagements auf den ersten Blick sehr standardisiert erscheint, ergeben sich bei einer Barwertbetrachtung aller zu leistenden Management Fees über die gesamte Fondslaufzeit deutliche Anzeichen für Preisdifferenzierung. In Bezug auf den Einsatz von Vertragsklauseln kann eine Zunahme im Zeitablauf und mithin eine zunehmende Komplexität des Vertragsdesigns festgestellt werden. Vor dem Hintergrund der Erfahrungen aus dem US-amerikanischen Venture Capital-Markt kann diese Entwicklung jedoch noch nicht als abgeschlossen gelten. Der europäische Markt bewegt sich in Bezug auf die Verwendung vertraglicher Restriktionen auf dem Niveau, das in den USA bereits Anfang der neunziger Jahre erreicht war.
According to disposition effect theory, people hold losing investments too long. However, many investors eventually sell at a loss, and little is known about which psychological factors contribute to these capitulation decisions. This study integrates prospect theory, utility maximization theory, and theory on reference point adaptation to argue that the combination of a negative expectation about an investment’s future performance and a low level of adaptation to previous losses leads to a greater capitulation probability. The test of this hypothesis in a dynamic experimental setting reveals that a larger total loss and longer time spent in a losing position lead to downward adaptations of the reference point. Negative expectations about future investment performance lead to a greater capitulation probability. Consistent with the theoretical framework, empirical evidence supports the relevance of the interaction between adaptation and expectation as a determinant of capitulation decisions.

The use of GARCH models with stable Paretian innovations in financial modeling has been recently suggested in the literature. This class of processes is attractive because it allows for conditional skewness and leptokurtosis of financial returns without ruling out normality. This contribution illustrates their usefulness in predicting the downside risk of financial assets in the context of modeling foreign exchange-rates and demonstrates their superiority over use of normal or Student´s t GARCH models.
