The Diamond-Water Paradox

Adam Smith, the father of economics, had a problem. He believed in the wisdom of markets--that the free market would always settle on the best price for something. That price would be an expression of how valuable that item was. The problem: diamonds are more expensive than water and water is more valuable to us than diamonds.

We talked to about the paradox and Smith.
