What could cause a future financial crash? Ian Goldin, professor of globalisation and development at Oxford University, talks to some of the world's leading economists about whether we have learnt lessons from the 2008 financial crash and whether countries are now better prepared to meet the next crisis. Or are we condemned to another economic meltdown, perhaps even more severe, which would provide new fuel to the fires of populism? A decade ago, the world was taken by surprise. Will it be again? Featuring contributions from the IMF's Managing Director, Christine Lagarde, Lord Nick Stern, Professor Peter Piot, Pascal Lamy and Jeffrey Sachs. Producer: Ben Carter
