Tranching, CDS and Asset Prices : How Financial Innovation Can Cause Bubbles and Crashes
Fostel, Ana - 2011
We show how the timing of financial innovation might have contributed to the mortgage bubble and then to the crash of 2007-2009. We show why tranching and leverage first raised asset prices and why CDS lowered them afterwards. This may seem puzzling, since it implies that creating a derivative...

The financial origins of non-fundamental risk
Acharya, Sushant; Dogra, Keshav; Singh, Sanjay R. - 2022 - Last updated: January 14, 2022
