    In economics, individuals are assumed to rank lotteries according to a rational system of preferences, although it is now accepted that people make irrational choices systematically.

  3. Expected utility hypothesis - Wikipedia

    en.wikipedia.org/wiki/Expected_utility_hypothesis

    The theory of subjective expected utility combines two concepts: first, a personal utility function, and second, a personal probability distribution (usually based on Bayesian probability theory). This theoretical model has been known for its clear and elegant structure and is considered by some researchers to be "the most brilliant axiomatic ...

  7. Random utility model - Wikipedia

    en.wikipedia.org/wiki/Random_utility_model

    There is a positive probability that an agent will prefer a to b, b to c, and c to a. The maximum likelihood estimator - which is the Kemeny–Young method - is hard to compute (it is Θ 2 P {\displaystyle \Theta _{2}^{P}} -complete).

  8. Von Neumann–Morgenstern utility theorem - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann–Morgenstern...

    The lottery ′ is, in effect, a lottery in which the best outcome is won with probability (), and the worst outcome otherwise. Hence, if u ( M ) > u ( L ) {\displaystyle u(M)>u(L)} , a rational decision maker would prefer the lottery M {\displaystyle M} over the lottery L {\displaystyle L} , because it gives him a larger chance to win the best ...

  9. Dutch book theorems - Wikipedia

    en.wikipedia.org/wiki/Dutch_book_theorems

    In economics, the classic example of a situation in which a consumer X can be Dutch-booked is if they have intransitive preferences. Classical economic theory assumes that preferences are transitive: if someone thinks A is better than B and B is better than C, then they must think A is better than C. Moreover, there cannot be any "cycles" of ...
