Brendan Moynihan - Financial Origami; How the Wall Street Model Broke (2011).pdf

An in-depth look at the failure of Wall Street's "proven" financial models
Origami is the Japanese art of folding paper into intricate and aesthetically attractive shapes. As such, it is the perfect metaphor for the Wall Street financial engineering model, which ultimately proved to be the underlying cause of the 2008 financial crisis.
In Financial Origami, Brendan Moynihan describes how the Wall Street business model evolved from a method to transfer risk into a method for manufacturing risk. Along the way, this timely book skillfully dissects financial engineering and addresses how it's often a mechanism to evade regulatory constraints, provide institutional investors with customized products, and, of course, generate revenue for financial engineers.

With the collapse of Lehman Brother the Wall Street business model effectively broke. But there are many lessons to be learned from what has transpired, and Financial Origami will show you what they are.
