You present three propositions about output, deficit spending, and the Keynesian multiplier and then sum up: “That is the simple arithmetic of expansionary fiscal policy in a liquidity trap.”
The fact of the matter is that the multiplier arithmetic is flawed since Keynes. Therefore, the rest of your argument falls flat.
To cut the meticulous formal derivation short (2015; 2014; 2012), the most elementary version of the correct Employment Law for the economy as a whole is given under the label of Graphic as AXEC62:
From this equation follows:
(i) An increase in the expenditure ratio ρE leads to higher employment L (the letter ρ stands for ratio). An expenditure ratio ρE>1 indicates credit expansion, a ratio ρE<1 indicates credit contraction/debt repayment of the household sector.
(ii) Increasing investment expenditures I exert a positive influence on employment; a slowdown of growth does the opposite.
(iii) An increase in the factor cost ratio ρF≡W/PR leads to higher employment.
The complete Employment Law is a bit longer and contains, in addition, profit distribution, public deficit spending, and import/export. From employment L, one comes to output O by multiplying both sides by productivity R. The employment/output equations contain but measurable variables and are testable.
Items (i) and (ii) are familiar since Keynes. What is missing in the Keynesian employment multiplier, though, is the ratio ρF as defined in (iii). This variable embodies the price mechanism. It works such that overall employment increases if the average wage rate W increases relative to the average price P and productivity R.
The Employment Law says that an increase in investment expenditure or deficit spending, i.e., ρE>1, increases employment. The multiplier, though, is different from Keynes’s flawed multiplier. The crucial difference consists of ρF.
The correct Employment Law reproduces the familiar Keynesian mechanisms. What is more important: it shows that the price mechanism, i.e., the relationship of wage rate, price, and productivity ρF, can be used to increase employment/output. Thus, there is, to begin with, no need to increase private/public debt or push investment. The crucial point is that the price mechanism does not work as standard economics claims, in other words, standard price theory is provably false.
Hence, the real problem is not at all that 'Ordoliberalismus and Ordovolkismus' do not understand the logic of deficit spending, but that both Keynesians and Walrasians have no idea of how the price mechanism in the monetary economy works.
