This paper represents an intersection between two lines of research. The first is portfolio choice theory, which underlies much of finance; the second is the elicitation of preferences under uncertainty. The theory of the behaviour of financial markets builds heavily on portfolio choice theory;...

This paper reports on an experimental test of the Principle of Optimality in dynamic decision problems. This Principle, which states that the decision-maker should always choose the optimal decision at each stage of the decision problem, conditional on behaving optimally thereafter, underlies...

Much experimental effort has been expended in attempts to establish the relative superiority of Expected Utility theory and the many recently-developed alternatives as descriptions of the behaviour of subjects in risky choice decision problems. The cumulative evidence shows clearly that there is...

In many experiments, experimenters use the random lottery incentive mechanism and ask many questions to each subject. That is, at the end of the experiment, just one of the questions is picked at random, and the subject paid on the basis of their answer to this one question. The idea is that...

We carry out two experiments to test a model of herd behaviour based on the work of Banerjee (Quarterly Journal of Economics, CVII, 797–817, 1992). He shows that herding occurs as a result of people observing the actions of others and using this information in their own decision rule. In...

The recent spate of theoretical models of behaviour under ambiguity can be partitioned into two sets: those involving multiple priors and those not involving multiple priors. This paper provides an experimental investigation into the first set. Using an appropriate experimental interface we...

<Para ID="Par1">This paper identifies, and tests experimentally, a prediction of the Nash bargaining axioms that may appear counterintuitive. The context is a simple bargaining problem in which two players have to agree a choice from three alternatives. One alternative favours one player and a second favours...</para>

The random lottery incentive (RLI) mechanism (which involves subjects taking many decisions, only a randomly chosen one of which determines the payment to the subject) is widely used in many experiments, and hence its validity is of crucial importance to the inferences that can be drawn from the...
