One-factor short-rate modelsss .. Modeling directly such dynamics is very convenient since all fundamental quantities (rates and bonds) are readily defined, by no-arbitrage arguments, as the expectation of a functional of the process .. Indeed, the existence of a risk-neutral measure implies that the arbitrage-free price at ti

Cases of Calibration of the LIBOR Market Modelata. We study several cases based on different instantaneous-volatility parameterizations. We will also point out a particular parameterization allowing for a closed-form-formulas calibration to swaption volatilities and establishing a one to one correspondence between swaption volatilities and LFM

Local-Volatility Modelsderlying asset, Dupire (1994, 1997) has derived a candidate LVM that is compatible with the given implied-volatility surface. Balland and Hughston (2000) and Brigo and Mercurio (2003), see Section 10.13, have addressed a similar issue in the interest-rate case, where a single caplet maturity is avai

Uncertain-Parameter Modelsin the financial literature as an easy-to-implement alternative to SVMs. UVMs are based on the assumption that the asset’s volatility is stochastic in the simplest possible way, modelled by a random variable rather than a diffusion process. Precisely, the dynamics of a general forward rate . under t
