Dear all,
I'm delighted to announce the next COMSOC Seminar. This Thursday at
15:00 we'll have Aditya Aradhye from Maastricht University talk about
his work on group-strategyproof aggregation rules in multidimensional
domains. I'm including the abstract below and am looking forward to
seeing you here on Thursday.
As always, for more information on the COMSOC Seminar please consult

All the best,
Ulle

Title: Group Strategy-Proof Rules in Multidimensional Domains
Date: Thursday 20 February 2020
Time: 15:00
Location: ILLC Seminar Room F1.15, Science Park 107, Amsterdam
Abstract: We consider a social choice setting in which the alternatives
are binary vectors and the preferences of the agents are determined by
the Hamming distance from their most preferred alternative. We restrict
the set of social choice functions to 'rules' which satisfy unanimity,
anonymity and neutrality. As the preference domain is not the universal
domain, the Gibbard-Satterthwaite Theorem does not hold. Hence, we study
a stronger notion: group strategy-proof rules. We show an impossibility
for strongly group strategy-proof rules.
