Campaign Contributions and House Voting on Sugar and Dairy Legislation
研究糖业和乳制品生产商的政治行动委员会（PAC）的竞选捐款如何影响美国众议院议员对相关立法的投票，发现捐款与投票的关联主要源于捐款帮助了意识形态倾向支持该行业的议员当选，而非直接购买选票。
Abstract In this article, I explore the determinants of campaign contributions by sugar and dairy producer PACs and their role in voting on sugar and dairy legislation in the U.S. House of Representatives. Contributions and voting may be linked in two ways. First, a group can buy votes from a legislator who would otherwise not support the group. Second, it can help elect a legislator who is ideologically predisposed to support the group. Results indicate that the first linkage is not important. Virtually the entire observed association between money and voting is a result of the second linkage.
