As I noted in my Nobel lecture, an early insight in my work on the economics of information concerned the problem of appropriability - the difficulty that those who pay for information have in getting returns.

I recognized that information was, in many respects, like a public good, and it was this insight that made it clear to me that it was unlikely that the private market would provide efficient resource allocations whenever information was endogenous.

My teachers helped guide and motivate me; but the responsibility of learning was left with me, an approach to learning which was later reinforced by my experiences at Amherst.

If Trump actually wants to help those who have been left behind, he must go beyond the ideological battles of the past.

The prime minister is not a private individual, but the leader of the Jewish State and the Jewish world as a whole.

Our goal is not to be the biggest. Our goal is to be the best. That is why the aspiration that I have picked is to be the undisputed leader in professional services, and I'm starting with intangible metrics.

A president who aspires to be recognized as a global leader should not personally stake out a foreign-policy goal, commit himself eloquently to its attainment, and then yield the ground when confronted by firm opposition.

That is what happened in 2010. The administration and the leadership of the Republicans thought, 'Well, we're making a deal together; we're showing the world things can be done in a bi-partisan way. We're extending all our tax cuts for two years.'
