Curriculum Vitae

Dr. Katie Yewell joined the Department of Health Management and Systems Sciences as an Assistant Professor after completing her Ph.D. in Economics at Vanderbilt University. Prior to her appointment, she was also a Visiting Assistant Professor of Economics at Washington & Lee University and a Visiting Instructor of Economics at the University of Memphis.  Before completing her Ph.D., Dr. Yewell earned a Bachelor of Arts degree in Economics and Mathematics with a minor in Art History from Rhodes College in Memphis, Tennessee. Dr. Yewell has experience teaching classes on Introduction to Economics, Principles of Micro and Macroeconomics, Intermediate Micro Theory, Labor Economics, and Health Economics.

Dr. Yewell’s primary research interests are centered on understanding how health and education policies affect the decision making and wellbeing of children and families in the United States. Her dissertation studied how the rollout of universal free school meals impacted household food purchases, food insecurity, and teen health, and how the implementation of state laws requiring specific postpartum care standards at hospitals altered maternal behavior and time use. Her research also explores the heterogeneous effects of these policies and suggests spillover effects that are important to understand. Using rigorous empirical methodologies and thoughtful research design to estimate the causal effect of these contemporary policies informs how policymakers can address health and wellbeing outcomes for families.
