Are generative AI tools threatening freelance jobs? Not quite, says a new study. Instead of mass job losses, demand is shifting:

📉 Fewer jobs in repetitive writing & translation
📈 Strong growth in machine learning & AI-related roles
Experience matters too.

Thank you for the suggestion. We have 'unknown' categories in more recent Seshat version, so doable.
maria-drc.bsky.social
Thank you very much for the suggestion. Very creative! Should be doable with NER, though caveat might be token limits/budget. I'll notify the team. Dan Hoyer is also interested in several AI/ML applications.

These are fair criticisms but miss the crucial point...

Academics publish in expensive OA journals because top journals and citation count remain the dominant factors in determining whether you get hired and whether you get promoted...

This will not change unless the incentive structure changes

Why do academics not publish their work on an academic shared space that universities collectively use?

Why is it required to have a layer of publishers that simply do not publish anymore.

In the days of expensive paper printing it made sense. In the digital era it makes no sense at all.

There's an interesting new study by @ernestaigner.bsky.social @drodrik.bsky.social @jacobgreenspon.bsky.social on regional publication trends in economics - share of "authors based in low income countries remains low" disproportionate to those countries population shares vs. world ⤵️
