Health Economics

  • (written as Ambiguity)

    A term used by decision and game theorists in the context of certain kinds of decisions under uncertainty that, from the perspective of subjective utility theory, display a kind of bias in the human psyche. This poses problems for users of expected utility theory.

    Suppose there are two urns, each containing 100 balls, which are either red or black. One urn has 50 red and 50 black balls. The proportion of red and black balls in the other urn is unknown. You can draw one ball from one of the urns, without looking, and if you draw a red ball you win a hundred dollars. Which urn would you choose Most people choose the 50-50 urn, even though, if we take the view that there are insufficient reasons for discriminating between the two urns, there is no higher probability of getting a red than by picking from the other urn. When offered 100 dollars for a black ball, they also choose the 50-50 urn. They seem to be averse to the 'ambiguity' represented by the other urn and strongly prefer what is apparently clear-cut. This is also known as the Ellsberg paradox (Ellsberg, 1961).
