Abstract

This paper analyzes the effects of regulation, privatization, and competition on the telecommunications performance in 40 Latin American, African, and Arab countries from 1992 through 2010. By using difference-in-Difference with control variables and propensity score matching techniques, our study reveals that regulation is positively correlated with tariffs and quality. However; competition has no effect on tariffs. This result allows us to suspect the presence of collusion between competitors.
