The Extent of Information: Its Relevance for Random Utility Models
研究了研究者对休闲者选择集的不同定义如何影响随机效用模型的参数和福利估计，发现选择集定义对估计结果敏感，且不同熟悉度的场所关闭的福利度量差异显著。
This paper examines the effect of the researcher's definition of a recreator's choice set on the parameter and welfare estimates from standard random utility models. Three choice set definitions are compared: choice sets based on all alternatives within the survey, those alternatives within a specified distance from the respondents home, and alternatives familiar to the individual. We show that parameter and welfare estimates are sensitive to the definition of the choice set. Welfare measures of site closures differ in varying ways depending on the familiarity level of the sites in question.
