I want to know the answer to the following question:
Several reports written by various agencies  concluded that which policy was not the primary cause of the financial crisis?
All the background I'm provided with is that "Although they concede that governmental policies had some role in causing the crisis, they contend that GSE loans performed better than loans securitized by private investment banks, and performed better than some loans originated by institutions that held loans in their own portfolios.". Is that enough to answer the question?
