نویسندگان
چکیده
We consider numerical approximations to the quantile hedging price of a European claim in nonlinear market with Markovian dynamics. study an equivalent stochastic target problem conditional probability success as new state variable, addition asset value process. propose based on piecewise constant policy time stepping coupled novel finite difference schemes. prove convergence monotone case combining backward differential equation arguments Barles and Jakobsen Souganidis approaches for PDEs. The difficulties compared classical setting consist construction schemes under degeneracy due perfectly correlated joint process, unboundedness control effect boundaries variable analysis. extend method class nonmonotone using higher order interpolation linear drivers. In section, we illustrate performance our by considering example financial imperfections, show that standard scheme produces financially counterintuitive solutions.

15 صفحه اولQuantile hedging
In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling to spend that much, and who is ready to use a hedging strategy which succeeds with high probability.
متن کاملQuantile hedging for equity-linked contracts
We consider an equity-linked contract whose payoff depends on the lifetime of policy holder and the stock price. We provide best strategy for an insurance company assuming the limited capital for the hedging.
متن کاملA numerical scheme for space-time fractional advection-dispersion equation
In this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. We utilize spectral-collocation method combining with a product integration technique in order to discretize the terms involving spatial fractional order derivatives that leads to a simple evaluation of the related terms. By using Bernstein polynomial basis, the problem is transformed in...
متن کاملA numerical scheme for solving nonlinear backward parabolic problems
In this paper a nonlinear backward parabolic problem in one dimensional space is considered. Using a suitable iterative algorithm, the problem is converted to a linear backward parabolic problem. For the corresponding problem, the backward finite differences method with suitable grid size is applied. It is shown that if the coefficients satisfy some special conditions, th...
