I have assembled below a set of links to various posts on my blog for debunking the theories of Austrian economics.
Please note that not all the posts actually debunk Austrian theories, as some are merely descriptive, and allow the reader to understand what the Austrians believe. Some examine the history of the school. A few posts are even constructive in that Post Keynesians and some Austrians can agree on certain points (such as the posts on Ludwig Lachmann).Read it at Social Democracy for the 21st Century
One important point I have always stressed is that the Austrian school itself is heterogeneous.
