Individualized Geocoding in Stated Preference Questionnaires: Implications for Survey Design and Welfare Estimation
比较了陈述偏好调查中通用地图与个性化地图对偏好估计的影响，基于理论模型和缅因州河岸恢复案例，指出在特定情境下需提供个性化空间信息才能有效获取偏好。
This paper evaluates the common practice of generic mapping in stated preference valuation, in which identical policy area maps are shown to all respondents. This is compared to a more information-intensive alternative in which individualized maps identify the location of each respondent’s home relative to policy effects. The evaluation is grounded in a theoretical model clarifying the impact of individualized spatial information on preferences for non-market outcomes. The model is illustrated using an application of choice experiments to riparian restoration in coastal Maine. Results characterize valuation contexts for which valid preference elicitation likely requires the provision of individualized spatial information. <i></i>
