交叉持股下的无套利定价

No-arbitrage pricing under cross-ownership

Tom Fischer

摘要:

我们推广默顿的资产评估方法,以系统的多个金融公司的股权和负债的交叉所有权是存在的。负债可能包括债务和衍生工具,其优先级可能不同。我们推导出无套利条件下的股票价格和回收索赔的方程。证明了一个存在性结果和唯一性结果。例子和算法的同时计算的所有无套利价格提供。讨论了外部债权对公司集团资本结构不相关性的影响,以及财务杠杆和交叉持股引起的系统性风险。

英文摘要:

We generalize Merton's asset valuation approach to systems of multiple financial firms where cross-ownership of equities and liabilities is present. The liabilities, which may include debts and derivatives, can be of differing seniority. We derive equations for the prices of equities and recovery claims under no-arbitrage. An existence result and a uniqueness result are proven. Examples and an algorithm for the simultaneous calculation of all no-arbitrage prices are provided. A result on capital structure irrelevance for groups of firms regarding externally held claims is discussed, as well as financial leverage and systemic risk caused by cross-ownership.
