Competing for Endorsements
研究利益集团领袖通过背书向成员传递信息时，政党如何争夺背书，以及政策结果偏向特殊利益的程度和均衡的规范性质。
Endorsements are a simple language for communication between interest-group leaders and group members. The members, who share policy concerns, may not perfectly understand where their interests lie on certain issues. If their leaders cannot fully explain the issues, they can convey some information by endorsing a candidate or party. When interest groups endorse legislative contenders, the candidates may compete for backing. Policies may favor special interests at the expense of the general public. We examine the conditions under which parties compete for endorsements, the extent to which policy outcomes are skewed, and the normative properties of the political equilibria.
