With the world more economically and financially integrated than at any time since the late nineteenth century, a global central bank and a world currency would make more sense than our confusing, inefficient, and outdated assemblage of national monetary policies and currencies.

NEW YORK – Today’s world is more economically and financially integrated than at any time since the latter half of the nineteenth century. But policymaking – particularly central banking – remains anachronistically national and parochial. Isn’t it time to re-think the global monetary (non)system?
