This axiom implies that the a minor change in the probabilities of state of the nature should not induce a modification of the order of preference of the participant: In words, preference inequalities are preserved when the initial two lotteries are mixed in a given proportion with a third lottery. Although Daniel Bernouli (1738) proposed the theory of expected utility as a basis for decision-making under risk, using a logarithmic utility for wealth, his use of expected-value operation in conjunction with a utility function is largely ignored for 200 years until it re-emerged in modern financial economics, behavioral economics, and information theory. But Bernoulli found that wealth does not have a linear relationship to the utility that is related to wealth. because investors rarely behave according to the assumptions made in traditional financial and economic theory.

A brief description of the experiment undertaken by Allais is here stated: Here, the majority of the participants choose certain amount in option 1, though the expected grain from lottery 2 is higher (1 140 000 against the certain amount 1 000 000 in the first choice). tanveer• 2 år siden.

Expected utility (EU) theory remains the dominant approach for modeling risky decision-making and has been considered the major paradigm in decision making since World War II, being used predictively in economics and finance, prescriptively in management science, and descriptively in psychology ().Furthermore, EU is the common economic approach for addressing public policy … • Individuals should act in a particular way when they do decision making under the uncertainty.
