This paper provides an `escape route' from the efficiency-equity trade-off in the School Choice problem. We achieve our objective by presenting a weak notion of fairness, called τ-fairness, which is always satisfied by some allocation. Then, we propose the adoption of the Student Optimal...

This paper studies the sequential mechanisms which mimic matching procedures formany-to-one-real-life matching markets. We provide a family of mechanisms implementing thestudent´ optimal allocation in subgame perfect equibrium.
