People typically exhibit greater sensitivity to losses than to equivalent gains when making decisions. We investigated neural correlates of loss aversion while individuals decided whether to accept or reject gambles that offered a 50/50 chance of gaining or losing money. A broad set of areas (including midbrain dopaminergic regions and their targets) showed increasing activity as potential gain...

This study investigates loss aversion when the reference point is state-dependent. Using a state-dependent structure, prospects are more attractive if they depend positively on the reference point and are less attractive in case of negative dependence. In addition, the structure is neutral in the sense that it avoids an inherent aversion to risky prospects and yields no loss when the prospect a...

Introduction Obsessive-compulsive disorder (OCD) patients show abnormalities in decision-making and, clinically, appear to show heightened sensitivity to potential negative outcomes. Despite the importance of these cognitive processes in OCD, few studies have examined the disorder within an economic decision-making framework. Here, we investigated loss aversion, a key construct in the prospect ...

Decision making under risk entails the anticipation of prospective outcomes, typically leading to the greater sensitivity to losses than gains known as loss aversion. Previous studies on the neural bases of choice-outcome anticipation and loss aversion provided inconsistent results, showing either bidirectional mesolimbic responses of activation for gains and deactivation for losses, or a speci...

Smart time of use tariffs are a key part of most government’s strategies to ensure our future electricity supply is clean, affordable and secure – but will consumers be willing to switch to them? This paper presents the results of a survey experiment conducted on a nationally representative sample of 2020 British energy bill payers. The data suggests that over a third of bill payers are in favo...

This article presents the results of a survey designed to test, with economically sophisticated participants, Ellsberg’s ambiguity aversion hypothesis, and Smithson’s conflict aversion hypothesis. Based on an original sample of 78 professional actuaries (all members of the French Institute of Actuaries), this article provides empirical evidence that ambiguity (i.e. uncertainty about the probabi...

This paper characterizes the conditions for risk aversion in cumulative prospect theory where risk aversion is defined in the strong sense of Rothschild and Stiglitz (1970). Under weaker assumptions than differentiability we show that risk aversion implies convex weighting functions for gains and for losses but not necessarily a concave utility function. Also, we investigate the exact relations...

Adapting behavior to changes in the environment is a crucial ability for survival but such adaptation varies widely across individuals. Here, we asked how humans alter their economic decision-making in response to emotional cues, and whether this is related to trait anxiety. Developing an emotional decision-making task for functional magnetic resonance imaging, in which gambling decisions were ...
