Fair student placement

We revisit the concept of fairness in the Student Placement framework. We declare an allocation as $\mathrm{\alpha }$ ‐equitable if no agent can propose an alternative allocation that nobody else might argue to be inequitable. It turns out that $\mathrm{\alpha }$ ‐equity is compatible with efficiency. Our analysis fills a gap in the literature by giving normative support to the allocations improving, in terms of efficiency, the Student Optimal Stable allocation.
