Likewise, there are inadmissible operations in the process of the definition of a subject matter, e.g. giving two names to the same thing. Trivially, if you are a witness and tell the police that Maria crashed the car against the wall and one minute later that Josef crashed the car and when the police officer remarks there is a contradiction and you answer no, not at all, its the same guy I only call him sometimes Maria and sometimes Joseph you are not regarded as a reliable witness but as a moron or worse, as an economist.<br /><br />So, one more time in slow motion.<br /><br />The elementary production-consumption economy is for a start given by two sectors, i.e. household- and business sector, and defined by three macro axioms (Yw=WL, O=RL, C=PX), two conditions (X=O, C=Yw) and two definitions (Q≡C−Yw, S≡Yw−C).<br /><br />Wage income Yw is a flow from the business to the household sector. Consumption expenditures C is a flow from the household to the business sector. Profit/loss is the DIFFERENCE of these two flows Q≡C−Yw and saving/dissaving is the exact mirror image S≡Yw−C.<br /><br />Because we have TWO sectors we have TWO balances and if we “consolidate” the two sectors we get Q+S=0, that is, trivially, for the economy as a whole there is NO balance. “Consolidation” destroys the information about profit/loss and saving/dissaving that we have gained by splitting up the economy into two sectors.<br /><br />So, we have the flow wage income Yw and the difference of flows (= balance) profit/loss Q and saving/dissaving S. Note that a flow is always positive, while a balance can be either positive or negative. A smart macro accountant knows that to lump a flow and a balance together is a category mistake.#1 Economists commit this methodological blunder since Adam Smith. They still do not realize that by saying total macroeconomic income is the sum of wages and profits they are exposing themselves as incurable incompetent scientists.<br /><br />From the definition Q≡C−Yw follows by mindless symbol manipulation Q+Yw≡C, hence the sum of Q and Yw is already implicitly defined by the initial definition of profit/loss.<br /><br />To introduce an ADDITIONAL definition of the sum of wages and profits is forbidden by the methodological rule called Occam’s Razor. So, Ψ≡Q+Yw is INADMISSIBLE and leads to Ψ≡C which says that two symbols are used for the same thing. The formula states that the word total income (symbol Ψ) and the word consumption expenditures (symbol C) can be used interchangeably.<br /><br />Obviously, this is semantic madness. However, in the formulation total income is equal to the value of output is sounds like a deep economic insight. And so this Humpty Dumpty stuff became the foundation of Keynesianism: “Income = value of output = consumption + investment. Saving = income − consumption. Therefore saving = investment.” (GT, p. 63)<br /><br />Post Keynesians, Anti-Keynesians, and MMTers have not realized until this day that they are caught in a methodological delirium. Because the foundational balances equation of MMT is proto-scientific junk the whole of MMT is proto-scientific junk, that is, brain-dead political agenda pushing for the one-percenters.<br /><br />Egmont Kakarot-Handtke<br /><br />* For full-view links see<br />Political economics: Who hijacks British Labour?<br /><br />https://axecorg.blogspot.de/2018/03/political-economics-who-hijacks-british.html<br /><br />#1 A tale of three accountants<br />https://axecorg.blogspot.de/2017/07/a-tale-of-three-accountants.htmlAXEC / E.K-Hhttps://www.blogger.com/profile/10402274109039114416noreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-56551266602190031832018-03-02T13:12:57.780-05:002018-03-02T13:12:57.780-05:00Why, Egmont, why, do you persist!?Why, Egmont, why, do you persist!?cjnoreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-57069094709132737432018-03-01T06:15:20.565-05:002018-03-01T06:15:20.565-05:00Paul Krugman and economic poultry entrails reading...Paul Krugman and economic poultry entrails reading<br />Comment on Brad DeLong on ‘Paul Krugman Looks Back at The Last Twenty Years of the Macroeconomic Policy Debate’<br /><br />A theory must satisfy TWO criteria ― material AND formal consistency. Logical consistency is secured by applying the axiomatic-deductive method and empirical consistency is secured by applying state-of-the-art testing. This is known since 2000+ years: “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.” (Aristotle, Wikipedia)<br /><br />Paul Krugman, for one, is quite explicit about how he has solved the Starting Problem: “most of what I and many others do is sorta-kinda neoclassical because it takes the maximization-and-equilibrium world as a starting point.”<br /><br />Paul Krugman has not realized since his student days that neoclassical economics has already been dead in the cradle 140+ years ago. In other words, the neoclassical premises are NOT certain, true, and primary. In still other words, neoclassical economics is axiomatically false. And when the axiomatic foundations are false the whole analytical superstructure is false.#1 As a result, the microfoundations approach from Jevons/Walras/Menger onward to DSGE is scientifically worthless.<br /><br />But Paul Krugman is also a Keynesian, sorta-kinda. Keynes built macro on these premises: “Income = value of output = consumption + investment. Saving = income − consumption. Therefore saving = investment.” (GT, p. 63)<br /><br />Unfortunately, Keynes got macroeconomic profit wrong: “His Collected Writings show that he wrestled to solve the Profit Puzzle up till the semi-final versions of his GT but in the end he gave up and discarded the draft chapter dealing with it.” (Tómasson et al.)<br /><br />Because profit is ill-defined the whole theoretical superstructure of Keynesianism is false, in particular all I=S/IS-LM models.#2<br /><br />Paul Krugman, of course, realized nothing and used and praised IS-LM as superior tool for macroeconomic analysis.#3<br /><br />Needless to emphasize that Walrasian microfoundations and Keynesian macrofoundations do not fit together. Therefore, a synthesis of the two is methodological madness since Samuelson’s 1947 textbook.<br /><br />Until this day, Paul Krugman’s economic policy guidance has NO sound scientific foundations but is plucked out of the thin air of political populism. Because both Walrasianism and Keynesianism is axiomatically false, economic policy advice is until this day no different from the poultry entrails reading of the old Roman haruspex.<br /><br />Egmont Kakarot-Handtke<br /><br />#1 For details of the big picture see cross-references Axiomatization<br />http://axecorg.blogspot.de/2014/12/axiomatization-cross-references.html<br /><br />#2 For details of the big picture see cross-references Keynesianism https://axecorg.blogspot.de/2016/09/keynesianism-cross-references.html<br /><br />#3 Mr. Keynes, Prof. Krugman, IS-LM, and the End of Economics as We Know It<br />https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2392856AXEC / E.K-Hhttps://www.blogger.com/profile/10402274109039114416noreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-56392185697389609872018-02-28T12:45:19.879-05:002018-02-28T12:45:19.879-05:00Forget Keynes
Comment on Asad Zaman on ‘Understand...Forget Keynes<br />Comment on Asad Zaman on ‘Understanding Macro: The Great Depression’<br /><br />There is political economics and theoretical economics. The main differences are: (i) The goal of political economics is to successfully push an agenda, the goal of theoretical economics is to successfully explain how the actual economy works. (ii) In political economics anything goes; in theoretical economics, the scientific standards of material and formal consistency are observed.<br /><br />Political economics has produced NOTHING of scientific value in the last 200+ years. This is the track record: provably false<br />• profit theory, since 200+ years,<br />• Walrasian microfoundations (including equilibrium), since 140+ years,<br />• Keynesian macrofoundations (including I=S/IS-LM), since 80+ years.<br /><br />Heterodoxy claims that Orthodoxy from Walras/Marshall to DSGE is false. This, of course, is true. However, Heterodoxy claims also that Keynesian economics is a valid replacement for Orthodoxy. This is provably false. Keynesianism, too, is proto-scientific junk.#1<br /><br />Asad Zaman argues: “Lord John Maynard Keynes invented the entire field of macroeconomics in response to the Great Depression in 1929, which could not be understood according to economic theories dominant until then.”<br /><br />Keynes, too, was an incompetent scientist and if there ever was a political agenda pusher then he. Keynes saw the necessity of a paradigm shift but he messed up the move from microfoundations to macrofoundations.<br /><br />Fact is: Walrasianism, Keynesianism, Marxianism, Austrianism is mutually contradictory, axiomatically false, materially/formally inconsistent and ALL approaches got profit theory, employment theory, and the theory of money wrong.<br /><br />Asad Zaman argues: “It should be immediately obvious that active government involvement in creating full employment helps the bottom 90%. It is slightly less obvious that monetary expansion, which may create inflation, is also helpful to the poorer segment of society. This is because the poor are generally borrowers of money, so the value of their debt in real terms becomes reduced. Similarly, easy money makes it easier for them to borrow. At the same time, Keynesian policies hurt the top 1%.”<br /><br />The claim that Keynes fought for the cause of ninety-nine-percenters and against the one-percenters is false. In effect, the opposite is true.#2<br /><br />Heterodoxy’s repetitive critique of Orthodoxy has run into the dead end.#3 Heterodoxy, too, is scientifically worthless political economics. It is time to forget the whole proto-scientific blather and to move on: “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)<br /><br />Time to bury failed/fake scientists for good and to leave the creepy intellectual graveyard of orthodox and heterodox economics behind.<br /><br />Egmont Kakarot-Handtke<br /><br />#1 For details see<br /><br />Keynes’ intellectual nonexistence<br />http://axecorg.blogspot.de/2017/12/keynes-intellectual-non-event.html<br /><br />How Keynes got macro wrong and Allais got it right<br />http://axecorg.blogspot.de/2016/09/how-keynes-got-macro-wrong-and-allais.html<br /><br />Keynes’ Employment Function and the Gratuitous Phillips Curve Disaster<br />https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2130421<br /><br />#2 For details see<br /><br />Who or what exactly did Keynes save?<br />http://axecorg.blogspot.de/2016/11/who-or-what-exactly-did-keynes-save.html<br /><br />Keynes, Lerner, MMT, Trump and exploding profit<br />https://axecorg.blogspot.de/2017/12/keynes-lerner-mmt-trump-and-exploding.html<br /><br />Fiscal policy and the Humpty Dumpty Fallacy<br />https://axecorg.blogspot.de/2018/02/fiscal-policy-and-humpty-dumpty-fallacy.html<br /><br />#3 Economics: communication without content<br />https://axecorg.blogspot.de/2018/02/economics-communication-without-content.htmlAXEC / E.K-Hhttps://www.blogger.com/profile/10402274109039114416noreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-3486774635613557962018-02-27T14:22:56.891-05:002018-02-27T14:22:56.891-05:00Capitalism is a debt based ponzi scheme of the heb...Capitalism is a debt based ponzi scheme of the hebrews.

Commen...Fiscal policy and the Humpty Dumpty Fallacy<br />Comment on ProGrowthLiberal on ‘A Kennedy-Reagan-Trump Fiscal Policy?’<br /><br />Economists think since the Classicals that saving and investment are two sides of the same coin. And since investment is good for growth, saving here and now makes us richer in the future. According to Adam Smith, the saver/capitalist is the true hero of wealth creation.<br /><br />Brad deLong updates the story as follows: “The economy’s savings-investment effort rate, s, has two parts: private and government saving: s=sp+sgs=sp+sg. The private savings rate spsp is very hard to move by changes in economic policy. Policy changes that raise rates of return on capital ― interest and profit rates ― both make it more profitable to save and invest more but also make us richer in the future, and so diminish the need to save and invest more.”<br /><br />Note that the saving-investment link is hardwired in the economist’s brain. Keynes put it thus: “Income = value of output = consumption + investment. Saving = income − consumption. Therefore saving = investment.” (GT, p. 63)<br /><br />With regard to the currently increasing government deficit this makes the representative economist wonder: “We have been asking the same question since 1981 ― how can anyone argue that a fall in national savings is good for long-term growth? We still have not received a coherent answer.”<br /><br />The coherent answer is that economists get the relationship between saving and investment wrong since Adam Smith.<br /><br />To make matters short, the axiomatically correct relationships are given here without further explanation.#1 It holds, with Qm monetary profit/loss, Sm monetary saving/dissaving, I investment expenditures, G government spending, T taxes:<br /><br />(i) Qm=−Sm in the elementary production-consumption economy,<br /><br />(ii) Qm=I−Sm in the elementary investment economy,<br /><br />(iii) Qm=(G−T)+I−Sm in the investment economy with government deficit/surplus.<br /><br />The point to grasp is that there is NO such thing as an equality/identity/equilibrium of household/government sector saving and business sector investment, and NEVER was, and NEVER will be.<br /><br />According to (i) household sector saving produces a loss in the business sector and according to (iii) a government sector deficit produces a profit in the business sector. Investment I is a variable that moves INDEPENDENTLY from both private and public saving/dissaving.<br /><br />Where, then, does the notorious identity/equality of saving/investment come from?<br /><br />Let us take equation (ii) and play a semantic shell game. Enter Humpty Dumpty who introduces a redundant definition by saying that profit may be called “saving of the business sector” and that this “saving” can be added up with saving of the household sector to “total saving” Σ thus<br />(a) Σ≡Qm+Sm and now (ii) is rewritten<br />(b) Qm+Sm=I and then, hey presto,<br />(c) Σ≡I that is, “total saving” is “by definition” identical to investment or in the usual sloppy parlance “saving equals investment” which obviously contradicts (ii) and ― strangely enough ― makes profit invisible.<br /><br />This methodological idiocy is at the bottom of all I=S/IS-LM models and Post Keynesian economics in general.#2<br /><br />So, the coherent answer to the question why a fall in national savings could be good for long-term growth is that it boosts profit. The representative economist never got this because the profit theory is false since Smith/Ricardo.#3 This means that economic policy guidance in general, and fiscal policy in particular, NEVER had sound scientific foundations.<br /><br />Egmont Kakarot-Handtke<br /><br />#1 For details of the big picture see cross-references Refutation of I=S<br />http://axecorg.blogspot.de/2015/01/is-cross-references.html<br /><br />#2 Why Post Keynesianism Is Not Yet a Science<br />https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1966438<br /><br />#3 Ricardo, too, got profit theory wrong.

One thesis would be that Reagan wanted to eventually starve the beast (he never did) and the other thesis being that those payroll tax increases in 1983 were to pay for the cuts in taxes for the rich rather than prefund our Social Security benefits.

We also know that national savings did fall in the early 1980's. I guess there is some explanation for this fact. But note the Barro view of the world still does not address DeLong's or my query. <br /><br />It is interesting that Greg Mankiw's first macroeconomic textbook laid out very nicely the story I have suggested. Of course one has to wonder why he supported Bush43's tax cuts. At least he was not so keen on Trump's fiscal policy.
