Highway construction occurs nowadays mainly through widening of existing roads rather than building new roads. This paper documents that highway widenings considerably reduce congestion in the short run, defined here as 6 years. Using longitudinal microdata from highway detector loops in the...

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...

Evidence for road expansion and electrification as drivers of job creation is limited and mixed, with most studies having considered either one or the other, and only in isolation. This paper estimates the average and heterogeneous impacts of road and electricity investments and the interaction...

The purpose of this study is to evaluate non-traditional means to raise additional private financing for the upgrade and maintenance of developing countries' road networks. To achieve this goal, it combines an in-depth review of Sub-Saharan Africa (SSA) countries' road funds' (RF) performance...

The United States witnessed an unprecedented crime wave in the second half of the twentieth century, with the total index crime rate more than tripling between 1960-1980. Little is known about the causes of this surge in criminal activity across the country. This paper investigates the role...

This paper investigates whether better access to markets through an improved road network plays a role in improving the profitability of firms in India. We construct a district-level market access index using Indian road network shapefiles, district boundaries, and nightlight raster images and...

This paper examines bidding in auctions for state highway construction contracts on Long Island in the early 1980s, in order to determine whether bid rigging occurred. Detection of collusion is possible because of limited participation in the collusive scheme. The paper looks at differences in...

Developing countries, such as SSA, often face a trade-off in investing in highways that interconnect cities vs. rural roads that connect rural villages to markets. Prioritization of either roads requires estimation of the welfare gains from each. This paper estimates the welfare gains from rural...

We examine how highway accessibility influences local employment outcomes. We exploit the stagewise expansion of the "Baltic Sea highway", the largest contiguous highway construction project in Germany since 1945. Results from difference-indifferences estimations and an event study approach show...

This paper quantifies the value of US highways. We develop a multisector general equilibrium model with many locations in the United States (i.e., counties) and many countries. In the model, producers choose shipping routes subject to domestic and international trade costs, endogenous...

Highway construction occurs nowadays mainly through widening of ex- isting roads rather than building new roads. This paper documents that highway widenings considerably reduce congestion in the short run, defined here as 6 years. Using longitudinal microdata from highway detector loops in the...

Since recent years, majority of the construction projects under taken in Addis Ababa City experience a varying magnitude of time overrun in which the projects become late in their completion. Due to different problems encountered during inception, design and implementation phases, the projects...

Infrastructure development programs, and specifically road building aid programs, have long been implemented alongside military interventions in conflict-affected countries. A common aim of these programs has been to reduce violence through increased economic development. This paper examines the...

There are two kinds of traffic congestion at a toll plaza on a highway: congestion in the approach zone and congestion in the departure zone, which has received less attention. The performance improvement in the departure zone can directly reduce congestion in that area and indirectly increase...

Road quality plays an important role, especially in rural areas where most poor households are situated. This study aims to calculate the Rural Access Index (RAI), an indicator of rural road quality (SDG indicator 9.1.1), at the district level, to evaluate the implementation of the Nawacita...

This paper analyses the impact that Spanish road construction had on local population growth between 1787 and 1857. We find that the increase in market access associated to road accessibility had a substantial effect on local population growth. The impact was substantially higher on the...

To date, traffic remains a major source of societal costs in terms of safety and environment. In Flanders, as in other regions and Member States in the European Union, the government counts on current developments in cooperative, connected and autonomous mobility (CCAM) to achieve European...

Reducing drink drive limits is generally regarded an effective strategy to save lives on the road. Using several new administrative data sources, we evaluate the effect of a stricter limit introduced in Scotland in 2014. This reduction had no effect on drink driving and road collisions....

Roads and water are generally seen as enemies, with water responsible for most of the damage to roads, and roads being a major cause of problems such as erosion, waterlogging, flooding, and dust storms. This tension, however, can be reversed. The concept of Green Roads for Water (also known as...

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...

In recent years several countries have started massive highway franchising programs auctioned to private firms. In these auctions, the regulator typically sets the franchise term and firms bid on tolls, or, alternatively, the regulator sets tolls and the winner is the firm that asks for the...

In 2010, Korea’s authorities announced foreign exchange-related macroprudential measures (MPMs) aimed at building resilience against external financial shocks. These measures have greatly contributed to limit systemic risk by curbing excessive capital inflows. Twelve years have passed since...

The simple and relatively mundane act of driving a car, which many of us take for granted, can have a profound impact on many aspects of adulthood. The ability to drive a car can provide a means to pursue education and employment, to earn income, and to ultimately obtain independence. As a young...

While a vast literature examines the prevalence of ethnic voting and clientelism in low-income contexts, empirical tests of whether elections are being used to hold politicians accountable for public goods provision are few. Leveraging a rare exogenous variation in the World's largest rural...

The Brazilian Federal Highway Concession Program use concessionaries to manage roads. They are bound by contract to improve the quality of road corridors and, in return, they are allowed to charge tolls. This article aims to analyze the effects of this Program on the economic performance of...

In procurement auctions, there are situations where a bidder's cost is uncertain at the time of bidding, leading to a "winner's curse." We use bridgework data from the State of Oklahoma and an empirical auction model to explore whether the winner's curse also affects entry, which can have...

Having earned the dubious distinction of being ranked No.1 amongst 199 countries for having the highest number of road accidents annually since the year 2016, India stares at a problem of gargantuan proportions. In the year 2019 alone, there were as many as 449,002 occurrences, resulting in...
