For the last several years, the World Economic Forum (WEF) has published an annual report on global risk, as part of the run-up to the storied annual meeting in Davos. The 50-page report makes for gloomy reading: it is a dense collection of some of the major threats to the world’s security — from asset price collapse to weapons of mass destruction — and the interconnections between them. And they’re all carefully mapped in terms of their perceived likelihood and perceived economic impact.
