Introduction

How campaign contributions influence the behavior of members of Congress is an important question with theoretical and normative implications for our understanding of congressional decision making, interest-group influence, and participation in the less frequently studied nonvoting forms of political behavior and how economic inequalities may translate into inequalities in the system of representation. To answer this question, social scientists (mostly in political science, economics, and sociology) have first tried to understand what interest groups are attempting to accomplish with their donations by studying which types of individuals and interests are most likely to contribute and the pattern of their donations. They have also directly examined the relationship between contributions and various types of behavior. Though most campaign contributions actually come from individual citizens, there is relatively little research into the motivations of individual donors or the effect that individual donations may have on behavior. This likely reflects that, rightly or wrongly, critics are less troubled by individual contributions than those from wealthy “special interests.” Thus this article focuses mostly on the intentions underlying and the effect of contributions from organized interests, which are studied more often.

General Overviews

These works (or parts of these works) provide good overviews of the literature on the effect of campaign contributions on behavior. Baumgartner and Leech 1998 provides a table summarizing the results of dozens of studies of the effect of campaign contributions on congressional behavior. Roscoe and Jenkins 2005 reviews the literature and conducts a meta-analysis of the effect of campaign contributions. Ginsberg and Green 1986 discusses the various pathways by which money may influence members of Congress. Sabato 1985 provides a good, early qualitative understanding of how political action committees (PACs) operate. Sorauf 1984 and Sorauf 1992 also provide a descriptive understanding of PACs and campaign contributing more generally and raise some important normative concerns. Stratmann 2005 provides a good literature review of many questions of concern for students of campaign contributions. Milyo, et al. 2000 argues that campaign contributions do not constitute a great deal of money compared to other expenditures and are thus perhaps not much to worry about.

    Roscoe and Jenkins present a literature review and meta-analysis of the findings of a large number of campaign contribution studies. They state that approximately one-third of studies find some effect of contributions on voting, and in their meta-analysis they find support for this relationship.
