在利率期限结构模型中,Lévy过程的自然尺度是多少?
What is the natural scale for a Lévy process in modelling term structure of interest rates?
摘要:
本文利用状态价格密度方法给出了带Lévy跳的无套利利率期限结构模型的例子。通过推广二次高斯模型,发现Lévy过程的密度函数是作为市场状态变量的“自然”尺度。
英文摘要:
This paper gives examples of explicit arbitrage-free term structure models with Lévy jumps via state price density approach. By generalizing quadratic Gaussian models, it is found that the probability density function of a Lévy process is a "natural" scale for the process to be the state variable of a market.
