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.

Everything changed in Bosnia, when General Wesley Clark proved that you could fight a war with high- level precision air strikes and a bare minimum of ground action.

Lord, Bless our enemies; have mercy upon them, may they turn their course and let us alone, and let us live in peace at our homes in our own native land.

We want to live at any price; so we cannot burden ourselves with feelings which, though they might be ornamental enough in peace-time, would be out of place here.

And if we are honest we have to make a distinction between a democratic Israel that wants to live in peace and the terrorists who want Israel wiped out. The Israelis were told to give up land for peace; they gave up the land, but got no peace.
