近几十年来,有效风险管理的重要性从未如此重要。然而,风险度量(例如风险价值)的估计准确性仍然是一个挑战。在本文中,我们提出了一种新颖的非参数方法来有效提高风险估计的准确性,因为我们的方法可以避免模型错误指定并充分挖掘资产收益中包含的尾部信息。将非参数风险价值计量嵌入风险对冲模型中,以提高风险管理的有效性。模拟表明,我们的新方法在准确性方面优于现有方法。实证结果表明,改进的估计有助于更有效地管理天气敏感市场的风险。
The importance of effective risk management has never been greater in recent decades. However, the estimate accuracy of risk measures, such as Value-at-Risk, remains a challenge. In this paper, we propose a novel non-parametric method to efficiently enhance the accuracy of risk estimation as our method can avoid model misspecification and fully explore the tail information contained in asset returns. The non-parametric Value-at-Risk measure is embedded into a risk hedge model to increase the effectiveness of risk management. Simulations show that our new method outperforms existing methods in terms of accuracy. Empirical findings support that the improved estimation is helpful for more effectively managing risk in weather-sensitive markets.
