I am an applied microeconomist working at the intersection of environmental and development economics. My research focuses on the health and human capital impacts of exposure to environmental harms, particularly air pollution. I also have work on the role of information frictions in economic development. A cross-cutting theme in my research is how behavioral economics can yield insights into how people adapt to a changing environment.
My undergraduate studies were in Economics and Religion (with a focus on Buddhist Philosophy) at Middlebury College. My senior thesis there focused on the role of partisan preferences in taxation and was published in the Journal of Public Economics. I studied abroad in Nepal as a college student and have ongoing fieldwork there as part of a J-PAL funded RCT. Prior to UC Davis, I worked at the Busara Center for Behavioral Economics in Nairobi, Kenya, and then spent four years at Mathematica Policy Research, conducting international development impact evaluations in global health, energy infrastructure, and social protection.
I am on the job market in the 2026-2027 academic year and can be reached at msbrooks@ucdavis.edu. Here is my CV and here is my job market paper.

- The Pollution–Productivity Curve: Non-Linear Effects and Adaptation in High-Pollution Environments (Job Market Paper)
With Faraz Usmani. Submitted.
This paper provides novel evidence that workers in a high particulate matter air pollution setting partially adapt to chronic exposure, but that adaptation does not offset cumulative harm. Using ball-by-ball data from professional cricket in India, we find that a 10 µg/m3 increase in same-day PM2.5 reduces performance by about 1 percent. Effects are non-linear, with the largest marginal damages above approximately 50 µg/m3. Workers with the highest past exposure are roughly 40 percent less sensitive to acute shocks than those with median exposure histories, consistent with adaptation. Nevertheless, chronic exposure degrades performance by more than this adaptation offsets.Invited Seminars: Indian Statistical Institute, Delhi · University of Massachusetts, Amherst · Middlebury College

With Shotaro Nakamura and Collin Weigel
This paper shows that administrative hassles in an environmental public benefit program application shift the applicant pool away from the intended beneficiaries. In a randomized controlled trial with 100,000 households in California, we randomly vary the subsidy rate (0-100%) and administrative hassles in an application for a subsidized air purifier. Lowering the subsidy rate lowers application rates non-linearly, with larger marginal reductions at higher subsidy levels. Hassles substantially reduce the application rate. We find suggestive evidence that these hassles disproportionately screen out intended beneficiaries: the longer form deters below-poverty-line applicants, and the residence requirement deters those with above-median particulate exposure.Conferences: APPAM 2026 (scheduled) · AAEA 2026 · AFE 2025 · UC Berkeley/Davis Giannini Student Conference 2025, 2026 · Funding: California Air Resources Board · PAP: AEA RCT Registry
- Strengthening Women’s Livestock Cooperatives in Nepal with an Innovative Technology Bundle
With Travis Lybbert, Nick Magnan, Conner Mullally, and Bhola Shrestha
This paper shows that relaxing market information constraints raises sales and revenue for smallholder goat producers in rural Nepal. In a 2×2 cluster-randomized factorial experiment among approximately 70,000 farmers in 93 cooperatives, we cross-randomize a market linkage app for producers with a continuing education app for community animal health workers. The education app improves health workers' knowledge but does not shift goat health within our study period. We do not detect any additional effects from bundling the two apps. Back-of-envelope calculations suggest the market app returned over three dollars in additional farmer revenue per dollar of setup cost.Conferences: AAEA 2026 · Funding: J-PAL DAISI · PAP: AEA RCT Registry
