Why Do Political Action Committees Give Money to Candidates? Campaign Contributions, Policy Choices, and Election Outcomes

This paper examines political action committees' motivations for giving campaign contributions to candidates for political office. First, the paper estimates the effect of campaign contributions received by candidates on the outcomes of the 1996 elections to the U.S. House of Representatives. Next, the paper uses a Congressional Quarterly survey of candidates' policy positions to determine the impact of contributions on the policy stances adopted by the candidates. The empirical results suggest that political action committees donate campaign funds to challengers in order to affect the outcome of the election. Campaign contributions received by challengers have a large impact on the election outcome but do not affect the challengers' policy stances on any of the five issues examined in this paper. Campaign contributions to incumbents do not raise their chances of election, however, and affect their policy decisions on only one issue. Some evidence is presented that PAC contributions to incumbents may be given primarily in order to secure unobservable services for the political action committees.

"Campaign Contributions, Policy Decisions, and Election Outcomes: A Study of the Effects of Campaign Finance Reform"

Proposals for campaign finance reform are essentially based on the belief that political influence can be bought with financial donations to a candidate's campaign. But do contributions really influence the decisions of legislators once they are in office? In this brief, Christopher Magee examines the link between campaign donations and legislators' actions. His results suggest that political action committees donate campaign funds to challengers in order to affect the outcome of the election by increasing the challenger's chances of winning. These contributions have a large effect on the election outcome but do not seem to affect challengers' policy stances. In contrast, campaign contributions to incumbents do not raise their chances of being reelected and seem to be given with the hope of gaining influence.

Tracing technological development trajectories: A genetic knowledge persistence-based main path approach

The aim of this paper is to propose a new method to identify main paths in a technological domain using patent citations. Previous approaches for using main path analysis have greatly improved our understanding of actual technological trajectories but nonetheless have some limitations. They have high potential to miss some dominant patents from the identified main paths; nonetheless, the high network complexity of their main paths makes qualitative tracing of trajectories problematic. The proposed method searches backward and forward paths from the high-persistence patents which are identified based on a standard genetic knowledge persistence algorithm. We tested the new method by applying it to the desalination and the solar photovoltaic domains and compared the results to output from the same domains using a prior method. The empirical results show that the proposed method overcomes the aforementioned drawbacks defining main paths that are almost 10x less complex while containing more of the relevant important knowledge than the main path networks defined by the existing method.Comment: 20 pages, 7 figure
