We follow two hypotheses: that improvement and growth of ICT make domestic markets (industries) more contestable, and that the higher degree of market contestability improves the overall performance of the economy, measured by the increase in real GDP. This paper finds that the degree of overall contestability is positively and significantly affected by the increase in ICT services in all three groups of countries. This result supports the hypothesis concerning the importance of information in making markets more contestable. Moreover, there is a positive and significant impact of ICT on per capita GDP. As for the impact of increase in the degree of contestability on economic performance, we found that developed countries experienced a positive and significant relation, but such a relation was insignificant in the other groups — developing countries and ERF sample.en-USOctober University for university of Economic GrowthEconomics performanceECONOMICArticle
