Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
- distinguish between decision- and game-theoretic problems
- identify strategic interactions
- describe strategic interactions using formal models and approaches learned during the course
- express the importance of incentive compatibility and individual rationality when designing strategic environments.
APPLYING KNOWLEDGE AND UNDERSTANDING
- apply mathematical modeling to real-world strategic interactions
- use the concepts taught to solve and analyze such mathematical models
- prove results in game theory and mechanism design
- translate the models’ insights into various real-world situations, such as auction design.
Teaching methods
- Face-to-face lectures
- Individual assignments
DETAILS
In the face-to-face lectures, we will introduce, motivate and discuss the course topics and models and how they apply to various economic and other real-world settings. Moreover, we will prove important game-theoretic/mechanism design results thereby acquiring the relevant skills to formally set up and analyze models individually and solve problems together in these lectures. In addition, we will apply this knowledge to real-world settings and discuss the insights game theory and mechanism design can deliver in practice. The individual assignments, which will take the form of problem sets, are designed to have the students solve problems and prove results by themselves further enhancing students' understanding of the topic and their ability to study strategic interactions as well as their design. After their submission, we will discuss the problem sets and insights from solving them in the class.

ATTENDING AND NOT ATTENDING STUDENTS
Both attending and non-attending students will be treated identically and the form of the assessment is exclusively written. The students can take either two partial exams or one general exam which account for 80% of the final grade. The remaining 20% will be based on individual assignments in the form of problem sets. The written exams ask open questions to prove theoretical results, solve problems related to those presented in the lectures and individual assignments, and discuss the implications in and the relation of findings to the real world. The individual assignments will be similar to the exam and will consist of proving theoretical results and solving problems as well as discussing the findings. Both assessment methods verify the students’ ability to identify, formalize and solve strategic interactions, prove results in game theory and mechanism design, as well as the ability to apply formal reasoning to real-world problems.
Teaching materials
ATTENDING AND NOT ATTENDING STUDENTS
There is no mandatory textbook for the class. The material in the form of lecture notes/slides will be distributed during the semester and a list of additional readings will be provided.
