It's no news that the $30 spike was a bubble. And this is a required paper written by a few econ students. Am I missing something here?
EDIT:
It's not a peer-reviewed paper - it was a class assignment for an undergraduate course in economics. Glad they've done it, but it's pretty clumsy. Typical academic "publish or perish" stuff: I have to write a paper, so I'll write for the sake of writing, showing that I have been successfully indoctrinated by teachers into a particular way of thinking and parroting. The conclusions are stating the obvious and the trivial, but in a pompous, academic language.
+1. You said it better
