Abstract

ABSTRACT The D'Hondt method is the most popular proportional apportionment procedure, as well as one of the oldest. Despite this, the method is not fully understood, with serious normative and empirical implications for democratic representation. This paper provides insights into the D'Hondt method through a generalization that is based on a finite mixture model, extends to situations with missing data (e.g. imperfect records), and applies to allocation problems outside of elections. The generalization disproves several widely accepted beliefs, clarifying that the method maximizes the fraction of exactly proportionally represented votes, and providing intuitive measures of overall and party-level disproportionality. The crucial insights of this interpretation are easily communicated in natural language without any mathematical formalisms, which makes it particularly useful for lay audiences and civic education. I illustrate these features with the 1999–2014 British European Parliament elections.

对D’Hondt方法的再思考
D'Hondt法是最流行的比例分摊法,也是最古老的比例分摊法之一。尽管如此,这种方法仍未得到充分理解,对民主代表制具有严重的规范和经验意义。本文通过基于有限混合模型的泛化提供了对D'Hondt方法的见解,扩展到数据缺失的情况(例如,不完整的记录),并适用于选举之外的分配问题。这一概括否定了几个被广泛接受的信念,澄清了该方法最大化了完全按比例代表的选票的比例,并提供了总体和政党层面不比例的直观衡量标准。这种解释的关键见解很容易用自然语言传达,不需要任何数学形式,这使得它对外行观众和公民教育特别有用。我用1999年至2014年英国欧洲议会选举来说明这些特点。
