Proportional Committee Elections with Positive and Negative Votes
TL;DR
This research introduces a novel approach to committee elections that incorporates both positive and negative votes, enhancing proportional representation. Two interpretations of negative voting are proposed, each leading to distinct fairness guarantees for candidate selection.
✦ Why It Matters
Consider implementing negative voting mechanisms in your next election system to enhance voter representation.
Key Takeaways
- Explore voting systems that include negative votes for better representation.
- Implement fairness guarantees for both approvals and disapprovals.
- Utilize Phragmén's rule or PAV for proportional elections.
- Consider the implications of voter disapproval in candidate selection.
How It Works
The study proposes two distinct interpretations of negative votes. In the first, preventing the election of disapproved candidates is prioritized equally with electing approved candidates.
In the second interpretation, approvals and disapprovals are treated independently, each with its own fairness criteria. This dual approach allows for a more comprehensive understanding of proportionality in elections.
