This dissertation consists of three chapters on the economic determinants of health, specifically those related to the pathways of nutrition and government nutrition assistance policy. I evaluate the Community Eligibility Provision’s (CEP’s) effects on child weight outcomes in my first two chapters, a program that allows certain schools to offer universally free school meals to all students. My first chapter uses child-level data from a nationally representative survey which follows a single sample of children from Kindergarten to fifth grade. I use these data to identify the effect of attending a CEP school on outcomes of child weight. I find that CEP school attendance increases a child’s Body Mass Index (BMI) percentile score, decreases their likelihood of falling within the healthy weight range, and increases their probabilities of being overweight and obese. In my second chapter, I utilize school-level data for the universe of K-12 schools in the state of Georgia. My data set includes aggregate measures of child weight including average child BMI and the percentage of students attending a school who fall within the healthy weight range. I find that adopting the CEP decreases average child BMI and increases the percentage of healthy weight students. Differences in the results of Chapters 1 and 2 highlight the likelihood that the CEP’s effects on child weight may vary by location and student characteristics. Finally, my third chapter proposes a new model for the measurement of food security. Specifically, I construct a Bayesian Graded Response Model (BGRM) which can be used to measure food security with responses to the United States Department of Agriculture’s core Food Security Module (FSM). I use a simulated data exercise to evaluate the performance of my model in a controlled environment. I find that my model properly retrieves the set of data generating parameters. Comparing the performance of my model to the most commonly used measure of food security, the FSM scale, I find that my model more accurately assigns the food security status of households in all cases.
