Risk Aversion and Expected Utility of Consumption over Time
Abstract
The calibration theorem by Rabin (2000) implies that seemingly plausible smallstake choices under risk imply implausible large-stake risk aversion. This theorem is derived based on the expected utility of wealth model. However, Cox and Sadiraj (2006) show that such implications do not follow from the expected utility of income model. One may then wonder about the implications for more applied consumption analysis. The present paper therefore expresses utility as a function of consumption in a standard life cycle model, and illustrates the implications of this model with experimental small- and intermediate-stake risk data from Holt and Laury (2002). The results suggest implausible risk aversion parameters as well as unreasonable implications for long term risky choices. Thus, the conventional intertemporal consumption model under risk appears to be inconsistent with the data.Download Info
