This study assesses the impact of involuntary job loss on college persistence by leveraging different job-loss timings relative to a student's college enrollment decision. We find that job loss increases the probability that a working college student leaves college before attaining a degree, but access to short-term credit through credit card loans buffers this liquidity effect. By restricting credit supply to college students, the CARD Act of 2009 has inadvertently inhibited the ability of liquidity-constrained students to remain in college when their earnings unexpectedly fall, resulting in a stronger liquidity effect of job loss on college persistence over the last decade.
