We conducted an experiment providing fertilizer grants to female rice farmers in Mali. We found that women who received fertilizer used both more fertilizer and more complementary inputs such as herbicides and hired labor. This shows that farmers respond to an increase in one input by...

We designed and tested a voluntary commitment product to help smokers quit smoking. The product (CARES) offered smokers a savings account in which they deposit funds for six months, after which they take a urine test for nicotine and cotinine. If they pass, their money is returned; otherwise,...

In a field experiment in Uganda, we find that demand after a free distribution of three health products is lower than after a sale distribution. This contrasts with work on insecticide-treated bed nets, highlighting the importance of product characteristics in determining pricing policy. We put...

Pricing policy for any experience good faces a key tradeoff. On the one hand, a price reduction increases immediate demand and hence more people learn about the product. On the other hand, lower prices may serve as price anchors and, through a comparison effect, decrease subsequent demand. This...

In much of the developing world, many farmers grow crops for local or personal consumption despite export options which appear to be more profitable. Thus many conjecture that one or several markets are missing. We report here on a randomized controlled trial conducted by DrumNet in Kenya that...

The investment decisions of small-scale farmers in developing countries are conditioned by their financial environment. Binding credit market constraints and incomplete insurance can reduce investment in activities with high expected profits. We conducted several experiments in northern Ghana in...

The investment decisions of small-scale farmers in developing countries are conditioned by the farmers’ financial environment. Binding credit-market constraints and incomplete insurance can reduce investment in activities with high expected profits. We conducted several experiments in northern...

We partnered with a micro‐lender in Mali to randomize credit offers at the village level. Then, in no- loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with...
