通胀预期量度在以通胀预期为导向的货币政策中的意义重大。本文利用卡尔曼滤波法将离散时间两因子无套利广义高斯仿射模型运用于我国银行间债券市场,第一次从中国国债收益率曲线中分解出金融市场的中长期通胀预期L。将L与居民通胀预期和经济学家通胀预期比较,发现从事前看,L优于经济学家通胀预期,稍逊于居民通胀预期;从事后看,L优于居民通胀预期,稍逊于经济学家通胀预期。综合看,L作为金融市场形成的、高频的、反映中长期通胀的预期指数,对货币政策制定具有现实的参考意义。 相似文献

The standard method for valuing a European option on a bond portfolio is developed by Jamshidian. He shows that under certain circumstances the payoff from a bond option can be expressed as a portfolio of payoffs on discount bond options, allowing the option to be valued as a portfolio of options. A limitation of this approach is that it cannot be applied to non‐Markovian interest rate processes. This paper develops a method for the valuation of a European option on a bond portfolio that can be applied to both Markovian and non‐Markovian interest rate processes. 相似文献

Differences between yields on comparable‐maturity U.S. Treasury nominal and real debt, the so‐called breakeven inflation (BEI) rates, are widely used indicators of inflation expectations. However, better measures of inflation expectations could be obtained by subtracting inflation risk premiums (IRP) from the BEI rates. We provide such decompositions using an affine arbitrage‐free model of the term structure that captures the pricing of both nominal and real Treasury securities. Our empirical results suggest that long‐term inflation expectations have been well anchored over the past few years, and IRP, although volatile, have been close to zero on average. 相似文献

Many real-world financial contracts have some sort of minimum rate of return guarantee included. One class of these guarantees is so-called relative guarantees, i.e., guarantees where the minimum guaranteed rate of return is given as a function of the stochastic return on a reference portfolio. These guarantees are the topic of this paper. We analyse a wide range of different functional specifications for the minimum guaranteed rate of return, hereunder both so-called maturity and multi-period guarantees. Several closed form solutions are presented. 相似文献
