They found that increasing the productivity of a worker’s peers meaningfully increased worker productivity, measured in kilograms of tea picked...

Researchers conducted a randomized evaluation in Mali to study the role of giving information to different people within a network in the spread of that information. People who were social and more closely connected to those who were trained had more information. Female farmers were less likely to...

Researchers partnered with CGIAR’s International Rice Research Institute (IRRI) to evaluate the impact of a flood-resistant rice variety on fertilizer use and crop yield in India. During floods, the flood tolerant seeds had a clear advantage over the traditional seeds. In non-flooded areas, there...
