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.

Martin Luther King, Jr. Day is a time to honor the greatest champion of racial equality who taught a nation - through compassion and courage - about democracy, nonviolence and racial justice.

I believe in decentralized democracy.

Unity in faith is theocracy; unity in politics is fascism.

If you want to have a big impact, government is the way to do it. Just think of the number of people you can touch.
