Africa Institute for Research in Economics and Social Sciences is organizing a seminar on Tuesday, March 14th at 12:30 p.m at the Rabat Campus of Mohammed VI Polytechnic University (Teaching Building B, First Floor) on ''Weakly Separable Committee Rules wIth Diversity Constraints
Our guest speaker for this event is Mustapha Diss, Professor at FGSES.
We address the problem of electing a committee subject to a diversity constraint. Given a set of candidates and a set of voters, each voter being represented by a linear order, the goal is to select a fixed-size subset of candidates by compounding the excellence of the candidates (according to voter preferences) and some diversity requirements. The grounding assumption is that the set candidates is slotted into at least two groups according to a specific attribute such as gender, religion, ethnicity, qualification, political orientation, and the diversity constraint takes the form of a vector of integers specifying the lowest number of candidates required from each group. In this paper, we define a class of voting rules suitable for electing a diverse committee. We show how this class of rules release the issue of compounding excellence and diversity and, further, we provide some axiomatic properties that highlight the behavior of these rules when we aim to select a diverse committee.
