### Materials

You do not have to turn this problem set in. It will be covered in your first review session. Make sure that you understand the basic material here.

These notes give you an idea of which parts from your Matrix Algebra course are essentials for the current course. More advanced topics will be covered in a self-contained manner.

These notes cover the material of the first three weeks in the course. These notes are not a substitute for the book, in particular, I have not given proofs. In the book, you can find the missing steps. In the lecture slides, we will cover the most important points and provide additional examples.

Please note, typos in the numerical example for implicit function theorem. See Lecture slides for Lecture 4 for corrections.

Here are the slides to Lecture 1

Problem Set 1 due April 22 at 23:59. Typo correction: In question 1 a) i), add 'write' before ....the equation system...

Some typos corrected.

Due April 29, 23:59. Please note typo in Q1, b). Should read (x,y,w) = (1,1,1). I have now corrected in this version.

Typos corrected in the example for implicit function theorem

This is the video for lecture 4. Please note that there is a typo in the example of the implicit function theorem. It is corrected in the lecture slides.

Lecture 5 slides with some typos corrected.

Due May 6, 23:59.

Lecture 6 slides

Slides for lecture 7

Second part of lecture notes

Due May 13. Correction to harmonic mean. For problem 4d, you may take n=1. For question 3, can you see the connection to UMP with Cobb-Douglas and CES functions? In problem 2, I should have written that the consumptions x_i are also positive.

Some typos corrected (Stone-Geary MRS in particular).

Video of lecture 9

I have listed here the most important topic in the course.

Please note that there is an interior solution for problem 2 (and (0,0)) is not the correct solution, the first order conditions are correctly written so the rest of the problem is as it should be.
