Economics is a failed science and this is the current state in Hume’s apt metaphor: “... when the road ends at a coal-pit, he [the traveler] doesn’t need much judgment to know that he has gone wrong, and perhaps to find out what has led him astray.”
So, let us find out what has led economics astray.
Nick Rowe says: “National Income Accounting identities then tell us: C+S=Y=C+I, and therefore S=I”
Just for the record (there is no hope for Nick Rowe to ever understand it):
- Because of a conceptual error/mistake/blunder, these equations are false since Keynes.#1
- National accounting replicates the conceptual error/mistake/blunder and is false, too.#2
- All After-Keynesians, except Allais, were too stupid to identify the foundational error/mistake/blunder of macro.#3
