OECD: What is Private Investment in Transport Infrastructure and Why is it Difficult?

Investment in infrastructure can be an important contributor to economic growth. Currently, considerable research effort is directed at how to increase the flow of private investment into infrastructure. The concepts related to this effort are clear to researchers and practitioners who deal with them each in their own specialised area. To policy makers, these distinctions are not necessarily clear.
This paper serves as a primer for policy makers interested in the subject of transport infrastructure and private investment. The paper revisits the nature of infrastructure and the basic underlying challenges of private investment in the transport sector. It reviews how these difficulties can be overcome through specific contractual and regulatory solutions.
