Beliefs are increasingly recognised as an important driver of behaviour, but measuring beliefs is not straightforward. We design a giving experiment to compare beliefs (about others) using different elicitation mechanisms when self-serving motives may compete with accuracy incentives. Consistent...

We propose a deterrence mechanism that utilizes insider information criminals collect through customary practices. Under this mechanism, a suspect caught committing a criminal act can nominate a person who has committed a similar crime, and only the more severe offender is penalized. Nash...
