In the context of decentralized portfolio optimization, understanding how to distribute a fixed budget among decentralized intermediaries is a relevant investment problem, that has been recently introduced in the mathematical economics literature. While existing contributions focus on incentive...

The importance of investment advisers to the financial well-being of their clients cannot be overstated. Individuals and institutions entrust trillions of dollars to investment advisers to manage on their behalf. This paper discusses and explains fiduciary principles in investment advice....

Existing literature regarding the natural hedge potential that arises from combining liabilities with different sensitivities focuses on the optimal liability mix, but does not address the question whether and how changes in the liability mix can be obtained. In the absence of a well-functioning...

The conversations surrounding corporate social responsibility ("CSR") in international investments often involve framing the discussions from the FDI lens. This Article aims to add another dimension to the discussion: the consideration of the sovereign-driven portfolio investment (in contrast to...

This paper is about the corporate structure, the organizational structure, and the financial structure of firms, and how they relate to each other. We show that separation of ownership and control may arise as a response to overload costs, although it involves agency costs, and that...

We propose a multi-stage stochastic trading cost model in optimal portfolio selection. This strategy captures uncertainty in implicit transaction costs incurred by an investor during initial trading and in subsequent rebalancing of the portfolio. We assume that implicit costs are stochastic as...

As in continuous time, the nontrading region (NTR) in a mean-variance model with fixed, proportional, and quadratic trading costs is a singleton only for pure quadratic costs. Utility loss from costs is approximately proportional at small cost levels, and approximately constant at large cost...

We remove the technical assumption $\gamma>0$ imposed by Dai et. al. who consider the optimal investment and consumption decision of a CRRA investor facing proportional transaction costs and finite time horizon. As a by-product, we obtain an estimate on the optimal consumption

This paper focuses on cross-sectional equity momentum patterns by modeling a stock's price path as the interaction between a long-term growth component and a number of fluctuating price components that oscillate around the long-term trend at various distinct frequencies. Using this...
