美国和许多其他国家正在大幅收紧乘用车的燃油经济性标准。更高的燃油经济性降低了每英里的驾驶成本，并可能增加行驶里程，称为反弹效应。行驶里程对燃油经济性的弹性大小是燃油经济性标准福利分析中的一个重要参数，但所有以前的微观数据估计都至少采用了以下三种行为假设之一：（a）燃油经济性与车辆和家庭属性无关;（B）对于多车辆家庭，每辆车在统计分析中可以被视为一个独立的观察结果;以及（c）汽油价格对车辆行驶里程的影响与燃料经济性的影响成反比。放松这些假设的两种方法产生了对反弹效应的较大估计;燃油经济性增加1%会使驾驶增加0.2%或0.4%，具体取决于方法，但估计值在统计上彼此没有显著差异。
The United States and many other countries are dramatically tightening fuel economy standards for passenger vehicles. Higher fuel economy reduces per-mile driving costs and may increase miles traveled, known as the rebound effect. The magnitude of the elasticity of miles traveled to fuel economy is an important parameter in welfare analysis of fuel economy standards, but all previous estimates from micro data impose at least one of three behavioral assumptions: (a) fuel economy is uncorrelated with vehicle and household attributes; (b) for multivehicle households, each vehicle can be treated as an independent observation in statistical analysis; and (c) the effect of gasoline prices on vehicle miles traveled is inversely proportional to the effect of fuel economy. Two approaches to relaxing these assumptions yield a large estimate of the rebound effect; a one percent fuel economy increase raises driving 0.2 or 0.4 percent, depending on the approach, but the estimates are not statistically significantly different from one another.
