Webb7 apr. 2016 · Standard Bayesian decision theory tells us to maximize the expected value of our actions. a For instance, suppose we see a number of kittens stuck in trees, and we decide that saving some number n of kittens is n times as good as saving one kitten. Webb8 aug. 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.)
WebbThat is, a consumer with concave value function prefers the average outcome to the random outcome. This is illustrated in Figure 13.8 "Expected utility and certainty equivalents".There are two possible outcomes: x 1 and x 2.The value x 1 occurs with probability π, and x 2 with probability 1 – π.This means that the average or expected … Webb#beCrazy instead of "Be hungry, be foolish".

Webbexpected utility theory. However, in order to accomodate the effects described in the first part of the paper, we are compelled to assume that values are attached to changes rather than to final states, and that decision weights do not coincide with stated probabilities. These departures from expected utility theory must lead to
