概要 |
The process of liberalization and privatization of telecommunications in the 1980s, during which attention was focused on opening up the sector, led to a consensus on entrusting infrastructure financi...ng entirely to the market. Hence, direct public intervention was ruled out and the role of policymakers was limited to regulatory actions. Regulatory interventions are designed by independent regulatory authorities, supervising firms with significant market power. However, when expansion of broadband services was targeted, the high cost of broadband line construction and the low propensity of providers to invest in rural and peripheral areas once again placed the issue of financing telecommunications networks into the hands of policymakers. How the interventions should be implemented became the issue of the debate. Previous studies offer conflicting results regarding the timing and interaction between demand-side and supply-side policies, mainly because the specific conditions and the context in which these tools are applied matter. Thus, by considering the time dimension, this study examines the direct public policies adopted in selected countries and describes how those policies have developed.続きを見る
