(NO=norsk, EN=Engelsk)

Teaching exam periods:

The course has teaching/evaluation in the August block.

Course frequency: Annually

First time: 2007H

Preferential right:

M-ECON and M-ØA.

Course contents:

The course covers mathematical tools that are assumed to be known in courses such as, for example, ECN311 (Microeconomics) and ECN301 (Econometrics). The course is a compulsory course for the M.Sc. degree in Economics at School of Economics and Business, NMBU. Topics covered in matrix algebra include: Summation operators, types of matrixes, matrix operations, Gauss-Jordan elimination, determinants, the inverse of a square matrix, matrix differentiation, Cramer's rule, and the matrix approach to regression. Topics covered in optimization include: Elasticities, the chain rule, unconstrained optimization, equality contrained optimization (Lagrange), inequality contrained optimization (Kuhn Tucker), implicit funtion theorem, and envelope theorem.

Learning outcome:

The student should know:

- Basic matrix algebra

- Calculus of one and several variables

- Concavity and quasiconcavity

- Unconstrained optimization

- Optimization with equality and inequality constraints

- Implicit function theorem

- Envelope theorem

The student should be able to:

- Formulate and solve economic problems

- Work independently with economic problems

- Solve problems that are relevant in economics, for example, optimization and comparative statics problems

The student should obtain analytical skills that are needed in more advanced courses in microeconomics and econometrics

Learning activities:

The course consists of lectures, exercises and studies of the textbook. The students are encouraged to work in groups.

Teaching support:

There will be exercises with teaching assistant(s).
