It is the function and purpose of the macro-economist to decipher from aggregate numbers the correct metrics by which they can craft policy to equililibrate…the macro-economy. That even the best of them who have iconoclastically de-bunked DSGE think that they have actually come up with something all that significant in RE-discovering what Douglas originally discovered over 90+ years ago, namely that the economy is actually in a radical state of disequilibrium….is really kind of pitiful and would be funny from a scholarly point of view if the pain, suffering and enslavement of the individual to that underlying systemic instability didn’t so far exceed the silliness of missing/not comprehending it. In other words what they haven’t done….is craft macro-economic policies that will actually resolve that disequilibrium and even enable positive price deflation within a profit making economy. That’s what Douglas did. It was sheer economic transformational insight and wisdom.
