Taxing Mechanical Engineers and Subsidizing Drama Majors – Marginal Revolution

In The Student Loan Giveaway is Much Bigger Than You Think I argued that the Biden student loan plan would incentivize students to take on more debt and incentivize schools to raise tuition with most of the increased costs being passed on to taxpayers through generous income based repayment plans. Adam Looney at Brookings takes a deep dive into the IDR plan and concludes that it’s even worse than I thought. Here are some of Looney’s key points:
Looney agrees that the incentive to increase tuition will apply to some graduate and professional programs but he thinks there is less room to increase tuition at undergraduate programs because borrowing is capped (currently! AT) at fairly low rates. But he offers an even more plausible but disheartening scenario that takes us in exactly the wrong direction.
Because the IDR subsidy is based primarily on post-college earnings, programs that leave students without a degree or that don’t lead to a good job will get a larger subsidy. Students at good schools and high-return programs will be asked to repay their loans nearly in full. Want a free ride to college? You can have one, but only if you study cosmetology, liberal arts, or drama, preferably at a for-profit school. Want to be a nurse, an engineer, or major in computer science or math? You’ll have to pay full price (especially at the best programs in each field). This is a problem because most student outcomes—both bad and good—are highly predictable based on the quality, value, completion rate, and post-graduation earnings of the program attended. IDR can work if designed well, but this IDR imposed on the current U.S. system of higher education means programs and institutions with the worst outcomes and highest debts will accrue the largest subsidies.
Looney does a back of the envelope calculation and estimates that typical graduates in Mechanical Engineering will on average get a 0% subsidy but graduates in Music will get a 96% subsidy, in Drama a 99% subsidy and Masseuses a 100% subsidy on average. This of course is exactly the wrong approach. If we are going to subsidize, we should subsidize degrees with plausible positive spillovers not masseues.

The problem is not just the subsidy but the encouragement this gives to create low-value programs:
Overall, the student loan program, as currently written, is looking to be one of the most costly, inefficient and unwise government programs of the 21st century. As I said in my first post, “fixing” the program is likely to drive ever more increasing intervention into higher education much as has happened with health care. My guess is that no one really thought this albatross through.
