None of the things you mention support building more housing.

A few look like they might, but don’t: Increasing taxes on expensive real estate just pushes demand down the chain, reducing supply for all.

If empty houses are actually a problem, fix the root cause. I can think of two reasons a house would go empty: Speculation (betting there will not be enough houses built), or planning departments that prevent the house from being repaired.

Making it easy to build houses solves both those problems.

If you attack landlords, who do you expect to build and maintain rental housing?

The affordable housing requirements are similar nonsense: Say you have some cash to invest. If you put it into building housing, the government will require you to sell the houses at a loss. Are you really going to build houses, and not invest it in something that can at least break even?

The yimby folks in CA are useful idiots that serve people that want housing prices to stay up. If you don’t believe this, go take an introductory micro and macroeconomics course.

It might surprise people in the U.S. to know that the Abundance agenda is not at all how many other international cities solve affordable housing. Did you know that one in four Parisians live in public housing? Or that in Singapore it’s 80%?

Or did you know the National Bureau of Economic Research just published a study concluding “Supply Constraints Do Not Explain House Price and Quantity Growth Across U.S. Cities”?[1] Directly contradicting the YIMBY narrative that all we need to do is unleash market rate supply.

Simple economics tells us that when you have a boom town with strong demand from white collar professionals migrating in, driving up incomes, they will outbid lower income folks for market rate units ten out of ten times. Per the law of supply and demand, all of that demand needs to be satisfied before market prices even have a chance of declining to affordable levels - and that’s only if the real estate industry decides it is profitable to keep building. Older units get renovated into luxury units as well.

That creates a real scalability problem for cities because you get a labor shortage. That drives up the cost of everything: education, restaurants, and you guessed it, construction itself.

That’s why social housing is such an international standard. Without affordable working class housing, the local economy becomes dysfunctional. And it echoes the debate we had about socialized medicine some years ago, the solution favored by pretty much all other developed countries, but always said to be too expensive or impractical to be done here, the richest country on the planet.

But we’re beginning to see some cracks in the narrative. And it clarifies why these right wing movements find the Abundance agenda so appealing.

Social housing is not one of the solutions the yimby movement in the US promotes. It also works because it doesn’t matter if the government or the private sector builds the houses.

Anyway, that paper concludes there is no difference in housing supply elasticity across the US (which is questionable, to put it politely) so demand elasticity doesn’t explain price differences. So, they conclude that, if you don’t build any houses at all, then demand will set prices.

That says nothing about what will happen if you do build houses, and also doesn’t contradict the basic economic finding that, if you have a glut of supply, prices go down. (Because no outbidding can occur — the losing bid still gets a house.)

> Social housing is not one of the solutions the yimby movement in the US promotes

This is not correct at least for the largest organization, California YIMBY. CA YIMBY has endorsed every social housing reform that has emerged at the state level, for example AB 309, AB 2053, etc.

What idealist socialist critics mean when they say "YIMBY doesn't support social housing" is actually "YIMBY refuses to outlaw market housing".
