Macroeconomics of Impractical Prescriptions

This work addresses gross anomaly of Macroeconomics. Among other follies, so-claimed theories lack the time dimension.
Regarding fiscal multiplier, macroeconomists misapply the cross-case marginal propensity to consume to over-time stability; the former of space dimension, while the latter of time (T for time dimension). The Solow growth model is of the same error.
More generally, the iconic IS-LM model suffers from Dimension Aberration and Reverse Causation. As key to LM, the Cambridge Quantity equation of J.R. Hicks M= k∙I (1937) mismatches dimensions. The stock M (for money at a moment, T0) must be linked to the flow I (for income per period, T-1) with a time variable (T1), not a constant coefficient k. Furthermore, the interest rate is named as the effect in IS-LM, in reverse to the cause in the truer liquidity preference of J.M. Keynes, M= L(r) (1936).
Through the book, post-graduate readers of Macroeconomics, Economics, Finance and Political Economy will get new perspectives on their discipline.
