Contributions to Federal Election Campaigns by Government Contractors
构建理论模型分析企业是否设立政治行动委员会及捐款金额，并用226家政府承包商数据检验，发现企业规模、政府销售强度和市场结构影响其政治捐款决策。
The author develops a theoretical model that determines whether or not a firm sponsors a political action committee and, if it does, the quantity of funds that the political action committee will disburse. The firm is assumed to face supply and demand schedules for political action committee receipts, whose positions depend on attributes of the firm, such as firm size, government-sales intensity, and market structure. Two related equations derived from the theoretical model--a probit equation for political action committee sponsorship and a disbursements equation--are estimated using pooled data on 226 government (primarily defense) contracting firms during the 1979-80 and 1981-82 election cycles.
