Contingent Valuation and Social Choice
检验了条件估值法在估计自然资源存在价值时的心理物理稳健性、统计可靠性和经济合理性，并开发了扩展的支付意愿模型和计量技术，通过美国西部荒野保护实验质疑了该方法的可靠性。
Abstract The contingent valuation method for estimating the existence value of natural resources is examined for psychophysical robustness, statistical reliability, and economic sensibility. Extensions of standard models for willingness‐to‐pay, and suitable econometric techniques for analyzing these models, are developed. The analysis is applied to a series of experiments on the value of preserving wilderness areas in the western United States. The results call into question the reliability of the CV method for estimating existence values.
