Jump-Diffusion Processes: Volatility Smile Fitting and Numerical Methods for Option Pricing 总被引:1,自引:0,他引:1
This paper discusses extensions of the implied diffusion approach of Dupire (1994) to asset processes with Poisson jumps.
We show that this extension yields important model improvements, particularly in the dynamics of the implied volatility surface.
The paper derives a forward PIDE (PartialIntegro-Differential Equation) and demonstrates how this equationcan be used to fit
the model to European option prices. For numerical pricing of general contingent claims, we develop an ADI finite difference
method that is shown to be unconditionally stable and, if combined with Fast Fourier Transform methods, computationally efficient.
The paper contains several detailed examples fromthe S&P500 market.

本文利用小波变换频带分析方法,在1991年1月至2007年12月的样本区间研究通货膨胀和证券市场周期波动关联性和条件波动溢出效应。时差相关关系显示,二者周期波动关系出现非一致性.即短周期波动相关性不稳定.中周期波动反向共变.长周期波动高度负相关且通货膨胀先行,并对证券市场的影响具有长期记忆性。条件波动溢出效应检验结果表明.中周期通货膨胀与证券市场条件波动具有双向溢出效应但溢出强度不同.通货膨胀条件波动对证券市场条件波动冲击效应相对较强,而长周期波动只存在通货膨胀对证券市场的单向溢出效应。小波变换频带分析结论.对宏观经济和证券市场稳定发展提供了有针对性的政策启迪。 相似文献

In this article, we use a wavelet-based Granger causality approach to examine the multi-scale causality between saving and growth for China. We show that significant causality runs from saving to growth for most timescales, whereas multi-scale causality from growth to saving is not statistically significant. Our subsample results suggest that economic systems have remarkable effects on the multi-scale causality. Overall, our study provides a novel perspective to deeply explore the relationships between macroeconomic variables. 相似文献

In this paper, we present a nonparametric estimator for ruin probability in the classical risk model with unknown claim size distribution. We construct the estimator by Fourier inversion and kernel density estimation method. Under some conditions imposed on the kernel, bandwidth and claim size density, we present some large sample properties of the estimator. Some simulation studies are also given to show the finite sample performance of the estimator. 相似文献

The aim of the article is to present non-clasical copyrighted algorithm for prediction of time series, presenting macroeconomic indicators and stock market indices. The algorithm is based on artificial neural networks and multi-resolution analysis (the algorithm is based on Daubechies wavelet). However, the main feature of the algorithm, which gives a good quality of the forecasts, is all included in the series analysis division into, a few partial under-series and prediction dependence on a number of other economic series. The algorithm used for the prediction, is copyrighted algorithm, labeled M.H-D in this article. Application of the algorithm was performed on a series presenting WIG 20. The forecast of WIG 20 was conditional on trading the Dow Jones, DAX, Nikkei, Hang Seng, taking into account the sliding time window. As an example application of copyrighted model, the forecast of WIG 20 for a period of two years, one year, six month was appointed. An empirical example is described. It shows that the proposed model can predict index with the scale of two years, one year, a half year and other intervals. Precision of prediction is satisfactory. An average absolute percentage error of each forecast was: 0.0099%---for two-year forecasts WIG 20; 0.0552%--for the annual forecast WIG 20; and 0.1788%---for the six-month forecasts WIG 20. 相似文献
