A significant portion of the world's forests that are eligible for Reducing Emission from Deforestation and Forest Degradation, known as REDD+, payments are community managed forests. However, there is little knowledge about preferences of households living in community managed forests for REDD+ contracts, or the opportunity costs of accepting REDD+ contracts for these communities. This paper uses a choice experiment survey of rural communities in Nepal to understand respondents' preferences toward the institutional structure of REDD+ contracts. The sample is split across communities with community managed forests groups and those without community managed forest groups to see how prior involvement in community managed forest groups affects preferences. The results show that respondents care about how the payments are divided between households and communities, the severity of restrictions on firewood use, the restrictions on grazing, and the fairness of access to community managed forest resources as well as the level of payments. The preferences for REDD contracts are in general similar between community managed and non-community managed forest resource respondents, but there are differences, in particular with regard to how beliefs influence the likelihood of accepting the contracts. Finally, the paper finds that the opportunity cost of REDD+ payments, although cheaper than many other carbon dioxide abatement options, is higher than previously suggested in the literature.

This paper informs the national and international policy discussions related to the adoption of the United Nations Reducing Emissions from Deforestation and Forest Degradation Programme. Effective program instruments must carefully consider incentives, opportunity costs, and community interactions. A choice experiment survey was applied to rural Ethiopian communities to understand respondents' preferences toward the institutional structure of the program contracts. The results show that respondents have particular preferences about how Reducing Emissions from Deforestation and Forest Degradation programs are structured with regard to the manner in which the payments are divided between the households and the communities, the restrictions on using grazing land, and the level of payments received for the program. Surprisingly, restrictions on firewood collection do not significantly impact contract choice. The paper further analyzes the structure of the preferences by using attribute interaction terms and socio-demographic interaction terms. The analysis finds significant regional variation in preferences, indicating that Reducing Emissions from Deforestation and Forest Degradation should be tailored to specific regions. Finally, the marginal willingness to pay for attributes is calculated using the traditional preference space approach, as well as the more recent willingness-to-pay approach.

This paper presents the three-year impacts of an improved biomass cookstove on child and adult health in rural Ethiopia. After near complete stove adoption during an initial one-year randomized controlled trial, 60 percent of treatment households continued to use the improved stoves three-years on and experienced reductions in hazardous airborne particulate matter. The study finds that treatment status is associated with a precisely estimated 0.3-0.4 standard deviation improvement in height-for-age of young children exposed during their first years of life, compared with a control group of households that never used the improved stove. This is a substantial effect with implications for greater health and well-being throughout the life course. However, the study finds no changes in the respiratory symptoms or physical functioning of older children and adult cooks in treated households relative to control households. The results advance understanding of the health impacts of hazardous air pollution while also refining the design and implementation options for interventions geared toward improving well-being in similar environments.

This paper investigates household preferences for improved cook stoves using a choice experiment administered in rural Ethiopia, and the cost-effectiveness of an improved stove for reducing global greenhouse gas emissions. In Ethiopia, about 96 percent of household energy demand is fulfilled by biomass. Improved stoves use less firewood and produce less smoke, and they have been touted as a way to reduce greenhouse gas emissions and health effects from indoor air pollution, as well as to improve forest conservation. Although there are many studies on the adoption of improved stoves, there is limited information on the willingness to pay for particular attributes of stoves, information that is vital for designing effective stoves and improving stove adoption. The paper finds that households have a positive willingness to pay for the durability, fuelwood use reduction, smoke reduction, and cooking time reduction of improved stoves. It also shows that the stove used in this experiment can be cost-effective for reducing greenhouse gas emissions, which suggests that programs providing payments for reducing greenhouse gas emissions could strengthen stove adoption if they are well implemented. The main reason the stoves are not being adapted is the lack of availability, which is a key message to policy makers.

There is a growing effort in the non-market valuation literature toward better understanding of the stability and evolution of preferences over time. The study uses a novel approach combining a repeated choice experiment with a randomized controlled trial on stove adoption in Ethiopia to analyze the stability and evolution of preferences. The treatment group in the randomized controlled trial received an improved fuelwood stove with less fuelwood use, whereas the control group continued to use traditional cooking methods. Respondents were given the exact same choice questions in 2013 and 2016. The study began with 504 households in 36 communities in 2013, and 486 of the same households participated in 2016 (a 96 percent retention rate). The results show that preferences of the respondents from the control group are stable over the study period, while preferences of the respondents from the treatment group evolve. Moreover, households in the treatment group still using the stoves have significantly higher willingness to pay for all the stove's attributes in 2016 compared with 2013, indicating how longer experience can increase the willingness to pay for technology with environmentally preferable attributes.
