Austin’s Surge of New Housing Construction Drove Down Rents

After decades of explosive growth, Austin, Texas, in the 2010s was a victim of its own success. Lured by high-tech jobs and the city’s hip reputation, too many people were competing for too few homes. From 2010 to 2019, rents in Austin increased nearly 93%—more than in any other major American city. And home sale prices increased 82%, more than in any other metro area in Texas.

Its wild how the solution to housing costs is really just:

Build more housing. Keep law and order.

No it doesn’t need to be “affordable”. Yes rent control is a terrible idea.

Just build more housing.

Note: that the US already has plenty of housing and housing costs basically go up in areas of low crime relative to economic opportunity. If you build housing, but allow crime to rise, you have wasted everybody’s time.

New construction has already decelerated in Austin due to falling prices, which compresses already-near-zero margin on real estate development.

So yes, it really is "just build more housing." The problem is: why would you build more housing as prices fall?

I'm confused by this objection, if you draw a stereotypical supply and demand curve, you can see how prices settle to an equilibrium point. Of course reality has more complications, but I think your objection is 95% answered by a supply and demand curve. You keep building houses when it is profitable. You stop when it is not. This naturally keeps everything in balance.

If a minority has most of the wealth then the equilibrium supply may include a lot of supply of second homes, very large homes on large plots for the rich, properties sold at a premium based on how much they can extract from renters, and even investment properties occupied by nobody whilst still having insufficient small basic homes and dense housing.

Capital that could be invested in better serving the bottom half has to compete not only with the use of those resources to further enrich the rich but other investment opportunities.

There is more than enough land for everyone, and rich people aren't really competing for the kind of housing that poor people are competing for, e.g. smaller plots with smaller homes. The demand of the rich does not eliminate demand of the poor, so the market produces different kinds of housing for different clientele.

Think about it this way: assume you supply all the housing to all the rich people. Then there still remains untapped demand of others that can be fulfilled by further production of homes for those specific people.

This story fails when land becomes restricted, which is exactly what zoning laws cause. Zoning is a big harm to the poor.

But zoning is required to maintain order. Nobody wants anybody to live in favelas.

As with everything the regulator needs to strike a balance to make the market work.

Given the choice between being homeless and living in favelas, millions in Brazil have chosen to live in favelas.

The reality of zoning laws in Western countries is to provide a target for regulatory capture by the NIMBY crowd. With the result that we're systemically underbuilding housing, then wonder why we wound up with homelessness.

Favelas are a local optimum which systemically is very difficult to get out of and is a sign that the regulator is powerless. It's a great example of a market failure.
