建立了一个由任何投票机构在多属性或多维方案中进行选择的集体决策模型。与以前的模型不同，突出度问题(即不同维度重要性的变化)被直接考虑：假设每个个体在备选方案中具有词典优先顺序-即，他按照维度对他的重要性(或显著度)的顺序对维度进行排序，仅使用该顺序中的第一个维度在备选方案中进行选择，除非第一个维度对他同样有利。如果是这样，他就使用第二个，以此类推。证明了一些定理，证明了在简单多数规则下存在均衡备选方案(如果没有简单多数偏好的其他备选方案，则P是均衡备选方案)，并讨论了词典假设在各种政治背景下的合理性。
A model is developed of collective decision-making by any voting body choosing among multi-attribute or multi-dimensional alternatives. Unlike previous models, the problem of salience (i.e., variations in the importance of different dimensions) is taken account of directly: each individual is assumed to have a lexicographic preference ordering among alternatives—i.e., he ranks the dimensions in order of their importance (or salience) to him, using only the first dimension in this ordering to choose between alternatives, unless they are equally good for him on the first. If this is so, he uses the second, and so on. Some theorems are proved, establishing the existence of equilibrium alternatives under simple majority rule (P is an equilibrium alternative if there exists no other alternative which a simple majority prefers to P), and the plausibility of the lexicographic assumption in various political contexts is discussed.
