Here's the AER editor trying to convince you how benign the use of AI is in the editorial process - "just a detailed technical proofreader." I've seen what AI does to students' behavior. Editors are no different. Once let it in the door, it will be asked to do all manner of stuff. e.g. desk rejects.

Who could have imagined legislating a bunch of costs onto landlords would have the effect of land lords leaving the sector and rents going up.

Peer review is genuinely not a fraud detection mechanism and shouldn't be taken to be. It's not really a knock against a peer review system for failing to pick up when data is faked. The system is already over worked if we did data forensics at scale as a standard part of review it grinds to a halt.

Being an academic really is one of the best jobs imaginable. No idea why so many academics complain about it so much.

Maybe this is spitting hairs but “social media attack” sounds somewhat petty or like bullying behavior, whereas what happened here is that people documented that there were serious errors in a paper and got stonewalled when they tried to go through the “normal” academic mechanisms for addressing it

3/ Examining the methods and code revealed a coding error caused by trying to include fixed effects perfectly collinear with the treatment. Correcting this error showed no effect of the reform on rape. We sent this partial replication to the author and journal.

Democrats are so bad with messaging on this. These tariffs are unpopular and they are going to be extraordinarily unpopular.

It's strange how Tim is keen to highlight this yet ignores the fact that one of his own co-authors is responsible for the tariffs in the first place!

Apparently Yanis Varoufakis thinks that Trump’s tariffs are based on a solid masterplan, which means that I have to update neither about the plan nor about Varoufakis.

In one fell swoop, Stephan Miran, Pierre Yared, and Kim Ruhl have destroyed not only their own reputations, but also those of anyone that has ever worked with them on any paper or other piece of work. I would be ashamed to have my name on the same project as theirs.

OBR forecasts are increasingly contentious; not only do they reflect Government policy, they increasingly shape it. The 2022 mini-budget fallout is the starkest example of the OBR’s impact. A 🧵on the pressure this puts on the OBR to get things right 👇

The OBR has been criticised rather a lot recently, and while some of that criticism is valid, much of it is misplaced. @pedroserodio.com and I have written for @ukdayone.bsky.social to set out where the OBR might be able to improve and suggest a way forward to implement improvements.

This is a good policy! Universities should not get to skim off absurdly high proportions of grants to cover "overheads". Even 10% would be too high a proportion.

but if activism becomes the goal and people in universities are seen as having very different values and agendas than most people, then support erodes and universities can lose their legitimacy. To some extent, I think this is what is happening.
