Researchers in northern Ghana evaluated the underlying reason for underinvestment by examining the relative effectiveness of cash grants and insurance grants in improving crop yields. Results suggest that uninsured risk, rather than a lack of capital, was the primary constraint on investment...

In Western Kenya, researchers evaluated an SMS intervention whereby a large-agribusiness sent farmers with whom they contracted timely reminders on agricultural tasks to be completed. The SMS intervention was a cost-effective means of increasing yields, farmer revenue, and company profits. However...

Researchers conducted a randomized evaluation to test whether the position of a trained lead farmer within a community’s social network affected other farmers’ decisions to adopt a new agricultural technology in Malawi.

While researchers found a meaningful reduction in smoke inhalation in the first year after households received an improved stove, there was no effect over longer time horizons. The difference between the laboratory and field results is due to households’ revealed low valuation of the stoves...

Researchers in Ghana introduced financial literacy training and crop price insurance to determine their impact on farmers' willingness to take out loans and make long-term investments. Results show that farmers who received the training and insurance were only slightly more likely to borrow and make...

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. Increasing their independence made them more likely to report the truth about industrial plants’...

In Malawi, researchers examined the effect of bundling rainfall index insurance with a credit program on farmers’ demand for credit. They found that bundling insurance with credit reduced the demand for credit, from 33 percent for credit alone to 17.6 percent for the bundled product.
