An uncertain and not just risky situation may be modeled using so-called belief functions assigning lower probabilities to subsets of outcomes. In this article we extend the von Neumann-Morgenstern expected utility theory from probability measures to belief functions. We use this theory to...

This article reports on a laboratory study of moral hazard in insurance markets. The experimental literature or the provision of public goods suggests that agents often sacrifice their narrowly defined self-interest for the good of the group. However, in those experiments, losses are...

Regulations to promote health and safety that are exceptionally costly relative to the expected health benefits may actually worsen health and safety, since compliance reduces other spending, including private spending on health and safety. Past studies relating income and mortality give...

In surveys of 3,000 households, we have found that people attach less importance to saving lives in the future than to saving lives today, and less importance to saving older persons than to saving younger persons. For the median respondent, saving six people in 25 years is equivalent to saving...

This article is concerned with criteria of choice under uncertainty which are based on long sequences of independent experiments. To state a rule of comparison for such sequences, we first specify it for sequences of certain numbers (say, of certain incomes). Eventually, the problem is reduced...

Constraints on the use of benefit-cost tests have generated increased interest in risk-risk analysis as a regulatory test. The effect on individual mortality of the income losses arising from regulatory expenditures can be determined from direct empirical estimates, which this article surveys....

In this article we study behaviorally consistent stopping rules in an unbounded search from a known distribution with no recall and with positive search cost. We show that if the searcher's preferences are quasi-convex in the probabilities, then behaviorally consistent search strategies in the...
