WebRemark 5.6 (Hull–White model). The Hull–White model is also called the extended Vasicek model or the G++ model and can be considered, more generally, with the constants k and σ replaced by deterministic functions. Theorem 5.7 (Short rate in the Hull–White model). Let 0 ≤ s ≤ t ≤ T.The short rate in the Hull–White model is given by WebThe Hull-White one-factor model is specified using the zero curve, alpha, and sigma parameters. Specifically, the HullWhite1F model is defined using the following equations: d r = [ θ ( t) − a ( t) r] d t + σ ( t) d W where: dr is the change in the short-term interest rate over a small interval. r is the short-term interest rate.

Web21 okt. 2024 · 无套利模型的思路是：首先估计出利率期限结构，以这个期限结构作为输入变量去预测后续的期限结构，然后为利率衍生品进行定价。无套利模型一般并不是以刻画利率期限结构为目的，因此也不需要考虑额外的风险因素。代表性的模型有许多，比如HL、HW、BK、BDT等等，现今很多基于利率衍生品定价方面的研究基本都是无套利模型。 … In financial mathematics, the Hull–White model is a model of future interest rates. In its most generic formulation, it belongs to the class of no-arbitrage models that are able to fit today's term structure of interest rates. It is relatively straightforward to translate the mathematical description of the evolution of future interest rates onto a tree or lattice and so interest rate derivatives such as bermudan swaptions can be valued in the model. poplar pediatrics
