A guaranteed tuition offer shifted low-income students into a top university. The students graduated sooner and earned more selective degrees, narrowing the gap with higher-income peers, from Burland, Delaney, Dynarski, Leu, Libassi, Michelmore, Owen, Quiroga, and Salinas www.nber.org/papers/w35434

I'm on the #EconJobMarket! I study how policies and childhood environments shape outcomes of low-income & vulnerable kids. In my JMP, I study the effects of allowing youth who would have aged out of foster care at 18 to stay until 21—offering support their peers not in foster care get from parents.

New at @pseocoalition.bsky.social, @julia-turner.bsky.social & I have a new report on grad school debt & earnings over the medium term. For some key professional fields (🩺⚖️🦷💊🐾), we show the varied patterns both within & across areas of study, looking at the first decade of earnings after graduation
Scatter plot comparing median program debt (x-axis, $50k-$300k) vs 10-year cumulative earnings (y-axis, $0.5M-$2M) for professional programs. Medicine MD programs (pink squares) cluster in upper right with high debt ($150k-$250k) and high earnings ($1.4M-$1.8M). Law programs (blue circles) cluster in the bottom left corner with lower debt and lower earnings, though some elite programs show medicine-level earnings and somewhat higher debt than other law schools. Veterinary Medicine (green diamonds), Dentistry (plus signs) and Pharmacy (X marks) are distributed across middle ranges of earnings, but across wide ranges of the distribution of debt, with almost all pharmacy programs having lower debt than almost all dentistry programs. Physical therapy and veterinary programs have law-like earnings (between half a million and a million over 10 years), and while PT has law-like debt as well, veterinary debt is generally much higher and closer to medical school.

Wanted to highlight a new report we have just released at the Office of the Chief Economist at ED: "An Overview of Graduate Borrowing and Outcomes." Below are a few graphs that might entice you to read more. First: distributions of annual borrowing for top 25 credentials in terms of annual volume
A stacked density plot showing distribution of annual graduate program borrowing in 2019 across different programs. Professional programs like dentistry and medicine have highest borrowing ($80k-120k), while master's programs in education and business typically borrow much less ($20k-40k). Programs ordered by average borrowing amount.

There's a famous political scientist who often says all results of formal models are obvious (which I take to be a cousin of this claim). There's a story of a junior theorist setting up the model in a talk, stopping, and saying, "This would be the moment to tell me the results, if they're obvious."
