It is widely acknowledged that infrastructure plays a fundamental role in stimulating economic growth in developing countries. Conversely, the large infrastructure gap in low and middle income countries (LMICs) is a major impediment to growth. The deficit is particularly acute for Sub-Saharan Africa (SSA) where new infrastructure investment needs are estimated at US $22 billion a year for the next decade. While many SSA countries are unable to finance these investments on their own, the continent has experienced a significant increase in infrastructure investments since the 2000s. A substantial portion of these investments is coming from "non-traditional" sources: The private sector and emerging countries, especially China. However, the determinants of these investments, the terms of engagement underlying the new flows, and the associated tradeoffs are not well-understood. From the policy perspective, while the rise of funding for infrastructure is welcome, if the resources are not channeled adequately, the risk is that the funds will not be invested in a way that would contribute to economic growth and development, and will therefore be wasted. Thus, the overall goal of this dissertation is to better understand the new flows and their policy implications.

Given that the issues associated with Chinese and private sector financing are very different in nature, the dissertation takes a mixed-method approach and is broadly divided into two parts. In a first part, a systematic qualitative comparison between the Chinese approach to infrastructure financing in SSA and that of other large multi- and bilateral financiers is undertaken. Unlike previous research, this dissertation takes a holistic approach and compares the different financing models using a framework that assesses infrastructure financing along the "lifecycle" of an infrastructure investment — from the planning stage to the monitoring and upkeep of the facility once it has been built. In a second part, the determinants and the extent of private participation in infrastructure (PPI) in SSA are compared to that in other LMICs using a cross-country panel regression framework. Additionally, using theoretical findings from the literature on the broader topic of private delivery of public services, the contracting mechanisms used for PPI are further explored.
