英文摘要:
We introduce a class of interest rate models, called the $\\alpha$-CIR model, which gives a natural extension of the standard CIR model by adopting the $\\alpha$-stable L{\\\'e}vy process and preserving the branching property. This model allows to describe in a unified and parsimonious way several recent observations on the sovereign bond market such as the persistency of low interest rate together with the presence of large jumps at local extent. We emphasize on a general integral representation of the model by using random fields, with which we establish the link to the CBI processes and the affine models. Finally we analyze the jump behaviors and in particular the large jumps, and we provide numerical illustrations.

中文摘要:
我们引入了一类利率模型,称为$\\alpha$-CIR模型,它通过采用$\\alpha$-稳定的L{e}vy过程并保持分支性质,对标准CIR模型进行了自然扩展。该模型允许以统一且简洁的方式描述最近对主权债券市场的几项观察,例如低利率的持续性以及局部范围内的大幅跳跃。我们强调通过使用随机场对模型进行一般的积分表示,利用随机场建立与CBI过程和仿射模型的联系。最后,我们分析了跳跃行为,特别是大跳跃,并提供了数值说明。
