摘要翻译:
利用谱分析、奇异摄动理论和正则摄动理论等工具,我们提出了一种解析计算衍生资产近似价格的系统方法。衍生资产的收益可能是路径依赖的。此外,衍生品的潜在过程可能表现出杀戮(即跳转到违约)以及合并的局部/非局部随机波动性。波动的非局部成分是多尺度的,从某种意义上说,它是由一个快变和一个慢变因素驱动的。我们的建模框架的灵活性与我们的方法的简单性形成了对比。我们将导数定价问题归结为求解单个特征值方程的问题。一旦特征值方程解出,一个导数的近似价格就可以公式化地计算出来。为了说明我们的方法,我们计算了三种衍生资产的近似价格:违约股票的香草期权、非违约股票的路径依赖期权和短期利率模型中的债券。

英文摘要:
Using tools from spectral analysis, singular and regular perturbation theory, we develop a systematic method for analytically computing the approximate price of a derivative-asset. The payoff of the derivative-asset may be path-dependent. Additionally, the process underlying the derivative may exhibit killing (i.e. jump to default) as well as combined local/nonlocal stochastic volatility. The nonlocal component of volatility is multiscale, in the sense that it is driven by one fast-varying and one slow-varying factor. The flexibility of our modeling framework is contrasted by the simplicity of our method. We reduce the derivative pricing problem to that of solving a single eigenvalue equation. Once the eigenvalue equation is solved, the approximate price of a derivative can be calculated formulaically. To illustrate our method, we calculate the approximate price of three derivative-assets: a vanilla option on a defaultable stock, a path-dependent option on a non-defaultable stock, and a bond in a short-rate model.
