Steve Keen and Pontus Rendahl did a very rare thing. they had an open debate between an heterodox and a mainstream economist. Worth checking it out. Keen linked to the audio here. Rendahl calls it a debate between Keenonomics and Metrodox Equilibrium (see here), whatever that is. If you ask me Rendahl shows the same confusion that most younger -- by which I mean educated post capital debates, and once the new notion of equilibrium (intertemporal short term equilibrium, without a uniform rate of profit) became dominant -- mainstream economists seem to be stuck with (see my previous post too).
