Is there a gain to explicitly modelling extremes? A risk management analysis

When risk managers make decisions, they need them to be based upon reliable measures. Strong assumptions are often made to simplify the risk estimation process and there has to be a trade-off between ease of estimate and accuracy. In this paper, “Is there a gain to explicitly modelling extremes? A risk measurement analysis”, Jean-Christophe Meyfredi of the Edhec Risk and Asset Management Research Centre develops a copula-based approach in order to estimate the Value-at-Risk of portfolios containing financial assets. He proposes a survival copula, the Heavy Right Tail copula, which could solve many difficulties that risk managers currently have to face.

About EDHEC-Risk Climate Impact Institute

Marking the priority assigned by the School to sustainability issues and building on its research programmes exploring the relationships between climate change and finance, EDHEC-Risk Institute became EDHEC-Risk Climate Impact Institute in October 2022. The Institute's mission is to help private and public decision-makers manage climate-related financial risks and make the best use of the financial tools available to transition to low-emission and climate-resilient economies. The Institute’s research programmes explore the relationships between climate change and finance and our key ambition is to become a leading academic reference point for long-term investors, helping them to manage the asset-pricing implications of climate change as well as mitigation and adaptation efforts.
