We estimate an equilibrium model of residential sorting with endogenous traffic congestion to evaluate the efficiency and equity impacts of urban transportation policies. Leveraging fine-scale data on household travel diaries and housing transactions with home and work locations in Beijing, we...

In cities worldwide, the widespread use of single occupancy cars often leads to traffic congestion and its associated ill effects. Using high frequency data from Google Maps, we test whether high-occupancy vehicle (HOV) policies can be an effective tool to combat congestion. Using the unexpected...

This paper analyses the degree to which infrastructure reliability and urban economic activity in several African cities is impacted by flooding. It combines firm-level micro data, flood maps, and several spatial data layers across cities through a harmonized geospatial network analysis. The...

Designing public transport networks involves tradeoffs between extensive geographic coverage, frequent service on each route, and relying on interconnections as opposed to direct service. These choices, in turn, depend on individual preferences for waiting times, travel times, and transfers. We...

Developed at the request of the Mexican G20 Presidency for consideration by the Finance Ministers and Central Bank Governors at the G20 Leaders' Summit in Mexico, and jointly prepared with the Asian Development Bank, this policy paper positioned green transport in the context of cities...

Transport infrastructure is deemed to be central to development and consumes a large fraction of the development assistance envelope. Yet there is debate about the economic impact of road projects. This paper proposes an approach to assess the differential development impacts of alternative road...

Will politics lead to over-building or under-building of transportation projects? In this paper, we develop a model of infrastructure policy in which politicians overdo things that have hidden costs and underperform tasks whose costs voters readily perceive. Consequently, national funding of...

This paper takes a first look at the trade effects of China's Belt and Road Initiative, also referred to as the New Silk Road, on the 71 countries potentially involved. The initiative consists of several infrastructure investment projects to improve the land and maritime transportation in the...

The Belt and Road Initiative, due to its diverse and extensive infrastructure investments, poses a wide range of environmental risks. Some projects have easily identifiable and measurable impacts, such as energy projects' greenhouse gas emissions. Others, such as transportation infrastructure,...

This paper develops a computable spatial equilibrium model of Central Asia and uses it to analyze the possible effects of the Belt Road Initiative on the economy of the region. The model captures international and subnational economic units and their connectivity to each other and the rest of...
