What do happiness and health satisfaction data tell us about relative risk aversion?
In this paper we provide estimates of the coefficient of relative risk aversion using information on self-reports of subjective personal well-being from the 2006 Gallup World Poll. We expand the existing literature on the use of happiness data to analyze economic issues by considering the implications of allowing for health state dependence in the utility function. Our estimates of relative risk aversion using pooled data from various country groupings are smaller than one, suggesting less concavity than log utility. We also find that controlling for health dependence generally reduces these ...
Stability of risk preference
Stability of preferences is central to how economists study behavior. This paper uses panel data on hypothetical gambles over lifetime income in the Health and Retirement Study to quantify changes in risk tolerance over time and differences across individuals. The maximum-likelihood estimation of a correlated random effects model utilizes information from 12,000 respondents in the 1992-2002 HRS. The results support constant relative risk aversion and career selection on preferences. While risk tolerance changes with age and macroeconomic conditions, persistent differences across individuals ...
