I discovered the surprising story of what really happened in 2008 (not enough housing) and accidentally became a housing policy guy. https://kevinerdmann.substack.com/ https://www.amazon.com/stores/Kevin-Erdmann/author/B099P7SN1G

WOW. 19 people, all who were imprisoned and mistreated in a foreign prison at the direct command of the United States, are brave enough to say β€œWe are innocent, and we will endure more time imprisoned to prove that.”

I can only admire the enormous courage such a move takes.

It’s hilarious how scary the completed new home inventory must look to those who don’t understand the scale of the housing shortage.

Anyway, take note because it’s about to decline pretty sharply. It will be quite a bit below the current level by year’s end.

I don't know if they are all based on the same category of fallacious reasoning, but I think they must be sort of related.

I feel like the Venn Diagram of people who say
"Production moves where wages are lower because they are a competitive advantage."

"It is wrong to let foreign workers come in to the country to pick produce just because Americans insist on being paid more."
&
"AI will take all the jobs."
is a circle.

Under current conditions, there will inevitably be a building boom, and it will be associated with moderating home prices and declining homeownership rates, and I’m afraid those trends will break enough brains to lead to policy choices that kill it.

I wouldn’t be surprised if effective ADHD medications are a significant reason for declining crime rates over the past couple of decades.
Those medicines change lives, deeply.

New Privately-Owned Housing Units Completed: Units in Buildings with 5 Units or More/Population*1000 New Privately-Owned Housing Units Completed: Units in Buildings with 5 Units or More/Population*1000

Our little apartment boomlet wasn’t nothing. But it’s kind of pitiful. And if it was enabled by Covid distancing rules that made local feces throwing sessions less effective, it is a sign of how massive a post-zoning building boom would be.

As the guy who wrote the book on zoning abolition, I'd like to go on record as saying: if you can use zoning to stop the concentration camps, fucking go for it.

Just think what a badass country you would be if a country next door was 10 times your size and one of their most celebrated unifying national stories is that every 40 years or so they manage to win a sporting match against you.

US price/rent ratios will very likely end up back below 17 again. The question is will it be the 1950-1970 path (a building boom) or the 2007-2012 path (demand shock)?

btw, the 2008 demand shock never ended so it can’t be repeated.

The response to Trump’s escalation of illegal tariffs in defiance of the US Constitution and SCOTUS, in addition to a global boycott of US products, services and tourism, should be the expelling of US diplomats from all attacked nations, and the initiation of global sanctions, until he is removed.

it would make way more sense to have road portion of development cost charges levied on the purchase of cars than it does to have it on the purchase of houses.

Why the "Lesser Included Action" Argument for IEEPA Tariffs Fails - Marginal REVOLUTION The Supreme Court yesterday struck down Trump’s IEEPA tariffs, holding that the statute’s authorization to β€œregulate… importation” doesn’t include the power to impose tariffs. The majority’s strongest...

Great firefighter analogy.

You know, Republicans are allowed to just say "that's enough of this" and act accordingly. I won't cast any shade or wag fingers as long as we get back to democracy.

In case the labelling isn't clear, it is quarterly mortgage origination volume for each range of credit scores, compared to origination volume for scores above 759.

Today's post is for subscribers only, but I thought some of you might be interested in this chart, which I think shows the ridiculous scale of the mortgage crackdown in 2008 very well.

Absolutely bonkers.

Ah. Makes sense. I stand corrected. And, of course monopoly profits are famously unrelated to the enforcement of barriers to competition. It’s the standard Ricardian result. I hadnβ€˜t considered that.

Afaict, they are doing two things. (1) Assuming families are homoeconomicus and that when millions of low-income families are regionally displaced it’s no big whoop. Just choices about utility. And (2) when avg income rises as a result, mistaking that for demand from families with high incomes.

A lot of people are complaining about federal cutbacks in healthcare spending. But how many of those complainers have even bothered to snort cocaine off a toilet seat? Hardly any of them. They just want to do whatever they want and they expect the rest of us to support them.

If high amenity or well located lots in the market had sold for, say, $200,000 per lot while unimproved poorly located lots had sold for $5,000 per lot, in the pre-shortage days, I would expect the high amenity lot to sell for, say, $350,000 while the marginal lot sells for $155,000.
