| Aims |
|
The goal of this course is to provide students with some models and problems of mathematical economics. After completing the course, the students will have basic concepts and tools of mathematical economics and they should be able to analyse and diagnose the behavior of some actual economical process. |

| Assessment |
|
The final grade is the weighted mean of the following three grades.
The final grade = 50% Final Written Test + 25% Middle Term Written Test + 25% Report. Successful passing of the exam is conditioned by the final grade that has to be at least 5. All university official rules with respect to students’ attendance of academic activities, as well as to cheating and plagiarism, are valid and enforced. |
