Maxmin expected utility through statewise combinations

Abstract We provide an axiomatic foundation for a maxmin expected utility over a set of priors (MMEU) decision rule in an environment where the elements of choice are Savage acts. The key axioms are stated using statewise combinations as in Gul [Gul, F., 1992. Savage’s theorem with a finite number of states. Journal of Economic Theory 57, 99–100].
