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...

Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit … it. One of them is the existence of systemic risk that affects all the policies at the same time. We introduce here a … probabilistic approach to examine the consequences of its presence on the risk loading of the premium of a portfolio of insurance …
