Causa finita: the end of I=S/IS-LM

Comment on Lars Syll on ‘Hicks’ misrepresentation of Keynes — the Wicksellian connection’

Blog-Reference and Blog-Reference on Sep 11 and Blog-Reference on Sep 23 adapted to context 

Keynes formulated the formal core of the General Theory as follows: “Income = value of output = consumption + investment. Saving = income − consumption. Therefore saving = investment.” (1973, p. 63)

This elementary syllogism is conceptually defective because Keynes never came to grips with profit (Tómasson et al., 2010, p. 12). As a result (i) all I=S models and the Keynesian multiplier are false (2011), (ii) the Wicksellian interest rate mechanism is false, (iii) the theory of interest is false, (iv) Hicks’s/Krugman’s/Farmer's IS-LM models are false (2014).

The periodic rewarming of the I=S/IS-LM debate of the 1930s is only good for one thing: to demonstrate the abysmal scientific incompetence of both orthodox and heterodox economists. For details see cross-references Refutation of I=S.
