Asymptotic utilitarianism in scoring rules
Given a large enough population of voters whose utility functions satisfy certain statistical regularities, we show that voting rules such as the Borda rule, approval voting, and evaluative voting have a very high probability of selecting the social alternative which maximizes the utilitarian social welfare function. We also characterize the speed with which this probability approaches one as t...
متن کاملApproximating Bribery in Scoring Rules
The classic bribery problem is to find a minimal subset of voters who need to change their vote to make some preferred candidate win. We find an approximate solution for this problem for a broad family of scoring rules (which includes Borda and t-approval), in the following sense: if there is a strategy which requires bribing k voters, we efficiently find a strategy which requires bribing at mo...
متن کاملCommittee Scoring Rules
We present and advertise the class of committee scoring rules, recently introduced as multiwinner analogues of single-winner scoring rules. We present a hierarchy of committee scoring rules (which includes all previously studied subclasses of committee scoring rules, as well as two new subclasses) and discuss their axiomatic properties (while focusing on fixed-majority consistency and monotonic...
متن کاملLocal Proper Scoring Rules
Scoring rules assess the quality of probabilistic forecasts, by assigning a numerical score based on the predictive distribution and on the event or value that materializes. A scoring rule is proper if it encourages truthful reporting. It is local of order λ if the score depends on the predictive density only through its value and its derivatives of order up to λ at the observation. Previously,...
متن کاملProper Proxy Scoring Rules
Proper scoring rules can be used to incentivize a forecaster to truthfully report her private beliefs about the probabilities of future events and to evaluate the relative accuracy of forecasters. While standard scoring rules can score forecasts only once the associated events have been resolved, many applications would benefit from instant access to proper scores. In forecast aggregation, for ...
