Check out our latest @vitalcitynyc.bsky.social piece on the role of states in regulating the proliferation of guns throughout the U.S. www.vitalcitynyc.org/articles/sta...

WSJ editorial page is wild these past few days

As I told the NYT, the recent deployment of the National Guard to select Democratic cities has been criticized for many incredibly valid reasons—including the fact that they are not a substitute for municipal police.

So much winning…. www.nytimes.com/2025/04/06/b...

Note that while “bias” will get your proposal flagged, “unbiased estimator” still appears to be on the table.

Added more gun researchers to this starter pack who joined BlueSky. Please share and lmk if you’d like to be added! @daniel-semenza.bsky.social @vitalcitynyc.bsky.social @meganranney.bsky.social @sonalirajan.bsky.social @thetrace.org @giffords.org @everytown.bsky.social go.bsky.app/G9zEmHs

Virginia Tech professor and poet, Nikki Giovanni, has died at the age of 81.

Nonetheless, I decided to leave in search of more freedom in terms of both style and content. And that’s all I’m going to say for now. My “so long and thanks for all the fish” column will appear next week. As for future plans, watch this space 2/

And it’s official. I’m immensely grateful to the world’s greatest news organization for giving me a platform all these years, and greatly appreciate the moving sendoff 1/ www.nytco.com/press/paul-k...

Welcome, @marthaolney.bsky.social!! Yes - @riacton.bsky.social has put together two women+ in econ starter packs.

How do firms respond when faced with climate shocks? Tarikua Erda's research examines how firms adjust physical capital investment and entry/exit decisions, providing key evidence to a long-standing puzzle. (Among other interesting projects: www.tarikuaerda.com)

I’m on the #EconJobMarket! I study labor, climate, entrepreneurship & innovation www.tarikuaerda.com/jmp My #EconJMP examines how how manufacturing firms respond to flooding. Do flooded firms build back better? Or do they suffer unrecoverable losses that weaken aggregate productivity? 🧵 1/n

ggplot alone will change your life.

Ed Glaeser and I wrote about the future of cities for the IMF. Fun topic to think about. www.imf.org/en/Publicati...

Hey #blacksky ‼️ So good to have left the bad place. Someone please share a starter pack!

I had an IV joke, but it’s getting pretty LATE.

Regression is a tool for making comparisons If you don't know / can't easily explain what comparisons you're trying to make, then you don't understand the regression you're running

The Race and Stratification Working Group at NBER will have its annual meeting on Friday, April 4, 2025! Dania Francis, Vicki Bogan, Ellora Derenoncourt and I are organizing the program. Submit your paper before the December 19, 2024 deadline! conference.nber.org/confsubmit/b...

Economists love using linear regression to estimate treatment effects — it turns out that there are perils to this method, but also amazing perks Come with me in this 🧵 if you want to learn about our now-published paper "Contamination Bias in Linear Regressions!" 1/ (Twitter rerun!)

Thanksgiving this year falls on the 28th, and 28 is a perfect number – meaning that it is equal to the sum of its proper divisors (28 = 1 + 2 + 4 + 7 + 14). So... I hope you have a truly perfect #Thanksgiving!!

Pleased to announce the Fourth Annual Scotland and Northern England Conference in Applied Microeconomics at the Crief Hydro Hotel in Perthshire on 6-8 May 2025! Our keynote speaker is @ludogazze.bsky.social More info & submission link at applied-microecon.wp.st-andrews.ac.uk/sane-worksho...

Contamination Bias in Linear Regressions -- out today in the AER! www.dropbox.com/scl/fi/x4bc1...

This seems wrong to me — at a minimum, using AI will let below-average doctors achieve average-ish levels of performance which would be a huge win even if there are no other benefits. www.pewresearch.org/short-reads/...

Everyone should give @vitalcitynyc.bsky.social a follow! A great urban policy journal with contributions from an impressive array of scholars and practitioners—including yours truly!

We built a starter pack (a work in progress) of some people who know a lot about New York City policy — and assorted others of interest. go.bsky.app/FCDEhhc

We've created a starter pack for all of the economics journals on Bluesky. Please nominate other journals to join the list. go.bsky.app/4kR21vX

We still have a relatively poor understanding of the relationship between evidence and policy. Program evaluation in particular is often motivated by a desire to make policy better. But how effective is program evaluation itself?Michelle Rao's JMP tackles this question. www.michellerao.com/research

2. Researchers *do* make many specification choices in the current environment. For example, functional form of the outcome (log vs. level?), set of controls (how many FE?), and the set of UNITS to include. We need to have a more balanced look at this trade-off.

Outstanding piece from @mattyglesias.bsky.social and complementary thread from Thomas below. Some recent CJ efforts involve (low-level) offenses that lack a social consensus on punishment—yet come with non-trivial social costs. Ignoring the costs doesn’t make it good policy or more “progressive.”

Really thoughtful thread here with useful concrete details

Folks! Our excellent BFI institute at UChicago is on here, give them a follow. They do an excellent podcast (the PIE) and host great conferences/workshops with open call-for-papers.

We wrote a short VoxEU column about our "Anonymity and Identity Online" paper and its broader implications. cepr.org/voxeu/column...

Nationwide, Black children are placed into foster care at higher rates than white children with identical potential to experience subsequent maltreatment — though less than in the past, from E. Jason Baron, Joseph J. Doyle Jr., Natalia Emanuel, and Peter Hull https://www.nber.org/papers/w33154

So excited to see my research on White women’s involvement with the business if American slavery in the New York Times! www.nytimes.com/2024/11/22/u...

Huge thanks to Kirabo - @appam.bsky.social has supported about 300 equity and inclusion fellows in recent years to broaden the pipeline of policy scholars and practitioners.

The most useful starter pack I've seen so far

In order to add some clarity on why the answer is just "use robust SE", here's a simulations that follow Abadie et al.'s paper "When Should You Adjust Standard Errors for Clustering?" This is pure random assignment of treatment. Cluster SE are way too big, and robust SE are close.

So what is everyone else doing for replication packages #EconSky? All #rstats empirical paper without too many computational bells and whistles.

I thought you guys were my friends?!?!

If you are interested in learning more about minimum wages, Attila Lindner and I have a new, up-to-date review of the topic, coming out in the Handbook of Labor Economics. Here's the @nberpubs working paper. Link: nber.org/papers/w32878

In the spirit of moving from the other place, I am re-advertising here the first episode of the podcast series: @florianederer.bsky.social on Killer Acquisitions. Listen at www.thevisiblehand.uk/episodes/epi...

Next up: Aarushi Kalra (aarushirita.github.io), experimenter extraordinaire! Aarushi works on development, political economy, and the digital platforms/AI. Her JMP studies a massive RCT run on one of India's largest social media platforms, which shut down the content personalization algorithm(!)

Interesting paper. Uses an intriguing shock to arrests (reductions in arrests after an on-duty officer death) to measure impact of ARRESTS on crime. Most studies measure impact of NUMBER OF COPS on crime. Get MUCH lower effects, suggesting police-crime reduction driven by PRESENCE >> arrests.

Greeting new Bluesky people! And welcome. Here are 100 ideas for reducing crime and improving safety without more police and prisons. johnkroman.substack.com/p/100-ideas-... And a summary version at Vital City: www.vitalcitynyc.org/articles/twe...

Welcome, @drlisadcook.bsky.social! 1st member of the Board of Governors on here. Given Fed comms policies, I doubt she can post anything much. But hopefully we can create some value for her in the #EconSky, #NumbersDay, and other conversations.

We’re here! Follow us for organizational updates and recommendations.
