风险投资中存在风险投资家现金索取权和对项目的控制权分别规定并普遍使用可转换优先股的特殊现象.在不完全合同的框架下,对比了债权融资、股权融资以及可转换优先股融资下,风险投资家对项目控制权实施的效率.通过模型分析发现:债权融资下风险投资家事后会过度控制项目;股权融资下风险投资家对项目控制不足;而可转换优先股则使得风险投资家事后实施社会有效的控制强度.这表明在风险投资中,可转换优先股分配的现金索取权是风险投资家事前取得控制权的有效实施机制.
From the perspective of incomplete contract, we study the efficiency of the venture capitalist' s con- trolling the venture in the pure-debt financing or the pure-equity financing or the convertible preferred equity circumstances. We find that the convertible preferred equity financing dominates both the pure-debt financing and the pure-equity financing method, and the convertible preferred equity financing implements the first-best efficiency.
