摘要：The purpose of this paper is to describe the implications of the collective model of household behavior for the methods used to estimate the economic value of non-marketed environmental resources. The effects of public good and risk are considered, along with revealed and stated preference methods. To the extent the collective framework is adopted, then recover of individual preferences from household behavior requires distinguishing how preference and within household income allocations affect choices.
