This article proposes a semiparametric two-factor term structure model based on a consol rate and the spread between a short rate and the consol rate. The diffusion functions in both the consol rate and spread processes are nonparametrically specified so that the model allows for maximal...

Diffusion functions in term-structure models are measures of uncertainty about future price movements and are directly related to the risk associated with holding financial securities. Correct specification of diffusion functions is crucial in pricing options and other derivative securities. In...
