Evidence on Individual Preferences for Longevity Risk The standard model of intertemporal choice assumes risk neutrality toward the length of life: due to additivity, agents are not sensitive to a mean preserving spread in the length of life. Using a survey fielded in the RAND American Life Panel (ALP), this paper provides empirical evidence on possible deviation from risk neutrality with respe...

As regards decreasing cotton cultivation in Iran during these years, the degree of risk taken by a cotton cultivator in the agricultural part is important. The studies showed that the cotton crop yield during the past years did not have enough growth and the cotton cost product in the period of study cotton production costs, has increased. In this paper, the risk orientation of cotton cultivato...

Accident Risk, Gender, Family Status and Occupational Choice in the UK Many studies show that women are more risk averse than men. In this paper, following DeLeire and Levy (2004) for the US, we use family structure as a proxy for the degree of risk aversion to test the proposition that those with strong aversion to risk will make occupational choices biased towards safer jobs. In line with DeL...

We investigate how people allocate a limited set of resources between multiple risky prospects. We found that only a small percentage of decisions followed some form of naive diversification or mean-variance optimization. In general, people were less mean-variance optimal than a naive 1/N heuristic. Aspects of choice sets, such as domain, skew, and second order stochastic dominance, affected re...

Tax-Benefit Systems in Europe and the US: Between Equity and Efficiency Whether observed differences in redistributive policies across countries are the result of differences in social preferences or efficiency constraints is an important question that paves the debate about the optimality of welfare regimes. To shed new light on this question, we estimate labor supply elasticities on microdata...

We consider a multi-product newsvendor using an exponential utility function. We first establish a few basic properties for the newsvendor regarding the convexity of the model and monotonicity of the impact of risk aversion on the solution. When the product demands are independent and the ratio of the degree of risk aversion to the number of products is sufficiently small, we obtain closed-form...

Stackelberg security games (SSGs) are now established as a powerful tool in security domains. In this paper, we consider a new dimension of security games: the risk preferences of the attacker. Previous work assumes a risk-neutral attacker that maximizes his expected reward. However, extensive studies show that the attackers in some domains are in fact risk-averse, e.g., terrorist groups in cou...

Can Risk Aversion Explain Schooling Attainments? Evidence from Italy Using unique Italian panel data, in which individual differences in behavior toward risk are measured from answers to a lottery question, we investigate if (and to what extent) risk aversion can explain differences in schooling attainments. We formulate the schooling decision process as a reduced-form dynamic discrete choice. ...

At rst glance, there would appear to be no relationship between Bell's (1988) concept of one-switch utility functions and that of a stronger measure of risk aversion due to Ross (1981). We show however that speci c assumptions about the behavior of the stronger measure of risk aversion also give rise to the linex utility function which belongs to the class of one-switch utility functions. In pa...
