Here’s why fewer employed economists is bad for Joe Biden

If a reporter ever gets in touch, you should suggest the headline “You can’t vaccinate against Elon: DOGE nearly as bad as COVID for universities”

I want to teach an Economics of Immigration course (no I don't), just once, so I can have this image as my opening slide.
Incredible satire or the least self-aware image of all time?

Extremely biased from my own background, but I've always thought doing a Critical Theory survey course should be required for economics. Narrowing in on seeing the world only in economic terms too soon can be limiting

Good history helps us avoid nostalgia. The great article “Economic History and the Historians” (2020) by Anne McCants reminds me why nostalgia can get us in trouble. Two of her examples are very relevant to today: vaccinations and the popular narrative of some economic “good old days.”
Getting vaccinated is unpleasant. Dying of measles is worse. In the decade before the 1963 vaccine for measles emerged, an average of 475 Americans died from measles every year, most of them children. This (absolute) number had dropped to a low of 1 in 1981, despite a steadily increasing population that might have hypothetically contributed additional cases. Sadly, the number of measles cases in the United States has been steadily climbing upward again because we seem not to remember the ravages of the disease so much as the inconvenience of the shot—even without taking into account the absurd rejection of the solid scientific evidence in favor of vaccinations. Many people still have an elderly relative who survived a bout of severe childhood illness; not one of us has an elderly relative who did not. The blurring of the historical evidence for and against vaccination that arises from strangely incongruous historical narratives allows a seemingly inconsequential but nonetheless deadly nostalgia to run rampant. Another example of dangerous reverence for the past concerns the flurry of popular enthusiasm lately (at least if the pundits of the 2016 American election are to be believed) for the “good old days” of the 1950s when a family could live securely on just one income (in these nostalgic accounts, that one income is usually a man’s). Lest we forget, these are the same good old days of poor air quality and measles. Maybe trivial in comparison but certainly indicative of the scope of the cognitive problem that nostalgia presents, the average size of a new home built in America in 1950 was 983 sq. ft.; by 2010, the average size had risen to 2,392 sq. ft. Given that families were larger on average in the 1950s than they were in 2010, per capita space allocation had risen even faster than total area. Although we might not need that much personal space, many of us have become used to it. Older furniture now looks tiny compared to what is now on offer in showrooms, whereas older television sets were behemoths with miniscule screens showing programs in glorious black and white.

It feels like every day we're the customer in Akerlof's Lemons, and we're watching the average price go lower. and lower. and lower.

Honestly, I wonder if the rise of the mini-series or seasonally adaptation of book series is just the kind of sidestep around this.

Anyway, back to my LOTR Extended Editions

Why would some business interests prefer for Congress to fly blind in tax policymaking? 🤔

Very good take from @howardgleckman.bsky.social @taxpolicycenter.bsky.social:

Listen when you unilaterally decide to ignore a statute you can’t just go halfway. In for a penny, in for a (who knows where it came from?) pound

You should have Nate on the podcast! I’m sure he’d love to do it. And he’s really good at talking about models (both theoretical and econometric)

In my first post, I explain why we should be careful about citing the $312 billion statistic on the size of Chinese money laundering

It’s back to the “L” line now!

Now describe to your audience “the Mainline”

It’s such a weird space! A lot of it recently is in traditionally low risk firms, but gigantic issuance size with really weird terms/exposure.

And why it keeps getting pushed to retail is baffling, why does retail need exposure to this. And the products popping up to gain that exposure…

The Fed is not good at talking to citizens. Its communications culture is aimed at markets, which means it knows how to give coded, cautious hints that leave room for negotiation. That means there's little will and no experience with strong, affirmative signals in response to wanton norm-burning.

Hah, fair enough. A decade is more than enough time spent. Maybe it helps that Black Dog was the best coffee shop in town at the time? (I’m told things have improved since. I hope)
