This is a five minute YouTube video, dating from June 2008 and featuring Dan Ariely talking about how his experience as patient suffering 70 percent burns led him to explore pain management and question how supposed rational choices can be irrational. It looks at how cognitive psychology can effect choices and behaviour, especially in the sphere of economics. The video is presented as part of the Predictably Irrational website, that promotes Ariely's book of the same title.

A lecture by Murray Rothbard, delivered in the days following the collapse of the Soviet sphere of influence (just under 50 minutes long). A former dean of the Austrian School of Economics, Rothbard is a supporter of laissez-faire capitalism. This video could be a good starting point for a debate on different economic models.
