Tournaments are widely used to assign bonuses and determine promotions because of the link between relative performance and rewards. However, performing relatively well (poorly) may also yield psychological benefits (pain). This may also stimulate effort. Through a real-effort artefactual field...

An investor's choice between safe and risky assets has long been seen as a behavior toward risk: more risk-averse investors buy more of the safe asset. Applying this intuition to incentive pay contracts, we develop a model and an experiment that show, in a very general setting, that the choice...
