We use volatility impulse response analysis estimated from the bivariate GARCH-BEKK model to quantify the size and the persistence of different types of oil price shocks on stock return volatility and the covariance between oil price changes and stock returns for a wide range of net...

In dieser Untersuchung wird gezeigt, wie neuere ökonometrische Verfahren zur Modellierung und Prognose von Volatilitäten auf Aktienmärkten eingesetzt werden können. Hierzu werden verschiedene Varianten aus der Klasse der ARCH Modelle und das Markov-Mischungsmodell herangezogen. Die...
