In this paper, the authors examine the development of the microcomputer market in the early 1980s. CP/M, a widely-adopted operating system, was orphaned by the user and the development communities. A new operating system, DOS, and a new hardware platform, the IBM PC, became the predominant...

In this paper, the authors examine the software provision decision of software firms. The provision decision by software firms determines the value and, hence, the market share of competing hardware technologies. The authors show how the provision decision by software firms determines whether...

In Israel, area cable television licenses were auctioned sequentially. This paper provides evidence that there were interdependencies among many of the franchises and that subscriber fees for the interdependent franchises decreased over time in this auction. Copyright 1997 by Blackwell...

The authors study the introduction of a new product in a market with network externalities. There is a common presumption that such markets exhibit excess inertia, i.e., that they are biased toward existing products. In contrast, the authors provide conditions under which equilibrium involves...

Converters, emulators, or adapters can often make one technology partially compatible with another. The authors analyze the equilibrium market adoption of otherwise incompatible technologies when such converters are available and the incentives to provide them. While market outcomes without...

Although network effects can make predation more likely to succeed, we find that the leading anti-predation rules may lower or raise efficiency and consumer welfare in network markets. We find that: (a) the extensive debates about the 'correct' measure of cost on which to base price floors are...
