"Normal science" means research firmly based upon one or more past scientific achievements, achievements that some particular scientific community acknowledges for a time as supplying the foundation for its further practice.
-Thomas Kuhn, The Structure of Scientific Revolutions
Comparisons between the Austrians and the New Classicals are nothing new. The New Classicals often thought of themselves as continuing the Austrian project of theorizing by embracing equilibrium-theories of the business cycle inspired by Hayek’s work in the twenties. Alex Tabarrok wrote that has argued that Robert Lucas is the greatest Austrian economist of the 20th century. The controversy now continues.
In his blog, “Noahopinion”, Noah Smith argues that the New Classicals drank the Austrians' milkshake. They took what was worthwhile within the Austrian research program, and advanced it further than any Austrian has been able to. The problem with Smith’s argument is that even though there is much that the Austrians and New Classicals agree on, the disagreements between the two are far too many for the New Classicals and Austrians to be continued a single strand of thought. Those differences are brought to light when we consider that the New Classicals, who could very much be considered heirs to the techniques of the Market Socialist Oskar Lange, cannot make sense of the Austrian critique of socialism within their way of doing economics.
The most major difference between the paradigm of Mises and Hayek, and that of Prescott and Lucas is not what they think about issues that Smith brings up like mathematics or disagreements about the nature of the business cycle. The most important differences, which informs the two paradigms’ very outlook is that that the two are contradictory in their answers to what economics is largely about. Whereas the Austrians focus on questions of how the order of the market order emerges, the New Classical assumes that order in their difference equations.
The most succinct expression of the outlook of the Austrian school comes from Hayek in The Fatal Conceit when he wrote that “The most curious task of economics is to demonstrate to men just how little they really know about what they imagine they can design” (Hayek 1988, 76). On the other hand, in “Methods and Problems in Business Cycle Theory”, Lucas asserted: “One of the functions of theoretical economies is to provide fully articulated, artificial economic systems that can serve as laboratories in which policies that would be prohibitively expensive to experiment with in actual economies can be tested out at much lower cost.” Hayek’s vision of economics is to warn against the very intentions of Lucas: that no human being can have sufficient knowledge to design an economic order, it can only emerge from market process. There is an extreme tension here which betrays the radical difference between the two paradigms, and it is all made manifest by thinking about the Socialist Calculation Debate.
We must keep in mind that the Austrian economists' crowning achievement to this day is their proof of the impossibility of socialism during the Socialist Calculation Debate. Within that debate, Mises and Hayek argued that the socialist vision that an economic order could be created by the planning of one or many human minds was impossible, and that the only way for an economic order to come about was through the use of prices. Their legacy is in part built upon their work against socialist in the ‘20s, ‘30s, and 40’s. Anyone who wants to lay claim to improving upon the Mises-Hayek paradigm has to be able to capture the lessons of the Mises’ seminal article “Economic Calculation in the Socialist Commonwealth.” The New Classicals, with their emphasis on the important of analgoue economies. simply cannot do that.
Even though Lucas emphasizes that we must be mindful of the difference between real and toy economies, the notion that economists could even sufficiently approximate the nature of the economy in theory would be absurd to both Mises and Hayek. Neither Austrian would have anything to do with statements like:
On this general view of the nature of economic theory then, a ‘theory’ is not a collection of assertions about the behavior of the actual economy but rather an explicit set of instructions for building a parallel or analogue system - a mechanical imitation economy. A ‘good’ model from, this point of view, will not exactly be more ‘real’ than a poor one, but will provide better imitations (Lucas, 1980).
If Mises and Hayek were to read that quote, I bet they would be reminded of Oskar Lange’s argument that socialism could work because the central planning board could serve the function of the Walrasian auctioneer, and direct the use of factors of production with knowledge of their marginal costs. The Austrians disagreed, and Mises shot the first shot in 1920 with “Economic Calculation in the Socialist Commonwealth.”
They argued that Lange greatly overestimated the potential of the human mind to comprehend the economic order, so does Lucas, and that overestimation separates his work work from the tradition of the Austrians because the Austrian tradition constantly emphasized that the market order was simply too complex to be adequately summed up in a system of stochastically disturbed difference equations.
So much of Austrian scholarship has been inspired by the problems of the emergence of a social order from decentralized cooperation which the Lucas-Prescott paradigm cannot capture. The Mises-Hayek paradigm is concerned first and foremost with the study of spontaneous order, and with the the emergent properties caused by the connectedness between market participants. (Arnold Kling, in his own response to Noah Smith got at the importance of the issue of connectedness when he wrote: The bottom line: Austrian economics ought to resemble PSST, not New Classical.) The New Classical toy economy cannot capture those aspects of the market order, and so role of spontaneous order in the hat the Austrian School has to do with complexity, and the interconnectedness of human beings within society is manifest in Human Action when Ludwig von Mises wrote:
The (socialist) director does not simply have to deal with coal as such, but with thousands and thousands of pits already in operation in various places, and with the possibilities for digging new pits, with the various methods of mining in each of them, with the different qualities of coal in various deposits, with the various methods for utilizing the coal for the production of power, and a great number of derivatives (Mises 1998, 695).
The New Classical paradigm cannot even sense of problems of connectedness because of their adherence to general equilibrium as the way of doing economics.
The very nature of how general-equilibrium theory is constructed glosses over the facts that there are particular paths of interaction within a market order. Jason Potts, a fellow heterodox to the Austrians, addressed this concern in The New Evolutionary Microeconomics:
The quality of space being integral derives from the assumption that a single (mathematical) operation links any point in economic space with any other point. Interactions, knowledge, and structure specific connections between points in space and therefore the very existence of these concepts is excluded by the assumption that all points relate, a priori, to all other points directly; that is, with a single mathematical operation (Potts 2000, 17).
Robert Lucas had profuse praise for Gerard Debreu’s Theory of Value, a work which sought to prove that a Pareto optimal distribution of a set resources could be created consistent with profit and utility maximization? On the back of the book Lucas praises The Thgeory of Value as an “immortal classic in twentieth-century economics.” The central role which the New Classicals think that such equilibrium frameworks, especially competitive equilibrium, played in the normal science of economics is a major point of divergence between them and the Austrians.
Competitive equilibrium assumes away the questions of conceitedness which the Austrians are most concerned with, and have given rise to Kirzner’s writings about the entrepreneur, and even Hayek’s ideas about the business cycle. If we are to think about an intellectual’s theorizing as a means of him satisfying the uneasiness certain problems weigh on his mind, we could say that competitive equilibrium assumes away the problems which the Austrians are most troubled by. Mises, for instance, critiqued the use of mathematics in economics for looking over all the questions which should make economists wonder about the possibility of a socialist economy:
The result is that from the writings of the mathematical economists the imaginary construction of a socialist commonwealth emerges as a realizable system of cooperation under the division of labor, as a fully-fledged alternative to the economic system based on private control of the means of production. The director of the socialist community will be in a position to allocate the various factors of production in a rational way, i.e., on the grounds of calculation (Mises 1998, 698).
For Mises, competitive-equilibrium frameworks glossed over the problems of coordination and price emergence which doomed the hopes of would-be socialists, and as a result that framework did not capture enough of the economy’s essence to be that useful to the study of that phenomenon.
Lucas’ assertion that economics could create toy economies sufficiently realistic to provide a preliminary testing ground for regulations is of the type which Mises is arguing against here. Even though Prescott, Lucas, and other New Classicals would have recourse to other arguments for why a socialist director would not be able to construct an economic order from on high, they cannot make sense of Mises’ and Hayek’s theses about how cooperation conditioned by prices are able to conquer, to quote Keynes, the dark forces of time and ignorance everyone faces in economic life. As a result, the New Classicals could even be considered a decay, rather than a refinement, of the Austrian insights into the nature of the market order, and of society at large.
In the end, there is not a lot of room for the Austrian insights about human competition within a model of an analogue. By asserting that the New Classicals have adopted and advanced the Austrian research program, Noah Smith has Two features really make the paradigm of Mises and Hayek special: that the two look at purposeful action within the context of radical uncertainty, and the interconnectedness between human beings which results from such behavior. Whereas Prescott and Lucas theorize about a world of linearity and smoothness, Mises and Hayek theorized about a world of complexity and uncertainty.
So no, the Austrians and New Classicals are not one strand of through. Rather than the New Classicals drinking the Austrians milkshake, stealing their ideas while giving them no credit (in the comments: Noah Smith notes: “I would say someone else picked up a lot of their ideas, ran with them, and won, but didn't give the Austrians any credit... ;-)”), the New Classicals represent the fruition of the economic approach of the Market Socialists. Indeed, it wouldn’t be an understatement to say that Ludwig von Mises and Friedrich Hayek share more in common with John Maynard Keynes and Hyman Minsky than they do either Prescott or Lucas.

Roundtable: What is Democracy?
From On the Laws by Cicero, I.41:
Now every people (which is the kind of large assemblage I have described), every state (which is the organization of the people), every commonwealth (which, is, as I said, the concern of the people) needs to be ruled by some sort of deliberation in order to be long lived. That deliberative function, moreover must always be connected to the original cause which engendered the state; and it must also be either assigned to one person or to selected individuals or be taken up by the entire population. And so, when the control of everything is in the hands of one person, we call that one person a kind and that type of commonwealth a monarchy. When it is in the control of chosen men, then a state is said to be ruled by the will of the aristocracy. And that which everything is in the hands of the people is a “popular” state – that is what we call it. And of these three types any one, even though it may not be perfect or in my opinion the best possible, still is tolerable as long as it holds to the bond which first bound men together in the association of the commonwealth; and any one may be better than another.
This is a rather classical view deriving from Aristotle's taxonomy of different types of poleis within the Hellenistic world. The emphasis on who within the population deliberates on the functions on the government, though, is an attribute of democracy that any sound notion of it must capture. T
he notion that democracy is the deliberation about laws among the entire population has been emphasized by contemporary theorists like Amartya Sen. In his own work, Sen has argued that the reasons that there has never been no major famine in a modern democracy is this deliberative aspect of democracy. Since everyone can have a say in the deliberation of policies within a democracy, few within government cannot hide the facts behind famines for long and the outcry for famine-relief cannot be long kept quiet.
Another aspect of democracy is highlighted by Karl Popper in The Open Society and Its Enemies Vol I., pg. 124:
(W)e may distinguish two main types of government. The first consists of governments which we can get rid (sic) without bloodshed – for example, by way of general elections; that is to say, the social institutions provide means by which the rulers may be dismissed by the ruled, and the social traditions ensure that these institutions will not be easily destroyed by those who are in power. The second type consists of governments which the ruled cannot get rid of (sic) except by way of a successful revolution – that is to say, in most cases, not at all. I suggest the term “democracy” as a short-hand label for a government of the first type, and the term “tyranny” or “dictatorship” for the second. This, I believe, corresponds closely to traditional usage.
Popper's assertion that a democracy is a changable government brings to mind something that Edmund Burke said in Reflections on the Revolution in France: “A state without the means of some change is without the means of its conservation.”No doubt, the authoritarian style of the Bourbon kings and the centralization of political power in the halls of Versailles created a political climate in which change could only be achieved via bloodshed and the great tragedy that was the French Revolution.
Ludwig von Mises also emphasizes that a democracy is a government that can change as to best suit the will of the governed. From Liberalism, pg. 21:
Democracy is the form of political constitution which makes possible the adaptation of the government to the wishes of the governed without violent struggles. If in a democratic state the government is no longer being conducted as the majority of the population would have it, no civil war is necessary to put into office those who are willing to work to suit the majority. By means of elections and parliamentary arrangements, the change of government is executed smoothly and without friction, violence, or bloodshed.
When speaking about what democracy is, it is also important to keep in mind what democracy is not and Friedrich Hayek writes about this in The Constitution of Liberty, pg. 103:
Equality before the law leads to the demand that all men should also have the same share in making the law. This is the point where where the traditional liberalism and the democratic movement meet. Liberalism (in the European nineteenth-century meaning of the word, to which we shall adhere throughout this chapter) is concerned mainly with limiting the coercive powers of all government, whether democratic or not, whereas the dogmatic democrat knows only one limit – current majority opinion. The difference between the two ideals stands out most clearly if we name their opposites: for democracy it is authoritarian government; for liberalism it is totalitarianism. Neither of the two systems necessarily excludes the opposite of the other: a democracy may well wield totalitarian powers, and it is conceivable that an authoritarian government may act of liberal principles.
There can be both illiberal and liberal democracy. Of course, as both Popper and Mises have noted, the benefit to an illiberal democracy as opposed to, say, an illiberal monarchy is that an illiberal democracy can be changed if there are enough votes against it.
Finally, we have our last perspective in this roundtable from “Perpetual Peace: A Philosophical Sketch” by Immanuel Kant:
A republican constitution is founded upon three principles: firstly, the principle of freedom for all members of a society (as men); secondly, the principle of the dependence of everyone upon a single common legislation (as subjects); and thirdly, the principle of legal equality for everyone (as citizens). It is the only constitution that can be derived from the idea of original contract, upon which all rightful constitution of a people must be founded. Thus as far as right is concerned, republicanism is in itself the original basis of every kind of civil constitution, and it only remains to ask whether it is the only constitution which can lead to a perpetual peace.
While Kant does not describe here his notion of what “Democracy” is, but our modern notion of democracy is so close to his notion of republicanism, just as it is close to what the American founders like Madison thought of as republican government, that he mind as well be talking about modern democracy. That modern theorists like John Rawls have tried to create normative standards for democracy around notions like Kant's original contract is even more evidence that Kant speaks here of what we call “Democracy” today. Then again, we need to keep in mind Hayek's lesson that we cannot equivocate Liberalism and democracy.
This is a typical Kantian attempt at trying to understand something as well. Like Aristotle, I often think of Kant's philosophical style of taxonomic: he tries to augment our understanding of philosophical objects by immediately creating categories and systems of classification. Indeed, one of the reasons the Critique of Pure Reason can be so intimidating is just how many new words Kant creates in order to classify reason in its many functions.
However, I am greatly skeptical of the entire philosophical project of trying to deduce the nature of government via a priori constructions like the original contract. I think that Burke succinctly summarized all the errors of this rational constructivist approach when he wrote in his Reflections: “The science of constructing a commonwealth, or renovating it, or reforming it, is, like every other experimental science, not to be taught a priori.
