The Predictive Utility of Generalized Expected Utility Theories.

Recent experimental choice studies compare expected utility with competing theories of decision-making under risk. Formal tests used to judge the theories usually count the number of consistent responses, ignoring systematic variation in inconsistent responses. A maximum-likelihood estimation method is developed that extracts more information from the data and enables one to judge the predictive utility--fit and parsimony--of utility theories. Analyses of twenty-three data sets suggest a menu of theories that sacrifice the least parsimony for the biggest improvement in fit. The menu is mixed fanning, prospect theory, expected utility, and expected value. Copyright 1994 by The Econometric Society.
