Abstract: | We consider the problem of extending a (complete) order over a set to its power set. The extension axioms we consider generate
orderings over sets according to their expected utilities induced by some assignment of utilities over alternatives and probability
distributions over sets. The model we propose gives a general and unified exposition of expected utility consistent extensions
whilst it allows to emphasize various subtleties, the effects of which seem to be underestimated – particularly in the literature
on strategy-proof social choice correspondences.
