A general approach to the evaluation of nonmarket goods

摘要

The paper considers the evaluation of a nonmarket good on the basis of a complete conditional demand system. It introduces two conditions allowing to identify a generally unique underlying preference ordering which can be employed for evaluation. The functional structure of the corresponding expenditure/indirect utility function and the demand system is described. The conditions proposed turn out to be equivalent to the property of base level independence in the equivalence scale literature. The approach is operational.
