For example, a large number of theoretical and empirical studies have pointed to the substantial positive impacts of infrastructure development on economic growth (United Nations, 2016). Studies have found a unidirectional causality from infrastructure to output growth from 1975 to 2007 (Sahoo, Dash and Nataraj, 2010). Additionally, a long-term positive impact on economic growth may be obtained by investments in power and telecommunications (Egert, Kozluk and Sutherland, 2009). Investing in infrastructure also has a multiplier effect as it stimulates other capital investment, including in the private sector, resulting in further economy-wide productivity growth and a subsequent improvement of social development In particular, by increasing investment, infrastructure development contributes to improved mechanisms for reducing rural-urban development gaps. It also boosts jobs and raises real wages. Furthermore, a greater focus on social infrastructure investment can enhance access to basic social services, especially for the most marginalized and vulnerable groups of communities.
