Former Secretary of State Hillary Clinton has adopted one of Sen. Bernie Sanders' signature campaign pledges: free in-state tuition at a public college or university.
Under an earlier plan, Clinton had merely promised that families would not have to borrow for college tuition, but parents and students would have contributed what they could afford. To reduce the cost of free tuition — estimated at $750 billion over 10 years if all students were eligible — the new Clinton-Sanders plan is limited to families earning less than $125,000 per year.
Details have not been released, but the plan is likely to resemble the College for All Act (SF 1373) that Sanders introduced last year. Sanders' website claims "this is not a radical idea. … In fact, it's what many of our colleges and universities used to do. The University of California system offered free tuition at its schools until the 1980s."
The free-tuition plan makes political sense for Clinton as an appeal to Sanders' young, left-leaning supporters. But is it economically sound? Unfortunately, the proposal falls short for three reasons: 1) it is regressive, 2) it rewards bad behavior and 3) it inevitably would lead to federal micromanagement of public colleges and universities.
Free college tuition would be "regressive," meaning that the benefits would flow mainly to students from upper-income families. Let's look closely at this surprising conclusion. Even if something is free, it may not be used equally by people from different backgrounds. The users of higher education, particularly expensive higher education at elite universities, tend to come from upper-income families.
This was documented by Lee Hansen and Burton Weisbrod, two economists at the University of Wisconsin who studied the distribution of costs and benefits from California's free-tuition policy (the poster child for Sanders' plan). The state subsidies in 1964 varied dramatically across the three branches of the higher-education system, with the prestigious University of California campuses such as Berkeley receiving a much larger subsidy per student than state colleges and junior colleges. Since attendance at those elite universities was highly related to income, the subsidies disproportionately benefited students from upper-income families.
Hansen and Weisbrod compared the subsidies with state and local taxes paid to finance free tuition in California. The results showed that families with children enrolled in public higher education received positive transfers (subsidies minus taxes paid) that grew with average family income.
The same pattern persists today: Undergraduate students at more costly colleges come from higher-income families. According to the National Postsecondary Student Aid Study in 2011-12, 54.2 percent of dependent students enrolled in two-year colleges came from families earning less than $60,000 per year, while only 38.4 percent of those attending four-year institutions that grant doctorate degrees (such as the University of Minnesota, University of Michigan and Berkeley) came from such families.
