Let me flag up this paper that serves as a good example of how or where the AIPNET can potentially be playing an important role going forward around climate action. Let me first summarize the paper, highlight consistency with EU approach before going into broader issues...

Earlier this year, the Presidentβs budget proposed a 40% cut to the budget of the NIH. This motivated us to ask: what if the NIH had been 40% smaller?

It looks like he didn't share it on Bluesky, so I will. @afinetheorem.bsky.social has written an excellent review article covering 7 recent books on the economics of AI that serves as an excellent overview of this topic. Highly recommended!

Common Ownership and Employee Earnings *
JosΓ© Azar Xin Dai Yue Qiu Aaron Sojourner
September 15, 2025
Abstract
Using administrative data in the manufacturing sector from the U.S. Census Bureau, this paper provides the first evidence on the effect of common ownership on
employee earnings. Using firmsβ additions to the S&P 500 index as a shock to their
local competitorsβ common ownership, we find that, after a same-industry competitor enters the S&P 500 index, the average employee earnings of S&P 500 incumbents
in the same local labor market decrease. Additionally, these firmsβ employment increases. These findings are inconsistent with the canonical oligopsony models but our generalized model of oligopsony incorporating a recruitment intensity margin can rationalize them
Common Ownership & Employee Earnings
updated & improved
Consider a pair of companies that sell into the same product market. If pair shares common owners, the owners have incentive for pair to soften competition.
Same with local labor market competition

π¨NEW RESULTS (w/ Slattery & Nober)
- When gov't engineers retire, highway projects cost more: the engineers pay for themselves 6 times over
- Improving govβt engineer quality from the 25th to 75th percentile reduces costs by 14%, equal to 3x avg. engineer pay

We use the lens of a firm's typical lifecycle to ask how competition in the relevant input and output markets shapes investment incentives and constraints at each stage.
We think this allows us to make sense of sometimes conflicting results, and identify remaining evidence gaps.
