This paper describes a parsimonious approach to the economic analysis of transportation investments. In a gravity model of trade, project benefits may be summarized by a money metric for the change in market access experienced by all cities due to the investment. This metric is equivalent to the...

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 presents a structural general equilibrium model to analyze the effects on trade, welfare, and gross domestic product of common transport infrastructure. Specifically, the model builds on the framework by Caliendo and Parro (2015)-a Ricardian model with sectoral linkages, trade in...
