报告摘要: We propose an efficient numerical method to calculate the Value-at-Risk for variable annuities under exponential L ?evy models. In the proposed approach, the prob bility density of the net liabilities is approximated using the theory of frames and Riesz bases. The key element of the numerical method is a new algorithm for calculating the integral of the exponential L ?evy process, approximated by a discrete sum whose expectation coincides with the expected value of the desired integral. Numerical experiments on the application of the developed method for the Black-Scholes and CGMY models clearly demonstrate its high accuracy and speed.
