Abstract

In this paper we study how the coexistence of access regulations for legacy (copper) and fiber networks shapes the incentives to invest in network infrastructure. To this end, we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous entrants and test its main predictions using panel data from 27 EU member states over the last decade. Our theoretical model extends the existing literature by, among other things, allowing for heterogeneous entrants in internet access markets, as we consider both other telecom and cable TV operators as entrants. In the empirical part, we use a novel data set including information on physical fiber network investments, legacy network access regulation and recently imposed fiber access regulations. Our main finding is that more stringent access regulations for both the legacy and the fiber networks harm investments by incumbent telecom operators, but, in line with our theoretical model, do not affect cable TV operators.
加速互联网:欧洲光纤基础设施的监管和投资
在本文中,我们研究了传统(铜)和光纤网络的接入法规的共存如何影响对网络基础设施投资的激励。为此,我们开发了一个理论模型来解释现有电信运营商和异质进入者的投资激励,并使用过去十年来自27个欧盟成员国的面板数据来测试其主要预测。我们的理论模型扩展了现有文献,除其他外,允许互联网接入市场的异质进入者,因为我们将其他电信和有线电视运营商视为进入者。在实证部分,我们使用了一个新的数据集,包括物理光纤网络投资、传统网络接入法规和最近实施的光纤接入法规的信息。我们的主要发现是,对传统网络和光纤网络更严格的接入规定损害了现有电信运营商的投资,但与我们的理论模型一致,对有线电视运营商没有影响。
