A Specification Test for Choosing the “Right” Public-Good Price
统计比较了三种流行的公共品价格定义，推导并计算了错误定义下的参数估计偏差，发现一种定义明显较差，而另两种差异不大，并计算了公共品需求弹性及其方差以说明选择正确价格定义的重要性。
This article compares statistically three popular public-good price definitions. The bias of parameter estimates under the wrong definition is derived and calculated. One definition is found to be clearly inferior, whereas bias estimates indicate little difference between the two remaining definitions. Public-good demand elasticities and their variances are calculated to demonstrate the importance of choosing the “right” price definition.
