The Keynes-Hayek rap video is finally here and it's brilliant. The lyrics cover Keynesian economics and Austrian business cycle theory very well but what I liked best were the many ways in which the visuals, the story and the music subtly and sometimes not so subtly (!) parallel the economics–e.g. note what happens to Keynes after the big party!
It's clear that a lot of thought went into integrating the music, the story and the lyrics in order to make the most of this medium and I give my colleague Russ Roberts and John Papola much props.
