The role of beliefs, trust, and risk in contributions to a public good

This paper experimentally investigates the role of beliefs, trust, and risk in shaping cooperative behavior. By applying incentivized elicitation methods to measure these concepts, we find that beliefs about others’ behavior and trust are positively associated with cooperation in a public goods game. However, even though contributing unconditionally to a public good resembles a situation of making decisions under risk, elicited risk preferences do not seem to explain cooperation in a systematic way
