Economist Alex Imas has been tracking the evidence on AI and productivity changes, and now thinks that the macro-economic data is, rather suddenly, showing the increase in productivity that we have been seeing in our micro research. aleximas.substack.com/p/what-is-th...

“Asking ‘will AI replace the artist’ is the same as asking ‘will the camera replace the artist’”, argues @aleximas.bsky.social in the latest instalment of his excellent series of essays on the societal impact of AI. And the answer is No—quite the contrary: buff.ly/4pJiZ71

New post: "Someday We Will All Be Artists" How will AI impact art? Will artists be replaced? No. Art will change, but art makers will be most "automation proof" jobs out there. In fact, many jobs will take on characteristics that we associate with artists. aleximas.substack.com/p/someday-we...

There is also a disconnect on who benefits most: micro (mostly) finds low-skill/less-experienced workers see higher returns, the (limited) macro evidence is more mixed but leans toward higher wage/higher ed people seeing more of the benefits. 2/n

New post: What is the impact of AI on productivity? I review all of the studies and data that I can find and try to provide a synthesis. A disagreement emerges: micro studies find positive benefits but these benefits are yet to show up in the macro data. aleximas.substack.com/p/what-is-th... 🧵

Does this reflect "discrimination"? We can't test this directly. But we think it's likely that there is systemic discrimination by socioeconomic background in academia (Following the very useful framework by Bohren, @instrumenthull.bsky.social @aleximas.bsky.social (20/22)

GPT-5.2 Pro is good enough to check reproducibility & robustness of academic papers across many fields (given the data, can you get the same results? are the statistics brittle?). I wouldn't trust it to automate decisions, but to flag them. It can't do an independent replication with new data, yet.

These results suggest that social desirability may bias estimates of AI use downwards, depending on the setting. But that tools such as the indirect questioning technique can help.
