Testing Efficient Risk Sharing with Heterogeneous Risk Preferences: Comment
指出Mazzocco和Saini（2012）提出的允许偏好异质性的有效风险分担检验存在结果误报，纠正后的结果并不支持考虑异质性偏好的重要性。
Mazzocco and Saini (2012) propose and implement a test of efficient risk sharing that allows for preference heterogeneity. They motivate their approach as yielding different results from those of a standard efficiency test with homogeneous preferences. We show that the standard efficiency test results are misreported in their paper and that the correctly reported results do not present as compelling a case for the importance of accounting for heterogeneous preferences.
