Around the world, the middle class is expanding at a rate we have never seen before in history. Homi Kharas, a senior fellow in the Center for Sustainable Development at Brookings, joins David Dollar in this episode to discuss how that global middle class is defined and where growth is concentrated. Kharas also explains how preferences among the global middle class will affect production, trade, regional value chains, and efforts to address climate change for years to come.
