Here. A very interesting post that links to another great post by LK on the subject. They tie Mises to the "soup kitchens caused the Depression" view, or more formally - that a variety of policy changes had major negative supply impacts.
While I'm on the subject of the longevity of Austrian Business Cycle Theory, I did not link to this post by Jonathan criticizing my claim in my recent Critical Review article that Hayek's BCT (although I'd throw in ABCT generally) was inconsequential for macro (after the 30s of course). Jonathan's argument doesn't really move me at all (in fact I cited some of the things that he mentions in the article), but it's worth looking at. I think he changes the question to "has any important macroeconomist ever cited Hayek or liked to read him", the answer to which is of course "yes", but not the question I'm interested in. The case that Hayek was essential to RBC is very weak. The connections are vague in the first place, they have nothing to do with the central features of Hayek's BCT, and none of the handful of what we consider foundational papers in that literature cite him or anyone having anything to do with his business cycle theory. It's true that Lucas cites him in another paper - not for his business cycle theory but for saying that a Walrasian general equilibrium view is important. Anyway, I could go on but there is really no case for this at all. But read Jonathan and see what you think.
Actually the best case for Hayek's influence on macro is that he helped move Keynes from the Treatise to the General Theory, but of course that has nothing to do with Hayek's own BCT.
