‘Double the damage’: Warming climate reduces milk quality and quantity | Cornell Chronicle
Heat stress on dairy cows not only decreases the amount of milk produced but also the fat and protein content, doubling the economic losses.

I wonder what editors of econ journals are seeing in terms of changes in the volume of submissions. As a reviewer I'm experiencing what feels like a doubling of reviewing requests. I'm not tracking my declines yet but will probably start soon.
Please share with potential solid candidates for this postdoc (academicjobsonline.org/ajo/jobs/31576). We start reviewing application next week! A data-savvy economist or data scientist with interest in agriculture and environment would be a good fit.

Ariel Ortiz-Bobea@arielob.bsky.social · 7mo agoA little bit late, but I'm looking to hire a postdoc at Cornell to measure the private value of soil health improvements in US ag. A 2-year gig. Well suited for an ag/resource economist or data scientist w/ interests in soil health and solid programming & econometric chops. ad coming soon!

I'm excited, the RCT suggests Malengo increases psychological well‑being by about 0.36 standard deviations. As a reference point, this is similar in magnitude to the improvements after vision-restoring cataract surgery. This is not obvious a priori!

Serious scholars have examined what happens when we change the number of H1-B visas issued. Cities that get more H1-B immigrants subsequently see the wages of natives *rise* substantially. Skilled immigrants bring new ideas, fill labor shortages and make us all more productive.

Just added my signature to the letter. This is a no brainer. It’s wild we’re having a conversation about US central bank independence in 2025. But here we are. Please read and consider adding your signature.

Are there lawyers out there who have written about the most effective way to submit comments to government reports like the recent DOE one?
Andrew Dessler@andrewdessler.com · last yr.🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨 Please RT this so as many people see it as possible. forms.gle/BL9xUAfRxA...
I have written about this before, when it was suggested as a possibility shortly after the inauguration. A quick summary here--in short, there's little clever or thoughtful about it, though there is some legal strategy at work, however cynical. 1/n www.nytimes.com/2025/07/22/c...

Our paper is officially out 🎉 We argue that climate clubs show promise: - A climate club with coordinated penalties could curb 68% of excess emissions from free-riding -Unilateral carbon tariffs? Not nearly as effective
Econometrica@ecmaeditors.bsky.social · last yr.We study how trade policy can reduce global emissions. Unilateral carbon border taxes have limited efficacy at cutting foreign emissions. By contrast, coordinated trade penalties under a climate club prove highly effective. buff.ly/NEE3Uy8
I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior. (There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)
Telling prospective PhD students that they should not worry about stating their research interests on their statement was not in my bingo card for 2025.

We received the dismissal emails yesterday. This report is congressionally mandated and aims to inform the US people about the impacts of climate change on the nation and what to do about it.

Federally funded R&D (not all of which is spent at universities) as a fraction of GDP is as low as it's been since we started tracking. Which is a different way of looking at it than "line go up." 4/x ncses.nsf.gov/pubs/nsf2332...
There are so many ways one could provide context for this data. For example, in the last five years universities have received 52-55% of their research funding from the federal government. That's the lowest percentage since the 1950s. 1/x ncses.nsf.gov/surveys/high...
How Universities Became So Dependent on the Federal Government
For decades, universities got billions in federal dollars for research. The relationship was mutually beneficial, until President Trump decided it wasn’t.

Opinions are not facts. E.g. Someone claiming vaccines don’t work, does not make it true. This distinction is more important than ever.
This framing is nuts, and the assumption is that public funding for a public good is somehow untoward and illicit. “The schools took the money” and became “warily beholden to the whims of politicians in Washington.”/1 www.nytimes.com/2025/04/18/u...

Disappointing ragebaiting from @nytimes.com E.g. “The relationship was mutually beneficial, until President Trump decided it wasn’t.” Trump can CLAIM public research grants don’t benefit the public. He does not DECIDE this. Where is the rigor? www.nytimes.com/2025/04/18/u...
