Small-time asymptotics for fast mean-reverting stochastic volatility models
Small-time asymptotics fast mean-reverting stochastic volatility models
2010/10/21
In this paper, we study stochastic volatility models in regimes where the maturity is small but large compared to the mean-reversion time of the stochastic volatility factor. The problem falls in the...
A Fast Mean-Reverting Correction to Heston's Stochastic Volatility Model
Stochastic volatility Heston model fast mean-reversion
2010/10/21
We propose a multi-scale stochastic volatility model in which a fast mean-reverting factor of volatility is built on top of the Heston stochastic volatility model. A singular pertubative expansion is...
Spectral Decomposition of Option Prices in Fast Mean-Reverting Stochastic Volatility Models
Spectral Decomposition Option Prices Fast Mean-Reverting Stochastic Volatility Models
2010/10/21
Using spectral decomposition techniques and singular perturbation theory, we develop a systematic method to approximate the prices of a variety of options in a fast mean-reverting stochastic volatilit...
RAW MATERIAL PRICES, WAGES, AND PROFITABILITY IN CHINA’S INDUSTRY—HOW WAS PROFITABILITY MAINTAINED WHEN INPUT PRICES AND WAGES INCREASED SO FAST?
China profitability commodity price raw material wage
