Great exercise and apparently the answer is ‘no.’ Which is interesting given the magnitude of investments taking place. www.nber.org/papers/w34243

Perhaps of interest to folks with social science PhD programs: at Rotman, we added an experimental 3 session "tech stack" training in addition to the math boot camp. My lecture was "how to do reproducible, open, quick research", aka version control, LaTeX, AI. 1/2 kevinbryanecon.com/techstack.html

The Skill Inside the Task: How AI and Robotics Reshape the Structure of Work.

If AI and workers were strong complements, what would we see? The answer is pretty much what the initial data is showing

If AI and workers were strong complements, what would we see?, by @joshgans open.substack.com/pub/joshuaga... Does the latest data tell us AI is a substitute for human work? Nope. Is that comforting? Also nope. My comments on @erikbryn and co. (and @Noahpinion

#QJE Aug 2025, #3, “Structural Estimation Under Misspecification: Theory and Implications for Practice,” by Andrews, Barahona (@nanobarahona.bsky.social), Gentzkow, Rambachan (@asheshrambachan.bsky.social), and Shapiro: doi.org/10.1093/qje/...

With unique data from a large global manufacturer, we were able to study how product markups vary along the supply chain and over time.

One thing that surprised us: though manufacturer and retail markups bounce up and down, total (manufacturer + retail) markups are stable.

For example, we've recently learned that virtually all state-level DiD's are probably incredibly underpowered.

I've built a bunch of tools this summer to move my whole workflow to using things that are "pure text" so I can use AI on top. Here's the first: a modern paper reader. PDFs suck. Ugly, terribly interface, big files, fixed. I want papers that are adaptive, interactive, pretty. 1/5

Are you teaching behavioral economics this semester?

Just a reminder that I produced a 5-episode podcast series with Behavioral Grooves on the origins, growth, and future of behavioral economics.

AND we developed some helpful note-taking and discussion guides for use in the classroom...

GitHub - gregfaletto/fetwfePackage: Implementation of fused extended two-way fixed effects (Faletto 2024) Implementation of fused extended two-way fixed effects (Faletto 2024) - gregfaletto/fetwfePackage

NEW R PACKAGE: I created the {fetwfe} package to implement fused extended two-way fixed effects (FETWFE), my estimator for difference-in-difference under staggered adoptions.

You can install and use it by following the instructions on GitHub here: github.com/gregfaletto/....

Short thread:

From the fixest NEWS file: the new default VCOV is iid for all estimations. To change the default to the way it was, place setFixest_vcov(all = "cluster", no_FE = "iid") in your .Rprofile.

#rstats #econsky PSA: The next release of `fixest` will include some important changes (plus cool new features).

E.g. Fixed-effects regs will now default to 'iid' SEs rather than clustered. github.com/lrberge/fixe...

You can install and test drive the dev version from R-universe; see the README.

Very pleased that our local projections dif-in-dif paper is now out in the Journal of Applied Econometrics. Joint with @dgirardi.bsky.social, Jorda, and Taylor.

It's a tool that we think many applied economists will find useful (indeed many already have).
