Under a comonotonicity assumption between aggregate dividends and the market portfolio, the CCAPM formula becomes more tractable and more easily testable. In this paper, we provide theoretical justifications for such an assumption.

This article proposes a mean-variance optimization and portfolio frontier analysis of energy risk management with … the CAPM. These results reveal that carbon, gas, coal and bond assets share the best properties for composing an optimal … management, as the carbon market constitutes a segmented commodity market with specific risk factors linked to the EU Commission …

Farm risk management for income stabilization is on-going issue. An applied work has been performed to measure farm … risk using a stochastic model. Risk management tools, with symmetric as well as asymmetric impacts, are then tested and … compared through ad hoc statistics. Normal farm business risk can be efficiently managed using a precautionary saving provision …

We present a new recursive algorithm to construct vine copulas based on an underlying tree structure. This new structure is interesting to compute multivariate distributions for dependent random variables. We proove the asymptotic normality of the vine copula parameter estimator and show that...

Si la littérature, reconnait la vulnérabilité des Supply Chains Internationales et les risques auxquels elles sont exposées, il est cependant étonnant, de constater le manque de cadres conceptuels et de résultats empiriques qui puissent fournir une compréhension claire du concept de...
