Multivariate decisions with unknown price vector
Abstract
We consider a class of decision makers who have to choose among different random bundles of commodities. It is assumed that they maximize expected utility, and their utility functions depend only on the monetary value of the bundles of commodities. Stochastic dominance conditions are provided when the price vector is assumed unknown. Risk aversion and constraints on the price vectors are considered as particular cases. The results are compared with other approaches to multivariate decisions.
