Abstract

Abstract The aim of this paper is to study the occurrence of Fixed-Mobile Substitution (FMS) in the Middle East North African (MENA) region. While there have been many studies on developed countries, empirical evidence for developing countries is somehow limited. In the last few years, mobile cellular subscriptions achieved a tremendous growth across the MENA region making it the second fastest growing region in the world in terms of mobile subscriptions in 2012, and the fastest growing region in terms of mobile traffic in 2014. Fixed subscriptions have also grown but at a slower rate than mobile subscriptions. Using unbalanced data on 17 MENA countries over the period 1990–2009, we explore the relationship between fixed and mobile telephone services by using dynamic panel data models. We find empirical evidence for asymmetric one-way substitution between fixed-lines and mobile phones and we estimate own- and cross-price elasticities for fixed and mobile telephone services in MENA region. The results are then used to derive policy implications in terms of market redefinition, taxation policies, extension of universal services and broadband markets.

中东和北非国家的固定移动替代:固定线路市场的未来

摘要本文的目的是研究固定移动替代(FMS)在中东北非(MENA)地区的发生。虽然对发达国家的研究很多，但对发展中国家的经验证据却有限。在过去的几年中，移动蜂窝用户在中东和北非地区实现了巨大的增长，使其成为2012年全球移动用户增长第二快的地区，并在2014年成为移动流量增长最快的地区。固定用户也在增长，但增速低于移动用户。本文利用17个MENA国家1990-2009年的不平衡数据，利用动态面板数据模型探讨了固定电话和移动电话服务之间的关系。我们发现了固定电话和移动电话之间不对称单向替代的实证证据，并估计了中东和北非地区固定电话和移动电话服务的自有和交叉价格弹性。然后利用这些结果推导出市场重新定义、税收政策、普及服务和宽带市场方面的政策含义。

期刊介绍： The Review of Network Economics seeks to help policy makers, academics, and practitioners keep informed of new research and policy debate in network economics and related subjects that are relevant to the study of network industries. By publishing high quality research on topical issues relevant to network industries, it is hoped readers will be able to gain a deeper understanding of the economic issues involved and that this will improve the quality of decision making by private and public organisations, and debate among researchers. The articles can cover specific network industries, or may deal with general issues that have relevance to a number of different network industries, including topics in the economics of networks, regulation, competition law, or industrial organisation. Papers that provide insights into policy debates are especially welcome, as are up-to-date surveys, book reviews, and comments.
