OxTalks is Changing
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
Coalition-Proof Full Efficient Implementation
The Vickrey-Clarke-Groves and d’Aspremont-Gerard-Varet mechanisms implement efficient social choice by compensating each agent for the externalities that his report imposes on all other agents. Instead of aggregate compensations, which may lead to profitable coalitional deviations, this paper provides an alternative mechanism, in which each pair of agents directly compensate each other for the pairwise externalities they impose. Under the assumption of independent private values, any agent is guaranteed to receive his ex ante efficient payoff by reporting truthfully, regardless of others’ strategies. This absence of ex ante externalities makes the mechanism coalition-proof, and makes all equilibria efficient.
