Measuring the Value of a Public Good: An Empirical Comparison of Elicitation Procedures
比较了假想诱导法和市场交易法在测量公共物品价值时的差异，发现假想情境中存在买卖价差，但重复市场交易后价值更符合边际效用递减规律，且市场能有效抑制损失厌恶行为。
The problems associated with accurately measuring the value of a public good in an applied setting are considered. The values obtained from hypothetical elicitation procedures are compared and contrasted with those obtained in a marketplace. When hypothetical measurements are elicited in the field, buying-selling discrepancies similar to those predicted by psychological models of behavior are observed. However, when the market-like elicitation process is repeated, values are more consistent with diminishing marginal utility. The authors cannot reject the hypothesis that these individuals exhibit loss- aversion behavior. The marketplace, however, is a strong disciplinarian of limiting this type of behavior.
