The recent development of quantitative urban models provides a new set of tools for evaluating transport improvements. Conventional cost-benefit analyses are typically undertaken in partial equilibrium. In contrast, quantitative urban models characterize the spatial distribution of economic...

In this article, we show that working from home is much more prevalent in the Nordic countries than in the rest of Europe and we discuss potential causes and labor market consequences of this stylized fact. Likely contributing causes include a good technological infrastructure and comparatively...

We study the relationship between firm centralization and organizational reproduction in satellite locations. For decentralized firms, the ethnic compositions of inventors in satellite locations mostly resemble their host cities, with little link to the inventor composition of their parent...

Charging infrastructure is critical to electric vehicle (EV) adoption, but for chargers to be most useful, EV drivers need to know in real time where they are and whether they are working and available. We investigate the availability of real-time data from DC fast chargers on six major US...

The Trump Administration's tariffs created a wedge between mutually beneficial trades between China's producers and U.S. consumers. Moving production to nearby Vietnam allows firms to jump the tariff wall. Within Vietnam, cities closer to China with respect to distance and industrial mix grow...

We examine the rise of dark shipping - oil tankers disabling AIS transceivers to evade detection - amid Western sanctions on Iran, Syria, North Korea, Venezuela, and Russia. Using a machine learning-based ship clustering model, we track dark-shipped crude oil trade flows worldwide and detect...

We build a granular Geographic Information System (GIS) database that covers China's national highways, modern motorways, traditional railways, high-speed railways, and waterways at an annual frequency from 1993 to 2020. After describing the database and its construction, we characterize the...

This paper documents three new stylized facts showing that truckers in Colombia frequently choose to make complex chains of shipments in a single trip before returning home. It then provides a newmodel of optimal trucker trip-chaining with a general geography that is consistent with these facts

Replacing fossil fuels in the name of decarbonization is necessary but will be particularly difficult due to their as-yet unrivaled bundle of attributes: abundance, ubiquity, energy density, transportability and cost. There is a growing commitment to electrification as the dominant...

This paper investigates the reversibility of the effects of transport infrastructure investments, based on a programme that removed much of the rail network in Britain during the mid-20th Century. We find that a 10% loss in rail access between 1950 and 1980 caused a persistent 3% decline in...
