As always, I enjoyed the hour.  Hope you do as well.

I suspect it was this post that led to the invitation.  I really do believe Fisher’s 1933 Econometrica article offers a more complete model of the entire business cycle process than anything in Keynes’s General Theory
It took Hicks, Alvin Hansen, and other interpreters to translate the General Theory into a complete model, one where you could intuitively understand who was making which decisions, how it all added up to a complete economy where everyone was being at least modestly rational.  
Fisher, by contrast, implicitly tells you: “Just take your old, familiar classical model, perfectly flexible wages and prices, but add in just this one thing: Debt contracts that are tough to get out of.”  Then he shows the the consequences of that one tweak.  They are not small.
