As a matter of illustration, here are possible topics: - conflict and cooperation - voting - measurement of power - social choice - fair division
Learning outcomes
 At the end of this learning unit, the student is able to : 1 This course is an introduction to mathematical modelization in social sciences at large (economics, political science, sociology, law). It is not a course in mathematics and the prerequisite do not go beyond the basic college mathematics. Its aim is to help students to develop an analytical capacity through a systematic and rigorous use of simple concepts of game and decision theory.
Content
At the end of this course, students will be able to
• to understand the value of formalization for the social sciences and to recognize the main tools used in this field,
• to build models of strategic situations and analyze them using cooperative and non-cooperative game theory,
• to use computer simulation of social phenomena using a programming environment (NetLogo).
Topics covered:
• The notion of "model" in social sciences
• Basic mathematical concepts useful for social sciences: sets, truth tables, relations, matrices, functions, permutations and combinations, etc.
• Rational choice model in non-cooperative game theory: how to predict the outcome of a strategic situation involving several players?
• Models of games with coalitional structure (Shapley value): how to distribute fairly the gains from a joint effort?
• Matching models (Gale-Shapley algorithm): how to match requesters and givers?
• Models of voting games and power indices: how to measure power?
• Models of collective choice and voting procedures: how to decide collectively?
• Social science simulations: why and how to simulate our social universe?
• Models of transition between states (SIR model): how to predict the evolution of an epidemic?
• Growth models: what are linear and exponential growths?
• Statistical models: how to make simple predictions in statistics?
The course consists of a series of lectures completed by exercises.
Teaching methods
The course is structured around lectures and practical work. Participation in sessions of practical work is required.
Evaluation methods
A written exam organized in the regular session, combining practical exercises and multiple-choice questions.
