We use skin conductance responses and self-reports of hedonic valence to study the emotional basis of cooperation and punishment in a social dilemma. Emotional reaction to free-riding incites individuals to apply sanctions when they are available. The application of sanctions activates a...

The ratio bias - according to which individuals prefer to bet on probabilities expressed as a ratio of large numbers to normatively equivalent or superior probabilities expressed as a ratio of small numbers - has recently gained momentum, with researchers especially in health economics...

Assuming that people care not only about what others do but also on what others think, we study respect as a non-monetary source of motivation in a context where the length of the employment relationship is endogenous. In our three-stage gift-exchange experiment, the employer can express respect...

Experimental studies of social dilemmas have shown that while the existence of a sanctioning institution improves cooperation within groups, it also has a detrimental impact on group earnings in the short-run. Could the introduction of pre-play threats to punish have enough of a beneficial...

We study the attitudes of junior and senior employees towards strategic uncertainty and competition, by means of a market entry game inspired by Camerer and Lovallo (1999). Seniors exhibit higher entry rates compared to juniors, especially when earnings depend on relative performance. This...

We study how individuals adjust their judgment of fairness and unfairness when they are in the position of spectators before and after making real decisions, and how this adjustment depends on the actions they take in the game. We find that norms that appear universal instead take into account...

We conduct an artefactual field experiment using a diversified sample of passengers of public transportations to study attitudes towards dishonesty. We find that the diversity of behavior in terms of dis/honesty in laboratory tasks and in the field correlate. Moreover, individuals who have just...

This paper studies the influence of peers on the extensive margin of effort at work by means of a real-effort experiment in which subjects have to decide on the intensity of effort and when to stop working. Participants perform a task alone or in the presence of a peer. The feedback on the...

The 'ratchet effect' refers to a situation where a principal uses private information that is revealed by an agent's early actions to the agent's later disadvantage, in a context where binding multi-period contracts are not enforceable. In a simple, context-rich environment, we experimentally...

Agency theory assumes that tighter monitoring by the principal should motivate the agent to raise his effort level whereas the quot;crowding-outquot; literature suggests that it may reduce the overall work effort. These two assertions are not necessarily contradictory provided that the nature of...
