We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We study the case of constant relative risk aversion (of some order) to investigate on different equivalence relations in order to determine the, possibly infinite, number of equivalence...

Abstracting from self-protection and self-insurance e ects of export produc-tion choices, exporting rms usually have access to a number of risk sharingmarkets that have an efficient risk management role. Two of the most strikingresults achieved from the existence of risk sharing markets are the...

We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We apply a general view of constant relative risk aversion to investigate on different equivalence relations. Then we compare our results with standard applications in economics and finance.
