Elements of The Analysis

Our aim is to prescind from human psychology that, in the first place, we may define the objective situation with which man has to deal, and, in the second place, define the psychological attitude that has to be adopted if man is to deal successfully with economic problems.  Thus something of a Copernican revolution is attempted: instead of taking man as he is or as he may be thought to be and from that deducing what economic phenomena are going to be, we take the exchange process in its greatest generality and attempt to deduce the human adaptations necessary for survival. [CWL 21,42- 43]

Taking into account past and (expected) future values does not constitute the creative key transition to dynamics.Those familiar with elementary statics and dynamics will appreciate the shift in thinking involved in passing from equilibrium analysis…to an analysis where attention is focused on second-order differential equations, on d2θ/dt2, d2x/dt2, d2y/dt2, on a range of related forces, central, friction, whatever….. What is significant is the Leibnitz-Newtonian shift of context. [McShane 1980, 127]

A distinction has been drawn between description and explanation.  Description deals with things as related to us.  Explanation deals with the same things as related among themselves.  …  description supplies, as it were, the tweezers by which we hold things while explanations are being discovered or verified, applied or revised. … [CWL 3, 291/316]

again, as to the notion of cause, Newton conceived of his forces as efficient causes, and the modern mechanics drops the notion of force; it gets along perfectly well without it.  It thinks in terms of a field theory, the set of relationships between n objects.  The field theory is a set of intelligible relations linking what is implicitly defined by the relations themselves; it is a set of relational formsThe form of any element is known through its relations to all other elements.  What is a mass?  A mass is anything that satisfies the fundamental equations that regard masses.  Consequently, when you add a new fundamental equation about mass, as Einstein did when he equated mass with energy, you get a new idea of mass.  Field theory is a matter of the immanent intelligibility of the object.

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.

Explanation By Gross Domestic Functional Flows To Supplement Description By Gross Domestic Product

A distinction has been drawn between description and explanation.  Description deals with things as related to us.  Explanation deals with the same things as related among themselves.  The two are not totally independent, for they deal with the same things and, as we have seen, description supplies, as it were, the tweezers by which we hold things while explanations are being discovered or verified, applied or revised. … [CWL 3, 291/316]

The analysis of the overall dynamic functioning, which we call in nominal terms the economic process, must seek the explanation of the process.   It must seek the objective immanent intelligibility among the interdependent, dynamic “functionings” which altogether constitute the process.  The functionings are rates of so much or so many every so often, and, thus, they are velocities.  And the scientific analysis must be in terms of abstract, implicitly-defined, explanatory conjugates rather than in terms of the descriptive accountants’ unities of merely legal or proprietary entities called “firms.” (Continue reading)

A Superior and Far Less Expensive Macroeconomics Textbook

A very expensive macroeconomics textbook, having 700-1000 pages, would contain a lot of interesting history, a lot of fuzzy psychology, unscientific analysis, and uncertain conclusions.  A reader would not gain a clear theory and complete explanation of the dynamics of the real economic process.  However, is there not a superior 228-page, far less expensive  textbook right in our hands?  How about this?  Reword the subtitle of CWL 15 from An Essay in Circulation Analysis to A Textbook of Circulation Analysis, and let the professor instruct the serious student to read the book three times, then report back to discuss the following:

  • the canons of empirical method
  • a scientific, dynamic  heuristic
  • the technique of implicit definition; explanatory terms defined by the functional relations in which they stand with one another
  • velocitous functional unities of scientific and explanatory significance replacing the BEA’s descriptive, commonsense, accountants’ unities
  • the structure of the lagged, rectilinear productive process
  • money as a dummy invented by man
  • the perspective of a hierarchical series of monetary circuits
  • how a monetary circulation meets the rectilinear production-and-vending process
  • the primary relativities and concomitance in the Diagram of Rates of Flow
  • dynamic equilibrium replacing static Walrasian general equilibrium
  • the velocity of money in terms of magnitudes and frequencies
  • prices are not a given and not requiring explanation; rather prices are in need of explanation
  • interpretation of prices, quantities, interest rates in the light of significant explanatory variables
  • the pure cycle and its constituent phases in the expansion of the objective economic process
  • the abstract primary relativities and concrete secondary determinations in the expansion of the economic process
  • the statistical residue and why prediction is impossible in the general case; predicting weather vs. predicting planetary motion
  • the significance of investment’s monetary correlate
  • the ineptitude of manipulating interest rates
  • the explanation of government and foreign-trade imbalances by the dynamics of superposed circuits
  • the distinction between efficient cause and formal cause
  • distinguishing between self-healing and the effect of interventions
  • the intelligibility and explanatory power of the basic price-spread ratio
  • Figures 14-1, 24-7, and 27-1 in CWL 15

The student would learn much that is radically different, explanatory, and very useful; and he/she would gain a perspective or framework by which to evaluate and criticize the flawed premises and tenets of conventional textbooks and traditional theories.


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.

Two economic mechanisms. Two components of concrete relations. Two simultaneous roles for human participants

Part I. Two economic mechanisms. Two components of concrete relations. Two simultaneous roles for human participants

It is the viewpoint of the present inquiry that, besides the pricing system, there exists another economic mechanism, that relative to this system man is not an internal factor but an external agent, and that the present economic problems are peculiarly baffling because man as external agent has not the systematic guidance he needs to operate successfully the machine he controls. [CWL 21, 109]

What the analysis reveals is a mechanism distinct though not separable from the price mechanism which spontaneously coordinates a vast and ever shifting manifold of otherwise independent choices from demand and of decisions from supply. It is distinct from the price mechanism, for it determines the channels within which the price mechanism works.  It is not separable from the price mechanism, for a channel is irrelevant when nothing flows through it. [CWL15, 17] [Continue reading).

A Note on Disagreeing with Einstein and the Determinists, on Avoiding a Vicious Circle, and on the Need for Precise Analytical Distinctions

Economic process – like other world processes – has an immanent intelligibility consisting of primary relativities which can be applied to the coincidental secondary determinations which occur throughout time in a non-systematic manifold. Economic process is constituted  by schemes of recurrence under the dominance of abstract principles and laws; nevertheless, the actual concrete workings of the economic schemes of recurrence are shot through and throughout time with indeterminancy.  So, it is a fact that prediction is impossible in the general case, since the concrete patterns of events occurring throughout time are a non-systematic aggregate. Thus, the point-to-line and higher correspondences are based upon the indeterminacy of the relation between current surplus products and the ultimate later basic products that eventually exit the dynamic process and enter into the standard of living.

An event in an economic scheme of recurrence has a diverging series of conditions. Continue reading

The IS-LM, AD-AS, and Phillips Curve Models

In this section, we are contrasting familiar textbook models of macrostatic equilibrium, with Lonergan’s explanatory theory of macrodynamic equilibrium.  We are contrasting a macrostatic toolkit with a purely relational field theory of macroeconomic dynamics. Lonergan discovered  a theory which is more fundamental than the traditional wisdom based upon human psychology and purported endogenous reactions to external forces.  His Functional Macroeconomic Dynamics is a set of relationships between n objects, a set of intelligible relations linking what is implicitly defined by the relations themselves, a set of relational forms wherein the form of any element is known through its relations to all other elements.  His field theory is a single explanatory unity; it is purely relational, completely general, and universally applicable to every configuration in any instance. (Continue reading)
