Adoptions and Orphans in the Early Microcomputer Market
研究了1980年代初微型计算机市场中CP/M操作系统被用户和开发者遗弃、DOS与IBM PC成为主导标准的过程，分析了硬件与软件销售数据的关系，揭示了DOS与CP/M发展背后的不同经济机制。
In this paper we 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 industry standard. We examine the statistical relationship between data that reflects hardware and software sales for the competing platforms. We conclude that the economic processes underlying the development of DOS differed from those underlying CP/M and that many of these differences related to the role of software development.
