OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk

Abstract:
Empirical analyses of school choice report standard statistics of student outcomes that are the same for a variety of different mechanisms. This paper explains this puzzle as being driven by two factors: market size and the invariance properties of the statistics for which the equivalence has been observed. In large markets, strategy-proof and efficient mechanisms lead to asymptotically the same realized outcome statistics. Furthermore, many standard mechanisms—such as serial dictatorship or top trading cycles—lead to the same expected outcome-statistics already in finite markets under the additional assumption that the distributions of preferences are exchangeable.
