Regret theory predicts that choices over prospects will be systematically influenced by the juxtaposition of outcomes in the payoff matrix. Experiments have found apparent juxtaposition effects of this kind. However, these experiments have not controlled for "event-splitting effects" (ESEs), by...

A series of studies investigate the decision processes of actuaries, underwriters, and reinsurers in setting premiums for ambiguous and uncertain risks. Survey data on prices reveal that all three types of these insurance decision makers are risk averse and ambiguity averse. In addition, groups...

The use of contingent valuation (CV) methods for estimating the economic value of environmental improvements and damages has increased significantly. However, doubts exist regarding the validity of the usual willingness to pay CV methods. In this article, we examine the CV approach in light of...

Lengthy legal proceedings are often required before an individual who has unjustly lost income is compensated. The utility loss while waiting in straitened circumstances exceeds the utility gain from later compensation if compensation is merely monies lost plus interest. The excess loss will be...
