The results presented in the previous section tend to confirm the hypothesis that committee assignments shape the pattern of corporate PAC contributions. This note corroborates existing research on corporate PACs at a significantly lower level of aggregation than the samples on which existing research has been conducted. Further, because a nonparametric test was used (rather than the more standard regressional analysis), these results should increase our confidence that the essential institutions of government affect, and engender responses by, economic agents.
