The literature on differentiated products only considers symmetric cross-price effects and shows that the profit ordering of firms in a sequential set-up is uni-directional. This paper shows that uni-directional profit ordering breaks down under asymmetric product differentiation. Above a unique cross-price effect level the follower's profit exceeds that of the leader. The reverse is true below this level. This result holds for both substitutes and complements.
