美国联邦政府于2011年9月首次颁布了中型和重型卡车的燃油效率标准。使用这一政策工具的成本通常取决于市场中存在的摩擦或消费者的短视，使得车辆购买者低估了提高燃料效率所带来的未来燃料节省。我们通过使用经典享乐方法的最新进展来估计燃油效率支付意愿的分布，来衡量长途卡车车主低估未来燃油节省的程度。我们发现，卡车车主为燃油效率支付的意愿存在显着的异质性，燃油效率对价格的弹性范围从第10百分位数的0.51到第90百分位数的1.33，平均值为0.91。将这些结果与提高燃油效率所带来的未来燃油节省估计相结合，我们发现长途卡车车主愿意为燃油效率提高1%而支付的费用平均仅为预期未来燃油节省的29.5%。这些结果表明，引入重型卡车的燃油效率标准可能是一个有效的政策工具，以提高中重型卡车的燃油经济性。
The U.S. federal government enacted fuel efficiency standards for medium and heavy trucks for the first time in September 2011. Rationales for using this policy tool typically depend upon frictions existing in the marketplace or consumers being myopic, such that vehicle purchasers undervalue the future fuel savings from increased fuel efficiency. We measure by how much long-haul truck owners undervalue future fuel savings by employing recent advances to the classic hedonic approach to estimate the distribution of willingness-to-pay for fuel efficiency. We find significant heterogeneity in truck owners’ willingness-to-pay for fuel efficiency, with the elasticity of fuel efficiency to price ranging from 0.51 at the 10th percentile to 1.33 at the 90th percentile, and an average of 0.91. Combining these results with estimates of future fuel savings from increases in fuel efficiency, we find that long-haul truck owners’ willingness-to-pay for a 1 percent increase in fuel efficiency is, on average, just 29.5 percent of the expected future fuel savings. These results suggest that introducing fuel efficiency standards for heavy trucks might be an effective policy tool to raise medium and heavy trucks’ fuel economy.
