Abstract: | Proofs of compatibility of the expected utility and μ/σ approaches to incorporating uncertainty in decision making exist for
at least some utility functions and location–scale distributions. But there are severe constraints and it is desirable to
investigate compatibility more widely. We do so for the class of distributions that are transformable to location–scale form
by concave transformation and where the utility functions remain concave under transformation. The class is important, containing
distributions such as the lognormal and Pareto, usually considered more appropriate for modelling income or wealth than those
in the location–scale family.
We are grateful to Jack Meyer for very helpful comments and discussions and also to an anonymous referee for useful remarks. |
