Stiglitz is one of the few (liberal) economists who is not suffering from a massive bought of cognitive dissonance owing to the GFC. This hour long interview with Joseph Stiglitz is well worth watching. Don’t have an hour? Then watch the first fifteen minutes.
You might be interested in Mason Gaffney’s recent book, “After the Crash: Designing a Depression-Free Economy.” You can read a related interview at http://www.masongaffney.org/
Also on that website, I encourage you to read “The Great Crash of 2008” and “How to Thaw Credit Forever.”
