Trust and Expected Trustworthiness: Experimental Evidence From Zimbabwean Villages
通过津巴布韦24个紧密社区的实验，区分基于预期和非预期的信任行为，发现预期可信度解释了社区间一半以上的信任差异，但传统与重新安置社区的非预期动机不同。
An economic experiment involving 24 small, tightly knit communities allows us to distinguish between trusting or trust-like behaviour based on expectational and non-expectational motivations. A model linking trusting behaviour to expectations of trustworthiness explains over half of the variation across communities. However, the estimated parameters are different (while being similarly well defined) for traditional and resettled communities. This is taken as evidence that non-expectational motivations are at work and vary with community type. Both the data and certain stylised facts suggest that altruistic motivations matter less and motivations relating to a desire to 'community-build' matter more in resettled communities.
