This paper considers a firm's choice between a "divisional structure" and a "functional structure." It shows that an increase in the number of projects which the firm can adopt creates a managerial overload, which favors the divisional structure.

We show that the Bertrand oligopoly model with cost asymmetries may admit multiple Nash equilibria when firms hold passive ownership stakes in each other. The equilibrium price may be as high as the monopoly price of the most efficient firm.
