• Remember: justification is the main part. You cannot just fill in the conclusion.
• Remember that you are allowed to bring all books, notes, and other written or printed matter with you, and pocket calculators too. (Batteries are your responsibility!)
  • But you are not permitted to submit anything readymade.
    You must write everything on the papers handed out. (And not on the questions sheet!)
• The exam is not the right time to save paper - you would want to write so clearly and legibly that we can read what you are doing (which is necessary to get credit).
  • Want to delete something? Strike it out - you cannot use an eraser! You are supposed to use ink (blue or black).
    For students new at UiO: it is "carbon paper" that produces two blueprints in addition to the top layer. Two handed in, one retained by you. (And so erasing would make lots of illegible mess.)

And if you think...

So it was even more unfinished. Even more to do. 

I see that the version posted a week ago, missed a "/" in 2(b): somewhere therein, a "1/t" was only "1t", and that does make enough difference to update. 

Message from a week ago:

It was pointed out to me a "new" kind of error: in the solution note for spring 2017, not even the questions of problem 3 were right. The reason was that the "final" version was deleted by mistake (my bad, of course) and what you saw was the most recent that was still left. I have reconstructed and re-uploaded; see disclaimer page 1, and note that in addition there is a correction in problem 2 as well. 

I got a question on one of the examples in the note. It could have been worded better yes; hopefully the new version does that. No substantial change intended. - Nils

Sign corrected (unnoticed until now, it was the sign of something that in the end becomes zero) - and the previously indicated correction actually carried out this time, hopefully completely.
Correction uploaded. Thanks to one of you. - Nils

As per the message 23rd of October, those who submitted a 2nd time had all gotten approved.
The message posted Wednesday (which this supersedes) was due to one missing entry in Fronter. There is one person whose feedback was lost. (Human error, not checking that it was saved.)

Consequence: one person who resubmitted, would not have found any other confirmation of approval except the October 23rd message - and still the comment box is empty, as that text was lost. To that person: If you want more detailed feedback, you can contact me (Nils) and I'll have another look at it.

For other questions: Contact the Department of Economics.

Ola is likely to finish a bit early, and possibly the best use for the last lecture is to focus on the exam. 
One suggestion could be to cover one more exam problem set and exam-related review (like: how much are you supposed to write, or "course in a nutshell" or topics by request).
In order to give you time to solve one more exam, it should be after the last ordinary seminar. The November 27th time slot looks good.

So:

• Ola will discuss this suggestion with you on Thursday in order to avoid any time clashes;
• Probably, we will cover the last ordinary exam (now uploaded).
• The schedule will be updated when everything is decided.

Nils

There will be a lecture on Friday November 3th. Check the schedule for details.

Due to a misunderstanding, there will be no lecture today. A new date for a make up lecture will be announced tomorrow.

Due to a misunderstanding, there will be no lecture today. A new date for a make up lecture will be announced tomorrow.

So I (Nils) put the Leibniz rule into the lecture schedule and forgot to notify Ola - who covered it yesterday. A note is uploaded now (and revised half an hour later - if you loaded it before 0830, then please reload). The lecture schedule will be updated.
Apologies for the glitch here.

Seminar problems updated too. 

At yesterday's workshop, we covered problem 2(=28) and then the rest very roughly.
About ten of you were present at the workshop, and I've had remarks that the timeslot is inconvenient. 

Question: is there need for more review?  If so, please let Ola know. 
- Nils

So we will use part of Thursday's workshop - say, from 1700 - to review the term paper problem set, starting at Problem 2 = Compendium problem 28.  No chance to cover the entire problem set, but we hope to find space for a second review session.

Sorry for the short notice, but it suddenly appeared to be a feasible solution. - Nils

The papers that were resubmitted by today's deadline have all been approved, though not all of you are overly risk-averse ... 

We are looking into scheduling a lecture reviewing the problem set. Watch this space.

And, seminar problems for next week to be posted tomorrow.

Updated with confirmed deadline and set (the boldfaced part).

Term papers: the pass/fail part:

• You should find (in Fronter) whether your term paper was approved
• Those who did not get it approved, will have a resubmission deadline next Monday the 23rd at 1400. There are no changes to the problem set (i.e., you have the same problem set to solve; you can re-use (better) parts of your first attempt, but you should upload a complete paper with answers to everything). 
• If you do not see a decision on your paper, please contact the administration.

The feedback part:

• Attached to your papers, you should see shortform comments on what you did well and not so well.
• If that is missing, you can send me (Nils) an e-mail. 
• You should be cautious and not too over-optimistic when you interpret the comments:...

• Ola is at least not behind schedule, and Monday's lecture may start on Thursday's topics.
• We hope to get your term papers done quickly. You will get shortform comments on what you did better and what you did worse - except, those of you who did not even attempt enough of the set to get it approved, will not get much (if any) feedback.
• When all your results are published in Fronter, there will be announced a deadline for a last chance for those who did not get approved - and you will only get a few days. 

Nils

So I've already had a question on how it should look like.

You should

• Write longhand. Yes, we want a handwritten paper like you would do on the exam.
• Scan it to a PDF file. Upload that to Fronter.

How/where to scan?

• The libraries: https://www.ub.uio.no/english/using/printing-copying/#skanne / https://www.ub.uio.no/bruk/utskrift-kopiering/#skanne
• Most of you have good enough cameras as well - for example on cellphones. But then you should beware the following: 
  • You will need some utility/app that converts multiple pictures to a single PDF.
    No problem if you use an ordinary computer, but possibly not installed in your cellphone by default.
  • You might need so...

A corrected version has been uploaded. If you are not sure you have the right one: the filename ends with 17c.pdf (the "c" for corrected).

The error was that f(x,y) in problem 1, is not equal to w-14, but to y w(x,y) - 14. The missing "y" has been inserted. 

My apologies for the inconvenience. Nils. 

You will find the compulsory term paper on the semester page for ECON4120.

For questions, please contact the Department of Economics.

Ola will be done with optimization by the first hour on Monday, and will then start on linear algebra.  

... marked with "Update".

Some of you are new to this university (/country) and I've had questions on what an exam paper should look like - how much are you supposed to write, etc. For one exam, I handwrote something that could give you an idea.  You may want to leave it unseen until you have attempted to solve that exam though, but in any case: spring 2014. (It also contains some comments, but I think it should be clear what is not supposed to be is clear what should not be in an exam paper.) Also, at some stage someone asked for what is the "bare minimum", and for one exam there is such a note as well - but that exam will be assigned for seminars, I think.

Furthermore:

• Open-book exam. Anything printed or written can be used. Your notes, others' notes, problems, solutions ...
• It is usually a good idea to start on a new sheet of paper for each problem - then you can tear a sheet apart without ruining something else. (But you can also cross out things...

As announced in class: the "workshop" is experimental for this course (they use it in similar courses otherwise).  It is you who are supposed to do the "work" ;-)

Here is what we think should go on:

• You have in advance had so much of a look at the seminar problems that you have an idea what you might need help on.
• You start working on the seminar assignments, discussing with each other and/or the seminar leaders. Identify issues, get an explanation, get back at solving. 

The seminars will then review the problems. If two weeks later you want to discuss problems that have already been covered in seminars to make sure you have finally understood them, then please do so.

It seems that Friday's lecture has to be moved. You will all get an e-mail notification about the details.

A new lecture will be scheduled next Tuesday 1615-18 (like yesterday's, but in a different room: auditorium 2). So the schedule for the next days reads: Thursday 1015; Monday 1615; Tuesday 1615.
