1/OK, so. Let's talk about Left-NIMBYism.

We all know about Right-NIMBYs, rabidly protecting their white-flight suburbs from Those People. And there are plenty of liberal NIMBYs too.

But NIMBYs of the Left are also a force to be reckoned

2/Left-NIMBYs have developed a canon of interlocking, mutually reinforcing beliefs about housing and urbanism.

These beliefs are mostly false, but they form a powerful "canon" that quickly ossifies into a hardened worldview.

It looks something like this:
3/Fortunately, Nathan J. Robinson of Current Affairs has written an article that perfectly encapsulates the Left-NIMBY worldview (and quotes me in it!).

So this is a teachable moment.

https://t.co/nvFJryQZGi
4/Robinson selectively quotes a Bloomberg article of mine (https://t.co/iamRrW6oei).

Look at the part he quoted, vs. what I actually wrote!

Pretty different, eh? 😉
5/In fact, as I wrote in the article that Robinson failed to read more than one line of, it's theoretically possible that Left-NIMBYs COULD be right that allowing market-rate housing drives up local rents.

I take that possibility very seriously, as do YIMBYs.
6/But as always in economics, we need to look at the EVIDENCE, not just theory!

And although there isn't a mountain of evidence on market-rate housing yet, some evidence is starting to pile up.

And it doesn't look great for the Left-NIMBY theory.
7/For example, here's a 2016 paper by Xiaodi Li about what happens to nearby rents when you build market-rate housing.

8/And here's a brand-new paper by Kate Pennington about what happens to rents and to gentrification when you build market-rate housing in San Francisco:

9/And here's a 2019 paper by Brian Asquith, Evan Mast, and David Reed, about what happens to rents and to gentrification when you build market-rate housing:

https://t.co/6YPHc38NDF
10/There are others (https://t.co/Hp3ecU9Ly0, https://t.co/AjipSyRSOy), but the general result here is starting to become clear.

Market-rate housing lowers nearby rents while drawing high-income people away from low-income neighborhoods.
11/In fact, reality looks very much like my "Yuppie Fishtank Theory" (which is really just a segmented markets model).

It's an explanation of why YIMBYism doesn't need Econ 101 or Supply-and-Demand:

https://t.co/8o6V0L4Wbv
12/But Robinson gets things even more wrong when he claims that YIMBYs are Randian shills who hate public housing and demand that market-rate housing be the only solution.

Here's what he writes:
13/Robinson singles out three YIMBY organizations for his accusations:
California YIMBY
YIMBY Action
Open New York

Let's see what each one has to say about public housing, shall we?

Here's Brian Hanlon, co-founder of California YIMBY.

https://t.co/hU4hWQh1Px
14/Here's Laura Foote, executive director of YIMBY Action:

https://t.co/M52O8R67St
15/Here's Ben Carlos Thypin, founder of Open New York:

https://t.co/OxII8YxxKh
16/Robinson simply failed (or refused) to do his homework. His characterization of these YIMBYs is utterly wrong. In reality, they're just a bunch of lefties who want to build ALL types of housing instead of insisting on just one.
17/In fact, I think the conflict between YIMBYs and Left-NIMBYs is not fundamentally about evidence, or about public housing.

It's about preservationism vs. growth and change. Left-NIMBYs want to stand athwart urban history, yelling Stop.
18/Whereas YIMBYs recognizes that cities will always grow and change, and we can't preserve them in amber. Instead, we have to shape their growth into something equitable and inclusive.
19/Left-NIMBYism is not confined to the West Coast; you see it popping up in cities across the nation. It's wrongheaded, but it's something we're going to have to deal with as we fight to make American cities livable for everyone.

Yes, we have been more divided than we are now. Within living memory.


Labor disputes used to kill hundreds of people!

In 1932 Douglas MacArthur called in tanks on protesting veterans, injuring over a thousand people!

In 1967 there were 159 race riots in cities across

In 1921, rioters used airplanes to bomb black businesses in Tulsa, Oklahoma! Hundreds were killed in the riot!
This thread demonstrates that a lot of academic writing that *looks* like utter nonsense is merely scholars dressing up a useful but mundane point with a ton of unnecessary jargon.


My theory is that the jargon creates an artificial barrier to entry. https://t.co/MqLyyppdHl

If one must spend years marinating one's brain in jargon to be perceived as an expert on a topic, it protects the status and earning power of people who study relatively easy topics.

In econ, a similar thing is accomplished by what recent Nobel prize winner Paul Romer calls "mathiness": https://t.co/DBCRRc8Mir

But mathiness and jargon are not quite the same...

Jargon usually doesn't force you to change the substance of your central point.

Mathiness often does. By forcing you to write your model in a way that's mathematically tractable (easy to work with), mathiness often impoverishes your understanding of how the world really works.

has written about this problem:
Today's @bopinion post is about how poor countries started catching up to rich ones.

It looks like decolonization just took a few decades to start

Basic econ theory says poor countries should grow faster than rich ones.

But for much of the Industrial Revolution, the opposite happened.
https://t.co/JjjVtWzz5c

Why? Probably because the first countries to discover industrial technologies used them to conquer the others!

But then colonial empires went away. And yet still, for the next 30 years or so, poor countries fell further behind rich ones.
https://t.co/hilDvv0IQV

Why??

Possible reasons:
1. Bad institutions (dictators, communism, autarkic trade regimes)
2. Civil wars
3. Lack of education

But then, starting in the 80s (for China) and the 90s (for India and Indonesia), some of the biggest poor countries got their acts together and started to catch up!


Global inequality began to fall.
