高管腐败与股东监控的经济理论分析

现代股份制公司的股东与管理层之间会形成一种典型的委托代理关系。企业股东往往不具备专业的企业管理能力，他们并不会直接参与公司的管理决策。为了投资能够获得与其承担的风险相适应的回报，股东们常常将公司的运营权委托给具备专业知识和经验的职业经理人。这种安排使得公司决策过程更为高效，但也引入了代理问题，代理人可能会利用其掌握的控制权和信息优势追求私人利益，进行腐败行为，损害委托人的利益和公司总价值。因此，股东需要监控企业管理人的腐败行为，保护自身权益。

为了研究这一问题，本文构建了一个连续时间委托代理模型，假定代理人的腐败行为不仅会导致企业现金流的流失，还会对企业现金流增长产生负面影响。代理人在进行腐败行为时会付出一定的腐败成本，其腐败成本受委托人监控力度的影响。在模型求解上，本文利用倒向递推的方法分别求得代理人、委托人与债权人的价值函数。本还还利用MATLAB进行数值模拟，分析了不同情形下代理人腐败水平与委托人监控水平的变化以及道德风险下的企业最优资本结构问题。数值结果表明，企业债息的发放有利于缓解代理问题，在最优资本结构下，委托人与代理人最优策略受代理人薪酬激励、企业廉洁度以及企业税率的影响。

本文的核心贡献在于将股东的内部监控与高管腐败成本联系在一起。通过构建理论模型，我们研究了代理人腐败情形下委托人的最优监控问题与企业的最优资本结构问题，为公司治理以及企业融资决策提供参考。
