Is private campaign finance a good thing?: estimates of the potential informational benefits
研究用美国数据检验私人捐款能否为选民提供候选人有效性的信息，发现总捐款额是弱正向信号，小额捐款是强正向信号，大额捐款是负向信号，组织捐款是正向信号。
What would happen if the current U.S. campaign finance system, mostly based on private donations, were replaced by a public funding scheme of the same magnitude? Some argue that public funding would deprive voters of useful information, but this can only be true if private donations are somehow targeted to better candidates. In this paper, we ask what voters can learn about the effectiveness of a legislator from the amount and pattern of contributions received during the campaign. We find that the total amount that a candidate receives is a positive, but weak, predictor of that candidate's effectiveness. Small contributions provide a strong and positive signal of effectiveness, while large contributions are a negative signal of effectiveness. Contributions from organizations also provide a positive signal, while contributions from individuals, parties, and candidates themselves do not.
