Studying the market for salt in 19th century India and the effects on trade of a railroad built 150 years ago led economist Dave Donaldson to important new findings that are relevant today. Donaldson was the 2017 John Bates Clark Medalist, awarded for the most significant contributions by an economist under the age of 40. In this podcast, Donaldson talks about his work on trade and how it benefits economic welfare.
