Aggregate Deadweight Loss and Money Metric Social Welfare
提出一种无需对偏好做严格假设的计量方法，用于测量总无谓损失，并指出文献中常用的加总个体无谓损失来度量社会福利的方法无效，除非偏好或社会排序受到严格限制。
An econometric approach to the measurement of aggregate deadweight loss is proposed that does not require restrictive assumptions about preferences for validity. The measure can be interpreted as the loss in allocative efficiency and is independent of the distribution of individual welfare. An approach that is pervasive in the literature is to sum the individual measures of deadweight loss and interpret the resulting index as a measure of social welfare. The author shows that this approach is invalid unless individual preferences or the social ordering are severely restricted. An alternative method of evaluating money metric social welfare that does not require these restrictions is presented.
