The expected utility hypothesis is a foundational assumption in mathematical economics concerning decision making under uncertainty. It postulates that rational agents maximize utility, meaning the subjective desirability of their actions.
Aug 8, 2014 · Expected utility theory provides a way of ranking the acts according to how choiceworthy they are: the higher the expected utility, the better it is to choose the act. (It is therefore best to choose the act with the highest expected utility—or one of them, in the event that several acts are tied.)
Two basic elements of expected utility theory: consequences (or outcomes) and lotteries. Consequences. Finite set C of consequences. Consequences are what the decision-maker ultimately cares about. Example: “I get pneumonia, my health insurance company covers most of the costs, but I have to pay a $500 deductible.”
Written by CFI Team. What is Expected Utility? Expected utility is a theory in economics that estimates the utility of an action when the outcome is uncertain. It advises choosing the action or event with the maximum expected utility.
The theorem is the basis for expected utility theory. In 1947, John von Neumann and Oskar Morgenstern proved that any individual whose preferences satisfied four axioms has a utility function ; [1] such an individual's preferences can be represented on an interval scale and the individual will always prefer actions that maximize expected utility.
von Neumann and Morgenstern proved that, as long as all the preference axioms hold, then a utility function exists, and it satisfies the expected utility property. See here for a complete proof of the Expected Utility Theorem.
