Three papers consider various aspects of the AT&T (American Telephone and Telegraph Company) court-ordered divestiture. The first paper, "InterLATA Toll Alternatives for the Bell Regional Holding Companies" (Elizabeth A. La Blanc, Ann M. Wolf, and Richard M. Wolf), examines six options available to the RHCs (regional holding companies) for permitting them to enter into the interLATA or inter-state (long distance) provision of telephone service. The second paper, "Forces Affecting Telephone Bills, Post Divestiture" (Elizabeth La Blanc and Edgar Gentle) projects residential telephone rates for 1990 and considers the factors affecting them, including competition, deregulation, and pricing. It also compares post-divestiture 1990 telephone bills with what they would have been if divestiture had not taken place and bills had simply risen with inflation. The third paper, "Pre- and Post-Divestiture Purchasing Practiced by the Bell Operating Companies" (Gordon T. Ray), compares the RHC purchasing practices since the AT&T divestiture with those of AT&T before the divestiture, noting that the RHC's expansion into fields beyond the traditional telephone network has resulted in the purchase of products and systems representing a wide variety of technologies from a diverse group of manufacturers. It is concluded that RHC purchasing practices have adjusted, and will continue to adjust, to these changes. (Author/EW)
