Expectation and Variation in Multi-period Decisions

Econometrica, 1989, vol. 57, issue 5, 1153-69

Abstract: This paper suggests an alternative to the weighted average utility maximization as a criterion for multiperiod decisions. A weakened version of Savage's sure-thing principle, imposed on Schmeidler's nonadditive measure model, yields decision rules which involve a weighted average of utility, as well as a weighted average of the utility's variation between each two consecutive periods. The analysis allows for definition and characterization of variation aversion, liking, and neutrality. Copyright 1989 by The Econometric Society.
