Relationships Between Archimedean Copulas and Morgenstern Utility Functions

Spreeuw, J. (2010). Relationships Between Archimedean Copulas and Morgenstern Utility Functions. Paper presented at the Copula Theory and Its Applications, 25-26 September 2009, Warsaw.

Abstract

The (additive) generator of an Archimedean copula is a strictly decreasing and convexfunction, while Morgenstern utility functions (applying to risk aversion decision makers) arenondecreasing and concave. In this presentation, relationships between generators and utilityfunctions are established. For some well known Archimedean copula families, links betweenthe generator and the corresponding utility function are demonstrated.Some new copulafamilies are derived from classes of utility functions which appeared in the literature, andtheir properties are discussed. It is shown how dependence properties of an Archimedeancopula translate into properties of the utility function from whichthey are constructed.
