Decentralized Portfolio Management

We use a mean-variance model to analyze the problem of decentralized portfolio management. We find the solution for the optimal portfolio allocation for a head trader operating in n different markets, which is called the optimal centralized portfolio. However, as there are many traders specialized in different markets, the solution to the problem of optimal decentralized allocation should be di...

Collaborative Expert Portfolio Management

We consider the task of assigning experts from a portfolio of specialists in order to solve a set of tasks. We apply a Bayesian model which combines collaborative filtering with a feature-based description of tasks and experts to yield a general framework for managing a portfolio of experts. The model learns an embedding of tasks and problems into a latent space in which affinity is measured by...

Mortality Portfolio Risk Management

In this paper, we offer a new method of managing the risk of unexpected changes in mortality underlying annuities and life insurance. This method maximizes the insurer’s profit margin, subject to constraints on its downside mortality risk. We also show how to determine bounds on mortality margins when information on the moments of the distributions is known. We provide numerical examples to ill...

This situation can also arise when the investor is in fact a group, the members of which have different utilities and/or different...
