LLM on Macro: "One camp - call it the "IS-LM plus common sense" school - argues that for 90% of policy questions, the old framework with some mental adjustments for expectations and inflation gives you the right answer. People like Blanchard, Krugman operate roughly in this mode"

Could be improved, but Economics is ranked 1st in terms of "precisely reproduced". (0% "precisely reproduced" in Education, really?🧐)

[Practical payoff] The bc-MC-PEA lets you trade off: * exploring more states (M) * integrating shocks more accurately (N) Optimal values for (M*, N*) are derived in the paper. Easy to implement. 5/n
