Imagine teaching your child the alphabet for 6 years before introducing them to stories and books. That's how we teach math. We teach the basic letters and operations grades K-5 THEN we begin to introduce the basic stories it can tell (algebra). #iteachmath #edchat (1/2)

US hasn't had GDP growth >2.5 since before Obama became deporter in chief in '09. Immigration has been consistently lower since then vs the 80s/90s/early 00s. Avg GDP growth '80-2004 ~3.2%, 2008-now: 2.3%. Dems should be like Reagan/Clinton: open borders & free trade=growth!

Shoutout to people in NC: if you opposed gerrymandering and support reproductive freedom in NC this is a very important campaign: @AllisonJRiggs

Immigrants make up a large share of the homebuilding workforce. Without them, our national housing shortage would be even worse. And…contrary to popular myths about immigrants taking jobs, these immigrants complement rather than substitute for native-born construction workers.

Look at the average GDP growth when immigrant populations were increasing (1981-2004) we averaged 3.2% growth vs flat or decreasing (2009-2020) it was 2.3% growth. If you're "Make America Great Again" and want a strong economy, bring back the immigrants.

Tangential thoughts: if concerns on immigration are rooted in economic terms, would it help change swing voters minds if they looked at immigration/GDP data? Look at immigration under Reagan/Bush/Clinton/Bush vs Obama/Trump. Clear trend that immigration helps GDP growth.

1) I don't think there's that much strategy going on here. 2) I think swing voters will be more influenced by how many people are laughing AT them about this one. 3) I don't have my pulse on any swing voters here in Charlotte/or my sphere so I'm curious how this one plays out.

This is very cool. Highly complementary to this work on schools. https://t.co/DYZ3gfppsv

The idea of the gov't picking "types" of immigrants to allow is basically the same argument that the government should pick which companies survive recessions. Let ppl come legally. Legal immigration means fairer competition, smaller black market and legal opportunities to grow.

@ryanbdrm @mattyglesias Freedom of movement makes it easier to undermine authoritarian regimes and boost global GDP. Let people move from where output is low to where output is high and help expand output there. Often there isn't a GDP penalty if they were unemployed/under employed before moving.

@ryanbdrm @mattyglesias If capital/goods can move (and yes they should be able to because it makes almost everyone's lives better), people should also be able to move as a response to changes in the market. Freeing capital but not people means that the capital/goods can be optimized but labor can't.

I think I'd buy the bull case for Harris a bit more if she hadn't rehired so many of the Biden people.

My former nerd self would never have thought about free/open source building plans as interesting or helpful for the world but this is very cool!

When YIMBY-skeptics complain that developers skew much of their building toward the high end of the market, what they’re often not seeing is that there are a lot of regulations pushing them to do that. Minimum lot sizes are a big one on this, particularly in suburban areas.

Do drivers who get e-bikes drive less? Where cycling networks are ample, the answer is yes. Qi Sun et al. explain. One policy implication: where cycling networks are poor, public funds now subsidizing battery-electric cars would often be better spent on cycling accommodations.

Trump did not revive manufacturing or reduce crime, but he did do this.

An ever-present challenge in political economy.

It's a real mystery why California has a housing crisis

Manolo Betancur says today his small bakery, located in one of Charlotte's most diverse neighborhoods, is just two minutes away from “the center of the war on diversity and minorities.” “If Donald Trump, J.D. Vance wins this November, everything I have built is at risk.”
