Chapter 2 Infrastructure Development through Public–Private Partnerships in Africa

This chapter uses data from the World Bank’s Private Participation in Infrastructure project database, and hand-collected evidence on project performance, to examine how PPPs are applied to infrastructure development in Africa, and how well they have delivered expected benefits. It has two analytical parts: an investment trend analysis and a meta-analysis of project performance and explanatory factors. The analysis shows growth both in number and volume of PPP investments that is weaker than that observed in other developing regions, and more volatile. The performance of PPP contracts appears to be improving over time with an overall cancelation rate of 7% over the assessment period. Although PPPs have contributed to increasing infrastructure stock, they have not completely met their potential, especially with respect to increasing infrastructure access rates. The main determinants of performance include accuracy of costing and allocation of risks, consistency of macro policies with the objectives and functioning of PPPs, coherence of sector policies and plans and local capacity. Contract cancellations are mainly explained by the misalignment of outcomes with government objectives, in particular, access and investment objectives. These findings suggest that PPP application should be well planned to ensure coherence of a wide range of policies, readiness of institutions and capacity of public sector actors. This chapter contributes to closing information gaps on a relatively novel policy instrument, and provides useful evidence to support prudent policy making at the time of considerable growth in PPP application.
