Road maintenance constitutes a significant component of public transportation spending at all levels of government. Formulation of efficient transportation infrastructure policy requires information about factors affecting road and traffic conditions. We generate the first causal evidence that...

This paper quantifies the value of US highways and their contribution in shaping regional specialization patterns and facilitating internal and external market integration. We develop a multisector general equilibrium model of interregional and international trade with many locations in the...

Penology in the Jim Crow South centered on the chain gang. Gangs ostensibly served three purposes: their severity served as a deterrent; their putting convicts to work on roads and other public improvements reduced the taxpayers' costs of infrastructure; and their discriminatory implementation...

With maintenance costs accounting for a large proportion of road budgets, this report assesses the economic and technical feasibility of innovative wearing courses for long life road pavements. While having higher initial costs, such wearing courses have the potential to dramatically reduce...

Much of the current policy debate has considered infrastructure charges as a form of “fiscal” instrument for managing transport demand. The Round Table analysed the opportunities for setting infrastructure service prices so that they also provide guidance for the supply of services. It...

The importance of increments to an existing highway system depends upon their contributions to the accessibility provided by the existing network. Nearly 40 years ago, Mohring [1965] suggested this logic for planning optimal highway investment programs. He argued it could be implemented by...

A large fraction of Uganda's population continues to earn a living from quasi-subsistence agriculture. This paper uses a static general equilibrium model to explore the relationships between high transportation costs, low productivity, and the size of the quasi-subsistence sector. We...

In public sector procurement, social welfare often depends on the time taken to complete the contract. A leading example is highway construction, where slow completion times inflict a negative externality on commuters. Recently, highway departments have introduced innovative contracting methods...
