日本語
本論文は、商業航空における是正課税の効果を分析。需要の異質性と不完全競争下で、低弾力性の消費者の価格感応度がビジネス消費者の7倍高いことを発見。デンマークでのジェット燃料税とノルウェー型のフライト固定税のシミュレーションでは、炭素の社会的費用のみを考慮した場合、税の外部性内部化効果は限定的であることを示す。
English
This paper analyzes corrective taxation in commercial aviation, finding that lower-elasticity consumers are 7 times more price-sensitive than business consumers. Simulations of jet fuel taxes and a fixed per-flight tax in Denmark show that taxes have limited efficacy in internalizing externalities when considering only the social cost of carbon.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも航空業界への炭素税導入が議論されているが、本論文は需要の異質性を考慮した税設計の重要性を示しており参考になる。
In the global GX context
This paper provides a rigorous simulation of aviation carbon taxes in Denmark and Norway, highlighting the limited efficacy when only considering the social cost of carbon, relevant for global aviation carbon pricing discussions.
👥 読者別の含意
🔬研究者:Provides empirical evidence on price elasticity differences and tax simulation results for aviation carbon pricing.
🏢実務担当者:Airlines can use findings to anticipate regulatory changes and understand potential cost impacts.
🏛政策担当者:Tax design should account for demand heterogeneity and imperfect competition; limited efficacy suggests complementary policies may be needed.
📄 Abstract(原文)
Corrective taxation has the potential to reduce the negative environmental impacts of aviation, particularly carbon emissions, as well as air pollution. However, in a setting with demand heterogeneity and imperfect competition, optimally setting a tax is not trivial. I find that lower-elasticity consumers are 7 times more price-sensitive than business consumers. I simulate two alternative taxation schemes in Denmark (jet fuel taxes, and a fixed per-flight tax, as in Norway) and find that taxes have limited efficacy in internalizing externalities when considering only the social cost of carbon.
