Does Providing Improved Biomass Cooking Stoves Free-of-Charge Reduce Regular Usage? Do Use Incentives Promote Habits?
通过实地实验和实时电子监测，研究免费发放和改进型生物质炉灶的使用激励对埃塞俄比亚家庭使用强度的影响，发现免费分发在促进短期采用和长期规律使用方面至少与收费或激励措施同样有效。
This paper uses a field experiment and real-time electronic stove use monitors to evaluate effects of monetary treatments on usage intensity of one of the most important improved biomass-burning cookstoves promoted in Ethiopia.Understanding whether, how much and why improved stoves are used are important, because use frequency critically determines fuelwood savings and related benefits.We find that distributing stoves free-of-charge is at least as effective for promoting shortrun adoption as requiring payments or offering usage incentives.Free distribution is most effective at promoting high and increasing levels of longer-run regular use.
