We. Taylor et Jd. Zona, AN ANALYSIS OF THE STATE OF COMPETITION IN LONG-DISTANCE TELEPHONE MARKETS, Journal of regulatory economics, 11(3), 1997, pp. 227-255
In this paper, we examine seven indicia of the effect of regulated com
petition in long-distance telecommunications. The evidence we have exa
mined suggests that regulation or the threat of antitrust intervention
are the major factors which constrain AT&T's prices to small customer
s. We conclude that small customers have yet to enjoy the full benefit
s of competition in long distance.
