# Edifice of Formulae

## Edifice of Formulae of the Ideal Pure Cycle For Review and Self-Test of Foundational and Superstructural Relations

(Upper-case letters represent flows of the form “so much or so many every so often”)

One formula is worth a ton of prose.

Our purpose in this section is to remove the reader from the verbiage and allow him to concentrate solely on the relationships in the equations which explain the concrete economic process.[1]  It is best if one understands the concise and precise mathematical forms, which are isomorphic[2] with the patterns of the dynamic process.  One’s understanding should be comprised of purely relational functionings.

Rebecca Goldstein noted that Kurt Gödel preferred to communicate in a technical manner so as to avoid pointless and combative conversations:

Mathematical verbosity, as opposed to verbosity of any other sort, could not have better suited the personal eccentricities of Kurt Gödel, a man who had so much to say on the nature of mathematical truth and knowledge and certainty, but wanted to be able to say it using only the rigorous methodology of mathematics.  With a proof in hand, he would not have to involve himself in the sorts of combative human conversations he regarded with distaste, maybe even with horror. Goldstein, Rebecca, Incompleteness (New York, NY: W.W. Norton & Company, 2005), 135

Equations are devoid of hot air and excess verbosity.  In and of themselves, they are neither psychological nor political.  They are purely relational forms.  Equations offer us the advantages of a.) stating concisely and precisely at an adequate level of abstraction the implicit primary relationships among implicitly-defined explanatory terms, b.) suggesting that values for the secondary constants and variables be as determinate and precise as probabilities allow, and c) comprising a coherent, unified, and complete  theory comprised of classical and statistical laws.  A few equations of adequate generality may encapsulate tens, or even hundreds, of pages of verbiage.

Below are key “classical” equations upon which to focus for eventual mastery.  In any conversations with those locked into the IS-LM, AD/AS, and Phillips Curve mentality, it may be wise to take a lesson from Gödel and simply ask which of Lonergan’s generalizing and explanatory formulae they find to be mistaken.

We have arranged this presentation of the classical laws of functional macroeconomic dynamics as an orderly progressing “upward” from basic terms and equations, which form a systematic core, to culminating differential and difference equations which explain the Why and How of the overall economic functioning.  The view is arranged “from the bottom up” in 3 columns of Production, Monetary, and Unitary Equations. So, the reader should start at the bottom of the list, where there are a Goal, a note re Ideal velocities, a key symbol k, and foundational formulas; then the reader can work his/her way “back up” to the top, where there is a culminating formula for Gross Domestic Functional Flows.

In this progression “up” through the formulae, the reader should have at hand the following diagrams from CWL 15.

• Figure 14-1, Diagram of Rates of Flow
• Figure 24-4, Growth of Surplus Production (Q”) over the Pure Cycle
• Figure 24-6, Growth of Basic Production (Q’) over a Pure Cycle
• Figure 24-7, Rate of Change of dQ’/Q’ and dQ”/Q” over a pure cycle
• Figure 27-1 Rate of Change of v, w, and f during a pure cycle, Ideal Maximum f.

The reader can then “see” the equations “embedded” in these Figures.  And one should thereby “see” the concrete creative-destructive process being properly “realized”.  One would thus be using this as a self-test of one’s understanding of functional macroeconomic dynamics.[3]

the functional correlation of pure surplus investment expenditures-receipts with expansionary investment outlays
using quantity indices, selling-price indices, and profit-price indices (vectors).
Prices and quantities are defined implicitly by the interrelations within and between their functional flows rather than exogenously as a given.

Implicit definition of “costs” and “profits” [11]
There is a sense in which one may speak of the fraction of basic outlay
that moves to basic income as the “costs” of basic production.  …
For the greater the fraction that basic income is of total income (or total outlay),
the less the remainder which constitutes the aggregate possibility of profit.

[1] Among these Topics in Functional Macroeconomics are four treatments which concentrate on the explanatory mathematical formulae, but present them in different orderings.  The four treatments are entitled:

1. Cluster of Key Relations: Seeing Production, Exchange, and Finance All in a Single View
2. Key Equations Module
3. Buildup of Formulae
4. The Formulation of Functional Interdependencies

[3] As a separate exercise at another time, the reader should study a)

• Figure 29-1 Diagram of Superposed /circuits
• Figure 31-1 Diagram of Government Spending and Taxes,

so that he can understand and appreciate the possible superpositions of mitigative or distortive circulations of money passing non-normatively through the Redistributive Function, and b) the horizontal and vertical flowings from and to the Redistributive Function, so that he can understand proper and improper adjustments of the money supply so as to either enable the flows of an ordered process or torture the flows of a disordered process.

[13] We need not here identify the constants and variables of the formula, since our only purpose is to demonstrate that the interest rate is a.) intrinsic  to the process, and b.) interrelated to all the constants and variables of the process.

The history of the development of money points to a preponderant role of increasing turnover magnitude in circuit accelerations.  CWL 15, 68
