An Econometric Model of the Yield Curve with Macroeconomic Jump Effects
Macroeconomic Jump Effects Yield Curve
2015/7/23
This paper develops an arbitrage-free time-series model of yields in continuous time
that incorporates central bank policy. Policy-related events, such as FOMC meetings
and releases of macroeconomic...
Analyzing the Spectrum of Asset Returns: Jump and Volatility Components in High Frequency Data
Analyzing the Spectrum Asset Returns Jump Volatility Components High Frequency Data
2014/3/13
This paper reports some of the recent developments in the econometric analysis of semimartingales estimated using high frequency financial returns. It describes a simple yet powerful methodology to de...
Computing Quantiles in Regime-Switching Jump-Diffusions with Application to Optimal Risk Management: a Fourier Transform Approach
regime switching jump-diffusion models Value at Risk risk management Fourier transform methods.
2012/9/14
In this paper we consider the problem of calculating the quantiles of a risky position,the dynamic of which is described as a continuous time regime-switching jump-diffusion, by using Fourier Transfor...
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 ...
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...
Price Jump Prediction in Limit Order Book
Price Jump Prediction Limit Order Book Trading and Market Microstructure
2012/4/28
A limit order book provides information on available limit order prices and their volumes. Based on these quantities, we give an empirical result on the relationship between the bid-ask liquidity bala...
Multilevel Monte Carlo method for jump-diffusion SDEs
Multilevel Monte Carlo method jump-diffusion SDEs expected payoff jump rates
2011/7/4
We investigate the extension of the multilevel Monte Carlo path
simulation method to jump-diffusion SDEs. We consider models with
finite rate activity , using a jump-adapted discretisation in which ...
Utility based pricing and hedging of jump diffusion processes with a view to applications
pricing hedging of jump diffusion processes marginal optimal hedge
2011/7/4
We discuss utility based pricing and hedging of jump di usion pro-
cesses with emphasis on the practical applicability of the framework. We
point out two diculties that seem to limit this applicabi...
Density Approximations for Multivariate Affine Jump-Diffusion Processes
Affine Processes Asymptotic Expansion Density Approximation
2011/7/25
Abstract: We introduce closed-form transition density expansions for multivariate affine jump-diffusion processes. The expansions rely on a general approximation theory which we develop in weighted Hi...
Jump-Diffusion Risk-Sensitive Asset Management II: Jump-Diffusion Factor Model
Asset management risk-sensitive stochastic control jump diffusion processes Poisson point processes L´ evy processes HJB PIDE policy improvement parabolic PDE classical solutions viscosity solutions.
2011/3/23
In this article we extend earlier work on the jump-diffusion risk-sensitive asset management problem [SIAM J. Fin. Math. (2011) 22-54] by allowing jumps in both the factor process and the asset prices...
Precautionary Measures for Credit Risk Management in Jump Models
Credit risk management Double exponential jump diffusion Spectrally negative L´ evy processes
2010/10/19
Sustaining efficiency and stability by properly controlling the equity to asset ratio is one of the most important and difficult challenges in bank management. Due to unexpected and abrupt decline of...
On the Penalisation Error for American Options in a Jump Model
American Option Jump-Di usion Model Penalty Method
2010/10/21
We consider the pricing of American options in a model where the underlying asset is assumed to follow a jump diffusion process. The option value can be expressed as the solution to a variational ineq...
Credit risk premia and quadratic BSDEs with a single jump
Backward Stochastic Differential Equations (BSDE) defaultable contingent claims progressive enlargement of filtrations utility maximization
2010/11/1
This paper is concerned with the determination of credit risk premia of defaultable contingent claims by means of indifference valuation principles.Assuming exponential utility preferences we derive r...
A Loan Portfolio Model Subject to Random Liabilities and Systemic Jump Risk
A Loan Portfolio Model Random Liabilities Systemic Jump Risk
2010/10/20
We extend the Vasi\v{c}ek loan portfolio model to a setting where liabilities fluctuate randomly and asset values may be subject to systemic jump risk. We derive the probability distribution of the pe...
Two-sided estimates for stock price distribution densities in jump-diffusion models
Stochastic volatility models Jump-diffusion models Stock
2010/10/20
We consider uncorrelated Stein-Stein, Heston, and Hull-White models and their perturbations by compound Poisson processes with jump amplitudes distributed according to a double exponential law. Simila...
