Complementarity, Coordination and Compatibility: The Role of Fixed Costs in the Economics of Systems

Abstract:
We analyze industry equilibrium and incentive to compatibility when goods produced by different producers generate utility only when consumed as component parts of a system. We assume the presence of two systems, each composed of some basic component and a set of differentiated complementary products. The combination of complementarity between the two components of the system and of fixed costs in the production of the complementary product results in a form of network effect. We focus on the role played by the size of the fixed costs in the production of the complementary products in determining the size of this system effect and, by this means, the structure and types of equilibria that may be observed: monopolistic or duopolistic, symmetric or asymmetric. We also highlight the consequence of the same fixed costs for the private and social incentives to render the systems compatible.

EconWPA began as a conversation between Bob Parks and Larry Blume on January 28, 1993. I located Paul Ginsparg's archive (then xxx.lanl.gov) and he graciously installed his software on a Sun Sparc system which was supporting the department of economics email and computation. EconWPA began accepting papers July 1, 1993 and had ftp, email, gopher and web interfaces. The web interface for submissions was engineered into existence in July 1995. A complete and catastrophic machine failure in 1999 caused the loss of EconWPA's email new paper announcment service at which time there were over 15,000 subscriptions with over 8,000 unique email addresses.

In 2005, Arts and Sciences commandeered the computing services that I had provided to the Department of Economics since 1987. Some might say that the department was sold out, others would (erroneously) claim that centralization is efficient, and still others would claim that I have few marketing skills.

I was told that I could keep operating EconWPA (as well as many other services including rfe.wustl.edu, barnett.wustl.edu, and three RePEc servers) but I would receive no support (hardware, software, or anthing else) and (as had been the case) no compensation. At that point, given the apparent low valuation of my activities by the department, and university, it made no sense for me to continue operating EconWPA or other services.

Thanks to all who have supported EconWPA in the past.
