As predicted by loss aversion, numerous studies find that penalties elicit greater effort than bonuses, even when the underlying payoffs are identical. However, loss aversion also predicts that workers will demand higher wages to accept penalty contracts. In six experiments I recruited workers...

We study the relative effectiveness of contracts that are framed either in terms of bonuses or penalties. In one set of treatments subjects know at the time of effort provision whether they have achieved the bonus / avoided the penalty. In another set of treatments subjects only learn the...

Empirically, labor contracts that financially penalize failure induce higher effort provision than economically identical contracts presented as paying a bonus for success, an effect attributed to loss aversion. This is puzzling, as penalties are infrequently used in practice. The most obvious...
