Casadesus-Masanell, Ramon, and David B. Yoffie. "Wintel: Cooperation and Conflict." Management Science 53, no. 4 (April 2007): pp. 584-598. Abstract

We study competitive interactions between Intel and Microsoft, two producers of complementary products. In a system of complements, like the PC, the value of the final product depends on how well the different components work together. This, in turn, depends on the firms' investment in complementary R\&D. We ask whether Intel and Microsoft will want to cooperate and make the final product as valuable as possible. Contrary to the popular view that two tight complements will generally have well aligned incentives, we demonstrate that natural conflicts emerge over pricing, the timing of new product releases, and who captures the greatest value at different phases of product generations.

Casadesus-Masanell, Ramon, Barry Nalebuff, and David B. Yoffie. "Competing Complements." Harvard Business School Working Paper, No. 09-009, July 2008. Abstract

In Cournot's model of complements, the producers of A and B are both monopolists. This paper extends Cournot's model to allow for competition between complements on one side of the market. Consider two complements, A and B, where the A + B bundle is valuable only when purchased together. Good A is supplied by a monopolist (e.g., Microsoft) and there is competition in the B goods from vertically differentiated suppliers (e.g., Intel and AMD). In this simple game, there may not be a pure-strategy equilibria. In the standard case where marginal costs are weakly positive, there is no pure strategy where the lower quality B firm obtains positive market share. We also consider the case where A has negative marginal costs, as would arise when A can expect to make upgrade sales to an installed base. When profits from the installed base are sufficiently large, a pure strategy equilibrium exists with two B firms active in the market. Although there is competition in the complement market, the monopoly Firm A may earn lower profits in this environment. Consequently, A may prefer to accept lower future profits in order to interact with a monopolist complement in B.

Casadesus-Masanell, Ramon, and David B. Yoffie. "Wintel: Cooperation or Conflict." Harvard Business School Working Paper, No. 05-083, July 2005. Abstract

We study the incentives of complementors (producers of complementary products) to cooperate vs. compete and how these interact. In a system of complements, like the PC, the value of the final product depends on how well the different components work together. This, in turn, depends on the firms� investment in complementary R&D. We ask whether profit maximizing complementors will fully cooperate to make the final product as valuable as possible. Contrary to the popular view that two tight complements will generally have well aligned incentives, we demonstrate that natural conflicts emerge over pricing, the timing of investments, and who captures the greatest value at different phases of product generations.
