If anyone is interested in hearing more from Ronald Coase (and you should be), he was on the excellent Econtalk Podcast earlier in the year: http://www.econtalk.org/archives/_featuring/ronald_coase/

The topic is "Coase on Externalities, the Firm, and the State of Economics", well worth the time if this topic interests you.
