Evaluations

Traffic is a significant concern in many rapidly developing and urbanizing countries, as it contributes to increased commute times, pollution, and fuel consumption. One solution to this challenge could be ride-sharing to reduce the number of cars on the road. In Malaysia and Singapore, researchers...

Researchers conducted a randomized evaluation to measure the impact of offering subsidies to connect to the power grid on the demand for rural electrification in Kenya. The study finds that demand falls rapidly as connection price increases, and that supply costs are very high.

Kenya, East Africa's largest economy, is struggling with an ageing energy infrastructure and low connectivity to the power grid. William Jack and affiliate Tavneet Suri (MIT) study the impact of off-grid solar power on small retailers in Nairobi.

In Uganda, researchers conducted a randomized evaluation to test the effectiveness of a program in which landowners were paid to not cut forest trees on their property. During the study period, landowners who were offered contracts to conserve forest cleared 4 percent of forested land, compared to 9...

In Malawi, researchers tested the impact of a subsidized tree planting program and tested whether allocating contracts randomly or through self-selection resulted in better program outcomes. Self-targeting outperformed random allocation of contracts in terms of tree survival and mitigated increases...

Researchers evaluated the impact of a residential energy efficiency program on energy savings and carbon emissions in the United States. They found that energy savings equaled only about half of the upfront cost of the program, which were far less than projected.

Researchers evaluated the impact of a reform to the pollution audit system in India, making auditors more independent, on the truthfulness of their reporting and the behavior of the firms they audited.

Researchers conducted a randomized evaluation in Cape Town, South Africa to measure the effect of prepaid meters on households’ electricity use and utility revenue. They found that prepaid meters led households to reduce their electricity consumption, but helped the utility company recover more...
