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.
