Three papers consider the effect of divestiture on the research and development capacity of Bell Telephone. The first paper, "Forecasts of the Impact of Divestiture on Bell Telephone Laboratories: An Assessment" (David C. Mowery), discusses the operation of Bell Telephone Laboratories (BTL) prior to divestiture in 1984 and reviews forecasts of the impact of divestiture on BTL, in order to compare and contrast the predictions of these two approaches to the analysis of the organization of industrial research. A 35-item bibliography is provided. The second paper, "The Impact of Divestiture on R&D in the Bell System" (A. Michael Noll) (abstract only), discusses the changes in the structure of research and development brought about by the Bell Telephone divestiture, including both the creation of a "new" facility, "Bellcore," to satisfy the research and development needs of the newly separated Bell operating companies, and the simultaneous creation of separate internal research and development capabilities by these companies. The third paper, "The Implications of Diverstiture and Regulatory Policies for Research, Development and Innovation by the Regional Bell Holding Companies" (Robert G. Harris), examines the effects of divestiture on research and development, especially as they contribute to the development of technological innovations. A list of 53 references is provided.
