We present a theoretical model of a linear public good game in which heterogeneous players express social approval after observing contributions. The model explains how social approval is expressed and predicts positive contributions if subjects have a preference for social approval. Using a controlled laboratory experiment we test our model. In the experiment, subjects conduct computerized tas...

Devising a new experimental procedure to measure such conformity in a judgment task, we compare the degree of conformity in groups with varying gender composition. Overall, our experiments offer little evidence that gender composition affects expression of minority...

We investigate the complexity of temporal defeasible logic, and propose an efficient algorithm to compute the extension of any theory. The logic and algorithm are discussed in regard to modeling deadlines and normative retroactivity.

Résumé : La terminologie connaît depuis plusieurs années un tournant linguistique important. On s’intéresse aujourd’hui davantage aux mots et à leur utilisation en discours qu’à connaître les choses qu’ils peuvent dénoter.
