对赌协议设计及定价

作为市场经济中最具活力的参与者，初创企业在经济长期发展中扮演着关键的角色。然而，由于信息不对称，融资难题一直是初创企业发展的主要障碍。风险投资机构作为重要的资金来源，不仅提供资金支持，还在市场拓展、资源整合等方面提供增值服务，对于支持初创企业的成长至关重要。在我国风险投资市场中，对赌协议作为一种特殊的契约形式得到广泛应用，但对于对赌协议的设计和定价问题，从契约理论和衍生品定价角度的系统研究较为缺乏。

为了弥补这一不足，本文运用金融契约理论、经济博弈论方法、随机分析技术和衍生品定价原理，针对股权补偿型对赌协议，在离散和连续模型下进行探讨，计算不同对赌目标和补偿方式下的契约价值，并提出委托代理问题以求解最优契约，结合数值分析探究其经济学意义。

研究结果表明，在内生增长率较低的项目中，风险投资机构应着重保护其持有的股份，而在内生增长率较高的项目中，则应给予创业者更多的股份激励。当双向对赌协议的最优解是单向对赌情形时，风险投资机构应持有较低的初始股权比例，创业者能力较低，项目质量较高且风险较低。对于固定股权转让协议，风险投资机构需要通过股权再分配机制在项目内生增长率达到特定临界点之前激励创业者，并在后续阶段专注于在高价值项目中获取更高的份额。总的来说，制订股权补偿型对赌协议时，风险投资机构不仅要关注项目的内生增长率，还要利用股权再分配机制来规避项目收益不确定性。这项研究为我国风险投资市场中对赌协议的实践提供了重要的参考依据。
