Abstract
Have competitive conditions in the voice services market changed sufficiently to justify lifting most current economic and social regulation on the public switched telephone network (PSTN)? Yes, argues Richard Clarke, describing in detail the ongoing changes in the supply and demand structures of the voice market and their impact on reducing the economic power of the traditional incumbent local exchange carriers (ILECs). Based on this argument, and on evolving technology, Clarke notes that both the PSTN and the voice services it supports are "inexorably going away," to be replaced by new services and technologies, making current regulatory requirements superfluous.

ABSTRACTIn response to increasing costs and reductions in manpower, the Tactical Air Command (TAC) of the USAF experimented with a specialized productivity measurement model known as data envelopment analysis (DEA). A medium‐sized application of DEA was employed by TAC to evaluate the productivity of its seventeen subordinate vehicle maintenance sections over a four‐year period. The application reports gains in productivity and the reactions of the field managers to the use of DEA.
