We compare monopoly profit, consumer surplus, and total welfare associated with three commonly-used tying strategies: no tying, pure tying, and mixed tying. Whereas previous literature focused mainly on profit comparisons, this paper evaluates the relationship between component production costs...

This research paper investigates a duopolistic market characterized by vertical product differentiation. The study considers both product qualities and consumer preferences represented as one-dimensional intervals. The focus is on analyzing the equilibrium in a duopoly game with convex...
