Cooperative Membership as a Trust and Trustworthiness Reinforcing Device: Results from a Field Experiment in the Philippines
通过菲律宾蔗农的信任博弈实验，发现合作社成员身份能提升信任和可信赖性，且这种效应存在内群体偏好，仅对成员间有效。
Abstract We test the hypothesis that cooperative membership is a trust and trustworthiness reinforcing device and that, as such, it affects (in a trust game) both trustors' and trustees' transfers and beliefs. In considering trust games played by sugar farmers in the Philippines, we find that (i) cooperative membership induces higher levels of trust and trustworthiness even in non-members because the players' behaviour is influenced by the information about their counterparts' cooperative membership status; (ii) an in-group bias is at work since, contrary to non-members' expectations, the positive affiliation-trustworthiness link works only among cooperative members.
