Good morning, chilly Amherst! Looking forward to my talk today on #AI saturation & the future of work, and to seeing dear colleagues & meeting new ones! #AcademicLife

Result 4 (simulation). Here we simulate adding more AI, during and after automation. (1) Wage effects of adding more AI saturate. (2) Higher substitutability between physical and intelligence can lead to wage declines during automation but allows for unbounded wage growth post-automation.

Result 3 (simulation):when intelligence and physical are more substitutable, automation of intelligence has a larger positive effect on output.

Result 1: as automation of intelligence by #AI progresses, output increases and there’s an increase in the share of workers in the physical sector \beta (i.e., in person work, including e.g. cooking, teaching and surgery).

Model: Output is produced with intelligence and physical sectors (CES), each powered by humans and capital (AI is the capital in the intelligence sector). Labor optimally reallocates between physical and intelligence to maximize wages.

We've made an interactive tool you can play with to see how wages would evolve with automation & with adding exponentially more #AI, depending on parameters of your choice. Have fun (but maybe read the paper first 😈)! intelligencesaturation.org

Are the 2020s the disaster decade? David Brooks thinks every historical time has its own disaster, except maybe the 1990s. I grew up in the 1990s, so maybe that’s one more way I’ve been very lucky. What do you think? 1990s yay or nay? 🤔

To read the discussion, see section 3.3.1. We point out that concentration is not always a good proxy for WELFARE, as it might increase welfare when it results from higher productivity. However, concentration is still a measure of market POWER. Thoughts? papers.ssrn.com/sol3/papers....

Here’s guideline 10 in the 2023 merger guidelines: “When a merger involves competing buyers, the Agencies examine whether it may substantially lessen competition for workers, creators, suppliers, or other providers.”

Significant victory for labor #antitrust as Judge Adrienne Nelson issued a preliminary injunction blocking the $24 billion merger of grocery giants Kroger and Albertsons, in a win for the FTC. The judge mentions the inclusion of workers in the 2023 Merger Guidelines, an issue I worked on at DOJ
