Improving electricity access in low-income countries is a challenging problem because of the high costs of grid extension and low demand for grid electricity in rural areas. This study elucidates these constraints by analyzing poor households' willingness-to-pay for different types of...

This study uses a contingent valuation approach to value the willingness-to-pay (WTP) for improved service experienced by households in Nepal following the end of the country's load-shedding crisis of 2008-2016. Using a detailed survey of grid-connected Nepali households, the authors calculate...

Cost-effective allocation of conditional cash transfers (CCT) requires identifying recipients with low opportunity costs who might change behavior. This paper develops a low-cost approach for improving program implementation by using a stated preference, referendum-style survey question to...

This study uses a choice experiment among 2,000 workers in Bangladesh to elicit willingness to pay (WTP) for job attributes: a contract, termination notice, working hours, paid leave, and a pension fund. Using a stated preference method allows calculation of WTP for benefits in this setting,...

The Amazon rainforest, the world's largest tropical rainforest and an important constituent of the global biosphere, continues degrading by rapid deforestation, which is expected to continue despite policies to prevent it.

Does financial compensation for providing environmental conservation, improve the food security of the rural poor in the drylands of Sub-Saharan Africa? This paper explores this question using data from a randomized controlled trial of a large scale reforestation implemented by the Government of...

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...

The Amazon rainforest, the world's largest and most biodiverse, represents a global public good of which 15 percent has already been lost. The worldwide value of preserving the remaining forest is today unknown. A "Delphi" exercise was conducted

Air pollution has major health impacts on people living in Ulaanbaatar. The excessively high particulate matter concentrations, especially in the winter and in the ger areas, increase the incidence of heart and lung diseases, and lead to premature deaths. Improving air quality management in...

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...
