According to several psychological and economic studies, non-binding communication can be an effective tool to increase trust and enhance cooperation. This paper focuses on reasons why people stick to a given promise and analyzes to what extent image concerns of being perceived as a promise...

Actual behaviour is influenced in important ways by moral emotions, for instance guilt or shame (see among others Tangney et al., 2007). Belief-dependant models of social preferences using the framework of psychological games aim to consider such emotions to explain other-regarding behaviour....

The model of time-inconsistent procrastination by O'Donoughe and Rabin shows that individuals who are not aware of their present-bias (naïve) procrastinate more than individuals who are aware of it (sophisticated) or are not present-biased (time-consistent). This paper tests this prediction. We...

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...

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...

We conducted a lab experiment to examine (1) whether luck-based income influences honesty in a subsequent, unrelated decision, (2) whether the perceived agency over an uncertain event affects the interplay between luck and honesty, and (3) whether accumulated previous luck-based incomes...

We introduce a modification to the two-timescale games studied in the evolution of preferences (EOP) literature. In this modification, the strategic process occurring on the long timescale is learning by an individual across his or her lifetime, not natural selection operating on genomes over...
