Dynamic mean–variance optimization problems with deterministic information
TL;DR: In this article, the problems of mean-variance hedging and portfolio selection under restricted information were solved in a setting where the underlying price process S is a semima-constraint.

Approximating Random Variables by Stochastic Integrals
TL;DR: In this paper, the authors consider the problem of approximating a given random variable by a stochastic integral with respect to the standard space of semimartingales, and provide sufficient conditions for the existence of such a decomposition.

On the Minimal Martingale Measure and the Foellmer- Schweizer Decomposition
TL;DR: In this article, the authors provide characterizations of the minimal martingale measure P associated to a given d-dimensional semimartingale X. In each case, P is shown to be the unique solution of an optimization problem where one minimizes a certain functional over a suitable class of signed local martingales for X.
Journal ArticleDOI
From structural assumptions to a link between assets and interest rates
TL;DR: The authors derived a link between assets and interest rates in a standard multi-asset diffusion economy from two structural assumptions, one on the volatility and the other on the short rate function.
