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...

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

Food labels are supposed to quickly inform consumers about the nutritional values of products. We provide evidence that in a system where labels are voluntary, they are systematically distorted. The probability of finding a label on a product of the category with the highest nutritional value is...

As illustrated by the famous Ellsberg paradox, many subjects prefer to bet on events with known rather than with unknown probabilities, i.e., they are ambiguity averse. In an experiment, we examine subjects’ choices when there is an additional source of ambiguity, namely, when they do not know...

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this 'crowding out' phenomenon, using standard economic arguments. The...

Do people only reject interference and keep control in order 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...

Previous experiments observe a chain of unkindness: unkindly treated people treat an innocent third party unkindly. As a remedy, it has been proposed that the unkindly treated person engages in emotional regulation by writing a letter to the unkind person. Indeed, subjects who received little...

When groups face difficult problems, the voice of experts may be lost in the noise of others' contributions. We present results from a "naturally noisy" setting, a large first-year undergraduate class, in which the expert's voice is "lost" to such a degree that it is in fact optimal for all...
