Time-consistent mean-variance portfolio selection in discrete and continuous time

C Czichowsky - Finance and Stochastics, 2013 - Springer
It is well known that mean-variance portfolio selection is a time-inconsistent optimal control
problem in the sense that it does not satisfy Bellman's optimality principle and therefore the …

Sensitivity analysis of the utility maximisation problem with respect to model perturbations

O Mostovyi, M Sîrbu - Finance and Stochastics, 2019 - Springer
We consider the expected utility maximisation problem and its response to small changes in
the market price of risk in a continuous semimartingale setting. Assuming that the …
