Why do some countries become rich while others stagnate? And can you predict which countries become wealthy in advance of them actually increasing their collective GDP? The answer may lie in the complexity of each nation's domestic economy. On this episode we speak with Ricardo Hausmann, a professor and director of the Growth Lab at Harvard University. He helps us understand what economic complexity is, how it's measured, and the process by which countries can move from being less complex to more complex over time.
