III. Course objectives
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.	

IV. Course contents
1)	Mathematical models in economy: Arrow-Debreu model, consumer’s problem, maximal elements, Walras equilibrium points, generalized game, Nash equilibrium points, optimization problems.
2)	Background in multivalued analysis: basic concepts, continuity, selection theorems, fixed point theorems.
3)	KKM lemma and John von Neumann theorem.
4)	Variational inequalities
5)	Maximal elements, fixed points, equilibrium points: existence and approximation methods

VII. Didactic methods used
Expositions: description, explanation, class lectures, dialog-based lectures, lectures with demonstrations, introductive lectures,  synthesis lectures. 
Conversations: debate, dialog, introductive conversations, conversations for knowledge consolidation, conversations to systematize and synthesize knowledge 
Use of problems: use of problem questions, problems and problem situations. 
Discovery: directed and independent rediscovery, creative discovery, inductive discovery, deductive discovery, discovery by documenting, experimental discovery.

VIII. 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.
