This paper studies the impacts of the large-scale Road Sector Development Program in Ethiopia between 1997 and 2016 on local economic activity and land cover (urbanization and cropland). It exploits spatial and temporal variation in road upgrades across Ethiopia, together with high-resolution...

Engineering procurement and construction (EPC) is a normative practice globally approved since China has been engaging in international cooperation under the Belt and Road Initiative (BRI) infrastructure development. EPC has been adopted in the delivery of BRI infrastructure projects in other...

This report presents the results of an impact evaluation of the Pradhan Mantri Gram Sadak Yojana (PMGSY) rural roads program in India. The program targeted the provision of all-weather roads to about 178,000 habitations across India. The impact evaluation uses a difference-in-difference approach...

At present, labour unions of waste disposal agencies and company management are at loggerheads, frequently turning out contradictory sanitation assessments. This reveals a shifting outlook of sanitation accomplishment that should be resolved. Unfortunately, there is scanty research on road...

This paper discusses Norway’s zero-growth objective for passenger car traffic. It focuses on Oslo’s experience with removing parking space, improving walking and cycling conditions and reducing road capacity on main motorways. The paper highlights the effectiveness of reallocating road and...

This study analyzes the impacts of the recent rural road development in Ethiopia on welfare and economic outcomes. The identification of the impacts relies on a difference-in-differences matching approach, taking advantage of the nationally representative household survey and the original road...

Rural accessibility is the only metric used in the Sustainable Development Goals to track progress toward better transport services in low- and middle-income countries. This paper estimates the rural accessibility index, defined as the proportion of the rural population who live within 2...

The People's Republic of China (PRC) has made massive investments since the late 1990s in highway infrastructure, connecting its rural and urban regions. In this paper, we study the impact of highway investments on the educational choices in rural PRC. Because enhanced connectivity facilitates...

Africa's interior-to-coast roads are well suited to export natural resources, but not to support regional trade. Are they the optimal response to geography and comparative advantage, or the result of suboptimal political distortions? We investigate the political determinants of road paving in...

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...

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...

We investigate the effects of the recently constructed Chinese national highway system on local economic outcomes. On average, roads that improve access to local markets have small or negative effects on prefecture economic activity and population. However, these averages mask a distinct pattern...

India has accorded a high priority to road infrastructure development through Public-Private Partnership (PPP) and it has set a high target for investment inflows. Yet, it is widely held that road/highway infrastructure has not been developing at required pace and that the road infrastructure...

A significant amount of resources is spent every year on the improvement of transportation infrastructure in developing countries. In this paper, we investigate the effects of one such large project, the Golden Quadrilateral in India. We do so using a model of internal trade with variable...

Nearly one billion people worldwide live in rural areas without access to the paved road network. This paper measures the impacts of India's $40 billion national rural road construction program using regression discontinuity and data covering every individual and firm in rural India. The main...
