On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
To reserve a time to meet with the speaker, please register at the following form:

Abstract:
A seller is selling multiple objects to a set of agents. Each agent can buy at most one object and his utility over consumption bundles (i.e., (object,transfer) pairs) need not be quasi-linear. The seller considers the following desiderata for her mechanism, which she terms desirable: (1) strategy-proofness, (2) ex-post individual rationality, (3) equal treatment of equals, (4) no wastage (every object is allocated to some agent). The minimum Walrasian equilibrium price (MWEP) mechanism is desirable. We show that at each preference profile, the MWEP mechanism enerates more revenue for the seller than any desirable mechanism satisfying no subsidy. Our result works for quasi-linear type space, where the MWEP mechanism is the VCG mechanism, and for various non-quasi-linear type spaces, some of which incorporate positive income effect of agents. We can relax no subsidy to no bankruptcy in our result for certain type spaces with positive income effect.
