Recovery of Time-Dependent Parameters of a Black-Scholes-Type Equation: An Inverse Stieltjes Moment Approach

Marianito R. Rodrigo, Rogemar S. Mamon
2007 Journal of Applied Mathematics  
We show that the problem of recovering the time-dependent parameters of an equation of Black-Scholes type can be formulated as an inverse Stieltjes moment problem.  ...  An application to the problem of implied volatility calculation in the case when the model parameters are time varying is provided and results of numerical simulations are presented.  ...  Acknowledgment The first author wishes to acknowledge the support of the Asociaci ón Mexicana de Cultura, A.C.  ...

Information-Based Jumps, Asymmetry and Dependence in Financial Modelling

We focus on a special type of GLPs that we call Archimedean Survival Processes (ASPs). The terminal value of an ASP has an [Symbol appears here.  ...  The terminal values of GLPs have generalised multivariate Liouville distributions, and GLPs can model a wide spectrum of information-driven dependence structures between assets.  ...  To construct a GLP, we start with a master LRB {L t } 0≤t≤un where L un has marginal law ν for u n ∈ N + and n ≥ 2. We assume that ν has no continuous singular part (see Sato, 1999) .  ...
