Vulgar Austrians do not Understand Austrian Price Theory

Certain vulgar and ignorant internet Austrians actually seem to believe that Austrian price theory does not have a fundamental role for the idea of flexible prices and wages that, in market trades by buyers and sellers, are moved towards their market-clearing levels to clear product markets by equating quantities demanded with quantities supplied, so that economic coordination and full use of resources are achieved.

Well, here is a clear statement of the Austrian view of prices by Thomas C. Taylor in his An Introduction to Austrian Economics (1980), a book republished by Ludwig von Mises Institute:
“The day-to-day tendency in the market is toward the establishment of an equilibrium price for each particular consumer good. Prevailing prices tend toward that price at which quantity supplied and quantity demanded are equal, a movement that attests to the price system’s capacity to coordinate the actions of persons engaged in different activities. The typical depiction of this tendency on a graph shows the equilibrium price at the point at which the market supply-and-demand curves intersect. Any price above or below the equilibrium price cannot persist because such a price will result, respectively, in either frustrated sellers or frustrated buyers. Prices are reduced by sellers if the market price is too high to clear the quantity offered; prices are bid upward by buyers if the price is too low to induce sellers to offer a quantity ample enough to satisfy the buyers’ demand.” (Taylor 1980: 56).
This passage appears to be a straightforward descriptive statement of how Austrians view real world prices.

Of course, Austrians no doubt see a good deal of rigidity and inflexibility of real world prices, but they attribute this to “evil” interference by government and the deleterious influence of trade unions, so that no doubt Austrians can also see the passage above as a prescriptive vision of how a free market should set prices.

But there isn’t really any serious contradiction here: it can function both as a rough descriptive statement of how prices are set in a modern market economy (with qualifications to explain some price rigidities) and an ideal prescriptive statement of how prices ought to be set in a free market.

I could cite many other passages confirming this. A sample follow below:
(1) “In fact, pricing on the market is not an act of will by sellers. Businessmen do not determine their selling prices on the basis of whether they feel greedy or ‘responsible’ that morning. The entire apparatus of economic theory, built up over centuries, is devoted to demonstrating a great truth: that prices are set only by the demand of purchasers (how much of a good or service purchasers will buy at any given price), and by the supply or stock of the good.

Prices are set so as to ‘clear the market’ by equating supply and demand; at the market price the supply of a good will exactly equal the amount of the good that people are willing to buy or hold. If the demand for the good increases, purchases will bid the price up; if the supply increases, the price will fall. Demanders consist of consumers, whose purchases are determined by the values they place on the goods, and various producers or businessmen, whose demands are determined by how much they expect consumers to pay for the final product.” (Rothbard 2006: 390).

(2) “We know from ‘microeconomic’ analysis that if there is a ‘surplus’ of something on the market, if something cannot be sold, the only reason is that its price is somehow being kept too high. The way to cure a surplus or unemployment of anything, is to lower the asking price, whether it be wage rates for labor, prices of machinery or plant, or of the inventory of a retailer.” (Rothbard 2006b: 44).

(3) “A worse problem is that, since the 1930s, government and its privileged unions have intervened massively in the labor market to keep wage rates above the market-clearing wage, thereby insuring ever higher unemployment.” (Rothbard 2006b: 45).

(4) “Similarly, most economists would readily admit that keeping the price of any good above the amount that would clear the market will cause unsold surpluses to pile up. Yet, they are reluctant to admit this in the case of labor. …. In a free market, wage rates will tend to adjust themselves so that there is no involuntary unemployment, i.e., so that all those desiring to work can find jobs. Generally, wage rates can only be kept above full-employment rates through coercion by government, unions, or both.” (Rothbard 2008: 43).

(5) “Private business prices its goods and services to ‘clear the market,’ so that supply equals demand, and there are neither shortages nor goods going unsold.” (Rothbard 2006a: 259).

(6) “There is no reason why prices cannot fall low enough, in a free market, to clear the market and sell all the goods available. If businessmen choose to keep prices up, they are simply speculating on an imminent rise in market prices; they are, in short, voluntarily investing in inventory. If they wish to sell their ‘surplus’ stock, they need only cut their prices low enough to sell all of their product. But won’t they then suffer losses? Of course, but now the discussion has shifted to a different plane.” (Rothbard 2008: 56).

(7)The characteristic feature of the market price is that it equalizes supply and demand. The size of the demand coincides with the size of supply not only in the imaginary construction of the evenly rotating economy. The notion of the plain state of rest as developed by the elementary theory of prices is a faithful description of what comes to pass in the market at every instant. Any deviation of a market price from the height at which supply and demand are equal is – in the unhampered market – self-liquidating.” (Mises 2008: 756–757).

(8) “The driving force of the market process is provided neither by the consumers nor by the owners of the means of production – land, capital goods, and labor – but by the promoting and speculating entrepreneurs. These are people intent upon profiting by taking advantage of differences in prices. Quicker of apprehension and farther-sighted than other men, they look around for sources of profit. They buy where and when they deem prices too low, and they sell where and when they deem prices too high. They approach the owners of the factors of production, and their competition sends the prices of these factors up to the limit corresponding to their anticipation of the future prices of the products. They approach the consumers, and their competition forces prices of consumers’ goods down to the point at which the whole supply can be sold.” (Mises 2008: 325).

(9) “It is ultimately always the subjective value judgments of individuals that determine the formation of prices …. . Market prices are entirely determined by the value judgments of men as they really act.

If one says that prices tend toward a point at which total demand is equal to total supply, one resorts to another mode of expressing the same concatenation of phenomena. Demand and supply are the outcome of the conduct of those buying and selling. If, other things being equal, supply increases, prices must drop. At the previous price all those ready to pay this price could buy the quantity they wanted to buy. If the supply increases, they must buy larger quantities or other people who did not buy before must become interested in buying. This can only be attained at a lower price.

It is possible to visualize this interaction by drawing two curves, the demand curve and the supply curve, whose intersection shows the price.” (Mises 2008: 329–330).

(10)The market interaction brings about a price at which demand and supply tend to coincide. The number of potential buyers willing to pay the market price is large enough for the whole market supply to be sold. If government lowers the price below that which the unhampered market would set, the same quantity of goods faces a greater number of potential buyers who are willing to pay the lower official price. Supply and demand no longer coincide; demand exceeds supply, and the market mechanism, which tends to bring supply and demand together through changes in price, no longer functions.” (Mises 2011: 101).

(11) “Rothbard presumed that in individual markets, the law of one price dominated, and that market clearing happened rapidly and smoothly … . Just as in conventional neoclassical economics, general equilibrium, the evenly rotating economy (ERE), was the direction in which the economy was headed.” (Vaughn 1994: 97).

(12) “Mises conceives the market process as coordinative, ‘the essence of coordination of all elements of supply and demand.’ This means that the structure of realized (disequilibrium) prices, which continually emerges in the course of the market process and whose elements are employed for monetary calculation, performs the indispensable function of clearing all markets and, in the process, coordinating the productive employments and combinations of all resources with one another and with the anticipated preferences of consumers.” (Salerno 1993: 124).

(13) “The market process will tend to establish a price that clears the market: all sellers willing to sell at the market price will be able to do so, and all buyers willing to buy at that price will also be able to do so. …. If these dynamics of supply and demand change, the market process will adjust the price to the new realities.” (Callahan 2004: 76).

(14) “The modern, subjectivist theory of prices does not assume that people have ‘perfect knowledge’ of the market. On the contrary, catallactics can explain the formation of actual prices in the real world. Indeed, those mainstream economists who study static ‘equilibrium’ outcomes ignore the crucial process in which speculative entrepreneurs drive the market toward equilibrium. By spotting disequilibrium (but real-world) prices and acting to seize the profit opportunities that they entail, it is the entrepreneurs who move the whole system toward the equilibrium state that the mathematical economists take for granted as the starting point of analysis. By buying ‘underpriced’ goods or factors of production, and selling ‘overpriced’ ones, the entrepreneurs push up the former and push down the latter prices, earning profits and equilibrating the economy.” (Murphy and Gabriel 2008: 133–134).

(15) “Competitive prices are the outcome of a complete adjustment of the sellers to the demand of the consumers. Under the competitive price the whole supply available is sold, and the specific factors of production are employed to the extent permitted by the prices of the nonspecific complementary factors. No part of a supply available is permanently withheld from the market, and the marginal unit of specific factors of production employed does not yield any net proceed. The whole economic process is conducted for the benefit of the consumers.” (Mises 2008: 354).

(16) “The market is always tending quickly toward its equilibrium position, and the wider the market is, and the better the communication among its participants, the more quickly will this position be established for any set of schedules. Furthermore, a growth of specialized speculation will tend to improve the forecasts of the equilibrium point and hasten the arrival at equilibrium. However, in those cases where the market does not arrive at equilibrium before the supply or demand schedules themselves change, the market does not reach the equilibrium point. It becomes continuous, moving toward a new equilibrium position before the old one has been reached. (29)

[note]
(29) This situation is not likely to arise in the case of the market equilibria described above. Generally, a market tends to ‘clear itself’ quickly by establishing its equilibrium price, after which a certain number of exchanges take place, leading toward what has been termed the plain state of rest—the condition after the various exchanges have taken place.” (Rothbard 2009: 143, with n. 29).

(17) “Price control measures paralyze the working of the market. They destroy the market. They deprive the market economy of its steering power and render it unworkable.

The price structure of the market is characterized by its tendency to bring supply and demand into balance. If the authority attempts to fix a price different from the market price, this situation cannot prevail. In the case of maximum prices, there are potential buyers who cannot buy although they are ready to pay the price fixed by the authority, or even to pay a higher price. Or there are—in the case of minimum prices—potential sellers who cannot find buyers even though they are willing to sell at the price established by the authority, or even to sell at a lower price. The price is no longer the means of segregating those potential buyers and sellers who may buy or sell from those who may not. A different principle of selection has to come into operation. It may be that only those who come first or those who occupy a privileged position due to particular circumstances (personal connections, for instance) will actually buy or sell. But it may also be that the authority itself takes over the regulation of distribution. At any rate the market is no longer able to provide for the distribution of the available supply to the consumers. If chaotic conditions are to be avoided, and if neither chance nor force is to be relied upon to determine distribution, the authority has to undertake this task by some system of rationing.” (Mises 1998 [1940]: 26).

(18) “The price structure of the market decides what will be produced, how, and in what quantity. Through the structure of prices, wages, and interest rates the market brings supply and demand into balance and sees to it that each branch of production will be as fully occupied as corresponds to the volume and intensity of the effective demand. Thus capitalist production derives its meaning from the market. Of course, a temporary imbalance between production and demand can occur, but the structure of market prices makes sure that the balance is reestablished in a short time. Only when the mechanism of the market is disturbed by external interventions is the effect of market prices on the regulation of production prevented; they are disturbances that no longer can be remedied by the automatic reactions of the market, disturbance that are not temporary but prolonged.” (Mises 2002a [1931]: 170).

(19) “Entrepreneurs try to supply those goods whose sale promises them the highest possible profit. But it is the market that decides where profits are earned and losses suffered. If consumers demand more of a product, then its price rises; if they demand less, then the price falls. If entrepreneurs produce only those goods whose sale promises to bring them profits, then that means they are following the wishes of the consumers. It is the market, therefore, that directs a capitalist economy, based on the private ownership of the means of production. The changing prices of the market bring supply and demand into equilibrium. The market price—called the ‘natural price’ by the Classical economists and the ‘static price’ by modern economists—finds its level at a point at which no prospective buyer who is ready to pay the market price leaves the market unsatisfied, and no prospective seller who is willing to accept the market price leaves the market with unsold goods.” (Mises 2002b [1933]: 209).

(20) “The crisis from which the world is suffering today is the crisis of interventionism and of national and municipal socialism; in short, it is the crisis of anticapitalist policies. Capitalist society—there is no difference of opinion about this—is governed by the workings of the market process. Market prices bring supply and demand into balance and determine the direction and extent of production. The capitalist economy gets its meaning from the market. If the function of the market as regulator of production is permanently undermined by an economic policy that attempts to set prices, wages, and interest rates other than in the way the market forms them, then a crisis will surely occur.” (Mises 2002c [1932]: 191).

(21) “The aim of price control is to decree prices, wages, and interest rates different from those fixed by the market. Let us first consider the case of maximum prices, where the government tries to enforce prices lower than the market prices.

The prices set on the unhampered market correspond to an equilibrium of demand and supply. Everybody who is ready to pay the market price can buy as much as he wants to buy. Everybody who is ready to sell at the market price can sell as much as he wants to sell. If the government, without a corresponding increase in the quantity of goods available for sale, decrees that buying and selling must be done at a lower price, and thus makes it illegal either to ask or to pay the potential market price, then this equilibrium can no longer prevail. With unchanged supply there are now more potential buyers on the market, namely, those who could not afford the higher market price but are prepared to buy at the lower official rate. There are now potential buyers who cannot buy, although they are ready to pay the price fixed by the government or even a higher price.” (Mises 2010 [1944]: 61).

(22) “In the capitalistic economy, it is consumer demand that determines the pattern and direction of production, precisely because entrepreneurs and capitalists must consider the profitability of their enterprises.

An economy based on private ownership of the factors of production becomes meaningful through the market. The market operates by shifting the height of prices so that again and again demand and supply will tend to coincide. If demand for a good goes up, then its price rises, and this price rise leads to an increase in supply. Entrepreneurs try to produce those goods the sale of which offers them the highest possible gain. They expand production of any particular item up to the point at which it ceases to be profitable. If the entrepreneur produces only those goods whose sale gives promise of yielding a profit, this means that they are producing no commodities for the manufacture of which labor and capital goods must be used which are needed for the manufacture of other commodities more urgently desired by consumers.” (Mises 2006 [1931]: 156–157).

(23) “Entrepreneurs, capitalists, landowners, and workers are participants in the market, and they demand prices for their services. The consumers answer these price demands through their buying or abstention from buying on the market. From this interaction there results the market, on the basis of which supply and demand are brought into balance. Through the process of price formation the market performs its function as regulator of production.” (Mises 2002d [1932]: 201).

(24) “Persons with goods or services they hope to sell must continually experiment to discover the ‘market price’ of any particular item. As the students will have learned from the classroom auctions, it is possible to determine, by continued bargaining, the price at which an item will ‘clear the market’ at any particular moment. At that price, determined by the relative eagerness and subjective values of owners or potential sellers and would-be buyers, the number of units of a good or service wanted and the number offered will be the same. But no one can know in advance what this price will be.” (Greaves* 1984: 51).

* Bettina Bien Greaves was a student of Mises.

(25) “… selling prices will tend toward the market-clearing level, and need not hit the mark every time the firm sets it price. Despite the firms’ lack of perfect knowledge of [demand] and [supply] conditions, they are motivated to seek market-clearing outcomes and avoid disequilibrium outcomes.

For one thing, there is the economic incentive to maximize profits. As we have seen, surplus and shortage outcomes cause the firm less profit than otherwise under the given demand and supply conditions. Thus, in the case of a surplus, the firm will have to slash its [price] below the planned level, whereas in the case of a shortage the firm has missed an opportunity for greater profits by setting its [price] too low or producing less than the market was ready to absorb.

On the other side of this coin is the fact that, of the three possible market outcomes—market-clearing, surplus, or shortage—only market-clearing outcomes validate the firm’s expectations and strengthen its confidence in its ability to judge market conditions.
In contrast, surpluses and shortages are truly disappointments—sources of regret and diminished confidence.” (Shapiro* 1985: 208).

* We told at the Mises Institute that “Murray Rothbard just loved this Austrian text on microeconomic theory. In fact, he thought it was the best text available.”

(26) “As we have indicated, because of uncertainty and ignorance, firms will experience shortages and surpluses about as often as market-clearing. In a free market, such disequilibrium outcomes would tend to be shortlived or temporary. However, if and when the surpluses and shortages become persistent or long-lasting—a situation thoroughly inconsistent with free-market conditions— the cause must be sought elsewhere: (1) in government price-fixing or other interventions, and (2) non-profit pricing policies.” (Shapiro 1985: 209).

(27) “The concept of a glut for a single good is easy enough to understand: there is more supply on the market than demand at the offered price. A glut can be alleviated by a fall in the price of that good. The producers of the good may take a loss if the market price is below their costs, but the market can always clear at some price.”
Blumen, Robert. 2014. “Say’s Law and the Permanent Recession,” Mises Daily, February 28,

(28) “An equilibrium price is one in which quantity supplied equals quantity demanded. Graphically, it occurs at the intersection of the supply and demand curves. The market tends toward equilibrium: If the current price is above the equilibrium price, there is an excess supply (‘surplus’) and sellers reduce their asking price. If the current price is below the equilibrium price, there is an excess demand (‘shortage’) and buyers increase their offer price.

There is a tendency for one price to rule over a market. If there weren’t, then arbitrage opportunities would exist; a middleman could buy low and sell high.” (Murphy 2006: 19–20).

(29) “Because of diminishing marginal utility, an individual’s demand curve cannot be upward sloping. The summation of each potential buyer’s demand schedule gives the market demand schedule, i.e., the number of units demanded at each hypothetical money price for the good. The determination of the market supply schedule is also comparable to the barter analysis. The equilibrium (money) price is the (money) price at which quantity supplied equals quantity demanded.” (Murphy 2006: 42).

(30) “A surplus (or a ‘glut’) occurs when producers are trying to sell more units of a good or service than consumers want to purchase (at a particular price). A shortage occurs when consumers want to buy more units than producers want to sell (at a particular price). In this context, the equilibrium price (or the market-clearing price) is the one at which the amount supplied exactly equals the amount demanded. If the market is in equilibrium, there is no surplus and no shortage.” (Murphy 2010: 156–157).

(31)Equilibrium price / market-clearing price: The price at which producers want to sell exactly the number of units that consumers want to purchase. On a graph, the equilibrium price occurs at the intersection of the supply and demand curves. …

Equilibrium quantity: The number of units that producers want to sell, and consumers want to buy, at the equilibrium price. On a graph, the equilibrium quantity occurs at the intersection of the supply and demand curves.” (Murphy 2010: 385).
There is no way to interpret these except as saying that flexible prices and wages converging towards their market-clearing levels have a fundamental role in Austrian economic theory and in the real world.

The only alternative to this is that Austrian price theory is not even meant to describe real world price setting. This bizarre possibility would entail that Austrian price theory is devoid of any serious description of reality. I wonder if vulgar Austrians really think this.

  1. After the bit you highlight Rothbard (2008) goes on to say "If businessmen choose to keep prices up, they are simply speculating on an imminent rise in market prices; they are, in short, voluntarily investing in inventory".

    Isn't this close to what Post-Keynsians also believe albeit stated in rather different terms ? Businesses targeting price+markup have a model where they will increase inventories rather that lower prices in the face of lower demand. I assume that Post-Keynesian do accept that if businesses did actually lower prices then the sales of physical goods would increase ?

    Interestingly Rothbard appears to be making a point more subtle than just "lower prices will always clear the market" as he goes onto say "But won’t they then suffer losses? Of course, but now the discussion has shifted to a different plane" which implies he did understand some of the complexities of market-clearing prices and why businesses might have models that were not always flex-price.

    1. (1) " Rothbard (2008) goes on to say "If businessmen choose to keep prices up, they are simply speculating on an imminent rise in market prices; they are, in short, voluntarily investing in inventory".

      Yes, indeed he does, but with respect to administered price firms, what Rothbard says there is still absurd.

      Why? Because the product prices of administered price firms are hardly going to be subject to an "imminent rise" for the very reason that they are ALREADY fixed by price administration. Rothbard is just assuming flexible prices fluctuating in response to demand and supply.

      (2) "Isn't this close to what Post-Keynsians also believe albeit stated in rather different terms ? "

      Not at all. The firms that add goods to inventory are not "speculating on an imminent rise in market prices". They are cutting production and employment in response to demand falls and selling their product at the same price.

      (3) And, finally, Rothbard shows not the slightest understanding of administered prices.

      If you can point to a passage in his writings where he does so, then cite it.

  2. I'm not claiming that Rothbard was a closet Post-Keynsian but just that his analysis is more subtle that the caricature that you present - even judged on the basis of your selective quotes.

    On "they are simply speculating on an imminent rise in market prices". Of course Rothbard's underlying assumption is of a market clearing price that needs to be found - but what I was highlighting is that Rothbard does not assume that this price is found instantly and at all times. Sometimes businesses will accumulate stock rather reducing prices.

      And I never said he did. So at that point nothing substantive is left of your original criticisms.

  3. Economics has a lot of short run long run dichotomies.

    Far be it from me to defend the Austrians, whom i spend a great deal of time attacking, but here goes.

    I dont defend them in the short run. No one denies the central truth of how prices are set by a seller. This is not a two-way auction market like the financial markets. But if consumers won't buy, then the prices massive sellers set will have little meaning. First their inventories will pile up, then they will slash employment. If that doesn't work, they'll slash production. Finally, if THAT doesn't work they'll eventually as a last resort cut prices, to get rid of massive unsold inventory. (typically they'll have temporary sales, massive price cuts for a limited time ONLY!, what Keynes referenced in the General Theory as cutting prices in the present relative to the future, which he agrees will work in the absence of debt deflation)

    Sellers set prices through a central administrative cost plus mark up in the short run (BFD?) but they will make money in the long run only if consumers hit those prices

    1. But this isn't refuting anything about administered prices. Yes, a consumer needs to think they will subjectively value a good to want to buy it.

      But that doesn't mean an individual can affect the price! Market power is firmly in the hands of the administered price producers: you take their price or you can't have the product.

  4. LK,

    it's obvious that those idiots over at Murphy's blog are in a state of denial.

    Denial:

    "in psychiatry, a defense mechanism in which the existence of unpleasant internal or external realities is kept out of conscious awareness. By keeping the stressors out of consciousness, they are prevented from causing anxiety".

    "An unconscious defense mechanism characterized by refusal to acknowledge painful realities, thoughts, or feelings."

    "An unconscious defense mechanism used to allay anxiety by denying the existence of important conflicts."

  5. But an individual can affect the price at….
    you guessed it, the MARGIN.

    Any way, massive sellers try and get as many customers as possible, individuals have many common preferences, and consumers as a GROUP have long run veto power over the decisions of these administered price producers, so whats the BFD? (big freaking deal) about administered prices versus prices set in a two-way auction? I find it odd that you spend so much time on this in your blog, given that even the most conservative neoclassical (i can't speak for the Austrians) will admit to administered prices and monopolistic imperfect competition. (The entire New Keynesians project is about adding real world frictions like these!)

    A question for you. If individuals don't matter, why have companies recently been trolling social media sites for opinions about their products.

    (By the way, no business will get very far if it has the psychological mindset that even one customer doesn't matter)

    1. I did not mean to say that individuals do not matter in any sense. Of course their tastes, preferences and demand matter and are important for businesses.

      I said that one individual is unlikely to be able to change an administer price. You pay it or you can't have that good.

    2. Administered prices aren't "frictions", they're just how prices are set in many cases. Describing them as "frictions" assumes that neoclassical price theory is the correct underlying model, but that some things get in the way of it working smoothly, for a while. That's BS.

  7. Lord Keynes,

    I was wondering what do you think of Steve Keen's comment in his article, "Seductive Supermodels of Supply and Demand."

    He concludes at first that you are correct, that real world prices are set by cost mark up.

    But then he throws a curve ball at the end, but fails to explain what he means. So I was curious if you knew the answer? Do you have the "follow up" article that Keen's mentions, because I can't find it.

    Keen: "But it does seem to decide the case in favour of the classicals for the real world: prices must be set by a mark-up on costs, rather than by the ‘twin blades’ supply and demand."

    But then Keen adds: "That’s the opinion I held, until a crucial step in generalising my model of Minsky’s Financial Instability Hypothesis implied that, at a macro level, the two models are identical."

    1. I'm not sure what he means by that final remark, but he says:

      "That’s the opinion I held, until a crucial step in generalising my model of Minsky’s Financial Instability Hypothesis implied that, at a macro level, the two models are identical. I’ll get on to that – and the role of prices in economic instability – in the next post in this series."

      Presumably the answer lies in the next post on that site. Unfortunately, I couldn't locate it in my quick look through the page.

    2. If I find it, I'll let you know.

    3. I hope he doesn't mean what he says here. Financial markets are flexi-price market to only some extent. Can the economy be thought of as being based on the interaction of the "twin blades" at a macro-level? That would be the standard AS-AD model. That model is extremely problematic. I hope Keen is not going down that route...

    4. Lord Keynes,

      I think it might be this article:

      http://debunkingeconomics.com/2013/06/is-capitalism-inherently-unstable-4/

      If I were Neoclassical, I would have shoved in a “marginal cost equals price” (Freshwater) or “marginal cost equals marginal revenue” (Saltwater) assumption here—both of which are empirically and logically false. As a Post Keynesian, I could have shoved in a markup pricing equation, but that felt like a fudge: I preferred to try deriving the pricing equation from model itself.

      Here I found myself in a bind. The one way I could do that was to argue that the price level would adjust under the pressure from the flow of monetary demand on one side, and the pressure of physical supply on the other. This isn’t the same as Neoclassical supply and demand—which wrongly assumes that the “supply curve” is given by (marginal) costs and the “demand curve” by (marginal) revenue, and it imagines that prices are set in either a timeless equilibrium (Freshwater) or a friction-delayed convergence to “marginal cost equals marginal revenue” (Saltwater).

      But it felt like it. Having spent four decades railing against Neoclassical thinking, it felt like a defeat to start from “let’s assume prices adjust to supply and demand”.

    LOL. If the shoe fits…...

    1. Steve has another surprise up his sleeve for us, if I can find the next article in this series. It would be #5 (I cited 3 and 4 above)

      Great. But I grit my teeth and gave it a go. And got the surprise that I’ll detail in the next post in this (ever-lenghtening!) series.

  9. From Wiki

    The law of the identity between global demand and global supply

    Since output finds its economic measure in the payment of wages and since income is initially formed by this same payment, quantum economists hold that global supply and demand are jointly determined as the two aspects of one and the same reality. They maintain that global or macroeconomic demand is defined, irrespective of economic agents’ behaviour, by the amount of income available within a given economy, and that global or macroeconomic supply is determined by the economic measure of produced output. Both terms of the equation D = S being measured by the same amount of wages, quantum economists conclude that their relationship is necessarily that of an identity and that the present economic disequilibria have to be explained starting from and consistently with this identity.

    1. I am not sure how this comment is relevant to the original post, but, anyway, I've not heard of "quantum economics" before, and the rest of the Wikipedia page does not inspire any confidence in it:

      Léon Walras’s view of money as a purely numerical, adimensional object („Le mot franc est le nom d'une chose qui n'existe pas“[4])is another intuition espoused by quantum economists. They also revive Jean-Baptiste Say’s Law, although in a slightly different sense than usually retained.

      It looks like support some form of Say's law and the mistaken notion that money is a mere neutral numéraire.

    2. Just remembered that you recently linked to a paper in the quantum economics / monetary emissions tradition yourself. And reviewed it quite favourably, too.

      http://socialdemocracy21stcentury.blogspot.ch/2013/05/review-of-keynesian-economics-on.html

      They deduce their version of Say's Law from macroeconomic accounting identities, starting with income = output (as an identity as opposed to an equilibrium condition). It's more of an analytical tool for developing an understanding of productive vs. non-productive (rentier) elements in an economy, as far as I've understood. Some of it's a bit strange to me, I admit, but other parts are quite brilliant, I find.

  10. Sorry, it wasn't directed at your post, but more at the discussion on Steve Keen above. Should have clarified.
    Anyway, they consider themselves part of the Post Keynesian tradition. There's a good indtrodution in Sawyer / Arestis' 'A Handbook of Alternative Montary Economics' (which one can download from somewhere, I recall). The framework takes some getting used to, but in many ways their definitions are clearer and crisper than most others I've come across. In any case, it's not what one might think it is at first sight, coming from standard PK or even MMT.
