Lex

Gold standard

Robert Zoellick, president of the World Bank, has argued for a new effort to stabilise the world's currencies - with gold playing a role. Lex's John Authers and Edward Hadas debate whether the idea makes sense in theory, and whether it is plausible in practice. The Lex video is an experiment in financial journalism that aims to give you an insight into the debates that shape each day's Lex column.
