Populist leaders and movements are on the rise across the world, but why now? Populism has been around since Ancient Rome. In this podcast, economist Guido Tabellini says the 2008 global financial crisis and technology are driving the recent resurgence. Tabellini says with growing inequality people disappointed by the policies of the past that have excluded them from the benefits of the global economy are voting more along cultural identity lines. It's the nationalists versus the cosmopolitans. Guido Tabellini is Professor of Political Economics at Bocconi University in Milan, Italy, and delivered the IMF's Annual Richard Goode Lecture on his research.
