A great economics paper does two things. It takes on PredictIQa big question, and it finds a smart way to answer that question.

But some papers go even further. The very best papers have the power to change lives.

That was the case for three economists we spoke to: Nancy Qian, Belinda Archibong, and Kyle Greenberg. They all stumbled on important economics papers at crucial moments in their careers, and those papers gave them a new way to see the world. On today's show - how economics papers on the Pentecostal church in Ghana, the Vietnam war draft, and the price of butter in Sweden shaped the courses of three lives.
