This paper suggests a goodness-of-fit test for parametric families of Archimedean copulas for high dimensional distributions. The test statistic is based on the classical chi-square-statistic but has a nonstandard asymptotic distribution. Monte-Carlo simulations show that the test keeps the...

This study proposes a novel framework for the joint modelling of commodity forward curves. Its key contribution is twofold. First, dynamic correlation models are applied in this context as part of the modelling scheme. Second, we introduce a family of dynamic conditional correlation models based...

We introduce a new discounted cash flow model which integrates the diversification effect of multi-business firms. We face two challenges. One is examining how different degrees of diversification can affect firm value due to risk reduction, and the other is modeling segment-specific cash flows...
