Semester page for ECON4120 - Autumn 2014

Best approach: send e-mail!
My office is 1243, to the right of the Department's reception. I will try to be available tomorrow, at least after the Friday lunch seminar (but can easily drop that if someone mails and asks to meet).  
The exam is on Monday, as you know; I may even be available on Sunday on short notice (I live only half an hour away from the University).  Again, send e-mail.

On Monday nov. 17, I managed to misinterpret Problem 2 a from the exam from Fall 2011. The correct interpretation of the problem is given by Nils in the (short!) solution note uploaded here.

• I was made aware that the last equation in the solution to the Spring 2012 exam was missing a ' (for derivative). The expression is what one was asked for, G'(k).
  (The note is updated. And, thanks to the student who alerted me.)
• And, the last review lecture: the auditorium was available, is booked, and should show up in the schedule calendar.

- Nils

The upcoming Tuesday: complete the elasticity of substitution, and then - unless I get better suggestions - a general review lecture. 

Then one one covering a recent exam problem set; I suggested in class Wednesday 3. Dec., will try to book usual auditorium at the usual (14.15) time. Will keep you posted. 

Finally: for the "Exercise 1" of the seminar problems, the one with Taylor polynomials: expand around zero, and to check accuracy, compare with what you get by evaluating the function using your favourite numerical toy (calculator, spreadsheet, ...)

Seminar problems etc.:

• Problems for next week posted.
• I realize one of the problems for this week (you should by now be able to tell which one!) required today's lecture.  An apology if I ruined that "test exam" situation.
• Someone requested a Kuhn-Tucker based solution to problem 33. Luckily Kristoffer had already done that. I now also uploaded a suggested solution without Kuhn-Tucker. (Remember that the way the problem was formulated, you have free choice of tool.)
• The most recent exam problem sets will be posted later.

The last two/three lectures

• By tomorrow, bring your calendars to schedule the final (near-the-exam) review lecture. (That one will cover a recent exam problem set, possibly two.)
• Next Tuesday I will finish whatever is left, and then review some theory; If I do not get any requests for review material, I will give a "Mathematics 2 in a nutshell" lecture.

As promised, I've now posted a solution to problem 33 on the course page (link here). I left it as an exercise for you to verify that the multipliers indeed satisfy the K-T conditions.

Seminar problems for next week now available.

For this week it is two entire problem sets. I recommend that you simulate an exam situation: allocate three hours, do what you  can do in that time and/or see how much time you need. And do not open the PDF before you start your stopwatch!

Two full sets might seem to be a lot, but six hours still leaves room for quite a bit of reading given that Math 2 is supposed to be 1/3 of a full-time job.

On October 14: topics from EMEA ch 7 and 12. Not FMEA. (Updated now.) Thanks to the student who notified me of the error.

... copied/pasted a bit too hastily, and assigned problem 86 for the 2nd week in a row. Please replace it by problem 33. - Nils
