旧社会主義25カ国での2010年・2023年調査を用い、制度への信頼と家計支出が気候対策への支払意思（所得の拠出や増税の受容）にどう関係するかを分析。両者とも正の関連を示すが、2010→2023年で所得効果は弱まり信頼効果が強まった。気候懸念だけでは負担を伴う政策への支持は保証されず、制度の信頼性・透明性が資金調達の政治的可否を左右すると論じる。
English
Using 2010 and 2023 Life in Transition Survey waves across 25 post-socialist countries, the study examines how institutional trust and household expenditure relate to willingness to pay for climate action via income contributions or higher taxes. Both are positively associated with WTP, but between 2010 and 2023 the income effect weakened while the trust effect strengthened, especially in post-Soviet, Baltic and Balkan groups. Climate concern alone does not ensure support for costly mitigation; institutional credibility and confidence in transparent, fair use of funds shape political feasibility.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では炭素税・GX経済移行債など国民負担を伴う政策の受容性が論点となる。制度への信頼が支払意思を左右するという知見は、GX政策の広報・説明責任やトランジション・ファイナンスへの信頼醸成を考える上で示唆的。
In the global GX context
As carbon pricing and transition finance scale under ISSB/CSRD-era disclosure, this paper links public trust in institutions to the political feasibility of financing mitigation—relevant to how governments and disclosure regimes build credibility for costly climate policy.
👥 読者別の含意
🔬研究者:制度信頼と所得が気候政策の支払意思に与える影響の時系列的変化を、地域別に実証した参照点となる。
🏢実務担当者:炭素価格や移行コストの社会受容性が制度信頼に依存する点を、政策リスク評価に組み込む材料になる。
🏛政策担当者:負担を伴う気候政策の設計では、資金使途の透明性・公平性を通じた制度信頼の確保が支持獲得に重要。
📄 Abstract（原文）
Abstract Public support is central to the political feasibility of climate mitigation, yet the willingness to bear its financial costs may depend on factors beyond climate concern. Using the 2010 and 2023 waves of the Life in Transition Survey in 25 post-socialist countries, we examine how institutional trust and household expenditure are associated with willingness to pay (WTP), understood as giving part of one's income or paying higher taxes to combat climate change. Drawing on a stylized choice model in which this decision depends on the valuation of climate outcomes, the affordability of contributions, and the credibility of the institutions expected to use them, we estimate linear probability models with wave interactions and compare EU, post-Soviet, Baltic, and Balkan country groups. Both trust and expenditure are positively associated with WTP, but their relative importance shifted over time. Between 2010 and 2023, the income effect weakened while the trust effect strengthened, mainly in the post-Soviet, Baltic, and Balkan countries and much less in the EU group. These findings are robust to allowing the effect of climate concern to vary between waves and to logit estimation. Climate concern is strongly associated with WTP, yet concern alone does not ensure support for costly climate action. The political feasibility of financing mitigation also depends on institutional credibility and on public confidence that contributions will be used effectively, transparently, and fairly.
