The Nobel Memorial Prize for economics was announced a few weeks ago. It was for contract theory. Normally, we'd interview the prize winners and then do a lot of clever talking about what it means, but this year we tried something different.
We called on one of our favorite economics experts, Tim Harford, and asked him how we should think about contract theory. His new book, "Messy," is about unlocking creativity, and it looks at how disorganization and improvisation are often the routes to invention.
