Ordinal versus cardinal voting rules: A mechanism design approach

نویسنده

  • Semin Kim
چکیده

We consider the performance and incentive compatibility of voting rules in a Bayesian environment with independent private values and at least three alternatives. It is shown that every (ex-ante) Pareto efficient ordinal rule among neutral rules is incentive compatible under a symmetry assumption on alternatives. Furthermore, we prove that there exists an incentive compatible cardinal rule which achieves higher utilitarian social welfare than any ordinal rule when the distribution of every agent’s values is identical.

Truthful Approximations to Range Voting

We consider the fundamental mechanism design problem of approximate social welfare maximization under general cardinal preferences on a finite number of alternatives and without money. The wellknown range voting scheme can be thought of as a non-truthful mechanism for exact social welfare maximization in this setting. With m being the number of alternatives, we exhibit a randomized truthfulin-e...

The Case for Utilitarian Voting

Utilitarian voting (UV) is defined in this paper as any voting rule that allows the voter to rank all of the alternatives by means of the scores permitted under a given voting scale. Specific UV rules that have been proposed are approval voting, allowing the scores 0, 1; range voting, allowing all numbers in an interval as scores; evaluative voting, allowing the scores -1, 0, 1. The paper deals...

Claude Hillinger: Utilitarian Collective Choice and Voting

In his seminal Social Choice and Individual Values, Kenneth Arrow stated that his theory applies to voting. Many voting theorists have been convinced that, on account of Arrow’s theorem, all voting methods must be seriously flawed. Arrow’s theory is strictly ordinal, the cardinal aggregation of preferences being explicitly rejected. In this paper I point out that all voting methods are cardinal...

Equilibrium and effectiveness of two-parameter scoring rules

We study a cardinal model of voting with three alternatives where voters’ von Neumann Morgenstern utilities are private information. We consider voting protocols given by two-parameter scoring rules, as introduced by Myerson (2002). For these voting rules, we show that all symmetric Bayes Nash equilibria are sincere, and have a very specific form. These equilibria are unique for a wide range of...
