14.32  Econometrics

Your graded final exams are with Emily Gallager in E52-262.  The class average on the final was 74.9 out of 90, and the standard deviation was 12.2.  You should also be able to view your final course grades on Websis.  This has been a great class to TA; thank you all for making it so interesting and fun for me.  Have a great summer.

Part II (e) had a typo, you need to assume cov(zi,ai)!=0, but cov(zit,eit)=0.  I mistakenly had both cov(zi,ai)!=0 and cov(zi,ai)=0.  Thanks to everyone who went through these so carefully!

There was a typo in (a) of Part 1, it should say that heteroskedasticity won't bias slope coefficients, not standard errors.  The updated version is posted.

You can pick up your unclaimed problem sets from my mail folder on the 3rd floor of E52.  If you go right out of the elevators, then left, the mail folders are down the hall on the right side, across from the vending machines.

Several of you noticed that the numerator degrees of freedom for Part I (e) was incorrectly stated as 1 instead of 2.  I have updated this and posted it.
