What is the expected utility theorem?

In economics, game theory, and decision theory, the expected utility hypothesis—concerning people's preferences with regard to choices that have uncertain outcomes (gambles)—states that the subjective value associated with an individual's gamble is the statistical expectation of that individual's valuations of the outcomes of that gamble, where these valuations may differ from the ...

**expected utility hypothesis**is the**hypothesis**in economics that the**utility**of an agent facing uncertainty is calculated by considering**utility**in each possible state and constructing a weighted average. The weights are the agent's estimate of the probability of each state. The**expected utility**is thus an expectation in terms of probability ...**Utility**function. Consider a set of alternatives facing an individual, and over which the individual has a preference ordering. A**utility**function is able to represent those preferences if it is possible to assign a real number to each alternative, in such a way that alternative a is assigned a number greater than alternative b if, and only if, the individual prefers alternative a to ...Apr 26, 2019 ·
