I (Nils) will be available most of this week from lunchtime on. I will carry my phone for when I am in a different room, and since I will not check my e-mail constantly, you should not hesitate to phone or text.
(To the extent I can issue orders, that is one: do not hesitate to use the phone, or ask the Department office next door to call me. I'm available on two minutes' notice.)
Phone no.: 90 16 38 93.

Also, as far as I know the procedures in case of issues at the exam: the department administration will be phoned, and will contact the teachers. Should a backup phone number be needed, then they can check this space to find mine.

I (Nils) have to cancel next week - and thereafter you have exams, so please rather send me an e-mail.

I updated the schedule for the last three lectures, and posted seminar problems for both the upcoming and the final seminar. For the review lecture in December, the most recent ordinary exam - spring 2016 - will be covered. That is uploaded as well. 

For the term paper walkthrough this Friday, I hope to have handouts for you.

The following may not find their way into the lecture schedule:

The lecture this Friday:

• Starts 1330, covering the term paper problem set.
• Then ordinary lecture. Topic TBA when I know how far we got by tomorrow.

The review lecture:

• Tentatively scheduled for Friday the 16th of December
• 1330 then as well, why not. Auditorium 7, as usual.

Again, a full exam. There will be more of those.

I assigned quite a lot of problems now - too much, but with suggested priorities. The reason for doing so, is to enable you to get a first idea of how much time an exam problem set takes with your skills as of now. 

More exam problem sets will be assigned for later seminars, and you can track your progress. 

• The results are now available in Fronter (26th of October)
• As announced in class on Friday, the resubmission deadline is November 1st, by 3pm for those who failed. You must deliver the paper in Fronter, in the folder "Hand in second attempt to those who received "not passed" ".
• Those who failed will get a second attempt, and may hand in a new answer (to the original Compulsory assignment ).

Most - but not all - of those who failed, did so over not attempting to solve enough to pass - or just the bare minimum, but of insufficient quality.
There is, however, a strictly positive number who failed over trying a lot and messing up all too much of it. 

There are brief remarks (in Fronter) for nearly each letter-enumerated item of each paper. We did not ask the comittee to perform a...

So I had to revise the problem set. I apologize for any inconvenience. - Nils

As if you did not have enough to do? Show must go on, though; the problem document is updated. - Nils

I (Nils) was made aware that my website still says consultation hours Tuesdays, not Wednesdays. 

Right now - with the term paper in the works - there is no other possible change than "both": Today (Wednesda) 13-15 AND next Tuesday 13-15.  (And Wednesday 13-15 although it is hardly any use right before deadline.)

Hope I remember to correct it afterwards. 

- Nils

In case you are stuck on the term paper, I still have consultation hours Wednesdays.  And I will try to be available next Tuesday.

Like this: http://www.uio.no/studier/emner/sv/oekonomi/ECON4120/h16/beskjeder/cellphonephoto.pdf . Do not spend time typesetting. 

(If you wish to learn how to typeset math, then I suggest LyX , as learning LaTeX could take some weeks.)

As promised.

• The envelope theorem is largely covered. Friday, that will be concluded - and the rest of the lecture will cover some additional bits and pieces of constrained optimization.
  Tuesday, Ola takes over, starting with linear algebra.
• The compulsory term paper: with reservation for changes, we intend to set the hand-in deadline to Wednesday the 12th of October, and hand it out two weeks earlier.
• Problem set for next week posted.

If you attend the Monday seminar, you may want to start already now. Then, you can make use of the Kuhn--Tucker conditions (the very last conditions on the board this lecture) - or if you do not yet feel comfortable with it without any example worked though in lecture, you could split between stationary points and boundary points. If you do the latter, then check the sign of the multiplier.

I messed it up when I tried to write it in a simpler way. Revised now.

But we have covered the intermediate value theorem.

Thursday: Max/min. 

Problems: More likely Friday, but when a break appears natural.

The course web site has been updated with, among other things, the first seminar problem assignment.

Regarding the problems for this week, they will be covered either Thursday or Friday. 

Tuesday we will continue with limits, due to my blunder wasting a third of Friday.

Thursday or Friday, we will cover at least some of the following problems, subject to time and demand:

1. Through this problem, let f be a convex strictly increasing function; part (a) does not utilize all these properties, but in part (b) we shall specialize to an exponential function. 
   (a) Explain why it is so that (edit: "for all x" was missing here!) if \(f(x)>x\) for all x, then \(f(x)>f^{-1}(x)\) for all x.
   (b) Ther...

Continuing with the log and how to differentiate it.

Question: if I give you the graph of a one-to-one function, do you then know how the graph of the inverse function looks like?

... and the teaching schedule is updated, though not proofread for the new edition of the book. 

The "new" slides are the two last of the revised file, available from the semester page or through this direct link: http://www.uio.no/studier/emner/sv/oekonomi/ECON4120/h16/m2introslides.pdf
