Replication data for: Are There Environmental Benefits from Driving Electric Vehicles? The Importance of Local Factors

We combine a theoretical discrete-choice model of vehicle purchases, an econometric analysis of electricity emissions, and the AP2 air pollution model to estimate the geographic variation in the environmental benefits from driving electric vehicles. The second-best electric vehicle purchase subsidy ranges from $2,785 in California to -$4,964 in North Dakota, with a mean of -$1,095. Ninety percent of local environmental externalities from driving electric vehicles in one state are exported to others, implying they may be subsidized locally, even when the environmental benefits are negative overall. Geographically differentiated subsidies can reduce deadweight loss, but only modestly.

本研究结合车辆购置的理论离散选择模型（discrete-choice model）、电力排放的计量经济学分析以及AP2空气污染模型（AP2 air pollution model），对电动汽车行驶所带来的环境效益的地理差异进行估算。次优电动汽车购置补贴额度在加利福尼亚州为2785美元，在北达科他州则为-4964美元，整体均值为-1095美元。单个州内电动汽车行驶产生的本地环境外部性（environmental externalities）中，有90%会外溢至其他州，这意味着即便整体环境效益为负，当地仍可对电动汽车实施购置补贴。地理差异化补贴可降低无谓损失（deadweight loss），但效果有限。
