We invite graduate students and early-career researchers who are interested in studying the economics of AI to apply – ***regardless of prior experience working on the topic*** #econsky

We welcome researchers interested in any aspect of the economics of AI, broadly defined. We are particularly interested in research that:
1. is focused on the economics of *transformative* AI
2. is forward-looking
3. is expected to be of durable importance, and
4. moves fast :)

What you’ll get:
– $10k, and you should ask for more if you have a reason
– a conference in SF in a few months with senior economists and AI developers
– opportunity to access Stripe data and/or work with its customers
– a community of fellow nerds

Introducing the Stripe Economics of AI Fellowship:

The economics of AI remains surprisingly understudied. The fellowship aims to help fill that gap, by supporting grad students and early-career researchers with $, data, a conference, and community –

Anyway Tom’s post is very poetic and deeply resonant personally with my own experience pushing Greek letters around, check it out

Trump tariff proposal reportedly reduced to only cover “critical” security imports — Leopold Aschenbrenner has an old, interesting alternative to these tariffs:

Minimal *quotas* for critical goods — idea being Weitzman/Hayek meets geoeconomics:

Soo no discussion of this Tyler post on “The future of the scientist in a world with advanced AI” because it’s too depressing or?

need an RCT to know whether tweeting about an AEA session actually increases attendance:

7. Collect credible estimates of VSL over time -- how has it evolved over time & with GDP growth?

If I follow -- this 2015 @chrisblattman.bsky.social post (featuring @johnjhorton.bsky.social and others) may be discussing exactly this

Accuse me of naive optimism but it doesn't seem to me our choices are only "10% inflation" or "10% unemployment"... let's just do even better next time?

2. Relatedly (and again tentatively): an update against *downward* nominal wage rigidity -- the idea that nominal wages are asymmetrically rigid downward, but not upward
- seems like wages have been rigid upward too
- would be very curious if someone digs (or has dug) into this

Tentative takeaways for macro theory, based on Zach's empirics showing wage growth has been uniformly weak in the recent episode:
1. Basic sticky wage theory looks extremely good?
November 18, 2024 at 4:29 PM
Zach then puts it all together showing how different methodological choices take you
...from +1.5% growth -- this is the number in the charts you see floating around twitter --
...to -1.7% growth

Check out the full post, the 14 footnotes are more interesting than most tweets

Point 3: if you look at median growth in *total income* rather than in *wages* -- i.e., including taxes/transfers: there was a collapse in the Biden presidency

(in large part due to stimulus timing; and an increase in household formation)
November 12, 2024 at 9:33 PM
Point 2 (this one is still crazy/slightly hilarious to me):
- *the change in median wages* is not what matters
- it is *the median change in wages* that does
And, other than the Great Recession, this growth was the lowest it's been in 30 years (!)
November 12, 2024 at 9:33 PM
Point 1: In no part of the income distribution did wages grow faster while Biden was president than they did 2012-2020 (!), in the raw data and especially with a composition adjustment

This from @zmazlish.bsky.social is THE analysis of wages/income under Biden-Powell

TLDR: growth has been... historically weak (this is not normative -- just the numbers)

"average weighted tariff >6% by Q4 2024"...

context: currently 2.5%
