本研究は、EU ETSの市場安定化備蓄（MSR）政策が炭素価格水準とボラティリティに与えた影響を、合成対照法（SCM）を用いて評価した。韓国・ニュージーランド・中国をドナーとして反事実を構築し、2020年から2023年の4回のMSR実施がすべて平均価格を有意に引き上げたことを示した。また、MSR2（2021年）とMSR3（2022年）は価格ボラティリティを有意に低減し、市場安定化に部分的に成功した。プラセボテスト等の頑健性チェックも結果を支持している。
English
This study evaluates the impact of the EU ETS Market Stability Reserve (MSR) on carbon price levels and volatility using the Synthetic Control Method (SCM). Constructing a counterfactual with Korea, New Zealand, and China as donors, it finds that all four MSR implementations between 2020 and 2023 significantly raised average allowance prices. MSR2 (2021) and MSR3 (2022) also significantly reduced price volatility, indicating partial success in stabilizing market expectations. Robustness checks including placebo tests support the findings.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では2026年度のGXリーグ排出量取引の本格稼働が控えており、市場安定化メカニズムの設計は重要な論点。EUのMSRの実証結果は、日本の排出量取引制度における価格安定化策の参考になる。
In the global GX context
As the EU ETS is a global benchmark for carbon pricing, this causal evidence on the MSR's effectiveness informs policy design worldwide, including emerging carbon markets and the ongoing evolution of the EU ETS post-Phase 4.

📄 Abstract（原文）
This study examines the effects of the Market Stability Reserve (MSR) policy on carbon emission prices within the European Union Emissions Trading System (EU ETS), focusing on both price levels and volatility. Employing the Synthetic Control Method (SCM), the analysis constructs a counterfactual scenario using data from Korea, New Zealand, and China—countries that have not adopted the MSR. The validity of this donor pool is verified through cointegration tests and a Vector Error Correction Model, which confirm both long-run equilibrium relationships and short-run causal interactions with the EU ETS. The empirical analysis reveals that all four MSR implementations between 2020 and 2023 significantly increased the average price of EU allowances, thereby validating the policy’s effectiveness in addressing oversupply. Additionally, MSR2 (2021) and MSR3 (2022) are found to have significantly reduced price volatility, indicating the MSR’s partial success in stabilizing market expectations. Robustness checks, including placebo tests, support the credibility of the estimated effects. The findings affirm the MSR’s role as an effective market-based instrument for enhancing price stability, sustaining investment incentives in emissions reduction, and ensuring the long-term credibility of the EU ETS.
