As I noted here, Professor Hoppe recently delivered the speech “State or Private Law Society?” in April 2011 at the 2nd Austrian School Conference, Mises Institute Brasil, in Porto Alegre.
His second talk delivered at the same conference, “Economic Crises: How to Cause Them and How to Make Them Worse by ‘Curing’ Them,” is now also available. [Youtube videos of the talk may be found here.]
