The common ratio effect is a well-attested violation of expected utility theory. This paper uses four principles of dynamic choice to characterize alternative theoretical strategies for explaining the effect. It reports an experiment which tests these principles and, by implication, several...

The paper presents a model in which a population of agents repeatedly play games against nature; the rules of behavior followed are revised over time through a process of imitation. For binary decisions, imitation selects rules consistent with a preference relation of the kind proposed by SSB...

This paper defines the concept of a justifiable strategy, that of a justification theory (which shows strategies to be justifiable) and that of a complete justification theory (which for every strategy shows whether it is justifiable or not). An impossibility result is proved, showing that there...

This paper presents an experiment that is designed to be more effective than previous studies at reproducing in the laboratory the affective experiences of risk-taking, such as hope, fear, thrill, pain of loss, regret, disappointment or elation. The use of dynamic choice problems involving...
