Individual and Household Willingness to Pay for Public Goods
探讨公共物品的支付意愿应以个人还是家庭为单位来测量，发现家庭成员的利他行为会导致家庭支付意愿低于个人支付意愿之和，并讨论了测量选择与实施问题。
Abstract The issue of whether willingness to pay (WTP) for the benefits generated by a public good should be elicited on an individual or on a household basis is addressed. Differences between individual and household WTP may arise when members of the household are mutually altruistic. It is shown that, for general specifications of altruism, household WTP is less than the sum of household members' individual WTP. Implications for the choice between household and individual measures of WTP are considered, and issues in the elicitation of household WTP are addressed.
