Abstract：We study potential alliance formation among three competing firms with asymmetric capacity: one large firm has ample capacity, and two small firms have limited capacity. Each firm can either operate independently or form an alliance with another firm.  Due to antitrust laws, an alliance of all three firms is not permitted. We first derive and compare equilibrium profits for different alliance structures in the base model where the size of loyal buyers for different firms is symmetric. By considering a standard equilibrium concept, we find that either no alliance will be formed or the large firm will form a ''mixed'' alliance with a small firm under conditions pertaining to the sizes of each firm's capacity and loyal buyers. We explain how the equilibrium alliance structure is driven by the ''price effect'' and the ''demand effect''. We also extend our base model to the case when the large firm has more loyal buyers than the small ones, and show that our structural results remain the same even though a ''small'' alliance with two small firms can emerge as the dominant alliance structure in some occasions.
