Horizontal Equity
澄清了横向公平原则的含义和规范内容，重新定义了“平等者”及其“平等对待”，为设计和评估再分配政策提供了更恰当的定义。
The principle of horizontal equity (HE) is considered as a basic principle to follow in order to design and evaluate a redistributive policy. However, the theoretical debate has not yet clarified what exactly horizontal equity is. In this paper we aim to clarify the meaning of the principle of HE and its normative content. In particular, we establish the true status of the two fundaments of the principle of HE, defining what is meant by ‘equals’ and then treating these ‘equals’‘equally’. Our analysis brings forth a new and more appropriate definition of the principle of HE.
