The Austrian school was founded by Carl Menger in the 1870s and is distinguished by its subjective theory of value, its attention to time and the structure of capital, its account of markets as processes of discovery instead of states of equilibrium, and its deep skepticism about mathematical modeling and aggregate statistics.
Menger's Principles of Economics (1871) was one of three near-simultaneous statements of marginal utility, but the Austrian line diverged from the others almost immediately by refusing to treat economics as a matter of equilibrium conditions. Böhm-Bawerk developed the theory of capital and interest around time preference. Mises then made the tradition's most consequential argument in 1920: a socialist economy without market prices for capital goods cannot allocate them rationally, because it has no way to calculate. Hayek extended the point epistemically. Prices are not merely signals; they are the only mechanism by which the dispersed and largely tacit knowledge held by millions of people can be brought to bear on production at all.
The tradition splits on method. Mises held economics to be a deductive science of human action, praxeology, whose theorems are established a priori and cannot be refuted by statistics. Hayek moved away from that toward evolutionary and institutional argument. Kirzner's work on entrepreneurial alertness sits closer to conventional economics. Rothbard took the deductive line and combined it with natural-rights ethics into a political program Hayek never endorsed.
The Austrian critique of central planning is now broadly accepted, including by economists who reject everything else in the tradition, and Hayek's 1974 Nobel recognized exactly that. Its marginalization within academic economics follows mostly from the methodological objection to formal testing. A school that declines to state falsifiable predictions is hard to integrate into a discipline organized around them, and Austrians disagree among themselves about whether that is a principled stand or a self-inflicted wound.
