演講摘要 : In this study, we synthesize the revealed preference theory underlying welfare analysis of public goods (e.g., environmental quality) through observing consumption of related commodities. An empirical strategy, consistent with the theory to uniquely derive use and nonuse values for a change in the public good, is proposed. We show that the weak complementarity assumption and the Willig condition, the common preference assumptions to support the revealed preference methods for non-market valuation, may be tested as parameter restrictions. An empirical study to illustrate the proposed strategy is presented. Results show that the weak complementarity assumption and the Willig condition generally do not hold in the case study, indicating that the consumer surplus derived from the indirect valuation method contains measurement errors.
