This was interesting info, but it seems like all it boils down to is build more homes.
In an interesting turn of events, US and Danish government came up with the same to help with the affordability crisis: longer mortgages!
That has sparked some backlash. But in the US, it seems the discussion is focusing on the wrong stuff.
Well, let’s try to learn from 🇩🇰.

Given my first gen roots, this paper was especially satisfying to research and write, even though the results are a bit disheartening. We use administrative data covering all North Carolina public school students, to document five facts about first generation excellence gaps…. .

DELETED: Trump administration deleted a webpage summarizing evidence that “undocumented immigrants are arrested at less than half the rate of native-born U.S. citizens for violent and drug crimes and a quarter the rate of native-born citizens for property crimes.” 1/2

This feels reminiscent of the opportunity the US had in the early 1900s to pick up the best scientific minds when forced out of Europe. That set the foundation for today’s entrenched technological lead. Will another country finally have its chance to do the same?

I want to know what the conversation at home for JD Vance is like. “Yknow Usha, I just don’t think you should be here. A white American should have been in your spot at Yale Law”
In 2023, four of the seven US-based Nobel laureates were immigrants.
That’s a wonderful thing for Americans. It has nothing to do with saying that Americans aren’t good at stuff.
It means that America is a place where the best Americans and best immigrants work together to do great things.

Here’s a thoughtful and balance thread from @TimoBres.bsky.social about what went wrong and what didn’t go wrong with the apparent fraud in the recent paper about AI and scientific discovery
#econsky What do we know about “Artificial Intelligence, Scientific Discovery, and Product Innovation” and about MIT's investigation of this paper, which apparently led to expulsion of its author? And what should we change in response. /1

Wonder what the response is here. It’s certainly different from LinkedIn or Stackoverflow using their own data because they probably said so in ToS. Is it fair use since it’s producing a new intellectual good that is not explicitly replicating the original product?

There was some discussion about how ChatGPT etc would affect online social media content a while back on the old place. This was the first time I’ve seen the ideas in that discussion materialize in the wild. Social content without a personal scarcity to it is repulsive to users.

Academics might miss the industry implication for this; automating alpha signal discovery with AI is possible. This is a big deal because it means that statistical trading strategies are going to start decaying very quickly. What will remain profitable in quant finance? 1/
Researchers used AI to generate 288 complete academic finance papers predicting stock returns, complete with plausible theoretical frameworks & citations. Each paper looks and reads as legit.
They did this to show how easy it now is to mass produce "credible" research. Academia isn't ready.

I speculated about this on the old site. I think there will both be a reallocation to higher value tasks but also a reduction in the number of grad students overall.

An absolutely based take in response to the polio vaccine discourse.
People with homes are so rarely cold at night that I just don’t think homes are necessary anymore.

Fully agree. Verifying a result is a critical value add to science. We should incentivize this type of work. Currency in this realm is reputation so citations make sense. One risk is that we incentivize repeated replication of popularly cited papers. Norm could be only first replication.
In my opinion, we should cite (well-conducted) replications every time we cite the original finding.
We should cite it even if the original result replicates. It says a lot that an independent team of researchers is able to find the same effect.

South Korean president recently tried to instate martial law. It seems that it is being lifted after a vote by parliament so it should be fine. One thing I found very interesting is that an event that may be an input to the martial law decision by the president is striking doctors. Weird right? 1/

Just saw a really really old resume of mine from back in college when I had no experience, no skills, and no idea of what a resume should look like. It's tough getting started on a career with nothing to advertise as experience or skills. It gives me a new perspective on recruiting.
