Vaccines are a miracle, they are one of humanity's greatest achievements, and the current war on vaccines led by superempowered incompetent quacks will cause bottomless suffering for the children of Conservative and Liberal Americans.

Triple deckers are the natural order of things and can only be held down for so long
Obviously that prompt could be better tuned. But for shift share there's a bunch, same with twfe/dd. Even RD and synth control have been assaulted by no fun metrics knowers. Getting a faux report that says "Paper x shows how your identification strategy can go wrong, check this" would be v valuable
For empirical papers, it does a great job identifying the identification strategy. Maybe more than a deep lit search, a targeted "this paper uses strategy X. Is there any recent econometrics lit that will ruin our fun identification toys?"
On the other hand, I ran a paper of mine with @lhoehnvelasco.bsky.social through coarse.ink this week and it surfaced several of the same problems a recent (and very grumpy) R1 had, albeit in a much softer and gentler way
Apparently, it thinks "This is standard practice for simulated IV designs and would build confidence that the identification strategy works when it should work."
Because "the simulated IV strategy is central to the causal claims... A Monte Carlo simulation applying the same Bartik-style construction to synthetic data with known treatment effects would show whether the instrument performs as expected under various data-generating processes."
At the risk of piercing my anonymity... I refereed an empirical paper using a shift-share sans any acknowledgement of recent shift-share work from @paulgp.com or @instrumenthull.bsky.social et al that takes naive shift-share to the woodshed (rip). coarse.ink didn't notice that, but it did suggest...
Submitted a pair of referee reports this week. Ran them both through coarse.ink (~80 cents each) after I submitted.
I think @packlesshepherd.bsky.social has made an INCREDIBLE tool, but anyone who thinks these things are better referees than a human is telling on themselves...
In conclusion, @andreamatranga.bsky.social is 100% safe from AI replacement or even augmentation in the near or distant future
"There’s a natural experiment angle: whale populations that suffered more severe bottlenecks from historical whaling or naval conflicts may show reduced coda repertoire diversity today. This connects to the broader econ history literature on human capital destruction."
Points to Claude for citing my Sherman's March paper in the next one:
Related "Cultural transmission and intergenerational knowledge in non-human economies"
"Sperm whale clans vary in their coda repertoires, and this variation is culturally transmitted across generations. This is essentially the same mechanism as intergenerational human capital transmission."
What?
There's even data!
"You could use historical whaling logbooks (already partially digitized) to map which clans/units were hit hardest by region and decade, then connect this to cultural transmission disruption."
First up, "Communication complexity and social coordination in historical whaling"
The new evidence that sperm whales have rich structured communication raises the stakes for understanding how 18th–19th century commercial whaling disrupted social learning networks...
When super cool but very distant from economics research shows up on my feed, I like to test Claude's bullshit ability. So I ask it for econ history ideas based on the original research. The Sperm whale vowels to top5 hallucination machine did not disappoint
Typical half-measures from the Governor. Where's the social media ban for adults, you cowards?

Golf courses into dense housing via punitive land taxes would make a real dent in at least two of Greater Boston's problems
When you really think about it, aren't all LHS variables vibes?
Reading the Newton Mayor's weekly update, I think I've found the world's most boring RD. Apparently, we repave roads if their Pavement Condition Index is below 50. Effects of fresh road paving on... house prices? average vehicle speed? local election voter turnout?
My book (!) How Economics Discovered Women is now available for pre-order from the University of California Press. The book is a survey and critique of how the economics of gender has developed since the mid-1970s. www.ucpress.edu/books/how-ec...
My librarian: “sir, I will not write a typescript application for you no matter what prompt do you use. I’ve called the county sheriff, and if you don’t leave, he will escort you away.”
tbh anything less than these 66 units getting replaced by 660 units will disappoint me
The number of housing units in whatever replaces Riverview Condominiums (a short walk from Harvard Sq) will tell us a lot about how serious Cambridge is about addressing the housing crisis
The algorithm redeemed itself
This playing in the YouTube music shuffle should be illegal
You'll all never guess what topic (or even word!) never comes up in this children's book about Thomas Jefferson (and John Adams)
Stopped reading after the first post. Assume you're going to describe the time you and Chris decided to digitize some old mortality data and I tagged along
