I am not going to defend Mr. Trump’s economic policy announcements nor his choice of advisers. I have argued above that economists have no mandate to dabble in politics because (i) this violates the principle of separation of politics and science, and (ii), economists have no true economic theory and are therefore a serious hazard to economic policy in general.
The short proof goes as follows. The most elementary configuration of the economy consists of the household and the business sector which in turn consists initially of one giant fully integrated firm and is defined by these three OBJECTIVE axioms:
(A1) Yw=WL wage income Yw is equal to wage rate W times working hours L,
(A2) O=RL output O is equal to productivity R times working hours L,
(A3) C=PX consumption expenditure C is equal to price P times quantity bought/sold X.
The investment good sector comes in with the second step. So, what we have with (A1) to (A3) is the pure production-consumption economy as the most elementary economic configuration.
From these elementary, objective, transparent, and intuitively convincing premises follow the basic version of the Employment Law which is shown on Wikimedia AXEC62:
The factor cost ratio ρF as defined above embodies the price mechanism which works very differently from what is usually assumed. As a matter of fact, overall employment (in the world economy or a closed national economy) INCREASES if the average wage rate W INCREASES relative to average price P and productivity R and vice versa.
This follows in an unbroken chain of transparent logical steps from (A1)/(A3). The Employment Law consists alone of measurable variables and is readily testable.
However, what professional economists assert since time immemorial is this: “We economists have all learned, and many of us teach, that the remedy for excess supply in any market is a reduction in price. If this is prevented by combinations in restraint of trade or by government regulations, then those impediments to competition should be removed. Applied to economy-wide unemployment, this doctrine places the blame on trade unions and governments, not on any failure of competitive markets.” (Tobin, 1997)
This is the worst piece of standard economic analysis and prescription of all times.
The advice to lower wages is based on a logically defective theory and leads to ever more unemployment/depression/deflation according to the axiomatically correct Employment Law.
Professional economists with impeccable credentials have caused enormous social devastations since the Great Depression. At the very least, they should now stop giving the impression that they have any valid scientific ideas to save their fellow citizens from mass unemployment and stagnation.
Mr. Trump and his non-professional aides may be economically dangerous for the USA. But, how much damage they will presumably do will not be worse than what professional economists have already done.
The idea that professional economists can save the world is patently absurd. It is just the opposite.
