What policymakers (and econometricians) should recognize, then, is that societies face a meaningful set of choices about alternative economic policy … - Thomas J. Sargent

Q: “Professor Sargent, can you tell me what CD rates will be in two years?”
Sargent: “No.”

My published work is just a record of my learning. I'm sharing it with people so they won't make the same mistakes that I did. It's been a painful and slow process. My work is like a journey, a journey of discovery.

These ideas have implications not only for theoretical and econometric practices but also for the ways in which policymakers and their advisers think about the choices confronting them. In particular, the rational expectations approach directs attention away from particular isolated actions and toward choices among feasible rules of the game, or repeated strategies for choosing policy variables. While Keynesian and monetarists macroeconomic models have been used to try to analyze what the effects of isolated actions would be, it is now clear that the answers they have given have necessarily been bad, if only because such questions are ill-posed.
