Better Late Than Never: Macroeconomic Impact of Intermittent College Enrollment and Tuition Subsidies
Allowing people to enroll in college at any age, rather than only right after high school, accounts for about one quarter of the total welfare value of college in a life-cycle general equilibrium model; the gain is largest for people who start adult life with the least wealth. A nationwide tuition-free program raises the share with a bachelor’s degree from 25 to 78 percent and welfare by nearly 40 percent.
Abstract
People often delay starting college or temporarily leave college to work. To examine the welfare implications of intermittent college attendance, I incorporate flexible age-by-age college enrollment choice in a life-cycle model in general equilibrium. College serves as an investment device for the young and reduces risk for the old. Removing flexible access reduces the total welfare value of college by one quarter. Moreover, higher wealth and better human capital preparedness at age 18 incentivize early-age degree completion. However, accessing college at a later age matters more for those who are initially less advantaged. Thus, policies that alleviate financial costs generate considerable long-term welfare improvements.
What this paper shows
- In the NLSY79, people move between college and work 1.7 times on average; about two-thirds of bachelor’s degree holders had some interruption; 16 percent finished after age 30 and over 10 percent after 35. Only 9.3 percent of the sample completed a BA by 22. NLSY97 and CPS cohorts show the pattern is stronger in later cohorts.
- Removing flexible access (college only at 19, no return) lowers welfare by 3.7 percent of consumption and BA attainment by 28 percent; removing college entirely lowers welfare by 14.8 percent. Flexibility is therefore about one quarter of college’s gross welfare value.
- Individuals in the lowest wealth bin value flexible access about twice as much as those in the highest; about 60 percent of the lowest wealth bin could not finish a degree without it.
- Three channels: the general-equilibrium price channel is small; the investment value of college peaks at age 19 and disappears by about 24; the risk-reduction value emerges after 22 and peaks around 24, removing about 35 percent of the welfare cost of risk.
- A nationwide tuition-free program raises BA attainment from 25 to 78 percent and welfare by 39.6 percent, financed by an 8 percent higher lump-sum tax. A labor-income-tax exemption for part-time student-workers raises BA attainment by 17 percent and welfare by 1.6 percent, with gains concentrated at ages 24–30 and among low and middle endowment groups.
- With a market-based borrowing limit, flexible access accounts for 8.6 of the 9.1 percent welfare value of college — most of it.
What it does not show
- U.S. data; the NLSY79 follows cohorts born 1957–1964 (the paper checks NLSY97 and CPS synthetic cohorts and argues NLSY79 understates intermittence).
- The model abstracts from race, gender, geography and industry; a BA is defined as 16 years of completed schooling.
- Baseline uses a natural debt limit; tighter limits are robustness checks. Shocks take two values to keep computation tractable.
- Welfare is measured as consumption equivalence, not financial returns to college.
Context and definitions
- “Intermittent” includes delayed entry after high school, stopout (temporary exit) and re-enrollment, not only dropout.
- Initial conditions at age 18 are a human capital proxy (AFQT score) and a wealth proxy (average family income at 17–19), fed into the model as an empirical joint distribution rather than a fitted normal.
- The paper was circulated earlier under the title “Best Time for College? A Tale of Two Endowments”.
Data, method, contribution
- Data
- NLSY79 (1979–2016) for life-cycle enrollment, completion and initial conditions; NLSY97 and CPS ASEC synthetic cohorts for robustness; detrended CPS wages 1992–2016 for calibration.
- Method
- Overlapping-generations life-cycle model with incomplete markets in general equilibrium (Huggett, Ventura and Yaron 2011 lineage). Each year individuals choose full-time work, part-time work with part-time school, full-time school, or non-employment; human capital accumulates on the job or in college with a sheepskin effect; welfare measured as consumption equivalence (Mukoyama 2010). Model earnings dynamics match Guvenen’s RIP and HIP estimates.
- What is new
- The first paper to evaluate the welfare value of having access to college at each age, and to separate the investment and risk-reduction roles of college over the life cycle.
Who this is for
- Quantitative macroeconomists and macro-labor researchers
- Economists of education studying nontraditional students, stopout and adult completion
- Public finance researchers on tuition subsidies and tax incentives
- Higher-education policy analysts and journalists covering adult learners and free-college programs
Questions this paper answers
Is it worth going back to college later in life?
In the model, yes for many people, but for a different reason than at 19. Before about 24 college is mainly an investment that raises earnings; after that its value comes from reducing lifetime risk, and that insurance value is largest for people with little wealth.
What would free college do?
A nationwide tuition-free program in the model triples BA completion (25 to 78 percent of the population) and raises welfare by nearly 40 percent even after the taxes that fund it. A narrower tax exemption for part-time student-workers helps mostly people aged 24–30 from less advantaged backgrounds but yields a much smaller aggregate gain.
