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.

We just need to make sure that we get somebody in there that respects the Constitution, respects the rule of law, that restores the proper balance between the states and federal government. I have great confidence Jeb Bush would do that.

Arizona, our beautiful state, was built on mining. Copper is huge here, and now uranium. And then we have the federal government coming in, writing all these rules and regulations and telling us that we can't do this and we can't do that. We need concise, clear answers.

That is why I came to conclusion that the election must take place, so that the republic can have a government. If I were to say that everything will change for the better immediately, that would not be true. The struggle will continue for a long time.

In historical messianism, the reign of the Messiah is brought about by a Jewish ruler powerful enough to gather the Jewish exiles back to the land of Israel, reestablish a Torah government there, and rebuild the Temple in Jerusalem.
