Golden passports and cash for citizenship - a legitimate way to for countries to get investment or a scheme open to abuse and corruption? That’s the big question we’ll be looking at on this episode of Business Weekly. We look at why the wealthy want to acquire them. We also hear from Cyprus where a passport corruption scandal has rocked the nation. Meanwhile, the winner of this year’s Nobel Prize for Economics tells us about the unusual way in which he discovered he'd won, and of course, about the game theory that netted him and a colleague the award. And we hear from the African animators who are taking on the world. Business Weekly is presented by Lucy Burton and produced by Matthew Davies.
