Optimal Stabilization Rules in a Stochastic Model of Investment with Gestation Lags.
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...
Utility Maximization, Risk Aversion, and Stochastic Dominance
Utility maximization, risk aversion, stochastic dominance
2011/7/22
Consider an investor trading dynamically to maximize expected utility from terminal wealth. Our aim is to study the dependence between her risk aversion and the distribution of the optimal terminal pa...
Stochastic impulse control on optimal execution with price impact and transaction cost
Price impact impulse control dynamic programming vis-cosity solutions
2011/3/30
We study a single risky financial asset model subject to price impact and transaction cost over an finite time horizon. An investor needs to execute a long position in the asset affecting the price of...
Arbitrage Opportunities in Misspecified Stochastic volatility Models
stochastic volatility model misspecification volatility arbitrage
2010/10/18
There is vast empirical evidence that given a set of assumptions on the real-world dynamics of an asset, the European options on this asset are not efficiently priced in options markets, giving rise t...
On dependence of the implied volatility on returns for stochastic volatility models
stochastic volatility the Heston model
2010/10/21
We study the dependence of volatility on the stock price in the stochastic volatility framework on the example of the Heston model.To be more specific, we consider the conditional expectation of vari...
Asymptotic analysis for stochastic volatility: Edgeworth expansion
Asymptotic analysis stochastic volatility Edgeworth expansion
2010/10/19
The validity of an approximation formula for European option prices under a general stochastic volatility model is proved in the light of the Edgeworth expansion for ergodic diffusions. The asymptotic...
Asymptotic error distribution for approximation of a stochastic integral with respect to continuous semimartingale by Riemann sum with general stochastic partition is studied. Effective discretization...
An Exact Connection between two Solvable SDEs and a Non Linear Utility Stochastic PDEs
forward utility performance criteria horizon-unbiased utility
2010/10/20
The paper proposes a new approach to consistent stochastic utilities, also called forward dynamic utility, recently introduced by M. Musiela and T. Zariphopoulou. These utilities satisfy a property of...
Convex duality in stochastic programming and mathematical finance
Convex duality stochastic programming mathematical finance
2010/10/20
This paper proposes a general duality framework for the problem of minimizing a convex integral functional over a space of stochastic processes adapted to a given filtration. The framework unifies ma...
Bounds on Stock Price probability distributions in Local-Stochastic Volatility models
Law of the spot price local-stochastic volatility moment explosion
2010/10/20
We show that in a large class of stochastic volatility models with additional skew-functions (local-stochastic volatility models) the tails of the cumulative distribution of the log-returns behave as...
A note on evolutionary stochastic portfolio optimization and probabilistic constraints
evolutionary stochastic portfolio optimization probabilistic constraints
2010/10/18
In this note, we extend an evolutionary stochastic portfolio optimization framework to include probabilistic constraints. Both the stochastic programming-based modeling environment as well as the evol...
Extra-Dimensional Approach to Option Pricing and Stochastic Volatility
Extra-Dimensional Option Pricing Stochastic Volatility
2010/10/18
The generalized 5D Black-Scholes differential equation with stochastic volatility is derived. The projections of the stochastic evolutions associated with the random variables from an enlarged space o...
The valuation process that economic agents undergo for investments with uncertain payoff typically depends on their statistical views on possible future outcomes, their attitudes toward risk, and, of ...
Diagnostics of Rational Expectation Financial Bubbles with Stochastic Mean-Reverting Termination Times
bubble super-exponential regime rational expectation critical time finite-time-singularity
2010/11/2
We propose two rational expectation models of transient financial bubbles with heterogeneous
arbitrageurs and positive feedbacks leading to self-reinforcing transient stochastic
faster-than-exponent...
