Second Order Multiscale Stochastic Volatility Asymptotics: Stochastic Terminal Layer Analysis & Calibration
Second Order Multiscale Stochastic Volatility Asymptotics Stochastic Terminal Layer Analysis Calibration
2012/9/14
Multiscale stochastic volatility models have been developed as an efficient way to capture the principle effects on derivative pricing and portfolio optimization ofrandomly varying volatility. The rec...
Calibration of optimal execution of financial transactions in the presence of transient market impact
Calibration financial transactions market
2012/9/14
Trading large volumes of a nancial asset in order driven markets requires the use of algorithmic execution dividing the volume in many transactions in order to minimize costs due to market impact. A ...
Calibration of Chaotic Models for Interest Rates
Positive interest rate models Wiener chaos model calibration
2011/7/4
In this paper we calibrate chaotic models for interest rates to market data using a
polynomial{exponential parametrization for the chaos coecients. We identify a subclass of one{
variable models th...
Calibration of structural and reduced-form recovery models
Credit risk Loss distribution Reduced–form models Structural models Value at Risk Expected Tail Loss Stochastic processes
2011/3/23
In recent years research on credit risk modelling has mainly focused on default probabilities. Recovery rates are usually modelled independently, quite often they are even assumed constant.
Credit Calibration with Structural Models: The Lehman case and Equity Swaps under Counterparty Risk
Credit Default Swaps StructuralModels Black Cox Model, Calibration
2010/11/3
In this paper we develop structural first passage models (AT1P and SBTV)with time-varying volatility and characterized by high tractability, moving from the original work of Brigo and Tarenghi (2004, ...
Regime Switching Volatility Calibration by the Baum-Welch Method
Regime switching stochastic volatility calibration Hamilton filter Baum-Welch
2010/10/29
Regime switching volatility models provide a tractable method of modelling stochastic volatility. Currently the most popular method of regime switching calibration is the Hamilton filter. We propose u...
In this work we develop a tractable structural model with analytical default probabilities depending on a random default barrier and possibly random volatil-ity ideally associated with a scenario base...
Credit Default Swap Calibration and Equity Swap Valuation under Counterparty Risk with a Tractable Structural Model

2010/11/3
In this paper we develop a tractable structural model with analytical default probabilities depending on some dynamics parameters, and we show how to cal-ibrate the model using a chosen number of Cred...
