Microfoundations of Social Capital

We show that the standard trust question routinely used in social capital research is importantly related to cooperation behavior and we provide evidence on the microfoundation of this relation. We run a large-scale public goods experiment over the internet in Denmark using a design that enables us to disentangle preferences for cooperation from beliefs about others’ cooperation. We find that the standard trust question is a proxy for cooperation preferences rather than beliefs about others’ cooperation. Moreover, we show that the “fairness question”, a recently proposed alternative to the standard trust question, is also related to cooperation behavior but operates through beliefs rather than preferences.Social capital, Trust, Fairness, Public goods, Cooperation, Experiment
