Is It Whom You Know or What You Know? An Empirical Assessment of the Lobbying Process
研究美国联邦游说中，游说者的人脉关系与专业知识哪个更重要，发现人脉带来更稳定的金钱回报，但专家也能影响对立党派议员。
Do lobbyists provide issue-specific information to members of Congress? Or do they provide special interests access to politicians? We present evidence to assess the role of issue expertise versus connections in the US Federal lobbying process and illustrate how both are at work. In support of the connections view, we show that lobbyists follow politicians they were initially connected to when those politicians switch to new committee assignments. In support of the expertise view, we show that there is a group of experts that even politicians of opposite political affiliation listen to. However, we find a more consistent monetary premium for connections than expertise.
