Shafer's evidence theory is a branch of the mathematics of uncertain reasoning that allows for novel possibilities to be conceived by a decision-maker. Many of its findings exhibit striking similarities with an alternative decision theory purported by Shackle in the 1950s, before expected...

This paper presents experimental evidence about how individuals learn from information that comes from inside versus outside their ethnic group. In the experiment, Thai subjects observed information that came from Americans and other Thais that they could use to help them answer a series of...

While many learning models have been proposed in the game theoretic literature to track individuals’ behavior, surprisingly little research has focused on how well these models describe human adaptation in changing dynamic environments. Analysis of human behavior demonstrates that people are...

Earlier experiments have shown that under little information subjects are hardly able to coordinate even though there are no conflicting interests and subjects are organised in fixed pairs. This is so, even though a simple adjustment process would lead the subjects into the efficient, fair and...

We study search behavior in a generalized "secretary problem" environment in which consumers search sequentially for the best alternative from a known and finite set of multi-attribute alternatives. In contrast to most previous studies, we make no distributional assumptions about the quality of...

The growing literature on learning in games has produced various results on the predictive success of learning theories. These results, however, were based on various methods of comparison. The present paper uses experimental data on a set of four games in order to check on the robustness of...

This study describe an experiment on individual learning in the domain of cognitive economics. The authors’ main goal is to observe and to describe how subjects elaborate rules and regularities in problem solving. Involved subjects are asked to choose between different scores related to an...

Investors systematically deviate from rationality when making financial decisions, yet the mechanisms responsible for these deviations have not been identified. Using event-related fMRI, we examined whether anticipatory neural activity would predict optimal and suboptimal choices in a financial...

We study the effects of unequal representation in the interest-group system on the degree of information transmission between a lobbyist and a policymaker. Employing a dynamic cheap-talk model in which the lobbyist cares instrumentally about his reputation for truthtelling, we show that the...
