We test experimentally an explanation of over and under confidence as motivated by (perhaps unconscious) strategic concerns, and find compelling evidence supporting this hypothesis in the behavior of participants who send and respond to others ́statements of confidence about how well they have...

Cooperation problems are at the heart of many everyday situations. In this paper, we propose a very simple and light-handed mechanism to sustain cooperation and test its performance in a rich laboratory environment. The mechanism moderates cooperation by controlling experiences, more...

We examine whether the "Level-k" model of strategic behavior generates reliable cross-game predictions within an individual. We find no correlation in subjects' estimated levels of reasoning across two families of games. Furthermore, estimating a higher level for Ann than Bob in one family of...

We study experimentally how (un)selfish lies are reciprocated – or not – in subsequent economic interactions in the labor market. We find that while selfish lies are punished (negative reciprocity), prosocial and altruistic lies are neither punished nor rewarded (lack of positive...

Privacy law relies on the argument that consent does not entail any relevant impediments for the liberty of the consenting individual. Challenging this argument, we experimentally investigate whether consent to the publication of personal information in cyberspace entails self-coercion on a...

Experimental social scientists working at research-intensive institutions deal inevitably with subjects who have most likely participated in previous experiments. It is an important methodological question to know whether participants that have acquired a high level of lab-sophistication show...
