Provision of infrastructure services is one of the development bottlenecks for Latin American and Caribbean countries. As the Infrastructure Services Unit team has found in its analysis and has warned for many years, policies in the region have been characterized by underinvestment, fragmentation, and a lack of resilience-related sustainability, to name but a few qualities. This issue of the bulletin addresses potential problems with long-term infrastructure concession agreements, drawing on theoretical developments regarding incomplete contracts.
