Agenda-manipulation in ranking by Ludvig Sinander

Join us for the another event in the Microeconomics Research Seminar Series, Spring Term 2022

Ludvig Sinander, from Nuffield College, University of Oxford, will present research on Agenda-manipulation in ranking.

Abstract

We study the susceptibility of committee governance (e.g. by boards of directors), modelled as the collective determination of a ranking of a set of alternatives, to manipulation of the order in which pairs of alternatives are voted on -- agenda-manipulation. We exhibit an agenda strategy called insertion sort that allows a self-interested committee chair with no knowledge of how votes will be cast to do as well as if she had complete knowledge. Strategies with this 'regret-freeness' property are characterised by their efficiency, and by their avoidance of two intuitive errors. What distinguishes regret-free strategies from each other is how they prioritise among alternatives; insertion sort prioritises lexicographically.

This seminar will be held at 1pm on Zoom. This event is open to all levels of study and is also open to the public. To register your place and gain access to the webinar, please contact the seminar organisers.
