If consumers have a positive probability to purchase from each firm, then centrally agglomerated and/or symmetric dispersed location equilibria may exist in the 3-firm Hotelling problem. As before, let the product space be the unit interval, [0, 1]. There are two firms, A and B, located at the opposite ends of the segment. 2575.
