Incredibly excited for my brand new class at Toronto Rotman this fall: Progress! Econ history + theory + history of tech/thought + philosophy on why rare orgs at rare times in rare places accomplish new things. Trying to put rigor onto an idea that is very much in the air. 1/3
Most people think “indirect costs” for government-funded scientific research have grown out of control (some universities charge >60% rates). In response, the Trump admin tried to cap them at 15%. But this whole debate rests on a false premise: While ***negotiated indirect…
Big thanks to @matthewesche and the @IFP team for spotlighting our work on #IndirectCostRecovery, a previously-arcane but tremendously important part of federal S&T policy. We hope it's helpful to improving understanding and charting a path forward.

We mapped who supports US STEM PhDs. Fed govt by far the main funder, esp in science for critical tech like AI and quantum. Less govt funding -> fewer graduates. Further details: drorshvadron.com/research/docto… Joint with @HansenZhang13, Lee Fleming and @daniel_p_gross

New @nberpubs working paper on the production of U.S. PhDs in science and emerging tech fields from @daniel_p_gross & colleagues nber.org/papers/w33944
📑New data, old debates: US government-funded R&D and patent policy @daniel_p_gross and Bhaven Sampat examine a dataset of US government-funded R&D patent records and analyse long-run patterns in US patent policy. ow.ly/IFjI50VHMjF #WorldIPDay
Reviewing the history of US indirect cost recovery policy, presenting new data on indirect cost recovery rates, modeling the effects of a 15 percent cap at the NIH, and evaluating tradeoffs across reform options, from @pierre_azoulay, @daniel_p_gross, and Bhaven N. Sampat…
Great as always from @daniel_p_gross and Bhaven. A friend was joking this week that their work shows so much innovation benefit across sectors from WW2 that the war is dangerously close to a net welfare benefit! Also see the correct point on linear model (more on this soon!)
The US WW2 medical research and development effort catalyzed postwar science, modernized drug discovery, and fueled the postwar National Institutes of Health — reshaping biomedical innovation for decades, from @daniel_p_gross and Bhaven N. Sampat nber.org/papers/w33457
Nope. This paper is about US academics 1900-1960! The present looks different. Asking people to stop drawing inference from these stats as if they're about the present & asking authors to put time period in their title and abstract! 🙏

I keep asking Claude about empirical evidence of the effect of automation on labor markets in the early 20th century. It suggests telephone operators as the best example (hooray). But it credits someone else (boo) but that someone else is Claudia Goldin (I'll take it)

Being an organizational economist in a strategy department, I am often puzzled by the little interaction that exists between these two fields. A new blog post written with a great group of colleagues to argue for more strategy in org econ, and viceversa cepr.org/voxeu/columns/…
Today on Forked Lightning - what do steam power and generative AI have in common? daviddeming.com/forked-lightni… Like steam, gen AI foreshadows big changes, but we probably need complementary innovation to unlock productivity growth in white collar jobs.
