If you missed the webinar last Friday on wood burning/harvesting, forest management, and carbon implications, the RSVP link below now has the slides and the recording. Feel free to download the papers at the link below as well.

🧵Words matter. We are experiencing a flood of unrestrained antisemitism and hate speech. As a survivor of the Pittsburgh synagogue attack, I know where this leads. We have to stop tolerating and normalizing antisemitism and all forms of bigotry.

Does burning more wood lead to more forests & help the climate? In a new Nature paper, WRI & Yale researchers show such claims rely on flawed accounting and models, and misinterpret underlying studies. Read the papers: rdcu.be/eNkXX RSVP to a webinar 10/31, 9:30 ET: hub.wri.org/events/2025/...

"Without the Musk partisan effect, Tesla sales between October 2022 and April 2025 would have been 67-83% higher, equivalent to 1-1.26 million more vehicles. Musk’s partisan activities also increased the sales of other automakers' electric and hybrid vehicles 17-22%..."

“Agriculture is really our biggest environmental problem.” A nice overview of my hot takes on organic, grass-fed, and other fake solutions. Props to @envdefensefund.bsky.social for standing by the science when a lot of green groups are following the zeitgeist. worth.com/sustainable-...

America’s advantage in science made us rich, and kept us powerful. It’s why we have the most innovative companies, the most successful tech sector and the mightiest military. Why is Trump trying to slaughter the golden goose? wapo.st/41iUzAW

We couldn't not rate this classic early DAG by our beloved collective granddagy, Sewall Wright. 14/10. Ten for the DAG, plus one for each cute guinea-pig node. From Wright (1920) "The Relative Importance of Heredity and Environment in Determining the Piebald Pattern of Guinea-Pigs"

For a more reliable source to answer "what was the most foundational work in weak identification (and much more) over the past several decades?" I can think of no better place than the Cowles 2025 Conference on Econometrics Celebrating Don Andrews that I will attend next week.

Wow. This is the paper I have been waiting for. Mobile apps are brain rot, with meaningfully bad economic consequences for those who overuse them.

Next week, I'm teaching another round of my online Mixtape course on BLP-style demand estimation! The sessions are hands-on and last time we had a ton of great questions. Sign up here: www.mixtapesessions.io/session/dema...

Every city that has driverless cars before driverless metros needs to hang its head in shame.

The other day a student asked me about the prevalence of insider trading in prediction markets. I now have an answer.

In my life I've seen treatments for AIDs developed, vaccines for Ebola and malaria, and now this. Medical science is one is the areas that still consistently seems to make these miraculous advances and I'm genuinely grateful to everyone involved. www.bbc.co.uk/news/article...

Absolute respect for the staff at the stats agencies who keep the innovation going, despite the challenges. These new data will be helpful. Do not take this for granted.

The vibes at YIMBYtown were amazing. More than any other conference I’m familiar with, most people at YT are doing meaningful work on the ground and attend because they want to become more effective. Pragmatic, optimistic and energetic—just what we need right now. Let’s build more homes, y’all!

ND Gov. Kelly Armstrong at @yimbytown.bsky.social : on any policy change, 20% of people will be cranky & loud against, 80% are supportive but busy living their lives & don’t speak up. Ignore the 20%. Turn off your social media. Find a compelling emotional hook to engage the silent 80%.

“American colleges, especially the most selective ones, are confronting the dual problems of rampant grade inflation and declining rigor,” @rosehorowitch.bsky.social writes. “Teacher evaluations are a big part of how higher education got to this point.”

SB-79 HAS PASSED THE SENATE AND IS ON ITS WAY TO THE GOVERNOR’S DESK

This is not true. Blackstone owns 0.06% of the single family homes in America. There is no market where they own more than 1% of the homes. Nobody has a monopoly on housing. 2/3 of American households own their homes and rental housing is a VERY diversified and competitive industry.

Dan Sacks and I are looking for a postdoc to work on Medicaid evaluation projects at UW-IRP. See posting: hr.wisc.edu/postdoc-and-... . Email your resume and cover letter to Tim Connor at [email protected]. For any questions regarding the position, please contact Dan Sacks at [email protected]

Induction stoves are quieter, cooler, and produce less toxic pollution than gas. On the other hand, they also cook better, as a growing number of professional chefs recognize.

Seems bad

This move to import more U.S. corn ethanol will increase GHG emissions, rather than decreasing them.

I now too have a "professional announcement." I have known it for quite some time now, but only from today on this is really, legally official: I am now Professor of Economics at the Department of Economics at the University of Michigan (Ann Arbor campus), @umich.edu

Are the mRNA vaccines incredible? YES! Are the mRNA vaccines perfect? No. Have the mRNA vaccines saved millions of lives? YES! Can we make the mRNA vaccines even better? YES! Can we use mRNA vaccine technology to prevent and treat many other diseases? YES! Fund mRNA research!

Truly great news as NYC moves forward with this subway extension. But the cost remains mind-boggling. We're talking $1.97 b for 1.6 mi of new tunnel, space for 125th St station, & upgrades to 0.5 mi of existing tunnel. In Paris, a €2.5 b contract awarded last year will build 10.6 mi of new tunnel.

Hello #econtwitter community: if any of you has been teaching any of my papers, would you mind shooting me a DM? I would hugely appreciate that 🙏 and thanks in advance!

This is exactly the kind of thing that the convicted murderer in the Pittsburgh synagogue shooting was exposed to. Shameful and dangerous that a US government agency is referencing such a false, hate filled screed. This should be taken down immediately. @fetterman.senate.gov @deluzio.house.gov

I believe one of the new mRNA vaccines was expected to treat colon cancer, and another had the potential to keep pancreatic cancer from recurring. That’s what they’re taking away.

I’ve harped on the media for very poor reporting of the ways jobs numbers are produced, but I also want to highlight good examples such as @bencasselman.bsky.social at New York Times and this piece by NBC News. Good, informative economic journalism is possible. www.nbcnews.com/business/eco...

Statement from the largest economics association about the BLS firing As context: AEA approximately never makes such public statements This is a big deal
