This paper experimentally investigates whether risk-averse individuals punish less if the outcome of punishment is uncertain than when it is certain. Our design includes three treatments: Baseline in which the one-shot prisoner’s dilemma game is played; Certain Punishment in which the...

We conduct a prisoner’s dilemma experiment with a punishment/reward stage, where punishments and rewards are risky. This is compared with a risk free treatment. We find that subjects do not change their behavior in the face of risky outcomes. Additionally, we measure risk attitude and the...

Does a mere availability of punishment increase cooperation in a one-shot prisoner’s dilemma game? In our experiment we observe that the subjects almost never use punishment. Consistently, the data shows no increase in the cooperation rate as the subjects correctly anticipated that they would...

Subjects are asked to report their confidence in their own decisions regarding the Ellsberg three color urn. Subjective confidence is measured via a 5 point Likert scale. Surprisingly, subjects are more confident in their answer for the more complicated two color question, compared to the simple...
