Econ has some ML gems. One of my favorite's is Sandroni's sweeping result that no empirical test can distinguish an informed from an uninformed forecaster. I teach it in my ML class: www.youtube.com/watch?v=7OAI... But it is presented as negative, when it is in fact a sweeping positive result.

How can managers identify GenAI use cases?

I was struggling to find a good framework to teach my MBA students how to find GenAI use cases in their orgs - so I made my own!

I called it the "BEAST" framework for finding LLM use cases - see details below.
