It is January, the month of the Epiphany. The three kings come to pay homage to a small village perched amongst snow clad mountains. Well, if not quite three kings, certainly a fair sprinkling of princes, princesses, presidents and premiers. Yes, it's time to look out the lederhosen and dust down the dirndl for the annual WEF-fest at Davos.

This year's theme is The Reshaping of the World: Consequences for Society, Politics and Business.
