Excited to release this policy brief exploring the college enrollment impacts of Massachusetts' recent dramatic expansions of free community college.

TLDR: The clear messaging and simple design of MassReconnect & MassEducate sparked substantial increases in community college enrollment.

Lotta meta-discourse this week about economics, the role of economists, who's paying attention, what they think of us, and if we're useful, etc.

For econ RCTs: Make your pre-analysis plan public in the AEA registry before submitting to a journal. Most people set them as private initially and never update that. If you're lucky, referees ask the editor to nag you. More often, no one knows what's prespecified, increasing chance of rejection.

It’s very expensive to monitor, sanction, and otherwise discourage countries from developing nuclear arsenals; it doesn’t seem wise to put any country in a position where they feel that type of arsenal is needed.

Why did that happen, what does it tell us, and what can we do next?

That’s what my forthcoming book, The Wage Standard, is about: how rules, norms, and power in the labor market shape who shares in growth. Coming out March 31. Pre-order here:

I don’t agree with lots in this article, but do agree it’s important to highlight that minimum wages can affect other aspects of job quality.

w/ Michael Davies and Jisung Park, I find higher minimum wages increase workplace injuries, likely via work intensification.

There is probably a way for the agenda setter to achieve dictatorship via a series of Condorcet cycles. This is plausible enough that I convinced chatGPT it was true and apparently the main reference is Gibbard Econometrica 1973

A memory imprinted on me from 25 years ago is Claudia Goldin (well on her way to a Nobel Prize) saying her salutation in cold emails to faculty is "Dear Prof. X". Maybe that's overkill, but I truly don't get the mindset of undergrads I've never met emailing "Dear Seema." Weakly dominated strategy.

The context window of an LLM limits how much can be read at once but you can have an initial search step or use multiple model calls to the LLM.

It’s also pretty easy to concatenate these and feed them into an LLM and ask the LLM questions about what is in the files.
