Do arbitrage-free prices come from utility maximization?
arbitrage-free prices come from utility maximization
2012/9/14
In this paper we ask whether arbitrage-free prices are obtained by utility maximization. This is found to be true for any given investor, provided that one considers the marginal utility-based prices ...
Robust utility maximization for Levy processes:Penalization and solvability
Convex risk measures duality robust utility Levy processes.
2012/9/14
In this paper the robust utility maximization problem for a market model based on Levy processes is analyzed. The interplay between the formof the utility function and the penalization function requir...
Stability of the exponential utility maximization problem with respect to preferences
utility maximization exponential utility stability semimartingales utility-based prices
2012/6/5
This paper studies stability of the exponential utility maximization when there are small variations on agent's utility. Two settings are studied. First, in a general semimartingale model where random...
The Stability of the Constrained Utility Maximization Problem - A BSDE Approach
Model Formulation. Continuity of the Optimizers
2011/7/20
This article studies the sensitivity of the power utility maximization problem with respect to the investor’s relative risk aversion, the statistical probability measure, the investment constraints an...
BSDEs in Utility Maximization with BMO Market Price of Risk
BSDEs BMO Market Price of Risk
2011/7/20
This article studies quadratic semimartingale BSDEs arising in power utility maximization
when the market price of risk is of BMO type. In a Brownian setting we provide a necessary and sucient condi...
Stability of exponential utility maximization with respect to market perturbations
Stability exponential utility market perturbations
2011/7/19
Abstract. We investigate the continuity of expected exponential utility maximization with respect to perturbation of the Sharpe ratio of markets. By focusing only on continuity, we impose weaker regul...

2011/7/4
This paper studies the problem of optimal investment with CRRA (constant, relative risk aversion)
preferences, subject to dynamic risk constraints on trading strategies. The market model considered

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...
Power Utility Maximization in Discrete-Time and Continuous-Time Exponential Levy Models

Consider power utility maximization of terminal wealth in a 1-dimensional continuous-time exponential Levy model with finite time horizon.
On utility maximization under convex portfolio constraints
utility-maximization semimartingale financial market predictable convex-set-valued processes
2011/3/23
We consider a utility-maximization problem in a general semimartingale financial market, subject to constraints on the number of shares held in each risky asset. These constraints are modeled by predi...

In this paper we extend the stability results of [4]}. Our utility maximization problem is defined as an essential supremum of conditional expectations of the terminal values of wealth processes, con...

2010/10/22
We maximize the expected utility of terminal wealth in an incomplete market where there are cone constraints on the investor's portfolio process and the utility function is not assumed to be strictly ...
Smooth Value Functions for a Class of Nonsmooth Utility Maximization Problems
nonsmooth utility maximization classical solution to HJB equation smooth
2010/10/20
In this paper we prove that there exists a smooth classical solution to the HJB equation for a large class of constrained problems with utility functions that are not necessarily differentiable or st...
Risk Aversion Asymptotics for Power Utility Maximization

2010/10/19
We consider the economic problem of optimal consumption and investment with power utility. We study the optimal strategy as the relative risk aversion tends to infinity or to one. The convergence of ...
Utility Maximization of an Indivisible Market with Transaction Costs
Utility optimization indivisible market transaction cost
2010/10/19
This work takes up the challenges of utility maximization problem when the market is indivisible and the transaction costs are included. First there is a so-called solvency region given by the minimum...
