In case anyone is interested, here is a new working paper on non-binary treatments with staggered interventions. Essentially, I show under what assumptions it is valid to estimate cohort x time dose-response functions. papers.ssrn.com/sol3/papers....

A Heterogeneous Slopes Approach to Difference-in-Differences with Non-Binary Treatments

I extend the approach of Wooldridge (2023, 2025) to allow for heterogeneous gains to treatment in the context of staggered interventions for non-binary treatmen

One aspect of research funding that it took me a while as a prof to appreciate: Someone who directs significant funding can shape the questions researchers investigate, *even researchers they don't directly fund*. Why? Because many researchers chase citations, and better-funded areas get cited more.

W/o getting drawn into the "seriously or literally" / "it'll never happen" trap, we need to stomp *hard* on the continuing effort to undermine Article 1 power of the purse by saying that this or that revenue stream makes something outside the normal budget process. 1/ www.nbcnews.com/business/eco...

Casual inference is the art of knowing why your estimate isn't casual, claiming it is anyway, and adding a bunch of "proofs" to your methods section to confuse reviewers. Bonus points for fancy notation like integral symbols or Kronecker products.

A good example of how politics often leads to second-best outcomes (at best). Political compromise means policy outcomes are sub-optimal (and sometimes worse than doing nothing). In this case either/or is /probably/ better than nothing, but this idea has problems. finance.yahoo.com/economy/poli...

"That said, it's good to see the president admit these numbers are so small that they couldn't have changed the outcome in 2020."

Talarico’s argument is simple: Stop treating marijuana like a crime. Legalize it. Regulate it. Tax it. Stop wasting police resources on low-level marijuana offenses. Clear the records of people whose lives have been derailed by nonviolent marijuana convictions.

The overwhelming right wing sentiment is that COVID was an engineered bioweapon that was also harmless. Trump overreacted to it by shutting down the country, then engineered a drive to create a vaccine that was the real bioweapon that killed millions, and it's Joe Biden's fault.

About ten years ago a sociology colleague came to my office asking how to calculate odds radios from their logit coefficients. I think my response of "why would you want to do that - why not just calculate average marginal effects for the probabilities in Stata (or SPSS, I forget)?" turned her off.

Yes. This point is not sufficiently recognized in the global imbalances debate. If you think your CA deficit is excessive and caused by factors outside your borders, you should tax or otherwise discourage capital inflows. Tariffs are a very blunt tool at best. +

Never minding the "I have a lot of sympathy for the changes under Trump" statement, this is really poor journalism. Numerous studies estimate the deaths and other harm to shutting down USAID. Just effing Google the research on topics you're asking about.

cops hate automated enforcement *because* its fair. They conceptualize their role not as punishing rulebreakers but punishing "bad people" (poors and minorities). They dislike red light/speed cameras because they wind up punishing "good people" for doing something they see as essentially harmless

”Tracking”, or splitting students into separate tracks which lead to vocations or college, is a common feature of other country’s education systems. The American rejection of this is, in my view, exceptional and laudable.
