Heterogeneous Preferences Regarding Global Climate Change
使用随机参数Logit模型分析人们对缓解全球气候变化的支付意愿，发现偏好存在显著异质性，支付意愿随影响范围增加而上升，且对两个不同时间跨度的偏好相同。
We examine the structure of preferences for mitigating impacts of global climate change that will not occur during the lifetimes of most who are alive today. Because no market data exist for such distant markets, a statedpreference approach is used. The analysis is based on the random-parameters logit model, and the results indicate substantial heterogeneity in respondent preferences, that mean willingness to pay is a significant and increasing function of the scope of the impact, and, provocatively, that respondents have the same preferences over the two very different time horizons that we consider. © 2000 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
