Redesigning the high school placement mechanism in Turkey

In this thesis, we study the placement mechanism used for matching eight grade students and high schools in Turkey. We observe that the mechanism does not satisfy the most desirable properties such as individual rationality, strategy-proofness, respecting improvement, non-wastefulness, and fairness. In order for the system to have the desired properties, students must be able to present their original preferences. However, in the current system, this is not possible due to preference restrictions. Our approach is to improve the students' welfare by redesigning the mechanism.
