Recruitment of Farmers in the United States for Economic Field Experiments: What has CBEAR learned from running experiments with farmers? (with Collin Weigel, Paul Ferraro, and Kent Messer)
Economic field experiments provide insight into the potential of policies, particularly when conducted with professionals, such as farmers. However, the recruitment of farmers to experiments is challenging. Our research sheds light on what recruitment strategies are effective and cost-efficient for economists running agricultural field experiments. We evaluate recruitment strategies used in two large-scale experiments and find that monetary incentives and reminders are effective (if costly) for recruitment. Other strategies (i.e. public goods messaging) have little significant impact on response rate.

Less Rain, More Gain: Evaluating the On-Farm Yield Performance of Drought-Tolerant Maize in East Africa
Drought is a primary cause of crop failure, which has severe economic and welfare consequences for farmers in Eastern and Southern Africa. Improved crop varieties, such as drought-tolerant (DT) maize, can provide substantial improvements in yield level and variance. This paper assesses the performance of DT maize in On-Farm trials to identify the advantage of the DT trait under different drought conditions. I find significant heterogeneity in returns from the DT maize seed technology. This is important because variation in realized advantages might moderate the estimated large benefit from the technology.

The Impact of Availability Bias in Drought Expectations on Adoption of Drought-Tolerant Maize
A farmer decision to adopt a new agricultural technology like DT is based on his subjective beliefs about the likelihood of drought and the crop response to drought stress. Farmers’ expectations of drought likelihood depend on experience and cognitive biases. I develop a model of the adoption decision to show the role of information in expectations, giving insight into the limited uptake. I find that the comprehension of the DT maize characteristics is not the primary driver of adoption. I also find that a rosier expectation of the yield advantage or a more pessimistic expectation of future rainfall lead to higher adoption. However, between different comprehension frameworks there is negligible difference. When households are split by productivity, it is the lowest productivity households whose behavior is best predicted by expectations.
