在葡萄牙，直到最近，电信公司还通过数字用户线路和电缆调制解调器提供宽带上网服务。我们估计了这两项业务的结构性分离对互联网宽带接入的影响。使用消费者层面的面板数据和随机效应混合logit模型，我们估计了需求的价格弹性和宽带接入互联网的边际成本。基于这些估计，我们模拟了结构性分离对价格和社会福利的影响。我们的估计表明，结构性分离将导致福利大幅增加。这些结果对一些国家允许电话和有线电视网络双重所有权的政策提出了质疑。
In Portugal, until recently, the telecommunications incumbent offered broadband access to the Internet, both through digital subscriber line and cable modem. We estimate the impact on broadband access to the Internet of the structural separation of these two businesses. Using a panel of consumer level data and a random effects mixed logit model, we estimate the price elasticities of demand and the marginal costs of broadband access to the Internet. Based on these estimates, we simulate the effect of structural separation on prices and social welfare. Our estimates indicate that structural separation would cause a substantial welfare increase. These results raise questions about the policy of some countries of allowing the dual ownership of telephone and cable networks.
