"MIT World": Merton Lecture on Derivatives

There will be a time “beyond crisis,” asserts Robert C. Merton (in this video lecture). "He delves into the dense science of derivatives -- a field he has fundamentally shaped -- to explain how the vast global economic collapse has come about, and how financial innovations at the heart of the collapse could also be tools for reconstruction."

A whole range of "MIT World" videos are available to browse through here. There is one by Drazen Prelec on Neuroeconomics, one by Jonathan Gruber on Healthcare, and one by Bill Gates on Innovation.
