This course deals with basic concepts of theory of committees, which is a mathematical theory of group decision making situations, through discussion, group work, lectures, and working on exercise problems. Specifically, this course takes up: “simple games,” “committees,” “desirability relations on coalitions,” “cores of committees,” “consistent coalitions,” “permissible ranges of decision makers,” “permission games,” “hopefulness relations on coalitions,” “stable coalitions and stable alternatives,” “postulated permissible ranges,” “regretless alternatives,” and “characterizations of cores of committees.”

This course aims to cultivate the students’ abilities to understand basic concepts of theory of committees, and also to convey them to others concisely.

### Student learning outcomes

Upon completion of this course, students should be able to:
1) State the definitions of basic concepts used in the mathematical theories of group decision making situations; and
2) State the analysis methods in the mathematical theories of group decision making situations.

### Keywords

simple games, committees, desirability relations on coalitions, cores of committees, consistent coalitions, permissible ranges of decision makers, permission games, hopefulness relations on coalitions, stable coalitions and stable alternatives, postulated permissible ranges, regretless alternatives, and characterizations of cores of committees

### Competencies that will be developed

 ✔ Specialist skills ✔ Intercultural skills ✔ Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

### Class flow

[Important notice]
If the number of registered students exceeds the capacity at the end of the course registration period, a lottery system will be used to determine which students are admitted.
The registered students will receive emails notifying whether or not such lottery took place.
If a lottery did take place, no additional student will be admitted to the course.

[Class flow]
One class deals with one basic concept.

The students examine definitions and analysis methods of basic concepts, first individually, second in pairs, then in groups of four, and finally with the class as a whole. Then a lecture on the basic concept is presented, and the students work on exercise problems. At the end of the class, each student writes and submits a “summary report” on what he/she learned through individual observation, other students’ ideas, the lecture, and exercise problems.

### Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

### Textbook(s)

Takehiro Inohara, “Rationality and Flexibility,” Keiso-syobo, 2002 (in Japanese) (Section 1.2, Section 2.1, Chapter 7, Chapter 8, Chapter 9）(ISBN-10: 4326502223, ISBN-13: 978-4326502226)

### Reference books, course materials, etc.

Takehiro Inohara, “Emotions and Perception,” Keiso-syobo, 2002 (in Japanese) (ISBN-10: 4326502231, ISBN-13: 978-4326502233). Course materials are found on OCW-i or provided during class.

### Assessment criteria and methods

Assessment will be based on “summary reports” written during each class (50% in total) and the final examination (50%).

If you are absent from a class, regardless of the reason, points are subtracted from the assessment portion of the "attendance and contribution to classes."
There are no make-up assignments.
Read the course materials posted on OCW-i to find out the content of the class you missed.
