This study presents an ex post comparative assessment of the relative performance of three Latin American broadband network emblematic projects implemented through public-private projects (PPP). Results show that the relative performance of these projects is extremely sensitive to differences in contractual design and regulatory approaches applied in each case. The detailed examination and comparative analysis of these experiences allowed us to extract important lessons in terms of design and implementation of PPP in telecommunications sector. In particular, our analysis finds that imperfect financing and demand risk allocations in projects can jeopardize their operational and financial sustainability. As well, the examination of these experiences allows us to conclude that in markets characterized by continuous economic and technological transformations, vertical separation restrictions imposed for reducing the risk of increasing market power and concentration may not be justified. As well, analysis shows that in such evolving contexts, a more flexible and adaptable regulatory approach is recommendable. Finally, our analysis reveals the role of complementary policies in the context of the implementation of countries’ digital strategies, as a means that contribute to ensure the accomplishment of broadband accessibility national targets.

本研究对通过公私项目 (PPP) 实施的三个拉丁美洲宽带网络标志性项目的相对绩效进行了事后比较评估。结果表明，这些项目的相对绩效对合同设计和在每种情况下应用的监管方法的差异极为敏感。对这些经验的详细考察和比较分析使我们能够在电信行业PPP的设计和实施方面汲取重要的经验教训。特别是，我们的分析发现，项目中不完善的融资和需求风险分配可能会危及项目的运营和财务可持续性。同样，对这些经验的审查使我们得出结论，在以持续经济和技术变革为特征的市场中，为降低市场权力和集中度增加的风险而施加的纵向分离限制可能是不合理的。同样，分析表明，在这种不断变化的背景下，更灵活和适应性更强的监管方法是值得推荐的。最后，我们的分析揭示了补充政策在实施国家数字战略的背景下的作用，作为有助于确保实现宽带接入国家目标的一种手段。建议采用更灵活和适应性更强的监管方法。最后，我们的分析揭示了补充政策在实施国家数字战略的背景下的作用，作为有助于确保实现宽带接入国家目标的一种手段。建议采用更灵活和适应性更强的监管方法。最后，我们的分析揭示了补充政策在实施国家数字战略的背景下的作用，作为有助于确保实现宽带接入国家目标的一种手段。
