# Choice and Decision Theory

Area of studies: Applied Mathematics and Information Science
When: 3 year, 1, 2 module
Mode of studies: offline
Open to: students of one campus
Language: English
ECTS credits: 5
Contact hours: 60

### Course Syllabus

#### Abstract

This course presents an introduction to individual and social choice and decision theory. We will introduce and analyse models of individual decision making in forms of binary relations and choice functions, their rationalization by utility functions and properties of rational choice, methods of collective decision making and their properties, problem of power evaluation and theory of matchings as an example of applied problem.

#### Learning Objectives

• to familiarize students with the basic concepts, models and statements of the theory of choice and decision making
• to familiarize students with the power assessment in voting and in network structures
• to familiarize students with the matching theory

#### Expected Learning Outcomes

• know centrality measures in networks
• know choice functions and their rationalization by utility functions and binary relations
• know properties and special classes of binary relations
• know properties of social choice rules
• know the concept of manipulation in collective decision making
• know the concept of ordinal utility
• know the deferred acceptance algorithm and be able to use it in order to find a stable matching

#### Course Contents

• Mathematical Model of the Decision Making Situation
• Utility, Preference and Choice
• Internal and External stability
• Networks
• Political Decision Making
• Polarization in parliaments: uni- and multidimensional cases
• Assignment problem

#### Assessment Elements

• homework
• mid-term exam
The mid-term is a written test in StartExam platform with asynchronous proctoring by Examus. The rules of the mid-term are available at https://elearning.hse.ru/en/student_steps/ Asynchronous proctoring means that all the student's actions during the exam will be “watched” by the computer. The exam process is recorded and analyzed by artificial intelligence and a human (proctor). The mi-term consists of several questions. In some of them students should provide a short answer, in others they have to do a matching or answer the multiple choice questions. Students are not allowed to use a mobile phone or any other devices and communicate with classmates and any other people during the mid-term.Please be careful and follow the instructions (https://elearning.hse.ru/en/student_steps/) clearly!
