Price volatility spillovers among agricultural commodity and crude oil markets: Evidence from the range-based estimator
agricultural commodity market financial crisis of 2008–2009 futures markets historical price volatility intra-day data
2015/6/8
The paper examines the price volatility spillovers among the crude oil, soybeans, corn, wheat, and sugar futures markets over the period 1/1/2006–11/29/2013. We separately investigate the periods of t...
Volatility and stabilization of the price of coffee and cocoa in C魌e d扞voire
farm gate price international price price fluctuation buffer stock cocoa and coffee markets
2014/2/24
The aim of this paper was to study the coffee and cocoa price volatility in C魌e d扞voire and to understand the mechanism of price stabilization. Thus, this paper shows that the international prices and...
New solvable stochastic volatility models for pricing volatility derivatives
New solvable stochastic volatility models pricing volatility derivatives Pricing of Securities
2012/6/5
Classical solvable stochastic volatility models (SVM) use a CEV process for instantaneous variance where the CEV parameter $\gamma$ takes just few values: 0 - the Ornstein-Uhlenbeck process, 1/2 - the...
Exponential Levy models with stochastic volatility and stochastic jump-intensity
spectral theory normal operator Levy process stochastic volatility stochastic jump-intensity
2012/6/4
We consider the problem of valuing a European option written on an asset whose dynamics are described by an exponential L\'evy-type model. Both the volatility and jump-intensity of the L\'evy process ...
Arbitrage-free SVI volatility surfaces
Arbitrage-free SVI volatility surfaces Pricing of Securities
2012/4/28
In this article, we show how to calibrate the widely-used SVI parameterization of the implied volatility surface in such a way as to guarantee the absence of static arbitrage. In particular, we exhibi...
Local Volatility Pricing Models for Long-dated FX Derivatives
Local volatility Stochastic volatility Foreign Exchange Stochastic interest rates Calibration
2012/4/28
We study the local volatility function in the Foreign Exchange market where both domestic and foreign interest rates are stochastic. This model is suitable to price long-dated FX derivatives. We deriv...
Pricing Variable Annuity Guarantees in a Local Volatility framework
Pricing Variable Annuity Guarantees Local Volatility framework Pricing of Securities
2012/4/28
In this paper, we study the price of Variable Annuity Guarantees, especially of Guaranteed Annuity Options (GAO) and Guaranteed Minimum Income Benefit (GMIB), and this in the settings of a derivative ...
Modeling and forecasting volatility in global food commodity prices
volatility forecast fat-tail distribution food commodities
2014/2/27
To capture the volatility in the global food commodity prices, we employed two competing models, the thin tailed the normal distribution, and the fat-tailed Student t-distribution models. Results base...
Arbitrage hedging strategy and one more explanation of the volatility smile
step-like contrast structure semi-linear parabolic equation arbitrage option hedging strategy volatility smile
2011/3/23
We present an explicit hedging strategy, which enables to prove arbitrageness of market incorporating at least two assets depending on the same random factor. The implied Black-Scholes volatility, com...
On Calibrating Stochastic Volatility Models with time-dependent Parameters
Calibrating Stochastic Volatility Models time-dependent Parameters
2010/10/22
We consider stochastic volatility models using piecewise constant parameters. We suggest a hybrid optimization algorithm for fitting the models to a volatility surface and provide some numerical resu...
Density quantization method in the optimal portfolio choice with partial observation of stochastic volatility
Optimal portfolio partial observation ltering density
2010/10/21
Computational aspects of the optimal consumption and investment with the partially observed stochastic volatility of the asset prices are considered. The new quantization approach to filtering - dens...
Analytical and Numerical Approaches to Pricing the Path-Dependent Options with Stochastic Volatility
Analytical Numerical Pricing Path-Dependent Options Stochastic Volatility
2010/10/21
In this paper new analytical and numerical approaches to valuating path-dependent options of European type have been developed. The model of stochastic volatility as a basic model has been chosen. Fo...
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 contribution to the systematics of stochastic volatility models
fluctuations econophysics stochastic differential equations
2010/10/21
We compare systematically several classes of stochastic volatility models of stock market fluctuations. We show that the long-time return distribution is either Gaussian or develops a power-law tail,...
Valuation equations for stochastic volatility models
