The macroeconomic scientist must have a cognitional theory. The real is not the ‘already out there now’; objectivity is not merely animal extroversion; verification is not merely ‘taking a look‘. What science verifies is to be found in general affirmations. Continue reading
We have recited some aspects of the dynamic economic process:
- (Dummy) money “must be constant in exchange value.”
- Prices alone do not explain the economic process. Prices must be interpreted in the light of those significant variables which actually explain the economic process.
- The economic process of production and exchange always is the current, purely-dynamic process
- The economic process is an organic whole
- The process has an exigence for a normative pure cycle of expansion.
- Equilibrium requires the keeping of pace and balance among interdependent flows of products and money
- Scarcity is the normal cause of inflation
- Maladjustment of incomes is the maladaptive cause of inflation
- Just as the surplus phase of the expansion is anti-egalitarian in tendency, postulating an increasing rate of saving, … so the basic phase of the expansion is egalitarian in tendency; it postulates a continuously decreasing rate of saving [CWL 15, 139]
- The central adjustment to the respective phases of the process may be formulated as adjustment of I”/(I’ + I”), the ratio of surplus income to total income
- Interpreters of prices must distinguish between real and relative price increases monetary and absolute changes in prices We have recited some aspects of the dynamic economic process: (Continue reading)
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)
Free open markets work better than central bureaucracies.
The excellence of the exchange solution becomes even more evident when contrasted with the defects of a bureaucratic solution. The bureaucrat … (gives the people) what he thinks is good for them, and he gives it in the measure he finds possible or convenient; nor can he do other wise, for the brains of a bureaucrat are not equal to the task of thinking of everything; only the brains of all men together can even approximate to that. … when a limited liability company has served its day, it goes to bankruptcy court; but when bureaucrats take over power, they intend to stay. … when the pressure of terrorism is needed to oil the wheels of enterprise, then the immediate effect is either an explosion or else servile degeneracy. … the exchange solution is a dynamic equilibrium resting on the equilibria of markets. … every product of the exchange economy must mate through exchange with some other product, and the ratio in which the two mate is the exchange value. The generality of this equilibrium makes it indifferent to endless complexity and endless change; for it stands on a level above all particular products and all particular modes of production. While these multiply and vary indefinitely, the general equilibrium of the exchange process continues to answer with precision the complex question, Who, among millions of persons, does what, among millions of tasks, in return for which, among millions of rewards? Nor is the dynamic solution unaccompanied by a continuous stimulus to better efforts and more delicate ingenuity. For the uniformity of prices means that the least efficient of those actually producing will at least subsist, while every step above the minimum efficiency yields a proportionately greater return.

Philip McShane had a strong background in mathematics and theoretical physics; thus he was able to understand the scientific significance of Bernard Lonergan’s macroeconomic field theory in an Einsteinian context.
First we display, in brief, key excerpts, many of which contain analogies from physics and chemistry, relevant to the science of Functional Macroeconomic Dynamics; then we show the same excerpts more fully within lengthier quotes. Continue reading
To help the reader gain an appreciation of Lonergan’s achievement of Modern Macroeconomic Field Theory we will, in each section, print leading excerpts, then highlight the key concepts of those excerpts. We will comment on the historically-significant advances in geometry of Euclid and Hilbert, in physics of Newton and Einstein, and in macroeconomics of Lonergan.
- Euclid’s great achievement was his rigorous deduction of geometry.
- Hilbert’s great achievement was his employment of implicit definition to reorder Euclid’s geometry.
- Newton’s two great achievements were unifying the isolated insights of Galileo and Kepler into a unified system of mechanics and his invention of the calculus.
- One of the great achievements of Einstein was the invention of the field theories of Special Relativity, General Relativity, and Gravitation.
- One of Lonergan’s several great achievements was his systematization of macroeconomic phenomena in his Modern Macroeconomic Field Theory. He combined the technique of implicit definition introduced by Hilbert and the concept of a field theory developed by Faraday and Einstein; and he developed an explanatory macroeconomics, which is general, invariant, and relevant in any instance.

The heart of the normative theoretical framework that can actually explain business and trade cycles is what (Lonergan) calls the ‘Pure Cycle’ (§10, §24, 114). This cycle generalizes into clearly articulated relationships the ideal phases characteristic of major economic transformations as they depart from a stationary phase and move through phases first of surplus expansion and then of basic expansion, only to return to a new stationary phase. … (CWL 15, Editors’ Introduction, lxiii) (Continue reading)
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).
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
There is required a shift of focus by academics from the concrete secondary determinations of prices and quantities in a non-systematic manifold to the immanent, abstract, primary relativities which may be applied to these secondary determinations to reach particular laws.
Paraphrasing [McShane, 1980, 127]: Taking into account past and (expected) future values does not constitute the creative key transition to Functional Macroeconomic Dynamics. Continue reading
