Does linking teachers' pay to students' test performance improve educational outcomes, or just increase “teaching to the test”? This study examines the effects of a teacher incentives program on both teacher behavior and student test scores in Kenya. Student test scores increased significantly during the study period, but evidence suggests that this improvement came through test-preparation sessions outside of normal class hours.
New agricultural technologies, such as high-yielding crop varieties, offer the promise of increased productivity, but adoption of these technologies has often been slow, particularly in sub-Saharan Africa. In Sierra Leone, researchers are testing whether price subsidies and agricultural extension training can reduce the costs of early adoption, and whether using the improved seed varieties will ultimately benefit poor farmers.
Political clientelism is often deemed to undermine democratic accountability and representation. This study argues that economic vulnerability causes citizens to participate in clientelism. Researchers tested this hypothesis with a randomized control trial that reduced household vulnerability through a development intervention: constructing residential water cisterns in drought-prone areas of Northeast Brazil.
This project will evaluate the impact of commitment contracts and reminder messaging on savings behaviors among low- and medium-income credit union members in Washington DC. Traditional financial products which dominate the consumer finance market tend to operate under the assumption that consumers act in a rational manner and fail to take into account cognitive biases which can impede the realization of financial goals.
This study assesses the willingness of households in Northern Ghana to purchase a ceramic water filter. The Kosim filter is sold by Pure Home Water (PHW), a Ghana-based NGO, and has been demonstrated to be highly effective at improving water quality without needing electricity. We will also measure the health effects of household-level water treatment in areas with high waterborne disease loads.
Access to transportation is generally considered to be a fundamental determinant of economic growth and a significant factor in an individual’s health, schooling, and economic status. In Malawi, researchers studied the introduction of a daily minibus service that connected five rural villages and the nearby market town. Although a majority of households used the new bus service, demand was very sensitive to price and was never sufficient to cover operational costs.
Little empirical evidence exists on the effectiveness of business training and support. In particular, the extent to which such a support program might raise revenues and augment survival rates of new enterprises is unclear.
How effective is vocational training in Western Kenya? This study leverages a longitudinal survey to examine the impact on individuals with different childhood and background characteristics. Individuals are invited to apply (and then randomly selected) for a tuition voucher. The study will also measure the demand for vocational training, and the difference between public and private sector training institutes.
Can communicating beneficiary feedback to donors augment philanthropic gifts or improve the operations of charitable organizations?
There is substantial evidence that media sources have identifiable political slants, but there has been relatively little rigorous study into the impact of media on political views and behaviors. IPA designed a natural field experiment to measure the effect of exposure to newspapers on political behavior and opinion.
