摘要:
本文主要研究了在HJM模型框架下对流动性风险的刻画。通过对HJM模型的介绍,把流动性利差作为期限结构直接进行建模,给出流动性利差所满足的动态方程,以此推导出带有流动性风险的债券的价格。同时还通过市场数据,对模型参数、流动性利差和远期利率曲线进行了估计和拟合。
This paper studies the liquidity risk under the HJM framework. Through the introduction of the HJM model, we consider liquidity as a term structure and give the liquidity spread dynamic equation directly. Finally, we obtain the dynamic equation of the price of the liquidity-risk bond. Moreover, we estimate and fit the model parameters, liquidity spread and forward rate curve by the market data.
