Determining the optimal selling time of cattle:A stochastic dynamic programming approach
decision analysis farm management simulation
2016/11/11
The world meat market demands competitiveness, and optimal livestock replacement decisions can help to achieve this goal. In the article, there is introduced a novel discrete stochastic dynamic progra...
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 ...
Liquidity-adjusted Market Risk Measures with Stochastic Holding Period
Liquidity Risk Random Holding Period Systemic Risk
2010/10/21
Within the context of risk integration, we introduce in risk measurement stochastic holding period (SHP) models. This is done in order to obtain a `liquidity-adjusted risk measure' characterized by t...
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
Valuation equations stochastic volatility models
2010/10/20
We study the valuation partial differential equation for European contingent claims in a general framework of stochastic volatility models. The standard Feynman-Kac theorem cannot be directly applied ...
A maximum principle for forward-backward stochastic Volterra integral equations and applications in finance
Forward-backward stochastic Volterra integral equations Adapted
2010/10/20
This paper formulates and studies a stochastic maximum principle for forward-backward stochastic Volterra integral equations (FBSVIEs in short), while the control area is assumed to be convex. Then a ...
Stochastic Utilities With a Given Optimal Portfolio : Approach by Stochastic Flows
Stochastic Utilities Optimal Portfolio Stochastic Flows
2010/10/20
The paper generalizes the construction by stochastic flows of consistent utilities processes introduced by M. Mrad and N. El Karoui (2010). The market is incomplete and securities are modeled as local...
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...
