Lars Peter Hansen

There is a big divergence between views on a variety of policy issues from fiscal stimulus to financial regulation. It's my hope and my ambition for the economics profession that as we advance our knowledge, that those discussions will narrow in their focus, and that it will help to have more prudent policy-making down the road.

It's kind of a funny way to put it, but if you want to study a dynamic economic system, what you'd like to be able to do is focus on the linkages, say, between asset markets and the macro economy without having to model everything at the same time.
