Abstract

In many school choice practices, scores, instead of ordinal rankings, are used to indicate students’ qualification. We study school choice problems where students have ordinal preference over schools while their priorities at schools are in the form of cardinal scores. The cardinality of scores allows us to measure the intensity of priority violations and hence relax stability by proposing epsilon-stability. We also propose the epsilon-EADA mechanism to select the constrained efficient matching under epsilon-stability.
