NYU's Austrian Economics guru Mario Rizzo has this to say. Here is the entry Mario wrote for the New Palgrave.
I met Mario once when I was attending the FEE Austrian seminar, a real scholar and gentleman. It was also at FEE where I met Israel Kirzner for the first time.
Speaking about Austrian Economics, my teacher Richard Wagner would have a new book on the subject due out in early next year entitled, "Mind, Society and Human Action."
