Expected Utility Theory

The most famous example of such a theory was published by von Neumann and Morgenstern (1944) (VNM). They proposed it as a “normative” theory of behaviour. That is, classical utility theory as a “normative” theory of behaviour.

Probability Distributions and Expected Value

Probability Distributions and Expected Value. In previous chapters, our emphasis was on the probability of individual outcomes. This chapter develops models for distributions that show the probabilities for all possible outcomes of an experiment. Random Variable (X).

Expected Value

Expected Value. Section 3.5. Definition. Let’s say that a game gives payoffs a 1 , a 2 ,…, a n with probabilities p 1 , p 2 ,… p n . The expected value ( or expectation) E of this game is E = a 1 p 1 + a 2 p 2 + … + a n p n . Think of expected value as a long term average.
