The Condorcet Efficiency of a voting rule is defined as the conditional probability that the voting rule elects the Pairwise Majority Rule Winner (PMRW), given that a PMRW exists. Five simple voting rules are considered in this paper: Plurality Rule, Negative Plurality Rule, Borda Rule,...

This paper has examined the relationship between social homogeneity measured by σ(p)=p <Subscript>1</Subscript> <Superscript>2</Superscript> + ... + p <Subscript>6</Subscript> <Superscript>2</Superscript> and the likelihood of Condorcet's paradox. Attention was restricted to three-candidate elections. It was shown first that the most general restriction on p vectors that produces a definite...</superscript></subscript></superscript></subscript>

The Borda Compromise states that, if one has to choose among five popular voting rules that are not Condorcet consistent, one should always give preference to the Borda rule over the four other rules. We assess the theoretical as well as the empirical support for the Borda Compromise. We find...
