This paper proposes a methodology to prioritize interventions in Peru's road network. A network model is built, linking the country's economic and population centers through indicative corridors, which are defined as the least-cost routes to connect origins to destinations. The network's...

This study explores the role of governance in improving infrastructure reliability. It estimates that increasing infrastructure spending and improving governance in parallel is six times more effective at enhancing transport system performance than increasing spending alone. It also estimates...

This study constructs a microdata set of about 143,000 firms to estimate the monetary costs of infrastructure disruptions in 137 low- and middle-income countries, representing 78 percent of the world population and 80 percent of the GDP of low- and -middle-income countries. Specifically, this...

This paper analyses the degree to which infrastructure reliability and urban economic activity in several African cities is impacted by flooding. It combines firm-level micro data, flood maps, and several spatial data layers across cities through a harmonized geospatial network analysis. The...

This paper combines local election results and geo-referenced road construction data over 1993-2012 to investigate political bias in road infrastructure investment in a democratic setting, focusing on the case of Mexico. Using a regression discontinuity design, the paper finds strong evidence of...

Disruption of infrastructure services can cause significant social and economic losses, particularly in the event of a natural disaster. The World Bank Group and the Government of Japan established the Quality Infrastructure Investment Partnership to focus attention on the quality dimensions of...

The potentially-adverse impact of salinity on paved roads is well-established in the engineering literature. The problem seems destined to grow, as climate-related changes in sea level and riverine flows drive future increases in groundwater sal

South Africa has a comprehensive climate change response strategy to support the transition to a low carbon economy and a climate-resilient society. Improving the national Greenhouse Gas (GHG) inventory and implementing a carbon tax are but two elements that form part of this transition....

This paper uses the construction of India's Golden Quadrangle central highway network, together with comprehensive loan data from the Reserve Bank of India, to investigate the interaction between infrastructure development and financial sector depth. The paper identifies a disproportionate...

This paper provides a framework to assess the impact of infrastructure investment expected under the Belt and Road Initiative (BRI) on the debt vulnerabilities of countries that are located on BRI transport and connectivity corridors in the absence of comprehensive and consistent information on...
