A Contrast: Understanding Pricing in Macrostatic DSGE and in Macrodynamic FMD

.I.  Introduction: Contrasting Diagrams and What They Represent

We contrast an assumption and description with an explanation and interpretation.  We contrast the Dynamic Stochastic General Equilibrium (DSGE) assumption and description of pricing as exogenously given and acceptable as a lead item in analysis of economic problems with Functional Macroeconomic Dynamics’ (FMD’s) explanation and interpretation of pricing in the light of the significant functional pretio-quantital flows, which explain the dynamic economic process.

Modern Monetary Theory Fails to Qualify as Scientific Macroeconomics

Scientific macroeconomics, if it is to be genuinely scientific, must not be contaminated by human psychology.  Gustav Kirchhoff’s laws of the electric circuit do not incorporate the psychology of the human who operates the levers or switches.  So, Lonergan, the scientist, strove to discover the purely relational, purely functional laws of the circuits of the objective economic process.  Unfortunately, many proponents of Modern Monetary Theory exhibit sentiments and inclinations favoring a totalitarian bureaucracy for the management of fiscal and monetary affairs. Their purported science contains some valid assertions, but is not a coherent set of objective laws to which participants must adapt, regardless of sentiment; rather MMT is an admixture of several ideological and psychopolitical sentiments transformed into a contaminated set of mandates for the management of fiscal and monetary affairs.  The tenets of MMT fail to constitute a fully explanatory theory of macroeconomic dynamics.

Why Economists Don’t Flock to Functional Macroeconomic Dynamics

Economists don’t have the methodological and conceptual toolkit needed for appreciation of FMD’s scientific and historical significance.

  • They don’t know what they don’t know.
    • They’re not methodologists and don’t know what constitutes good theory.
    • They never read CWL 3, pages 3-172 and 490-97 and, thus, they never studied the canons of empirical method, especially the Canon of Parsimony and the Canon of Complete Explanation; they have no idea of the deficiencies of their method.
  • Thus, they lack a purely scientific and explanatory heuristic.
    • They do not adequately distinguish description vs. explanation.
    • They do not know the type of answer they’re seeking, i.e. their known unknown.
    • They do not put questions in the right order to discover basic terms of scientific significance.
    • They are mired in muddy premises and disorienting assumptions.
    • They are unable to employ a scientific, dynamic heuristic adequate for analysis of a current, purely dynamic process.
    • They don’t understand what constitutes the normative system’s requirement for  concomitance, continuity, and equilibrium of flows.
  • They lack a background in theoretical physics. They don’t understand the principles and abstract laws of hydrodynamics, electric circuits, or field theory.  Nor do they understand adequately the idea of continuity and the conditions of equilibrium in macroeconomic dynamics.  They are unaware of analogies from physics applicable on the basis of isomorphism to the phenomena of Functional Macroeconomic Dynamics.

Textbook Flaws and Deficiencies

The popular textbooks of Macroeconomics – by N Gregory Mankiw, Paul Krugman and Robin Wells, Olivier Blanchard, Andrew B. Abel and Ben S. Bernanke, William J. Baumol and Alan S. Blinder – suffer in common from several flaws.  Our subheadings immediately below and the pointers thereafter point out flaws and deficiencies in textbooks commonly used in higher education. Though the treatments in this section are not exhaustive, they are sufficiently provocative; they should stimulate careful scrutiny of, and skepticism regarding, many traditional and conventional tenets.  Finally, though the treatments in this section are relatively brief and often primarily referential, there is a lot of ground to cover; so, we will underline and publish as time allows.
