Template-Type: ReDIF-Paper 1.0 Title: An analysis of the German university admissions system Author-Name: Alexander Westkamp Author-Email: awest@uni-bonn.de Classification-JEL: C78, D02 Keywords: University Admissions; Matching; Stability; Strategyproofness; Complex Constraints Abstract: This paper analyzes the sequential admissions procedure for medical subjects at public universities in Germany. Complete information equilibrium outcomes are shown to be characterized by a \emph{stability} condition that is adapted to the \emph{institutional constraints} of the German system. I introduce \emph{matching problems with complex constraints} and the notion of \emph{procedural stability}. Two simple assumptions guarantee existence of a student optimal procedurally stable matching mechanism that is strategyproof for students. n the context of the German admissions problem, this mechanism weakly Pareto dominates all equilibrium outcomes of the currently employed procedure. Applications to school choice with affirmative action are also discussed.
