There is, quite simply, a lot here to comment on, but I will limit myself to these remarks:
(1) Kirzner sees Menger’s immediate successors as developing a “static” form of subjectivism. As Lachmann would later say, the “subjectivist” revolution was not complete until subjectivism was applied to expectations. Kirzner sees “dynamic” subjectivism as the more advanced from that replaced the early Austrian school (1871-1930s).
(2) Kirzner notes that by the 1940s virtually everyone thought that the Austrian tradition was dead. Indeed, Kirzner says it was an embarrassment to admit he was studying under Mises in the 1940s (from 10.20).
(3) Eugen von Böhm-Bawerk and Friedrich von Wieser were not students of Carl Menger (1840–1921), but colleagues. Kirzner notes the conflict between the early Austrian school and the German Historical School, over economic method (the “Methodenstreit” or “debate over methods”). The term “Austrian school” was first coined by members of the German Historical School as a derogatory term for their enemies in Vienna.
(4) A serious shortcoming of this talk is its failure to examine the progressive liberal and even Fabian socialist sympathies amongst some of the early Austrian economics, such as Eugen von Philippovich, Friedrich von Wieser, the early Hayek, and Richard von Strigl. For that, see here:“When I arrived at the London School of Economics in the spring of 1933, all important economists there were Hayekians. At the end of the decade Hayek was a rather lonely figure, even though he remained editor of Economica throughout the war.” (Lachmann 1994: 160).That is to say, it was only at the LSE that “all important economists there were Hayekians.” That is quite a big difference.
(6) The merits of subjectivism have their limits, however. For example, just because economic “value” might be defined as the subjective pleasure, utility or satisfaction we derive from commodities, this does not mean prices are therefore all subjective. It is necessary to distinguish “price theory” from “value theory.” The price of a commodity and its value are two different things. It is clear that the normal price of many newly produced commodities is related to the cost of production. For what business could offer a long run, standard price for its commodities below its costs of production? There is no contradiction in also saying that whatever economic “value” (that is, utility or satisfaction) that a commodity has to any individual human being is subjective.
(7) From 52.00, Kirzner makes a very important point: he cites the view of Fritz Machlup (1902–1983) that everything that was important in the Austrian school of the 1920s had been successfully absorbed into the neoclassical mainstream. Kirzner agrees with this. Thus Machlup did not even find it necessary to identify himself as an “Austrian,” because he saw the Austrian tradition as having been successfully absorbed. When Machlup was asked to list the most important tenets of the Austrian school, he produced this list:(1) methodological individualism;Kirzner argues that all of these are part of the neoclassical mainstream now.
(2) methodological subjectivism;
(4) opportunity cost;
(5) time structure of production;
(6) dominance of utility.
The only two features that Kirzner thinks are unique in modern, post-1950 Austrian economics not taken into account by the mainstream are (1) that markets are processes of learning and discovery, and (2) that choice is taken in the context of radical uncertainty.
