Abstract This paper exploits differences in fuel efficiency between hybrid vehicles and their gasoline counterparts to investigate two key questions relating to fuel economy standards: whether consumers properly value fuel economy (the energy paradox) and whether improved fuel efficiency increases travel (the rebound effect). Several vehicles, such as the Honda Civic, are available in both hybrid and gasoline versions. Such vehicles share many of the same attributes, with the main difference being fuel efficiency, and provide a unique setting to examine these issues. We emphasize methodological and data issues that typically have not been a focus in prior studies, such as partial observability, endogeneity, and measurement error. Estimates of the rebound effect and consumer valuation of fuel economy remain imprecise despite the use of the detailed household level data and sound methodology to handle limitations with these data. The inability to precisely estimate these important policy questions suggests it is useful to obtain reliable, detailed data on household vehicles, paired with rich household- and person-level survey data.

车辆的选择和利用：通过部分观察到的选择和混合动力对提高估计

摘要本文利用混合动力汽车与汽油同行的燃油效率差异来研究与燃油经济性标准相关的两个关键问题：消费者是否正确地重视燃油经济性（能源悖论）以及提高的燃油效率是否会增加行驶效率（回弹效应）。混合动力和汽油版本均提供了多种车辆，例如本田思域。这样的车辆具有许多相同的属性，主要区别在于燃油效率，并提供了独特的环境来研究这些问题。我们强调以前的研究中通常没有关注的方法和数据问题，例如部分可观察性，内生性和测量误差。尽管使用了详细的家庭水平数据和合理的方法来处理这些数据的局限性，但对反弹效应和消费者对燃油经济性的估计仍不准确。无法精确估计这些重要的政策问题表明，获得可靠，详细的家用车辆数据以及丰富的家庭和个人层面的调查数据非常有用。
