Accordingly, infrastructure is typically defined in terms of the respective industrial sectors involved in the provision of these key essential services for the community. Specifically, infrastructure can be divided into economic and social. Whereas economic infrastructure includes the transportation, utilities and telecommunications sectors, social infrastructure typically comprises the health and educational sectors (Weber and Alfen, 2010). Due to factors such as climate change, growth, technological process and urbanization, the worldwide demand for new infrastructure is expected to expand significantly over the next few decades. Additionally, the existing infrastructure in countries of the Organization for Economic Co-operation and Development (OECD) is aging rapidly and therefore needs to be renewed, upgraded or maintained. Numerous studies attempt to quantify these future investment needs on a global basis. For instance, the OECD estimates approximately $71.1 trillion infrastructure investment demands by 2030 (OECD, 2006; OECD, 2007). More recently, the OECD even raised the number to $82.2 trillion (OECD, 2012), which corresponds to annual investment needs of nearly $3 trillion. The mismatch between investment needs and financial resources is widely known as the “infrastructure gap” (Inderst, 2013).
