On the specification of the drift and diffusion functions for continuous-time models of the spot interest rate
Hurn, Stanley & Lindsay, Kenneth A. (2002) On the specification of the drift and diffusion functions for continuous-time models of the spot interest rate. Oxford Bulletin of Economics and Statistics, 64(5), pp. 547-564.
his paper explores the specification of drift and diffusion functions for continuous-time short-term interest rate models. Various forms for the drift and diffusion of 7-day Eurodollar rates are proposed and then estimated by discrete maximum-likelihood. The results suggest that a nonparametric specification of drift and volatility in terms of orthogonal polynomial expansions is effective in eliminating problems of parameter identification encountered previously. Some evidence is found to support the claim that the drift of the short term interest rate is nonlinear.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
