Abstract

Originating from Porto Alegre Brazil, participatory budgeting (PB) is “a democratic process in which community members decide on how to spend part of a public budget”. It has been used as a way to involve citizens in local decision-making and to improve their understanding of democratic processes. Rutger Bregman posed it as a possible answer to the seven plagues of modern-day democracy, such as a lack of confidence in politicians. Based on recent uses of PB in Groningen, the current research compares multiple voting rules by simulating a PB process. Data was generated to represent voters’ opinions and project costs, allowing for a comparison of the utilitarian, egalitarian and maximal social welfares under various circumstances. Results show that voting systems using ranked list ballots offer significant improvements over the more common one using approval ballots. Furthermore, using truncated lists does not significantly impact performance of ranked list algorithms.
