ILLC Workshop on Collective Decision Making 2015

To mark the end of an NWO project on preference aggregation, we are organising a small workshop on all aspects of collective decision making in the centre of Amsterdam. The main theme of the workshop is "beyond preference aggregation". That is, we will focus specifically on (1) what one might want to do with preferences beyond aggregating them and (2) what one might want to aggregate beyond people's preferences. Speakers will consider these and related questions from the perspectives of a variety of disciplines, including artificial intelligence, computer science, logic, economics, political science and philosophy.

There will be no registration fee and everyone is welcome to attend. However: please register!
