We study risk aversion and prudence in medical treatment decisions. In a laboratory experiment, we investigate the frequency and intensity of second- and third-order risk preferences, as well as the effect of the medical decision context. Risk preferences are assessed through treatment...

We report results from experimental first-price, sealed-bid, all-pay auctions for a good with a common and known value. We observe bidding strategies in groups of two and three bidders and under two extreme information conditions. As predicted by the Nash equilibrium, subjects use mixed...

This paper extends choice theory by allowing for the interaction between cognitive costs and imitative dynamics. The authors experimentally investigate the role of imitation when participants face a task which is costly in cognitive terms. In order to disentangle different choice dynamics, they...

We propose a task for eliciting attitudes towards risk that is close to real world risky decisions which typically involve gains and losses. The task consists of accepting or rejecting gambles that provide a gain with probability p and a loss with probability 1 − p. We employ finite mixture...

In this paper we assess the importance of sample type in the estimation of risk preferences. We elicit and compare risk preferences from student subjects and subjects drawn from the general population, using the multiple price list method devised by Holt and Laury in their paper Risk Aversion...

Solving the exploration/exploitation trade-off is a fundamental issue for an organism living in an uncertain and changing environment. This review describes how a stream of cognitive neuroscience studies linked exploratory behaviour to structures in the human prefrontal cortex, then identified...

In this paper we assess the importance of sample type in the estimation of risk preferences. We elicit and compare risk preferences from student subjects and subjects drawn from the general population, using the multiple price list method devised by Holt and Laury in their paper Risk Aversion...

We provide an experimental test of the traveler's dilemma using individual and group data. Our investigation aims to assess whether individual decisions differ significantly from group decisions. Experimental findings reported in this paper show that: (1) groups are always more rational – i.e....

We present a theory of discrete choice with information costs that supports deliberate stochastic choice. We use a unique experimental dataset to distinguish between errors arising from limitations on a decision maker's cognitive abilities and conscious disregard of information. Experimental...

Using online price comparison and shopping platforms makes experiencing slow connections, lags and waiting times for information an unfortunate reality. However, little attention has been paid to analyzing the effects of such delayed display of information on product choice behavior. This...
