Many, including some Nobel Prize winners, maintain that crises are by their very nature unpredictable. At the same time, others -- aided by engineers, physicists, ecologists and computer scientists -- are developing ways to detect and quantify systemic risks, including measures that regulators could use to identify imbalances or vulnerabilities that might result in a crisis. ...
The challenge for economists is to find those indicators that can provide regulators with reliable early warnings of trouble. ...
Work is racing ahead. In the U.S., the newly formed Office of Financial Research has published various papers on topics such as stress tests and data gaps -- including one that reviews a list of some 31 proposed systemic-risk measures. The economists John Geanakoplos and Lasse Pedersen have offered specific proposals on measuring the extent to which markets are driven by leverage, which tends to make the whole system more fragile.
