Pricing joint claims on an asset and its realized variance under stochastic volatility models
Volatility derivatives stochastic volatility models partial differential equations parabolic equations target volatility option.
2012/9/14
In a stochastic volatility framework, we find a general pricing equation for the class of payoffs depending on the terminal value of a market asset and its final quadratic variation. This allows a pri...
We attempt to unveil the fine structure of volatility feedback effects in the context of general quadratic autoregressive (QARCH) models, which assume that today’s volatility can be expressed as a gen...
Stochastic Volatility with Heterogeneous Time Scales
Stochastic Volatility Long Memory Generalized Methods of Moments Econo-physics
2012/9/13
Agents' heterogeneity has been recognized as a driver mechanism for the persistence of nancial volatility. We focus on the multiplicity of investment strategies' horizons;we embed this concept in a c...
Approximating stochastic volatility by recombinant trees
American options stochastic volatility Heston model correlated random walk
2012/6/5
A general method to construct recombinant tree approximations for stochastic volatility models is developed and applied to the Heston model for stock price dynamics. In this application, the resulting...
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...
The fractional volatility model: No-arbitrage, leverage and completeness
Fractional noise Arbitrage Incomplete market
2012/6/4
Based on a criterion of mathematical simplicity and consistency with empirical market data, a stochastic volatility model has been obtained with the volatility process driven by fractional noise. Depe...
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 ...
Libor model with expiry-wise stochastic volatility and displacement
displaced Libor models stochastic volatility calibration to capstrike maturity matrix swaption pricing
2012/4/28
We develop a multi-factor stochastic volatility Libor model with displacement, where each individual forward Libor is driven by its own square-root stochastic volatility process. The main advantage of...
Maximum likelihood approach for several stochastic volatility models
Maximum likelihood approach several stochastic volatility models Computational Finance
2012/4/28
Volatility measures the amplitude of price fluctuations. Despite it is one of the most important quantities in finance, volatility is not directly observable. Here we apply a maximum likelihood method...
Realized Wavelet Jump-GARCH model: Can wavelet decomposition of volatility improve its forecasting?
wavelet decomposition jumps volatility forecasting Realized GARCH
2012/4/28
In this paper, we propose a forecasting model for volatility based on its decomposition to several investment horizons and jumps. As a forecasting tool, we utilize Realized GARCH framework of Hansen e...
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 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 ...
COUNTERPARTY RISK FOR CREDIT DEFAULT SWAPS:: IMPACT OF SPREAD VOLATILITY AND DEFAULT CORRELATION
contingent credit default swaps copula functions Counterparty risk Credit Default Swaps
2011/8/30
We consider counterparty risk for Credit Default Swaps (CDS) in presence of correlation between default of the counterparty and default of the CDS reference credit. Our approach is innovative in that,...
Treasury Bond Volatility and Uncertainty about Monetary Policy
macroeconomic factors monetary policy survey data
2011/8/21
We show that dispersion-based uncertainty about the future course of monetary policy is the single most important determinant of Treasury bond volatility across all maturities. The link between Treasu...
