本文研究了一国的监管环境和竞争环境对第二代(2G)移动通信性能的影响。我们考虑了部门绩效的三个维度：进入时间、服务价格和扩散。我们讨论了由于新技术商业化时间的跨国差异而产生的非随机选择问题。我们的实证研究表明，这种类型的样本选择可能确实是技术扩散和对感兴趣的政策变量的收益率偏向估计的跨国研究中的一个实质性问题。我们的估计结果表明，标准化加速了2G的进入和扩散，尽管标准内竞争引发的价格竞争不如标准间竞争那么激烈。我们还发现，早期的垄断者会更积极地定价，以建立安装基础。此外，我们发现，现有技术(即固定线路电话)市场的自由化加快了2G的商业化。
This paper studies the effects of a country’s regulatory setting and competitive environment the performance of second-generation (2G) mobile on telecommunication. We consider three dimensions of sector performance: entry time, service prices and diffusion. We address the question of non-random selection arising from cross-country differences in the timing of the commercialization of new technologies. Our empirical exploration shows that this type of sample selection may indeed be a substantial problem in cross-country studies on technology diffusion and yield biased estimates of the policy variables of interest. Our estimation results suggest that standardization accelerates 2G entry and diffusion, although within-standards competition triggers less aggressive price competition than between-standards competition. We also find that an early monopolist will price more aggressively to build up an installed base. Furthermore, we find that liberalizing markets for incumbent technologies (i.e., fixed line telephony) has accelerated the commercialization of 2G.
