On the risk-aversion comparability of state-dependent utility functions
This paper proposes a criterion for the partial ordering of state- dependent utility functions according to risk attitude. It is proved that if two or more state-dependent utility functions satisfy a global condition on cross-state marginal utilities on the set of sure wealths, then they can be compared by means of Arrow-Pratt measures of risk aversion. This criterion is contrasted with that proposed by \textit{E. Karni} [Int. Econ. Rev. 24, 637-647 (1983; Zbl 0524.90010)].
