关于风险价值(VaR)的全局最小化

On the Global Minimization of the Value-at-Risk

Jong-Shi Pang, Sven Leyffer

AI总结:

本文针对金融风险分析中的VaR非凸最小化问题,将其转化为带线性互补约束的线性规划,提出上下界方法以计算全局最优VaR,并用数值示例验证。

摘要:

本文考虑了金融风险分析中出现的风险价值(VaR)的非凸最小化问题。通过将该问题视为一个具有线性互补约束的特殊线性规划(更准确地说,是一个双层线性规划),我们为最小VaR开发了上下界,并展示了如何将组合边界程序用于计算该值的全局最优解。文中提供了一个数值示例来说明该方法。

英文摘要:

In this paper, we consider the nonconvex minimization problem of the value-at-risk (VaR) that arises from financial risk analysis. By considering this problem as a special linear program with linear complementarity constraints (a bilevel linear program to be more precise), we develop upper and lower bounds for the minimum VaR and show how the combined bounding procedures can be used to compute the latter value to global optimality. A numerical example is provided to illustrate the methodology.
