I dont know but . . .
I don't know the answer to your question, but there may not be an answer. The Austrians don't engage much in graphical analysis. I understand there to be a couple of reasons for this. Aggregate economic statistics tend to be based on some assumptions that Austrians find unacceptable.
First is the subjective theory of value. Because the Austrians see value as purely subjective and ordinal, they do not believe it can be derived numerically and graphed or otherwise manipulated as a statistic. Aggregate statistics typically rely on a labor theory of value which the Austrians reject.
Second is the artificial compartmentalization of microeconomics and macroeconomics. An AS curve may have such a narrow focus as to be unacceptable to an Austrian. But I don't know.
There may be more reasons. Or less! This is pretty far over my head since I have never had an econ course in my life. The good news is that means I am uncontaminated by Keynsian nonsense. The bad news is that I can't speak their language. Hahahaha!
