Some say economics has all kinds of good tools and techniques, but it has an absence of interesting problems. I look around the world, and I see all kinds of interesting, important problems we ought to solve with the tools we have. Alvin E. Roth
The way I try to simplify my job is that I have two lists - I have a list of all the crazy, interesting problems that I get to solve every day or that need to be solved, and I have a crazy list of things I'd like to invent.
