Social influences on corporate political donations in Britain.

It is argued that institutional features of the British state create collective action problems for the mobilization of corporations as donors to the Conservative Party. Social factors are necessary for overcoming these problems. Using social network analyses, the effect that interlocking directorates have on 250 large British corporations' decisions to donate are analysed. Instead of the central mobilizing factor being diffuse inner circle mechanisms positively influencing the decision to make a donation, the results show that more particularistic mechanisms such as information bias and control are equally important.
