Rank Maximal Equal Contribution: a Probabilistic Social Choice Function

چکیده

When aggregating preferences of agents via voting, two desirable goals are to incentivize agents to participate in the voting process and then identify outcomes that are Pareto efficient. We consider participation as formalized by Brandl, Brandt, and Hofbauer (2015) based on the stochastic dominance (SD) relation. We formulate a new rule called RMEC (Rank Maximal Equal Contribution) that is polynomial-time computable, ex post efficient and satisfies the strongest notion of participation. It also satisfies many other desirable fairness properties. The rule suggests a general approach to achieving very strong participation, ex post efficiency and fairness.

Consistent Probabilistic Social Choice

Two fundamental axioms in social choice theory are consistency with respect to a variable electorate and consistency with respect to components of similar alternatives. In the context of traditional non-probabilistic social choice, these axioms are incompatible with each other. We show that in the context of probabilistic social choice, these axioms uniquely characterize a function proposed by ...

Fully sincere voting

In a general social choice framework where the requirement of strategyproofness may not be sensible, we call a social choice rule fully sincere if it never gives any individual an incentive to vote for a less-preferred alternative over a more-preferred one and provides an incentive to vote for an alternative if and only if it is preferred to the default option that would result from abstaining....

Maximal domain for strategy-proof probabilistic rules in economies with one public good

We consider the problem of choosing a level of provision of public good on an interval of the real line among a group of agents. A probabilistic rule chooses a probability distribution over the interval to each preference profile. We investigate strategy-proof probabilistic rules in the case where distributions are compared based on stochastic dominance relation. First, on a “minimally rich dom...
