ネパールの都市部で、電気調理器の導入に対する補助金の効果をランダム化比較試験で検証。補助金は導入率を23ポイント、対応調理器具の購入を41ポイント引き上げたが、情報提供のみでは効果が小さかった。計画者のモデルを用いて最適な補助金水準を推定している。
English
This study uses a randomized controlled trial in urban Nepal to evaluate policies promoting electric stove adoption. Subsidies increased adoption by 23 percentage points and cookware purchases by 41 points, while information campaigns had little effect. A planner model estimates optimal subsidy levels under fiscal and energy security constraints.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策では、家庭部門の脱炭素化（例：電化促進）やエネルギー安全保障の両立が課題。本論文のRCTによる政策効果の実証は、日本の補助金設計や情報提供の効果検証に示唆を与える。
In the global GX context
This paper provides rigorous experimental evidence on energy transition policies, relevant to global efforts in electrification and subsidy design. It highlights the importance of financial incentives over information, informing policy frameworks like the EU's energy transition initiatives and developing countries' clean cooking programs.
👥 読者別の含意
🔬研究者:Provides causal evidence on subsidy effectiveness and a modeling framework for optimal policy design.
🏢実務担当者:Insights for designing subsidy programs to promote electric appliance adoption.
🏛政策担当者:Evidence that subsidies are more effective than information campaigns for energy transitions.
📄 Abstract（原文）
A central challenge in the global transition to cleaner energy is how governments can design policies that deliver large social benefits while facing trade-offs in energy security, fiscal costs, and household adoption frictions. We study this question in urban Nepal, where cooking is dominated by imported LPG, but abundant hydropower makes both large-scale electrification and improved energy security feasible. We embed household adoption decisions in a model of a planner balancing fiscal, fuel supply, and energy-security considerations, and estimate its key parameters using a scalable randomized controlled trial in Kathmandu Valley. Subsidies had large effects, increasing electric stove adoption by 23 percentage points and compatible cookware purchases by 41 percentage points. In contrast, information treatments highlighting cost or health benefits alone had little impact. Using detailed survey and electricity billing data, we find substitution away from LPG toward electricity, with meaningful household heterogeneity. Disciplined by these experimental estimates, the model evaluates counterfactual targeting rules, and estimates optimal subsidy levels under different macroeconomic conditions.
