Professor Robert Shiller: This is Economics 252, Financial Markets, and I'm Bob Shiller. Let me begin by introducing the teaching fellows for this course; and so I have them up here. We have five teaching fellows at this time and they're from all over. I like to put their pictures up so you'll know who they are. The teaching fellows are very international and that reflects my intention to make this a course that is also very international because finance is something about the whole world today, not just the United States. So we cover the world very well with our T.A.'s.
