Infrastructure is a crucial driver of economic growth. In developing countries, however, there are significant infrastructure deficits. The G20 estimates that $1.5 trillion will be required annually to plug these deficits and that the money will largely need to come from private sources. While private investment in infrastructure in developing countries has grown significantly over the past 10 years, major challenges remain.

These papers explore five challenges that have prevented a greater level of private investment in infrastructure to date, and present five possible solutions to ease constraints and deliver better results for low-income countries.
