Stylized facts and vacuous interpretations

Comment on ‘The IMF on Investment since 2008’


Obviously your post lacks an underlying coherent theory. To make a long argument (2015) short, the correct employment equation for the investment economy is given here.

The equation says that employment L increases with
• investment expenditures I,
• an increasing expenditure ratio rhoE (=C/Y),
• an increasing factor cost ratio rhoF (=W/PR),
under the condition of product market clearing if price P and productivity R in the consumption and investment good industry as well as distributed profit Yd remain unaltered in the period under consideration; it decreases in the opposite case. The testable equation explains unemployment.

The income distribution affects the expenditure ratio rhoE. The dependency of the average expenditure ratio from wage income and distributed profit and their different expenditure ratios is given with eq. (30) in (2014).

The employment equation above accounts coherently for both the effects of investment expenditures and distributional changes (and a bit more).

It is important to note that distribution theory crucially depends on profit theory. It is very probable that your profit theory is false (again see 2014) and therefore your interpretation of the IMF data is pointless.
