Here's a fun way to show how not true this is: of the 150 densest cities in California and Texas (min 50K people), 137 of them are in California
Californians pretend they live in the city and Texans pretend they live in the country, the suburbs where people in both states actually live are largely identical
new follow-up to the "supply constraints dont explain house price growth" paper that's been bopping around for a few years. in this version, they do explain housing price and quantity growth! haven't read so can't vouch. @michaelwiebe.bsky.social have you gone through this one?
real estate professionals often have "does a fish know whether it's in water?" syndrome. they know their environment well; theyre much less helpful on thinking through large changes this is why, while it's always good to take with industry insiders, it's also good to have studies and academics.
what happens is people say "if rents fall then developers stop building" which is a statement about a fixed supply curve. This is not, of course, YIMBYism, which is about a *shift* in the supply curve such that more stuff pencils *at a given rent*. dont reason from price changes exhibit 9
obligatory friends don't let friends use Numbeo. Here's what's happening: 1. most of numbeo's "quality of life" index is prices. it has each of purchasing power, cost of living, and price:home ratios 2. the graphic says it drops these. what's left is healthcare, pollution, commutes, and climate
Sacramento is, by these metrics, the best value and some of the highest quality of life anywhere in the west. California incomes and sunshine with Portland’s prices and Denver’s access to nature is I guess a ranking-friendly combo?
in any case there actually is a good attempt to do this sort of cost of living vs incomes at scale. turns out the midwest is actually pretty good for non-college educated workers because the prices are better than the relative lack of amenities. www.rebecca-diamond.com/files/geogra...

i think these net worth breakdowns are kind of dumb tbh. there's two questions here for the under 35 group: 1. why did wealth skyrocket from 2019-2022? (not shown by WSJ) 2. why did wealth decline from 2022-2025 turns out it's a mix of changes in homeownership, used car prices, and house prices
New Fed estimates of wealth by age are out. Under-35 wealth dropped 23% over these three years www.wsj.com/economy/affl...

Here's another version: Because of the glory of the home mortgage disclosure act, we can see the income of homebuyers with mortgages. Within the same county/neighborhood/neighborhood and adjusting for unit characteristics, condo buyers are poorer than single family home buyers. it's a starter home!
the thing with luxury condos is that they're mostly a myth. 1. within the same county, condos sell for 35% less than single family homes 2. within the same neighborhood, they sell for 43% less 3. within the same neighborhood and adjusting for some quality characteristics, they sell for 21% less
a bunch of states are toying with the idea of charging companies fees based on the number of employees they have on medicaid. including washington, which wants to do a 7k / employee tax. seems like the response would be "dont hire them" www.healthaffairs.org/content/fore...
what's the full policy slate on this? tax the phone calls, tax the texts, tax the job applications, tax the parking spots, tax the car size, tax the swimming pools in the summer, tax the roads, tax the swipes on dating apps. any i miss?
the entry level job market could be dramatically improved by requiring a small deposit for job applications to deter AI slop but any company or government who implemented this would immediately be incinerated by the fury of a trillion suns
@mark-carney.bsky.social be the change. be the first politician to say "in equilibrium". explain to people that, if youre someone sending out sixty legit applications per month you are exactly who will benefit from a tax on job applications.
I think a fair critique of the CPI’s representativeness across households types is that there’s a lot of heterogeneity *within CPI sub component*. It’s pretty easy to make a low income basket with more weight on used cars and less on new. Harder to account for price of used Teslas vs carollas
reviewing ALICE, one of the many, many "alternative cost of living indices". a few thoughts: 1. the index is a lil goofy. clothing is not considered an essential, for instance. 2. no quality adjustment anywhere. not necessarily wrong but does matter 3. CPI is way more transparent methodology wise

Paper seems cool but those event studies look weird. Employment outcomes for the high exposure groups jump up right around 2021, so the effect seems very sensitive to the reference period. Eg, another interpretation is this is a plot of tech hiring in 2021 and slowdown post interest rate hikes
The most AI-exposed new college grads have initial employment declines of 5pp and earnings declines of 13%, partially driven by shifts to lower-paying sectors.
not for nothing but i think people are dunking on this too hard. the underlying econ is all done by people who are considered very respected and some of the foremost experts on this kind of stuff. whether it ends up being correct, idk, but i can assure people they've thought about your objections
New from us: Anthropic just published scenarios for AI’s possible economic impacts, which range from minimal, to explosive GDP growth of 15% by 2030 as knowledge-worker unemployment hits 18%. I sat down with their co-founder Jack Clark to pick his brains on how they’re thinking about all of this.
none of this is to say that their views are *consensus*. i dont think they are, and you can find lots of dissenting economists. for instance, ben moll is generally pretty skeptical of explosive growth. benjaminmoll.com/wp-content/u...
but like people can read the model. the authors are not doing anything that would be considered super outlandish and if they dont want to read the model, they should at least know that a bunch of pretty established economists have read it www-cdn.anthropic.com/files/4zrzov...
obviously income inequality has grown a lot and this is bad but it seems very weird that NBC is reporting a stock return number that is not adjusted for inflation and comparing it to a wages number that is.
(NBC News) — It is now the least rewarding time to be a worker in the U.S. economy since the government started keeping track. @nbcnews.com www.nbcnews.com/business/eco...
has anyone done a formal-ish decomposition of this? I could see / would be interested in checking a story where: 1. the first drop from q3 2021 -> q3 2023 is mostly income relabelling (look at the composition of the business boom and see if we see evidence of this?) 2. the q3 2024 -> now is AI
BLS this morning, with revised 2Q data: "The labor share, which is the percentage of output that accrues to workers in the form of compensation, was 52.8 percent in the second quarter of 2026, the lowest level in the series, which begins in the first quarter of 1947."
