In countries, such as Singapore, that have implemented vehicle congestion policies, recent years have seen a shift towards motor vehicle taxes based on car use. Ownership taxes reduce the number of cars on the road, leaving the price per trip largely unaffected. Use taxes such as fuel taxes and...

Congestion plays a central role in urban and transportation economics. Existing estimates of congestion costs rely on stated or revealed preferences studies. We explore a complementary measure of congestion costs based on self-reported happiness. Exploiting quasi-random variation in daily...

Using three years of data from the 47 prefectures of Japan, we estimate behavior of households who simultaneously make discrete decisions about vehicle ownership and continuous decisions about driving distance. We use the estimated parameters to calculate elasticities and to simulate the effects...

We propose a theory-inspired measure of the accessibility of a city's center: the size of the surrounding area from which it can be reached within a specific time. Using publicly available optimal-routing software, we compute these "accessibility zones" for the 109 largest US and European...

What is the impact on intra-national trade and regional economic outcomes when the quality and lane-capacity of an existing paved road network is expanded significantly? We investigate this question for the case of Turkey, which undertook a large-scale public investment in roads during the...

The Inca Empire was the last of a long series of highly developed cultures in pre-colonial South America. It stretched across parts of the current territories of Argentina, Bolivia, Chile, Colombia, Ecuador and the whole of Peru. The Inca Road was its 30,000-kilometer-long transportation system....

"China proposed the Belt and Road Initiative in 2013 to improve connectivity and cooperation on a transcontinental scale. This study, by a team of World Bank Group economists led by Michele Ruta, analyzes the economics of the initiative. It assesses the connectivity gaps between economies along...

The six land corridors that are the 'Belt' part of the Belt and Road Initiative (BRI) connect more than sixty countries. As the initiative progresses, policy makers, analysts and researchers are trying to answer a few open questions of which the most common are: How can a country best benefit...

China's "Belt and Road Initiative" (BRI) includes major infrastructure investment projects - roads, ports, railways - that aim to improve connectivity along a number of transport corridors spanning 71 countries. In this paper we find that notwithstanding the large scale of the initiative,...

This paper examines the level of investment protection for selected countries along the Belt andRoad Initiative (BRI), based on coding the textual content of 17 investment laws and 648international investment agreements (IIAs). We find substantial heterogeneity in the levels ofprotection...
