Steve Keen whose brilliant de-bunking of DSGE has recently re-discovered the importance of that discipline in following money flows, it’s just that focusing primarily on theoretical and mathematical abstraction he hasn’t looked at the economic/productive process itself and hence hasn’t recognized the point in that process where the convention could be applied for Ptolemaic to Copernican complexity exploding effect.

Are you pleased….or still caught up in epicycles as explanations?
