Of course we’ve discussed this before (here, and I’m sure other places).
I think one would do just fine (great, actually) by simply working through the typical beginner texts up through the advanced of say, the contents of the Mises Store.
But I would say there would be value to be had (that would largely be missed) in an introductory microeconomics textbook. Lessons for the Young Economist does a great job of giving a comprehensive overview of the whole of economic science (for the beginner, anyway), and of course includes some of this information. But I think the details included in a typical micro textbook would be largely helpful.
There are of course classics in the Austrian tradition that will cover this (e.g. Principles of Economics, MES…in fact there’s even a course by Rothbard “Introduction to Microeconomics” and a paper “An Austrian Foundation for Microeconomic Principles” [PDF]), but I get the feeling the format and arrangement of a typical modern day textbook would be useful.
That being said, there is actually a course in the Mises Academy coming up…Austrian Microeconomics. I’d be interested to see the syllabus.
