The New York Times cited a paper co-written by Dr. Joseph Mason, associate professor of finance, in its February 18, 2007, edition. The paper notes that insufficient transparency in the market of collateralized debt obligations, significant changes in asset composition and a credit rating industry ill-equipped to assess market risk and operational weaknesses could result in a broad financial decline. Another story that noted the paper was published on the Yahoo! Finance site on February 20. Dr. Mason also commented on mortgage news on CNBC's Street Signs program on February 20.
