Strong Condorcet efficiency of scoring rules

In an election, an alternative is said to be a strong Condorcet winner when more than 50% of the voters rank this alternative first in their preferenc e orders. The strong Condorcet efficiency of a voting rule is defined as th e probability of electing the strong Condorcet winner, given that such an a lternative exists. In this paper, we provide some analytical representation s for the strong Condorcet efficiency of some specific scoring rules in thr ee-alternative elections. (C) 2000 Elsevier Science S.A.
