Clocking into Work and Out of Class: College Student Enrollment, Labor Supply, and Borrowing

This paper studies how college students choose their credit hour enrollment, labor supply, and borrowing, paying particular attention to the role of wages, financial resources and beliefs. To formalize these relationships, I construct a dynamic structural model where students choose their credit hours, work hours, and borrowing to maximize lifetime utility. I collect data from two sources to estimate the model: (1) a unique survey of Michigan State undergraduates eliciting their employment history, family financial support, beliefs about the returns to studying and beliefs about earning a high GPA, and (2) administrative data from the University. Estimates of the model suggest that students’ credit hour decision is inelastic with respect to changes in financial aid, tuition, beliefs, or wages. Students’ labor supply and borrowing decisions are responsive to changes in wages, and for a subset of students, changes in beliefs. I also conduct two counterfactual simulations, increasing the minimum wage and making college tuition free, and evaluate how these policy changes affect student decisions and outcomes.
