Professor Menachem Brenner is interviewed about his research on ambiguity in financial markets; Professor William Silber is quoted
Excerpt from The Wall Street Journal -- "Mr. Brenner, a professor at New York University’s Stern School of Business who helped develop the first volatility index, now is focused on what he believes will be an actionable gauge of the kind of fear now pervading the markets. 'The VIX is low because it doesn’t measure ambiguity. The uncertainty is much bigger than that,' Mr. Brenner said. 'I believe that’s what ambiguity is going to capture.'"
