Guest Post: Princeton Economist and Computer Scientists Show that Derivatives Are Inherently Vulnerable to Fraud

...the main default risk model for credit default swaps -- the ``Gaussian copula function'' -- was inherently flawed. Now, Princeton University economists and computer scientists have demonstrated that financial derivatives are also inherently vulnerable to fraudulent pricing. PhysOrg summarizes Princeton's findings: ...sellers of these investments could purposefully include pieces of bad risk that no buyer could detect even with the most powerful computers... the problem arises from asymmetric information between buyers and sellers, and goes against conventional wisdom in economic theory, which holds that derivatives reduce the negative effects of such unequal information.
