Randall G. Holcombe has just pubished a 144 page book "Advanced Introduction to the Austrian School of Economics".
Dr. Holcome asserts that readers should have a basic knowledge of economics but might be unclear about what makes the "Austrian School" different.
As a result of recent history, "more people have heard of the Austrian school, even though they may not be familiar with its most important ideas." And this served as motivation for the book.
