### Course Syllabus

#### Abstract

The main question of the course is how to aggregate individual interests into the unique social or group one. To answer on this question different concepts of fairness are applied and characterized. The course begins with the simplest game-theoretic models with two participants and then develops to more complicated n-person, dynamic and cooperative games. Another part of the course is devoted to social choice theory mainly to voting problems. The problems of existence optimal solutions and their finding are studied with the help of the modern mathematical methods.

#### Learning Objectives

• The main purpose of the course “Microeconomics 2” is to develop the competence of students in Microeconomics, with an especial attention to decision-making models including game theory and social choice theory.

#### Expected Learning Outcomes

• The student should know cost/profit sharing methods.
• The student should know based competitive economics models
• The student should know methods of finding optimal behavior in some classes of strategic games.
• The student should know optimality concepts on conflict situations and their characterizations.
• The student should know voting models
