Welfare effects of the Telecommunication Reform in Mexico

The telecommunication sector in Mexico was highly concentrated until 2013. The sector was mostly composed by a dominant player, a rationed market (low density of services), a poor institutional design, high tariffs, and weak regulation agents. The Herfindahl-Hirschman (HHI) index was 5333 for mobile telephone and 7,029 for fixed telephone services—among the highest scores in the world. In order to promote competition in the sector, Congress approved a reform in 2013 to establish a new regulator empowered to impose asymmetrical rules in the case of the predominance of a single firm. A declaration of preponderance of the dominant player was issued, promoting free interconnection rates and the mandatory sharing of its passive and active infrastructure with the rest of the firms in the industry. The new institutional design led to increased competition in the sector, decreasing the mobile and fixed telephone prices while increasing the coverage and penetration of these services. In this article, an applied general equilibrium model for the Mexican economy is employed to assess the impact of the Telecommunication Reform in Mexico in the telephone sector, consumer welfare, and income distribution. The model is static, encompassing 10 types of consumers (rural and urban and the five income quintiles) and 40 sectors (of which four are disaggregate telecommunications industries). It assumes fixed wages and capital rental prices as well as idle resources. The main results indicate that the effects of the reform are not minor; the drop in telephone prices would reduce the general consumer price index by almost 2%, and the value added would increase by more than 3%, benefiting mainly households in the highest income quantiles.

Forecasting VoWLAN technology for the Taiwan mobile telecommunication industry

Disruptive innovation is always a great challenge to the management of incumbent firms, especially in fast-changing industries. In this study, scenarios were developed to facilitate strategic decision-making by incumbent mobile telecommunications firms that confront the threats of disruptive technology of voice over wireless local area network (VoWLAN). Combining various possible outcomes of uncertain conditions and strategic alternatives available to the incumbent firms, six scenarios were developed: incremental evolution, disruptive evolution, cost deterrence, fierce competition, market pre-emption and market convergence. The results show that a passive ‘do-nothing’ strategy by incumbent firms leads to failure if the disruptive technology is inevitable. However, firms can slow the pace of disruptive technology by applying a price-cut strategy and enjoy several years of profits in the process. Industrial insights and strategic implications obtained from all the scenarios are discussed.     

3G背景下电信竞争模型与接入规制政策研究

3G正在重组我国的电信产业组织,同时对电信运营商商业竞争模式的变革提出要求。本文构建3G背景下电信竞争模型,分析垄断运营商的网络规模决策及网络竞争的福利效应,并对电信接入定价决策及接入规制政策进行分析。本文的主要结论是:垄断运营商缺乏提供普遍服务的激励;在网络规模非对等下,引入电信竞争通常是社会低效率的;在位者提供瓶颈资源的接入定价是社会低效率的,可以采用基于机会成本的有效元素定价对接入服务予以规制。
