英文文献：Willingness to Pay for Emission Reductions with E85-愿意用E85来支付减排费用

英文文献摘要：
This study examines consumers' WTP for reductions in greenhouse gas emissions from E85 as opposed to gasoline. Data were collected via a contingent choice exercise in a 2009 national online survey. As part of the fuel choice exercise, several fuel attributes were allowed to vary including emission reductions, import level, proximity of fuel availability, price, and fuel blend (E85 or regular gasoline). A random parameters model with demographics and attitudes interacted with emission reductions was estimated. The resulting estimates suggest that, overall the WTP for an emission reduction is not statistically significant. However, for some demographic and attitudinal profiles, the WTP is significant. An example profile includes younger age, female, concerned about climate change, not supportive of additional drilling, supportive of farmland being used for fuel, own or are likely to own a FlexFuel vehicle, and primary vehicle not an SUV.
这项研究调查了消费者对E85与汽油相比所减少的温室气体排放的期望。数据是通过2009年全国在线调查的或有选择练习收集的。作为燃料选择的一部分，几个燃料属性被允许变化，包括排放减少、进口水平、燃料的接近程度、价格和燃料混合(E85或普通汽油)。估计了一个人口统计和态度与减排相互作用的随机参数模型。由此得出的估计结果表明，总体而言，减少排放的目标在统计上并不显著。然而，就某些人口和态度方面的情况而言，世界发展目标是重要的。例如，年龄较低、女性、关心气候变化、不支持额外钻探、支持将农田用作燃料、拥有或可能拥有一辆FlexFuel汽车，以及非SUV的主要车辆。
