Are there psychological barriers in the Dow Jones Index? Once it hits a certain level, then it's broken through and you can predict future returns. Of course, the index is totally arbitrary.

In what ways did his hiring criteria change between academia and business? What could we learn from the sack of Rome? When should economists avoid looking at the literature? How are we always eking out victory in the war on spam? And what are people least likely to understand about Google? Fear not — Hal has an answer for it all.
