题目: 依赖于时间变化波动率的多因子HJM 模型的利率衍生
报告摘要: We investigate the partial differential equation (PDE) for pricing interest derivatives in the multi-factor Cheyette Model, that involves time-dependent volatility functions with a special structure. The high dimensional parabolic PDE that results is solved numerically via a modified sparse grid approach, that turns out to be accurate and efficient. In addition we study the corresponding Monte Carlo simulation, which is fast since the distribution of the state variables can be calculated explicitly. The results obtained from both methodologies are compared to the analytical solution existing for bonds and caplets.
