摘要

虽然许多研究发现，消费者在购买新车时总是低估燃料成本，但这种信息缺失能否通过干预来纠正尚不清楚。本文结合了在爱尔兰共和国进行的两项全国性实验的结果——一项是在线离散选择实验，另一项是展厅随机对照试验，后者测试了能源成本和二氧化碳信息对汽车选择的影响。在线实验的结果表明，提供货币能源成本信息，特别是在更长的时间范围内，会增加选择纯电动汽车（BEV）的可能性。然而，实地试验结果并未显示在车辆销售点提供信息的效果。这突出了影响现实世界购买的困难，以及信息提供的来源和时间的重要性。

Communicating car costs: Results from stated and revealed preference experiments

While many studies find that consumers consistently undervalue fuel costs when making a new car purchase, whether this information failure can be corrected through an intervention remains unclear. This paper combines the results of two nationwide experiments conducted in the Republic of Ireland − an online discrete choice experiment and a showroom randomized controlled trial which test the provision of energy cost and CO₂ information on car choices. Findings from the online experiment suggest that providing monetary energy cost information, particularly when it is framed over longer time horizons increases the probabilty of selecting a battery electric vehicle (BEV). Field trial findings however do not show an effect of information provision at the point of vehicle sale. This highlights the difficutly in influencing real-world purchases, and the importance of source and timing in information provision.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
