Consistency of Risk Preference Measures: An Artefactual Field Experiment from Rural China
通过在中国农村开展人工实地实验，研究了激励性实验与非激励性调查两种风险偏好度量方法之间的一致性，发现模糊偏好可能是导致不一致的原因。
A variety of measures have been developed to elicit individual risk preferences. How these measures perform in the field, in particular in developing countries with non-student subjects, is still an open question. We implement an artefactual field experiment in rural China to investigate (i) consistency across incentivised experimental risk measures, (ii) consistency in risk preferences elicitation between non-incentivised survey measures and incentivised experiments, and (iii) possible explanations for risk preference inconsistency across measures. We find that inconsistent risk preferences across survey and experimental measures may be explained by ambiguity preferences. In the survey, subjects may mix risk and ambiguity preferences.
