Proportional Participatory Budgeting
Since Participatory Budgeting (PB) has arisen as an interesting application of social choice, I wanted to share one of our key papers on the topic. The paper was written in 2019 with Barton Lee and was published at AAAI 2021. It presents axioms for the problem of PB under ordinal preferences over projects. The input format of weak ordinal is more general and expressive than approval ballots that only allows voters to express a subset of projects. In particular, we propose a polynomial-time algorithm called PB-EAR that returns PB outcomes that satisfy a natural and desirable proportional representation axiom called Inclusion PSC (IPSC).
