Copula Phase Transitions Report

Research Projects – Risk Management


The Casualty Actuarial Society, Canadian Institute of Actuaries, and Society of Actuaries' Joint Risk Management Research Team is pleased to make available a research report on phase transitions and copulas. This report, authored by Michael A. Ekhaus of Gibraltar Analytical, LLC, has two primary objectives. The first is to incorporate phase transitions into a copula framework, and the second is to apply this to calculate the probability of defaulting in the context of a portfolio of correlated mortgages when acontagion effect exists.
