Abstract

Although not without criticism, carbon pricing has been identified as a key instrument to support the energy transition process, as it can convey the signal of the actual cost of carbon in relative prices. However, when price and tax elasticities are considered separately, the international literature has shown that energy demand may be more sensitive to changes in tax rates. We estimate gasoline and diesel demand elasticities for Italian households using a dynamic model on a custom-built pseudo-panel. Our results confirm that household demand for transport fuels is more sensitive to the tax component than to the oil price, controlling for income level, age and cohort effects. These results have important implications for the potential effectiveness of transport fuel taxation in setting the decarbonisation pathway: a lower tax rate is required to achieve the target than that assumed on the basis of gross price elasticities.

交通脱碳:我们能依靠燃油税吗?
碳定价被认为是支持能源转型进程的一个关键手段,因为它能以相对价格传递碳的实际成本信号。然而,如果将价格和税收弹性分开考虑,国际文献表明,能源需求可能对税率的变化更为敏感。我们在定制的伪面板上使用动态模型估算了意大利家庭的汽油和柴油需求弹性。我们的结果证实,在控制收入水平、年龄和队列效应的情况下,家庭对运输燃料的需求对税收部分比对油价更敏感。这些结果对交通燃料税在制定去碳化路径方面的潜在有效性具有重要影响:要实现目标,所需的税率要低于根据总价格弹性假设的税率。

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.
