Can the Trump administration make college cheaper?

The Trump administration is implementing a new policy to cap federal student loans for graduate students, hoping to force colleges to lower tuition prices. The plan is based on the Bennett Hypothesis—a 40-year-old economic theory claiming that reducing student borrowing capacity will pressure schools to reduce costs. NPR Education Correspondent Cory Turner explores whether this hypothesis holds up under decades of actual data.

Curious

The Bennett Hypothesis: Loan Caps Force Tuition Cuts
Limiting federal student borrowing capacity will force colleges to lower tuition prices because schools lose revenue if students can't afford to pay.

Highlights

Counterintuitive Policy Logic: Restricting Access to Improve Affordability
The administration argues that giving students less money to borrow will ultimately make college more affordable by forcing tuition prices down.

Editorial

Federal Policy as Economic Leverage on Higher Education
The Department of Education's control over student lending gives the federal government extraordinary power to reshape institutional behavior in higher education.
Testing a 40-Year-Old Economic Theory With Real Data
The Bennett Hypothesis was proposed four decades ago without empirical backing; now a major federal policy rollout provides an opportunity to test whether the theory actually works.
