One of my empirical-work econ takes is that I think academia should be *more* open to publishing work based on best-we-can-do weak data, as long as there's really no other way to address the question and that work is very clear about what it can and can't actually say.

There are lots of cities where driving is difficult because of heavy traffic or nutty drivers. Portland is the only city that's extremely confusing to drive in and would be equally confusing if you were the only car on the road.

This episode is interesting as it's about a research group explicitly trying dozens to hundreds of quasi experiments, progressing only with the ones that "work", backing them up with a bunch of robustness tests, and then extrapolating a lot from the results. podcastaddict.com/freakonomics...

the "gotta hand it to em" the first time around was rapid approval and aided development of a vaccine that saved hundreds of thousands of lives, and this time it's "uhhh i guess they got rid of the penny"

As a guy whose name comes up when you search "many-analyst" now I've gotten quite a few referee requests now for papers where the "many analysts" are AI bots, or undergrads, or random people, rather than professional researchers.

For the second time since this baby has been born I am the only well person in a house of three other people. My life advice to all of you is to get a worse immune system

when you have a really good idea for a paper and a solid identification plan and access to data, it should be illegal for the data to be too noisy or small for your estimate to be any good

It is not until you have a child that you learn just how in your way it is possible for someone to stand

i enjoyed the Bad Guys movie but man the books are *awful*

i think there are a lot of people who would find it very hard to believe that the field of economics could produce this paper. and yet! Acemoglu is like the mainstreamest and most successful economist working today. some priors could use an update. www.nber.org/papers/w35336

it's wild when i think about how much better food is now than when i was a kid. so much more variety and quality. like, in my tiny hometown there's ethiopian and korean places, that's totally new. i can get a bagged salad cheaply at the grocery store and it's not wilted garbage.

I have my students using AI assistance for their ggplot coding in data viz this year and one thing I've noticed is that all AI chatbots are absolutely addicted to putting the x-axis labels on an angle.

I have a new working paper up today, "Partial Identification of Causal Effects that Vary by Setting" This looks at cases where you want to estimate the same causal effect across many settings (geographic, demographic, over time, etc.). arxiv.org/abs/2605.25483

Partial Identification of Causal Effects that Vary by SettingThe estimation of causal effects using quasiexperiments often relies on the use of unusual or serendipitous sources of exogenous variation. When the goal is estimating the same causal effects across m...arxiv.org
