Research

My research agenda is motivated by questions of how farmers make decisions in the face of risk and what tools are available to best mitigate those risks. In the future, I will address how environmental uncertainty and the heterogeneous risks of transportation and storage shapes investment decisions among crop choice and agricultural practices.

My research contributes to the literature on technology adoption to increase food security and income stability. Risk-mitigating technologies are important for farmers around the world who face uncertainty on many fronts. In my job market paper, I focus on drought risk in East Africa and an agricultural technology with stochastic advantages: Drought-Tolerant Maize. The tools I use in my dissertation, for example, mapping high resolution climate data to on-farm trial data and simulated yield estimates, give me a strong foundation for spatial analyses of climate change in any context.

Drought Tolerant Maize in Tanzania

Improved seed technology has the potential to improve quality of life for farmers in developing countries through increased yields and greater resilience to adverse climate events. However, adoption of improved seed technology is low, especially in Eastern and Southern Africa. My job market paper addresses the puzzling disconnect between promoted advantages and low adoption rates. I identify hurdles to adopting drought-tolerant maize because of challenges to learning and updating. This work is part of a larger randomized controlled trial evaluating the complementarity of index-based insurance with drought tolerant maize seed. This project is important in rural Tanzania, as many farmers neither have access to improved seed nor have the financial tools to consider risky new approaches. My research shows that the cultivation of drought-tolerant maize can stabilize household productivity and reduce food insecurity; however, those who could most benefit from the technology might be the slowest to adopt it—indicating the potential for effective policies to create large gains in welfare for farmers.

Drought-Tolerant Maize Response to Precipitation: Evaluating On-Farm Trial Data with High Resolution Climate Data

My AAEA 2017 poster on drought-tolerant maize response to precipitation in East Africa uses on-farm trial data from the International Maize and Wheat Improvement Center (CIMMYT).

Health Savings Behaviors in Burkina Faso: Results from a Framed Field Experiment

This paper explores household asset allocation under risk using the portfolio choice framework. Using simulations and data from a framed field experiment conducted in Burkina Faso, I find that the introduction of the risk-free savings instrument increases welfare for those at the bottom of the wealth distribution. In arid agricultural settings, households often have little access to resources to respond to negative shocks. Allocation strategies are important for household asset accumulation and policy for development of financial tools and institutions.

Subjective Expectations of Rice Price in Madagascar and Agricultural Productivity

For agricultural households, every economic decision bears some amount of risk, or the possibility of an adverse outcome. Decision makers use available information, including knowledge about risk, to determine their expectations of the future: uncertainty can weigh heavily in decisions. In the case of agricultural households, production and market risk and uncertainty can have real consequences for decisions. Understanding expectation formation and effects is crucial for successful development policy. Using household survey data collected in 12 villages across six communes around Lac Alaotra in Madagascar in 2004, I analyze the relationship between rice price expectations and labor input decision making.
