Learn how to calculate it and why it’s important to economists and businesses. von Neumann and Morgenstern proved that, as long as all the preference axioms hold, then a utility function exists, and it satisfies the expected utility property. The prescription to select a portfolio that maximizes an investor’s expected utility is hardly new. Recall that a “degenerate” lottery yields only one consequence with probability 1; the probabilities of all other consequences are zero for this lottery. It is a theory of moral choice, but whether rationality requires us to do what is morally best is up for debate. Centuries after Bernoulli, von Neumann and Morgenstern would strengthen the case for maximizing the expected value of some kind of utility function, though not necessarily Bernoulli’s utility. Likewise, Expected utility shows us the utility that is expected out of a lottery with two or more possibilities. The following statements are equivalent: (i) Á on ΔpCq satisfies A1, A2 and A3.
