In my 2010 book Crisis Economics, I defined financial crises not as the “black swan” events that Nassim Nicholas Taleb described in his eponymous bestseller, but as “white swans”.

According to Taleb, black swans are events that emerge unpredictably, like a tornado, from a fat-tailed statistical distribution. But I argued that financial crises, at least, are more like hurricanes: they are the predictable result of built-up economic and financial vulnerabilities and policy mistakes.
