Administrative Alert (402): Stats, Keys, etc.

June 2, 2009

First, sorry it has taken so long to get this information up on the blog.  I had a number of commitments to the Weidenbaum Center and needed to move back to Richmond for the summer.

Here is the distribution of grades for the 402 sections: 402 Grade Distribution.

Here are the keys to both version of the final exams:
Answer Key_Final Exam_Vaughan_402_Spring 2009
Answer Key_Final Exam (Version 2)_Vaughan_402_Spring 2009

In all borderline situations, a necessary condition for getting “bumped” was a final-exam score on the right side of the cut-off.  So, for example, someone on the borderline of a B+ and an A- needed an A- or better on the final exam to get the bump.

Turns out I will be at the Cleveland Fed full-time next year (more info in a subsequent post).  But Luiggi will be around, and he has your final exams.  You can schedule an appointment to discuss.

Have a great summer!

Further Study (335/402): Barro vs. Krugman

April 30, 2009

In case you want to revisit the Barro vs. Krugman debate as a study break, here is a debate between them on the Charlie Rose show.  It is old — 2004 — but they cover the same issues — growth vs. fairness, etc.   The clip is about 20 minutes long: Krugman vs. Barro.

HT to Kiro Yovkov.

Class Notes (402): NK Model and Prices

April 28, 2009

I have received a number of emails from students confused because I said in class the New Keynesian model predicted a procyclical price level while Barro said it predicted a countercyclical price level.  You may stick with my explanation — which was intended to simplify things.   For a deeper understanding of the difference (as well as a more detailed discussion of my version), click here: sticky-price-model-and-the-price-level see the FAQs in the 402 Exam Locker.
