The finance-desk math wizards who created the securities behind the market meltdown are now betting they can think their way out of the mess, the Wall Street Journal reports, working to design new systems for pricing bad assets fairly so governments can buy them off of banks’ balance sheets. “Airplanes fail, too,” one such whiz says. “That doesn’t mean you don’t fix them.”
The models most banks use are “superficial,” as one engineer says, and “often spit out prices that don’t capture the underlying value of the assets.” Firms are devising pricing strategies that dig deeper using a variety of data, and by examining slices of derivatives with various maturities. Others are creating real-time loan-performance evaluations, making it easier to value institutions holding these securities.
