Refuting MMT’s Macroeconomics Textbook

Comment on Bill Mitchell on ‘Macroeconomics ― MMT Textbook’*

Blog-Reference and Blog-Reference Mar 14 and Blog-Reference

MMT is, of course, accurate as far as the refutation of Orthodoxy/Neoclassics is concerned. Standard economics is scientifically indefensible. There is no need for further discussions about the current state of economics. This is where we stand today: provably false
• profit theory, for 200+ years,
• microfoundations, for 150+ years,
• macrofoundations, for 80+ years,
• the application of elementary logic and mathematics since the founding fathers.

However, the critique of Orthodoxy has run its course: “… it takes a new theory, and not just the destructive exposure of assumptions or the collection of new facts, to beat an old theory.” (Blaug)

MMT claims to be a new theory that beats Orthodoxy. This is accurate with regard to the shift from microfoundations to macrofoundations. Microfounded approaches are dead already since Walras/Jevons/Menger. The problem is that economists in their incurable scientific incompetence messed up the indispensable Paradigm Shift from microfoundations to macrofoundations.

MMT is NO exception. And the proof is in the new MMT Textbook, more specifically in the premises of MMT. It holds what Keynes observed with regard to Orthodoxy: “For if orthodox economics is at fault, the error is to be found not in the superstructure, which has been erected with great care for logical consistency, but in a lack of clearness and of generality in the premises.”

The premises of MMT Macroeconomics are laid out on pp. 13-16 and pp. 83-86.

“By placing government, as the currency issuer, at the centre of the monetary system, the MMT approach immediately focuses on how a government spends, and how this spending influences … macroeconomic aggregates …” (p. 13)

This is methodologically false. Macroeconomics starts with what Keynes called the ‘monetary theory of production’. The most elementary economy consists of the household sector, the business sector, and the central bank. Government and foreign trade are included at a later stage. For the central bank holds that it “can never run out of its own currency.”

“One of the most basic propositions in macroeconomics that MMT emphasizes is is the notion that at the aggregate level, total spending equals total income and total output.” (p. 14)

Unfortunately, the most basic proposition in macroeconomics is false since Keynes, and MMTers have not realized it until this day.

Here is the short proof that economists in general and MMTers, in particular, get the elementary mathematics that underlies macroeconomics wrong.

(i) The elementary production-consumption economy is given by three macroeconomic axioms: (A1) Yw=WL wage income Yw is equal to wage rate W times working hours. L, (A2) O=RL output O is equal to productivity R times working hours L, (A3) C=PX consumption expenditure C is equal to price P times quantity bought/sold X.

(ii) The focus is here on the nominal/monetary balances. For the time being, real balances are excluded, i.e. X=O.

(iii) The monetary profit of the business sector is defined (in simplyfied notation) as Q≡C−Yw,

(iv) The monetary saving of the household sector is defined as S≡Yw−C.

(v) Ergo Q≡−S.

The balances add up to zero. The counterpart of household sector's saving S is the business sector's loss −Q. The counterpart of household sector dissaving (-S) is business sector profit Q. Both Q and S are measurable with the precision of two decimal places.

For the elementary investment economy holds Q≡I−S.

For the elementary investment economy plus government holds Q≡(I−S)+(G−T). If I and S are taken out of the picture for a moment, one gets Public Deficit = Private Profit.

In sum: (1) profit is NOT income, i.e. a flow, but a balance, i.e. the difference of flows, (2) distributed profit Yd is income and adds up with wage income Yw to total income, (3) total income is NEVER equal to total spending, (4) in the most elementary case, the difference between total spending of the household sector C and total wage income Yw is saving/ dissaving, (5) profit/loss of the business sector is the mirror image of dissaving/saving of the household sector, i.e Q≡−S, (6) saving and investment are causally INDEPENDENT and NEVER equal, (7) all I=S/IS-LM models are false since Keynes/Hicks, (8) Keynesianism, Post-Keynesianism, New Keynesianism and all variants are scientifically worthless, (9) the foundational MMT sectoral balances equation (I−S)+(G−T)+(X−M)=0 is false because it lacks the balance of the business sector Q, (10) because profit is false, the whole of MMT is false, (11) because the theory is false, MMT policy guidance has no sound scientific foundations.#1

MMT theory is provably false. MMT policy serves the Oligarchy. Since Samuelson started the textbook industry in 1948, economists have produced NOT ONE textbook that satisfies scientific standards.#2 For generations, economics students swallow proto-scientific garbage without batting an eyelid. Not very smart, these folks.#3

You ask: “Have you managed to convince anyone that your definition, oops, “axiom,” [sic.] of profits is correct?”

The ‘axiom of profits’ exists only in your confused mind.

The macroeconomic AXIOMS are enumerated above under (i). The profit DEFINITION is given under (iii). There is a difference between axiom and definition.#1

There is also a difference between ‘to refute’ and ‘to convince’. Bill Mitchell and you are REFUTED and whether you are convinced of it is a matter of indifference. Nobody has any ambition to convince methodologically undereducated Flat-Earthers.#2 Refutation is sufficient.

You ask: “So, you have no links to *anyone* who agrees with you? These paradigm shifts are pretty darn slow, eh?”

The point at issue is: “One of the most basic propositions in macroeconomics that MMT emphasizes is is the notion that at the aggregate level, total spending equals total income and total output.” (Mitchell et al., p. 14)

This “most basic proposition” is provably false.#1 Because of this, the whole analytical superstructure is false. Because of this, MMT is proto-scientific garbage. Because of this, MMT policy has NO sound scientific foundations. Because of this, MMT is a political fraud.

The ‘most basic propositions’ are called axioms in methodology: “The attempt is made to collect all the assumptions, which are needed, but no more, to form the apex of the system. They are usually called the ‘axioms’ (or ‘postulates’, or ‘primitive propositions’; …). The axioms are chosen in such a way that all the other statements belonging to the theoretical system can be derived from the axioms by purely logical or mathematical transformations.” (Popper)#2

As Aristotle put it: “When the premises are certain, true, and primary, and the conclusion formally follows from them, this is demonstration, and produces scientific knowledge of a thing.”

This was 2300+ years ago, however, economists in general and you, in particular, still don’t get it. Indeed, pretty darn slow, these economists.

The point at issue is that MMT is proto-scientific garbage and that MMTers are either stupid or corrupt or both. The new MMT Macroeconomics Textbook is the incontrovertible proof.

It holds as a general rule: The time it takes economists to realize that they are refuted on all counts is a simple metric of their scientific incompetence.#3

There is only one question to answer: Which sectoral balances equation is true/false?

(i) (I−S)+(G−T)+(X−M)=0

(ii) (I−S)+(G−T)+(X−M)−(Q−Yd)=0

If you cannot answer this question you are unfit for economics/science. This, of course, holds also for the authors of the new MMT Macroeconomics Textbook.

There is no need for you to wreck your tiny brain with writing “a text that may be labelled a ‘review’”. Here is the final evaluation of William Mitchell, L. Randall Wray, and Martin Watts’s Macroeconomics: proto-scientific garbage.

Wikimedia AXEC128, AXEC129mch The Humpty Dumpty Fallacy

Knowledge only — no opinion

Science does not explain everything, but non-science explains nothing.

Neither orthodox nor heterodox economics satisfies the scientific criteria of material and formal consistency.

Economists cannot explain how the economy works. The Profit Theory is false since Adam Smith. There is much opinion and little knowledge.

Opinion is the realm of political economics, knowledge is the realm of theoretical economics.

Political economics is scientifically worthless.

Theoretical economics is built upon clearly stated premises, i.e., upon a set of axioms.

Orthodoxy got the axiomatic foundations wrong and Heterodoxy has none at all.

Economics is a failed science. Economists are incompetent scientists.

Profit

Neither Classicals, nor Walrasians, nor Marshallians, nor Marxians, nor Keynesians, nor Institutionialists, nor Monetary Economists, nor MMTers, nor Austrians, nor Sraffaians, nor Evolutionists, nor Game theorists, nor EconoPhysicists, nor RBCers, nor New Keynesians, nor New Classicals ever came to grips with profit. Hence, they all fail to capture the essence of the market economy.

Because of this, economists have nothing to offer in the way of a scientifically founded economic policy guidance.

The hybrid science

As a first approximation, one can agree on the general characteristic that the economy is a complex system.

However, with the term system one usually associates a structure with components that are non-human. In order to stress the obvious fact that humans are an essential component of the economic system the market economy should be characterized more precisely as a complex hybrid human/system entity.

The scientific method is straightforwardly applicable to the sys-component but not to the hum-component. While it is clear that the economy always has to be treated as an indivisible whole, for good methodological reasons the analysis has to start with the objective system-component.

In gestalt-psychological terms the economic system is the foreground, individual behavior the background. Common sense wrongly insists that the hum-component must always be in the foreground. This fallacy compares to geo-centrism. The economic system has its own logic which is different from the behavioral logic of humans. The systemic logic is what Adam Smith called the Invisible Hand.

There are systemic laws but no behavioral laws. Systemic laws have the same methodological status as physical laws.

Neither Orthodoxy nor Heterodoxy can tell what the systemic laws of the actual monetary economy are.

Whether the outcome of the human/system-interaction is good or bad is a politcal question that lies outside of theoretical economics. Theoretical economics explains how the actual economy works - no less, no more.

Narrative vs.Theory

Psychological, sociological or behavioral assumptionism cannot yield anything other than a gossip model of the world. Second-guessing the agents is not economic analysis.

Science deals exclusively with propositions that can in principle be decided by objective means. The rest is opinion, faith, phantasy, motive speculation, allegation, hallucination, myth, paranoia, ink-blot association, psychology, philosophy, in one word: storytelling.

Storytelling is the original mode of communication in the social realm — except science.

Political economics is storytelling and, by default, the natural habitat of confused confusers. Walrasianism, Keynesianism, Marxianism, Austrianism are social narratives and not scientifically valid representations of reality.

"The truth is, most persons, not excepting professional economists, are satisfied with very hazy notions." (Fisher)

In marked contrast, theoretical economics lives up to the standards of material and formal consistency. A scientific theory is the best mental representation of reality that is humanly possible.

Theory starts with a set of objective and consistent axioms.

Paradigm Shift

"The problem is not just to say that something might be wrong, but to replace it by something — and that is not so easy." (Feynman)

"As will become evident, there is more agreement on the defects of orthodox theory than there is on what theory is to replace it: but all agreed that the point of the criticism is to clear the ground for construction." (Nell)

"The moral of the story is simply this: it takes a new theory, and not just the destructive exposure of assumptions or the collection of new facts, to beat an old theory." (Blaug)

"Is it not a fact, which stares at us from the histories of all sciences, that it is much more difficult for the human mind to forge the most elementary conceptual schemes than it is to elaborate the most complicated superstructure when those elements are well in hand?" (Schumpeter)

"The task of producing knowledge against the grain requires imagination." (Mirowski)

"A new idea is extremely difficult to think of. It takes a fantastic imagination." (Feynman)

"The scientific imagination dreams of explanations and laws." (Peirce)

"It is brilliance of imagination which makes the glory of science." (Evans)

"... we know little more now about ‘how the economy works,’ ... than we knew in 1790, after Adam Smith completed the last revision of The Wealth of Nations." (Clower)

Selftest and to watch for

You apply one of these items

• supply-demand-equilibrium,

• general equilibrium,

• marginal utility,

• well-behaved production functions,

• total income = value of output,

• total income = wages + profits,

• I=S,

• wage rate down - employment up,

• behavioral axioms?

Then you are out of science because of unnoticed material or formal inconsistency.

Every economist who uses the concept of equilibrium is scientifically incompetent because she/he failed to notice that equilibrium is an economic nonentity.

Practically this means: as soon as the word equilibrium appears in an economic text it can be thrown into the waste basket. The same holds for all other nonentities.

The vast majority of economists deals mainly with nonentities. This is why Walrasianism, Keynesianism, Marxianism, Austrianism is scientifically worthless.

Since Adam Smith, economic policy guidance has no sound scientific foundations.

To be replaced (1)

The core premises of Orthodoxy are uncertain and false and this fully explains the failure of the research program.

“As with any Lakatosian research program, the neo-Walrasian program is characterized by its hard core, heuristics, and protective belts. Without asserting that the following characterization is definitive, I have argued that the program is organized around the following propositions: HC1 economic agents have preferences over outcomes; HC2 agents individually optimize subject to constraints; HC3 agent choice is manifest in interrelated markets; HC4 agents have full relevant knowledge; HC5 observable outcomes are coordinated, and must be discussed with reference to equilibrium states.” (Weintraub)

The inescapable Paradigm Shift consists of the move from this obsolete hard core to the superior set of structural axioms.

To be replaced (2)

The fundamental equations of macroeconomics have been formulated by Keynes in two lines.

"Income = value of output = consumption + investment. Saving = income - consumption. Therefore saving = investment."

This elementary syllogism is demonstrably false. The demonstration consists in the proof that Keynes could not solve the Profit Puzzle. Neither did Post-Neo-New-Keynesians.

In the most general terms, the economics Paradigm Shift consists in switching from the behavior-centric bottom-up approach to the structure-centric top-down approach. This is comparable to the Copernican turn from geo-centrism to helio-centrism.

Consensus

Economics is a science without scientists. Because they are ignorant of the elementary difference between profit and income, the present generation of economists has not made and cannot make a significant contribution to the discussion about how the actual economy works.

Every orthodox or heterodox economist can convince himself/herself that their profit theory is defective.

Every non-economist can — by applying elementary logic — convince himself that conventional profit theories are false. See 'How the intelligent non-economist can refute every economist hands down'.

Because the profit theory is false the whole of conventional economic theory has to be rejected.

"What is now taught as standard economic theory will eventually disappear, no trace of it will remain in the universities or boardrooms because it simply doesn’t work: were it engineering, the bridge would collapse." (McCauley)

No scientist will ever accept Walrasianism, Keynesianism, Marxianism, or Austrianism. These approaches are logically and/or empirically refuted. This is the actual methodological state-of-art. Walrasians, Keynesians, Marxians, or Austrians are still at the proto-scientific stage. These approaches cannot be improved, only abandoned.

Economists are a public nuisance because they have an opinion on everything but knowledge of nothing.

About the rest of economics

Walrasianism, Keynesianism, Marxianism, Austrianism, MMT, Pluralism are mutually contradictory, axiomatically false, materially/ formally inconsistent. Economics is a failed science.

“There are three classes of people: those who see. Those who see when they are shown. Those who do not see.” Leonardo da Vinci

In economics, the overwhelming majority belongs to Class III. This explains why economics is after 200+ years still at the proto-scientific level.

The obvious task for every economist is to advance from cargo cult science and political agenda-pushing to science. This is absolutely beyond the means of Class III people.

For 200+ years now, economists are not scientists but agenda pushers, useful idiots, clowns in the political Circus Maximus.

Nopopop

This blog does not add to any popular/un- popular opinion.

This blog does not hand out advice about how to avoid taxes, to get rich on the stock market, to be successful in business, to increase the wealth of nations, to run an economy, to maximize welfare, to prevent national/global bankruptcy, to improve the institutional setup of society, to get out of national/global depression, nor about how to save humankind or any subgroup thereof.

This blog is about the true theory of the actual monetary economy.

"In order to tell the politicians and practitioners something about causes and best means, the economist needs the true theory or else he has not much more to offer than educated common sense or his personal opinion." (Stigum)

Focus

Science is of primary interest and importance. Scientists are of secondary interest.

With regard to science, most people lose focus easily because of a natural preference for anecdotes and gossip over facts or subjectivity over objectivity.

Hence, Schumpeter once considered it necessary to remind his habitually disoriented fellow economists: “Remember: occasionally, it may be an interesting question to ask why a man says what he says; but whatever the answer, it does not tell us anything about whether what he says is true or false.”

Science is about true/false and nothing else.

Outlook

To recall, while political economics is storytelling, theoretical economics adheres to scientific standards.

The first task of theoretical economics is to get the axiomatic foundations right. This is what J. S. Mill called the opus magnum. Neither Orthodoxy nor Heterodoxy came up with a reasonable solution to this day. This explains the secular stagnation of economics.

There is no serious alternative to structural axiomatic economics. This is not a matter of opinion but of proof. The sole criteria are material and formal consistency.

All of economics has to be reconstructed from the ground up.

Major economic policy implication

The price mechanism does not work as standard economics hypothesizes. The axiom-based Employment Law states that overall employment increases if the average wage rate increases relative to average price and productivity. This gives one the lever to improve the employment situation all over the world and to fend off deflation without rising debt and without artificial capacity growth. To increase the average price relative to the average wage rate and productivity increases unemployment.

Right policy depends on true theory.

“In order to tell the politicians and practitioners something about causes and best means, the economist needs the true theory or else he has not much more to offer than educated common sense or his personal opinion.” (Stigum)

Lacking the true theory, economists promote for more than 200 years opinion instead of knowledge.
