An Econometric Analysis of Telecom Competition, Privatization, and Regulation in Africa and Latin America
研究了1984至1997年间30个非洲和拉美国家中私有化、竞争和监管对电信业绩的影响，发现竞争和独立监管下的私有化能提升电信服务，但仅私有化效果有限。
This paper explores the effects of privatization, competition, and regulation on telecommunications performance in 30 African and Latin American countries from 1984 through 1997. Fixed‐effects regressions reveal that competition??measured by mobile operators not owned by the incumbent??is correlated with increases in the per capita number of mainlines, payphones, and connection capacity, and with decreases in the price of local calls. Privatization combined with an independent regulator is positively correlated with telecom performance measures. Privatization alone, however, is associated with few benefits, and is negatively correlated with connection capacity.
