Continuous Equilibrium in Affine and Information-Based Capital Asset Pricing Models
Continuous-time equilibrium exponential utility CAPM affine processes information based asset pricing implied volatility
2012/3/2
We consider a class of generalized capital asset pricing models in continuous time with a finite number of agents and tradable securities. The securities may not be sufficient to span all sources of u...
Path properties and regularity of affine processes on general state spaces
affine processes path properties regularity Markov semimartingales
2011/7/20
We provide a new proof for regularity of affine processes on general state spaces by methods from the theory of Markovian semimartingales. On the way to this result we also show that the definition of...
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...
Pricing and Hedging in Affine Models with Possibility of Default
Pricing Hedging in Affine Models Possibility of Default
2011/1/4
We propose a general class of models for the simultaneous treatment of equity, corporate bonds, government bonds and derivatives. The noise is generated by a general affine Markov process. The framewo...
Long-Term Behaviors and Implied Volatilities in General Affine Diffusion Models
Long-Term Behaviors Implied Volatilities General Affine Diffusion Models
2010/10/22
This paper considers asset price dynamics of which discounted return is modeled by a multi-dimensional affine diffusion process. By analyzing the Riccati system, which is associated with the affine p...
Exact and high order discretization schemes for Wishart processes and their affine extensions
Wishart processes affine processes exact simulation
2010/10/21
This work deals with the simulation of Wishart processes and affine diffusions on positive semidefinite matrices. To do so, we focus on the splitting of the infinitesimal generator, in order to use co...
An Affine Term Structure Model with Auxiliary Stochastic Volatility-Covolatility
Term structure Stochastic volatility Wishart Autoregressive process
2011/4/2
This paper proposes an affine term structure model in a stochastic volatility setting. It provides a useful modeling tool to bridge the two strands of macroeconomic and finance research: the DSGE-VAR ...
Risk Sensitive Investment Management with Affine Processes: a Viscosity Approach
Asset management risk-sensitive stochastic control jump diffusion processes
2010/10/19
In this paper, we extend the jump-diffusion model proposed by Davis and Lleo to include jumps in asset prices as well as valuation factors. The criterion, following earlier work by Bielecki, Pliska, ...
A Type of HJM Based Affine Model: Theory and Empirical Evidence
Affine Term Structure Model HJM Finite Dimensional Realization Linear Realization Theory State Space Framework Macro-economy
2011/4/2
In this paper a type of Heath, Jarrow and Morton (1992) (HJM) based affine model is derived theoretically. This type of affine model is obtained by applying Linear Realization Theory to construct Fini...

Solvable Nonlinear Volatility Diffusion Models Affine Drift
2010/11/1
We present a method for constructing new families of solvable one-dimensional di usions with linear drift and nonlinear di usion coecient functions, whose tran-sition densities are obtainable in anal...
Affine processes on positive semidefinite matrices

2010/11/2
The article provides the mathematical foundation for stochastically continuous affine processes on the cone of positive semidefinite symmetric matrices. This analysis has been motivated by a large and...
Abstract. Bernstein processes are Brownian diffusions that appear in Euclidean Quantum Mechanics. The consideration of the symmetries of the associated Hamilton-Jacobi-Bellman equation allows one to o...

Moment Explosions Long-Term Behavior Affine Stochastic Volatility Models
2010/12/13
We consider a class of asset pricing models, where the risk-neutral joint process of log-price and its stochastic variance is an affine process in the sense of Duffie, Filipovic and Schachermayer [20...

2014/3/13
We develop and implement a technique for closed-form maximum likelihood estimation (MLE) of multifactor affine yield models. We derive closed-form approximations to likelihoods for nineDai and Singlet...
