This article is the first part of a 20 pages long paper written as a course at the University of Aarhus, School of Economics and Management. The title of the original paper is “An Austrian Critique of Transaction Cost Theory”. The original paper was divided into two parts, first a walkthrough of the Austrian understanding of the market process, second a critique of Transaction Cost Theory. The paper in its totality can be found here.
I have come to the conclusion, that even though the there might be a few out there, who will find the critique interesting; the most relevant part for Liberator is definitely the first part. Hopefully this article can serve as an introduction to Austrian Market Theory for the student of economy or business, who has not read any or little Austrian Market Theory.
I am sorry, that I have not had the time to translate my paper into Danish. But as most of you are fluent in English (at least those of you, who have an interest in economics,) I have simply chosen not to use any of my very limited time on a translation. I will also like to thank Jacob Hedegaard for very helpful comments on the draft version.
In this article, I will go through the Austrian understanding of the market process. First I will introduce the notion of human action and the Hayekian knowledge problem. With the notion of human action, the entrepreneur can be introduced, who will play a crucial role in how the market solves the Hayekian Knowledge Problem. At last it will all be put together, so it becomes clear that Austrian economics is not an analysis of equilibrium, but an analysis of the market process and disequilibrium. Hereafter I will give a short criticism of equilibrium analysis and afterwards introduce the Market Theory Problem (MTP). The MTP is mainly a tool for criticizing other market theories, but I have kept it in this article, as it deepens the critique of equilibrium analysis.

Human Action

I will in this section describe the basic notion of human action as theorized by Ludwig von Mises in his magnum opus of same name, Human Action. This concept is important for most Austrian Litterateur and will be crucial for the understanding of the market process; especially the entrepreneur.
Ludvig von Mises defines human action as purposeful behavior. And he continues: Action is will put into operation and transformed into an agency, is aiming at ends and goals, is the ego’s meaningful response to stimuli and to the conditions of its environment, is a person’s conscious adjustment to the state of the universe that determines his life.[1],[2] The difference between action and Mises notion of human action is that the observer attributes a goal to the action. Human action is in other words different from reflexive behavior, such as vomiting from drinking too much alcohol. Human action is purposeful behavior; it is conscious behavior. If man suppresses reflexive behavior, then this is human action, as it is conscious and from our point purposeful. (Mises 1949)
The study of human action is named praxeology. The science of praxeology contains the results deduced from the fact that people have goals, which they seek to obtain by selected means. It is not the science of the psychological events which result in the action, but the human action itself.
An action is a choice which involves both taking and renunciation, one alternative is chosen before another.  In other words praxeology is the study of means and ends. No man is in a position to superimpose his own value judgment on others and tell another acting man what will remove his uneasiness or make him happy. This means that every end is as such rational[3] (Mises 1949)
Mises list three prerequisites for human action. First of all, acting man must be in a state of uneasiness, if he was in a state of full satisfaction he would have no incentive to change things. Furthermore acting man must be able to imagine a state of higher satisfaction; he must imagine that he can remove his uneasiness. The final and third condition for human action is causality, the expectation that purposeful behavior will remove the felt uneasiness (Mises 1949:14).
Even though the subject of human action and praxeology is in no way exhausted, this is enough to describe the Austrian understanding of the market process. Thus I will move on to the next stepping stone on our path, namely the understanding of knowledge and the use and discovery of it in the market process.

The Use of Knowledge in Society

My headline for this section is also the title of F.A. Hayek’s famous paper from 1945. According to Hayek, the main economic problem which society faces is that of the utilization of knowledge not given to anyone in its totality[4]. There of the title of his paper, and also that of my section.
Thus, the economic problem of society is not to find the best available use of means, given all relevant information, including a predefined set of preferences and knowledge of all the means and ends. If so, the problem would be purely one of logic, namely the well known result that the marginal rates of substitution between two commodities must be the same. (Hayek 1945)
Knowledge in reality only exists as dispersed bits of incomplete and frequently contradictory information which all the separate individuals possess.[5] This is especially true for what Hayek calls the knowledge of the particular circumstances of time and place.[6] This is what I will call local knowledge, and a concept which will turn out to be important for the Austrian understanding of the market and the entrepreneur. Hayek also identifies the other main type of knowledge, scientific knowledge. This is knowledge which may be put in the hands of an authority; here a body of experts could command all available information. This is however not a possibility for local knowledge. Local knowledge cannot by its definition be centralized. Most of this knowledge is tacit in nature. For example the knowledge of how to operate a machine, avoid downtime, make repairs on the repairs which have altered it from the originally drawings; this is knowledge which is hard to centralize. Another example is the tradesman who works as an arbitrageur by selling and buying over time or geographical distance, he can only do this because of his local knowledge. Yet another example of local knowledge is unrevealed preferences. Since these preferences is not acted upon they are unrevealed, and they are therefore hidden from all other than the person holding them. (Hayek 1945)
Solving the Hayekian Knowledge Problem
The Austrian theory of the market process in Hayek’s view aims at explaining how knowledge reaches those who need it. How the market solves this problem, and thereby coordinates knowledge between the market participants, can be shown by an imaginary example:
Let us start with considering a single commodity market in competitive equilibrium. Each participant knows the price and does not need to know more than this to trade without disappointment or regret. Now an external event happens that shifts the supply curve left. Market prices will rise and buyers will start economizing on this commodity. This happens without the need to know why the price rose. This is the achievement for the market, for it solves the knowledge problem by using disperse information without one single mind planning the process, and at the same time economizes on the information. This is what Hayek calls the marvel of the market.
I will now follow Kirzner (1992) and elaborate on how this price adjustment happens, and show that the Hayekian Knowledge problem in fact consist of two knowledge problems, which both arises because of dispersed knowledge, but results in two different errors, to be solved in two different ways.
Knowledge problem A comes to existence when a seller is overly optimistic, and offers to sell at a price above what the buyers want to buy at. This situation is possible since the seller does not know what other market participants know about them self; their reservation price. So because of this disperse knowledge the market may fail to clear.
This error is however self-revealing. The seller knows there is a problem since his offer did not get accepted. Hayek explains that the relevant knowledge which he (an individual) must possess in order that equilibrium may prevail is the knowledge which he is bound to acquire in view of the position in which he originally is, and the plans which he then makes.[7] So knowledge problem A is so to say, self-correcting.
Knowledge problem B is the other side of the story. To describe this I will use an imaginary construct of two markets completely separated by an invisible wall. In each of these markets Knowledge Problem A has been solved and two different market clearing prices exist[8]. These two prices mean that someone in one of the markets has overlooked the possibility to buy the commodity cheaper in the other market. Also, other participants have refrained from buying in the high priced market, since they had a reservation price below the price the product was offered at, even though they could have bought it in the lower priced market. And in the lower priced market, some sellers have refrained from selling at the low price, but they would have sold in the high priced market. Here the market participants are not overly optimistic, but simply unaware of the price they might be able to obtain or buy at. They act as they were overly pessimistic about the prices. (Kirzner 1992)
Knowledge problem B is not self revealing; it does not lead to an unrealized plan, but to failure to obtain potential gains, as they do not perceive them. This problem is not self-correcting, and both of these problems of course have to be solved before a market clearing price will arise.  How will the market overcome this problem, how will people learn about others, what they do not know, they do not know?
The answer is that this problem creates an incentive for its solution by discovery in the activity of the profit alert entrepreneurs.[9] The knowledge of this profit opportunity first has to be discovered by an entrepreneur. The entrepreneur has to realize that the wall is invisible, and he can trade in both markets. How this is done will be explored in more detail later, but for now I will go on to identifying the entrepreneur in depth, before exploring his role in the market process.

The Entrepreneur

Now I will use our description of human action to introduce the entrepreneur, so I later in detail can establish his role in the market process. The entrepreneurs’ behavior and action is best described by the Misesian concept of human action. This is opposed to the classical understanding of human behavior; here the individual is allocating his scarce means towards his given ends. This is according to Kirzner (1973) best described by the discussion of Lionel Robbins (1932.) Here the individual is faced with the problem of how to allocate his resources, so he will reach as many as his ends as possible. He is economizing his resources to obtain certain ends. Mises human action on the other hand involves action to remove uneasiness.  It is not merely a reflection of the manipulation of given means to correspond faithfully with the hierarchy of given ends, but also the very perception of the ends-mean framework.[10] To put it differently, the agent in Austrian market theory does not only economize on the given means, he can also identify which means are available and which ends he should strive for by using his alertness and drive. Austrian economics thus have a broader view of individual behavior and actions. The ends-mean framework there is prevalent can thus be explained in the Austrian market process theory as a result of human action (Kirzner 1973.)
Above it was mentioned that the individual identifies these ends and means by being alert. This requires some elaboration as to what alertness is. Alertness to possibly new worthwhile goals and to possibly newly available resources is what Kirzner calls the entrepreneurial element in human decision making.[11] He elaborates further on alertness in the book: Discovery and the Capitalist Process (Kirzner 1985). Alertness must, importantly, embrace the awareness of the ways the human agent can, by imaginative, bold laps of faith, and determination, in fact create the future for which his present acts are designed.[12] It is this element which explains the creativity and innovative part of the human. Whereas the Robbinsian economizer is rather passive and mechanic, as he does not seek out new means, or becomes aware of new and better ends, the Austrian entrepreneur is creative and active.
The Pure Entrepreneur
Now I will characterize the pure entrepreneur, whose role only exists because of his alertness to not previously seized opportunities. He might not exist, but nevertheless will this help us in characterizing the role of the entrepreneur in the market process. This is no different than when we talk about the consumer, the landowner, the laborer or the capitalist. But we have to keep in mind, that the entrepreneur is more an element inherent in every human actor, than a specific person (Mises 1949)
The entrepreneur will only exist in a world of imperfect knowledge; he is a decision maker whose sole role is to be alert to hitherto unnoticed profit opportunities. To create this pure entrepreneur we have to envisage a decision maker, who starts out with no means whatsoever. This decision maker, this entrepreneur, would not exist was it not for information asymmetry, since he would have nothing to do without any means. His role is solely to be alert to profit opportunities. In this way he identifies for example a seller, who sells for prices too low. He could rent the resources for this product and use them in the production of another product, he could rent another resource he has knowledge of and add it to the production, or he could simply buy the product and sell it for a profit to those who will pay the higher price (Kirzner 1973.) He is bridging the knowledge gap by using his alertness to profit opportunities.
By the use of this pure entrepreneur, the economic agents can be divided into entrepreneurs and economizers. The economizer optimizes by taking the ends-means framework for given, they are passive price takers. The entrepreneurs are the ones who are causing changes in prices, quantities and qualities. Thus in this world with imperfect knowledge changes cannot be explained without the entrepreneur (Kirzner 1973.)
The pure entrepreneur can be hard to identify. An example of an almost pure entrepreneur could be the arbitrage hunter, who for example knows that the price of meat is higher in Latvia than in Denmark and trades thereafter.  But by making a single simplifying (though unrealistic) assumption, the producer can be identified as an entrepreneur. The producer can be seen as a resource owner, who contributes resources for the conversion of inputs to products. This resource owner could contribute with his ability to run a factory effectively, or the ability to calculate the optimal input and output, or simply just the capital. But if we assume that production is instantaneous and he hires all resources, he can be seen as a pure entrepreneur. The producer-entrepreneur realizes an opportunity in front of him by the help of his alertness and hires the resources and sells a product on a market. He identifies a lack of coordination in the market, he either sees resources used to produce products less needed than another product, or he may see products been produced with very costly resources. Either way he identifies this opportunity and improves the coordination of the market. To do this he does not need anything else than his alertness.[13] (Kirzner 1973.)
But production is not instantaneously, it takes time. From the above discussion it can be seen that the producer actually takes two functions, that of the entrepreneur and that of the resource owner. The resource owner is the pure Robbinsian optimizer and the entrepreneur is alert and solves a coordination problem. It gives us a very clear way of understanding the difference between an entrepreneur and a Robbinsian optimizer. The optimizer allocates given resources between ends in the production, the better he is at this the higher he is paid; he is a resource owner and is paid hereafter. The entrepreneur investigates which resources and which products should be produced. And the entrepreneur is paid a profit. As will be explained below, entrepreneurship is not to be seen as a factor of production (Kirzner 1973.)
Entrepreneurial profit, alertness and knowledge
Pure entrepreneurial profit is the difference between the two sets of prices[14] which the entrepreneur buys and sells at. This is the reward for his alertness by which he discovers the lack of coordination in the market. This is obtained without giving anything back. The entrepreneur is not exchanging something he values less for something he values more; he does not make an investment nor is he in any way a resource owner. Pure entrepreneurial profit is pure arbitrage, even though this requires an investment. The profit after interest is paid on the investment is still arbitrage. Thus by involving capitalists who own resources and are willing to lend these out for a fee (interest or wage), entrepreneurship over time becomes possible. The entrepreneur may also own resources himself, however there will still be an entrepreneurial profit part and a pay for use of the resources (Kirzner 1973.) This feature of the Austrian market process is no distinctive landmark of the Austrian School, since it is well established among most accounting, finance and management theories. However it, as Kirzner notes, emerges with exceptional clarity within this framework.[15],[16]
Alertness is not to be mistaken for superior command over information, as this is easily a thing which most academics or experts have. These will be paid as a factor of the production and is just another resource owner. However it is still the lack of coordination in market knowledge, which allows entrepreneurial profit and behavior. If all economic agents knew everything, then there would be no need for the entrepreneur, it would be a state without uncertainty. So we need ignorance for this. But we live in a world of ignorance because much of our knowledge is the previous mentioned local knowledge. Alertness must not be seen as knowledge about market data, but knowledge of where to find market data[17]. It is alertness to information in whatever form the entrepreneur may encounter or seek it (Kirzner 1973.)

Disequilibrium Analysis

In the above section about the entrepreneur it was mentioned that in a world with imperfect knowledge, it will not be possible to explain changes without the entrepreneur. I will, before explaining how the entrepreneur fits into disequilibrium analysis, discuss the Austrian understanding of equilibrium analysis, and what the proper use of it is.
The Evenly Rotating Economy
To quote Mises; “Action ultimately aims at bringing about a state of affairs in which there is no longer any action, whether because of all uneasiness has been removed or because any further removal of felt uneasiness is out of the question”[18] This sums up the Austrian take on the equilibrium concept, or as Mises calls it the final state of rest.[19] This is an imaginary construct which will never occur, however it is still important since it is the ultimate goal of acting man. Before this stage of the economy is realized, disturbing factors will derail the economy from its path. The reason for this is the passing of time, as the factors which affect the economy do not occur at the same time. In this final state of rest, or equilibrium as most economists know it, the final price is given not by historical prices, but by the conditions for it to emerge. (Mises 1949)
The final state of rest is as such just the eternal goal of the economy, a goal which will never be realized. But as a tool for economic analysis Mises uses the concept of the evenly rotating economy, in which changes in market data and time is removed. In this economy prices have reached the final prices, as defined by the final state of rest, and there is perfect price stability. Quantities and production stages remain the same and the same transactions are done over and over. It is not static but revolves evenly round a fixed center, it rotates evenly[20]. This imaginary construct can then be used to contrast different changes in market data (Mises 1949.) Austrian uses equilibrium as a foil, it is nothing more than a way to allow economist to think in a simple and clear way, by introducing an isolated factor and analyzing the effect of this keeping all other things equal (Boettke 1997.)
The Equilibrating Entrepreneur
In the evenly rotating economy there is no entrepreneurs, there is only automated and mechanical action, so we will have a world only with Robbinsian optimizers, who acts within a given ends-means framework. Since everyone knows everything in this evenly rotating economy there is no need for the entrepreneur (Kirzner 1973.) This final state and the evenly rotating economy are not our main interest, the interesting part is how the decisions of the individual market participants in the market interacts to generate the market forces which compel changes in prices, in outputs and in methods of production and allocation of resources.[21]
This is what is meant when the Austrian talks about disequilibrium theory. They are not interested in the criteria for equilibrium since it well never occur; equilibrium is a tool for analysis. How the market moves outside equilibrium and which institutions brings it towards equilibrium, is the subject economists wishes to investigate, when studying economics in an Austrian framework (Yeager 1997.)
The state of disequilibrium is characterized by ignorance and unawareness of some of all the possible exchange opportunities. There is room for improvement and a higher degree of market coordination. If the world was made up of Robbinsian optimizers then we would get nowhere, since everyone would assume that the same ends and means which was available yesterday also will be available tomorrow (Kirzner 1973.)
In the section on the use of knowledge in our society I went through how the market solves the main economic problem in the eyes of Hayek, namely the Hayekian knowledge problem. The entrepreneur plays a very important role in how the market solves this problem; he solves the before mentioned knowledge problem B. Knowledge problem B was not self revealing; it lead to failure to obtain potential gains. The entrepreneur realizes this because he is alert to profit opportunities.  He sees that a buyer is willing to pay, say DKK 100 for a service, but every other market participants thinks he is only willing to pay DKK 80. Therefore nobody is offering this service, since resources can be used better for other ends. The entrepreneur discovers this opportunity and takes action (Kirzner 1992.)
The entrepreneur is an essential part of the market process in Austrian economics. He is the force which brings the market towards equilibrium.[22] He brings change, which corrects the existing patterns of mistakes. The entrepreneur and the market process are inseparable.

A Critique of Equilibrium analysis

Most Austrians do not criticize the concept of equilibrium analysis; rather they criticize what they see as the misuse of this tool. We have already explained how Austrian economists use equilibrium as a tool for analysis, now we will see how the equilibrium concept is used in other schools of economics.
Equilibrium analysis is properly best known through Walras’s Law. Here Adam Smith’s invisible hand is proven to exist under some very strict conditions.[23] It’s the existence of this equilibrium, its stability and pareto optimality, which the neoclassical school of thought is mainly concerned with. (Boettke & Prychitko 1998).
Equilibrium analysis is used differently across various other schools of economic thoughts.  Boettke (1997) identifies three uses of equilibrium theory. Keynesian have often used it as an indictment, as a benchmark to measure the real world and any suggested changes to it. Equilibrium and perfect competition becomes a static ideal, and if the real world does not live up to this ideal we have an example of market failure. The Chicago School on the other hand uses equilibrium as a description of reality, here markets act as if they were in competitive equilibrium (Boettke 1997.) The Chicago school further uses equilibrium as an instrument for predictions. In Chicago style empirical analysis, the assumption of markets in equilibrium is used as a maintained hypothesis. (Sautet 2000) The Chicago school thus has an “equilibrium always” view of the market. The problem then becomes that the Chicago school have no way of explaining how markets achieve equilibrium. The Keynesians on the other hand does not see the coordinative power markets may have under imperfect information and ignorance (Boettke 1997.) In the Austrian School, departures from equilibrium are a natural part of the market system. They are caused by human imperfection and are not a failure of the market, as seen by Keynesians. Even though these two neoclassical schools are concerned with convergence and stability of equilibrium, the adjustments in the market still becomes footnotes in the literature and not the main economic problem under investigation.
In a world where everyone is a price taker, the question of how the market moves towards equilibrium, are unanswered, since there in these equilibrium models is no agent of change. What comes closest is the mysterious Walrasian auctioneer (Boettke & Prychitko 1998.) The entrepreneur or his equal is absent.
Mises (1949) put the critic in the following way: The image (the evenly rotating economy or equilibrium) is merely a tool for our thinking. It is not a description of a possible or realizable state of affairs. It is even out of the question to carry the imaginary construct of the evenly rotating economy to its ultimate logical consequence. For it is impossible to eliminate the entrepreneur from the picture of a market economy. The various complementary factors of production cannot come together spontaneously.[24] Thus the Austrian critique of equilibrium analysis can be summed up as a critique of the use of equilibrium analysis in any way, which indicates that it is a description of the real world, or an attainable state which can be used for benchmarking.
As mentioned, the Austrian critique is about the misuse of the equilibrium concept. For some potential areas where the Austrian school could use equilibrium theory see Yeager (1997), Yeager (1999) and Boettke & Prychitko (1998). I have not mentioned every aspect of the Austrian critique of equilibrium analysis, but only those relevant for TCT. For other aspects see for example Hayek (1946), Boettke (1997), Mises (1949:249-252), and Kirzner (1973:26-29). Now I will present the market theory problem as in Sautet (2000).

The Market Theory Problem

The MTP is the inconsistency involved in trying to answer questions that would not exist in an equilibrium-always world,[25] by using a theory build upon an equilibrium theory framework. The MTP exist when a theory uses the equilibrium concept as a description of reality, an instrument or as an indictment, and at the same time tries to investigate problems, which only exist in disequilibrium. Frederic Sautet (2000) identifies four concepts that represent the core of Austrian market theory and shows, how the absence of these is the distinguishing mark of the MTP.
Uncertainty: The Austrian understands uncertainty as Knight (1921) understood it, and genuine change can therefore take place in this open ended universe. This is not stated explicit in the above, but lies implicit in the concepts of human action and alertness. Since the entrepreneur can create the future, it must necessarily be characterized by genuine uncertainty, because of genuine ignorance of the future. This means it cannot be modeled by probabilities as in the neoclassical modeling of uncertainty. The MTP is thus characterized by the absence of genuine uncertainty and a closed ended view of the universe. (Sautet 2000)
Information and knowledge:  Hayek identified the economic problem as that of the discovery of dispersed information and not just the allocation of known resources. This is in contrast to the bookshelf approach[26] where there is an optimum level of ignorance, a level, which can be found by a simple cost benefit analysis within a given information framework. So the MTP is characterized by the absence of a need for knowledge to be discovered, and treatment of information as a commodity. (Sautet 2000)
Disequilibrium analysis: This should not need much more elaboration and should be clear from the previous critique of equilibrium analysis. Disequilibrium analysis is the keystone of the modern Austrian economic explanation of the market[27]. Thus the MTP is characterized by absence of disequilibrium analysis. (Sautet 2000)
Entrepreneurship: In the imaginary construction of the evenly rotating economy there is no room left for entrepreneurial activity, because this construction eliminates any change of data that could affect prices.[28] Thus the MTP is characterized by the absence of entrepreneurship.

Final Remarks

I have in this article given a walkthrough of the Austrian School of Economics theory of the market process. By presenting the concept of human action, the ground work for the entrepreneur was laid. The entrepreneur is active and discovers new knowledge by being alert to profit opportunities. Thereby he is an equilibrating force in the market and helps in solving the Hayekian knowledge problem. Specifically he solves the Hayekian knowledge problem B, which is not self correcting as knowledge problem A is.
Thus, the entrepreneur is the equilibrating force in the market. The Austrians view the market as a process, which cannot be explained by investigating equilibrium and the conditions for it to exist. The interesting part is how the decisions of the individual market participants in the market interact to generate the market forces which compel changes in prices, in outputs and in methods of production and allocation of resources.[29]
Since most market theory deals with a disequilibrium concept, I am convinced that existing theories in this field would benefit from contributions from the Austrian School since it, as opposed to the neoclassical schools, has its focus on disequilibrium. This is especially true for theories of the firm, which necessarily deals with a disequilibrium concept, the firm.
I’m happy you took the time to read this, and hope you had just as good a time reading it, as I had writing it. If you want to read the paper in its totality with the critique of Transaction Cost Theory, it’s available here.

[16] This view of entrepreneurship is very close to that of Frank H. Knight. Entrepreneurship represents for him judgment under true uncertainty that cannot be assessed in terms of its marginal product and which cannot, accordingly be paid a wage. As we will see later, the absence of Knightian uncertainty will be a characteristic of the MTP. (Knight 1921:310-312)

[22] This is the exact opposite of the widespread understanding of the entrepreneur advanced by Joseph Schumpeter. Here the entrepreneur is a disequilibrating force which brings the market away from equilibrium by creative destruction. The entrepreneur does this by entrepreneurial innovation and he generates new opportunities (Schumpeter 1934.) Kirzners entrepreneur brings the market towards equilibrium by realizing that existing opportunities exist and increases coordination by seizing these opportunities in the search for profit.
[23] Walras’s law shows that there exist a price vector which gives zero aggregate demand and therefore the market clearers. This requires zero transaction costs, perfect information, large numbers of buyers and suppliers, and thereby price taker behavior. If these conditions are met, we will have a competitive equilibrium under which the two welfare theorems hold (Boettke & Prychitko 1998.) These conditions are normally known as the perfect competition conditions.

  1. High Jesper loved the work! I noticed that you are part of the Aarhus University. An Aarhus Libertarian society has opened not long ago. We have meetings every Wednesday, it would be great to have you come along sometime! You can find our new facebook page at http://www.facebook/ The page has only a few people, but the facebook group that we used to meet on has about 50 people. On average around 7-8 people attend the meetings. Hope to hear from you!
