Agree!

And I'd add that most vacancy taxes are structured to only penalize long-term vacancies, where properties are vacant more than 6 months or the year, and purposely held off the market.

See, e.g., Vancouver's expansive Empty Homes Tax exemptions. vancouver.ca/home-propert...
Evidence and exemptions: Will your home be taxed?
Determine if your property will be subject to the Empty Homes Tax (Vacancy Tax).

I thought a bit through @missingmiddleca.bsky.social's inclusion of vacancy taxes in the category of harmful policies with regards to overall supply and decided to blog it.

With thanks to @jensvb.bsky.social and @lausterna.bsky.social wonderful work on Unoccupied Canada.
The point of vacancy taxes is to increase vacancy rates

This is not even tangential to the matter at hand but whenever I read something to the effect of not shooting the messenger, I am reminded of @daraobriain.bsky.social's virtuoso bit about people saying controversial things.

US building codes requiring two stairs in multifamily buildings: not only worse living environments, but also more dangerous in fires! What a combination.
Consultants contracted by Minnesota found that an eight-story single-stair building with 6,000 sq. ft. per floor (building 4) has dramatically lower fire risk than a same-height code-compliant two-stair building with a larger floor plate (building 1) www.dli.mn.gov/sites/defaul...

Also like the negative effects of rent control on construction are not particularly large if the program is designed properly! The revulsion from economists feels mostly aesthetic to me

This is an argument I have made for a while - if you want to allow more new housing development, you'll face a lot less opposition if you protect existing tenants with rent regulation. Nice to have some more evidence to back that up.
Um, ok...

This paper forthcoming at the JOP provides evidence that rent control in Germany actually made tenants MASSIVELY *less* NIMBY.

This result was in the opposite direction of the authors' pre-registered expectations.

And the effect sizes are, truly, massive.

Something something 3% vacancy rate
“If you trace back many important decisions of the last few decades, you will regularly come up against the uncomfortable sensation that the unacknowledged legislators are … junior civil servants who put placeholder numbers in spreadsheets, which were later adopted as fundamental constraints.”

While prepping for a presentation in Toronto a few weeks ago, I picked up that one of our graphs hadn't been updated with 2025 numbers. We just made the change. Here's how historically affordable Québec is doing.

There was a twist on the Mencken quote (Puritanism: the haunting fear that someone, somewhere, may be happy) that stuck with me.

We are essentially governing ourselves out of the haunting fear that someone, somewhere, may be getting something that they don’t deserve.
A lot of reactionary and conservative sentiment is dependant on the article of faith that there can’t ever be enough of anything for everyone. It’s attachment to scarcity as the material requisite to « sensible » or « common sense » allocation of resources.

Breathing easier -- study finds that congestion pricing worked in NY resulting in significant reduction in air pollution.
"The study found that, from January through June 2025, average daily maximum PM2.5 concentrations in Manhattan’s CRZ declined by 3.05 micrograms per cubic meter – a reduction of 22% compared to a projected average of 13.8 micrograms per cubic meter had congestion pricing not been implemented."

There is no way to find a lasting solution to the housing crisis when prices are set by the highest bidder. Every serious plan requires more homes than there are people to dilute the price-setting power of competing bids.

In light of another sports association losing their minds/nerve/soul over trans people, here is a reminder: the people who care about trans people in sports don’t know anything about sports, and less than nothing about women’s sports.
Now you have to know: I train 4 hours a week and I do 8 to 10 tournaments every year and believe you me I suck at badminton. There are levels to this which you can’t know about unless you’re invested.

I don't know if I read it from Roth before it stuck with me, but the description of recent reactionary movements as a force trying to make the world *smaller* feels like the most correct and insightful. Lines up with yesterday's post about keeping "normal" small.

Like a lot of Jason's stuff, this is insightful. My take, as someone who scanned as "not normal" for some time, is that we'd have better conversations about identity and alterity if we framed "normal" as a standard that everyone is expected to meet, and not just the average of all existing things.
This is actually quite brilliant, up to and including the final sentence 🔥
