Do people only reject interference and keep control to affect the outcome? We find that 20% of subjects reject unrequired help and insist on their solution to a problem—although doing so is costly and does not change the result. We tease out the motives by varying the information available to...

Incentives often fail in inducing economic agents to engage in a desirableactivity; implementability is restricted. What restricts implementability?When does re-organization help to overcome this restriction?This paper shows that any restriction of implementabilityis caused by an identification...

Individuals exhibit a randomization preference if they prefer random mix-tures of two bets to each of the involved bets. Such preferences provide thefoundation of various models of uncertainty aversion. However, it has to ourknowledge not been empirically investigated whether uncertainty-averse...

We investigate a team setting in which workers have different degrees of commitment to theoutcome of their work. We show that if there are complementarities in production and if theteam manager has some information about team members, interventions that the managerundertakes in order to assure...

Bubbles in asset markets have been documented in numerous experimentalstudies. However, all experiments in which bubbles occurpay dividends after each trading day. In this paper we study whetherbubbles can occur in markets without dividends. We investigate therole of two features that are...

When designing incentives for a manager, the trade-off between insuranceand a “good” allocation of effort across various tasks is oftenidentified with a trade-off between the responsiveness (sensitivity, precision,signal-noise ratio) of the performance measure and its similarity(congruity,...

How does the environment of an organization influence whether workers voluntarily provide effort? We study the power relationship between a non-profit unit (e.g. university department, NGO, health trust), where workers care about the result of their work, and a bureaucrat, who supplies some...
