PACKAGES

DISSERTATION

  • “Doubled SNAP Dollars and Nudges: An Analysis of Two Pilot Programs Aimed at Increasing the Purchase of Healthy Foods”
    • My dissertation used difference-in-difference-in-differences models and randomized controlled trials to measure the economic impacts of food policy interventions using transaction-level data from grocery stores and convenience stores. I analyzed controlled experiments to test hypotheses about consumer behavior and provided evidence-based recommendations to policymakers based on causal inference methods.
    • The first pilot program was a financial incentive called “Double Up Food Bucks” that targeted SNAP participants, encouraging fresh produce purchases by effectively doubling purchasing power. The second pilot program consisted of three behavioral nudges designed to increase banana purchases in convenience store environments.
