Many high technology goods are based on standards that require several essential patents owned by different IP holders. This gives rise to a complements and a double mark-up problem. We compare the welfare effects of two different business strategies dealing with these problems. Vertical...

The literature on vertical integration in markets with regulated upstream prices suggests that the integrated upstream firm might engage in non-price discrimination. Several studies provide policy recommendations derived either from case study approaches or based on theoretical modeling which...

With the development of the Internet and the significant impact it is having, network neutrality regulation has been receiving much attention. An analysis of the relevant literature suggests that the proponents and opponents of network neutrality disagree on the methods of developing the...

In this paper we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under this assumption and those resulting from the traditional example...

In this paper we analyze how the technology used by downstream firms can influence input and output market prices. We show via an example that both these prices increase under a decreasing returns technology while the countrary holds when the technology is constant.

In this paper we analyze how the technology used by downstream firms can influence input and output market prices. We show via an example that both these prices increase under a decreasing returns technology while the contrary holds when the technology is constant.

This paper evaluates the incentive of firms to vertically integrate in a simple 2X2 Bertrand model of two substitutes that are each comprised of two complementary components. It confirms that all prices fall as a result of a vertical merger. Further, we find that, when the composite goods are...
