We characterize the positional social preference correspondences (spc) satisfying the qualified majority property for any given majority threshold. We also characterize the positional spcs satisfying the minimal majority property. We next evaluate the probability that the Borda, the plurality and the antiplurality spcs fulfil the two aforementioned properties under the Impartial and Anonymous Culture assumption in the presence of three and four alternatives for various sizes of the society. Our results show that the Borda spc is the positional spc which better behaves in relation with the qualified majority principle and the minimal majority principle.

位置社会偏好对应的多数性质

我们描述了满足任何给定多数阈值的合格多数属性的位置社会偏好对应关系 ( spc )。我们还描述了满足最小多数属性的位置spc。接下来,我们评估了在存在三种和四种不同规模社会的替代方案的情况下,在公正和匿名文化假设下,博尔达、多元和反多元spc满足上述两个特性的可能性。我们的结果表明,Borda spc是位置spc,它在符合条件多数原则和最小多数原则方面表现得更好。
