Most recently, the Financing for Development Conference in Addis Ababa, Ethiopia sparked even more discussion about the role of public-private partnerships. The official line, spoken in a multitude of tongues, is that PPPs have an important role to play, and results are dependent on projects being procured, managed and regulated well. But one thing is clear in every language: “results” are based mainly on anecdotal evidence and case studies where attribution remains dubious, and findings cannot be generalized as they depend on the particular characteristics of the specific projects.
We can do better. As economists, development professionals, finance experts, and explorers of new and creative solutions to solve the problem of poverty, we must do better. And we will – with better data.
Lack of data has constrained the empirical literature on PPPs, in turn constraining our ability to tap the territory of PPPs and its potential to transform markets. After all, what do we really know about the economic impact of PPPs? Our first-ever literature review, underway now (the first draft is available at https://www.pppknowledgelab.org/ppp_document/2384), has laid an initial foundation for knowledge, and we have made the first draft available so that colleagues and interested individuals and organizations can contribute their data.
