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...

Consider using the simple moving average (MA) rule of Gartley (1935) to determine when to buy stocks, and when to sell them and switch to the risk-free rate. In comparison, how might the performance be affected if the frequency is changed to the use of MA calculations? The empirical results show...

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...

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....

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

More than 20 years ago, Professor Herbert Hax (1989) derived the basic principles for measuring performance from the two conflicting demands that the ascertainable profit in a given period should be bound up with the effect of management decisions, and should also not be able to be manipulated....
