Each year in the US, hundreds of billions of dollars are spent on transportation infrastructure
and billions of hours are lost in traffic. We develop a quantitative general equilibrium spatial …

This paper considers the evolution of global transportation usage over the past half century
and its implications for supply chains. Transportation usage has more than doubled as costs …

What do recent advances in economic geography teach us about the spatial distribution of
economic activity? We show that the equilibrium distribution of economic activity can be …

We study the trade effects of the 2021 supply chain disruptions on containerized agricultural
exports from California ports. Our event studies show that port congestion and container …

Container ships travel between a fixed set of origins and destinations in round trips, inducing
a negative correlation in their freight rates. I study the implications of this round trip effect on …

This paper examines the structure of the shipping network and its implications on global
trade and welfare. Using novel data on the movements of container ships, we calculate …

We evaluate high‐frequency bill of lading data for international trade research. These data
offer some advantages over both other publicly accessible trade data and confidential …

Seaports facilitate the fast flow of goods across space, but ports also entail local costs borne
by host cities. We use the introduction of containerized shipping to explore the effects of port …

While international trade can offer gains from specialization and access to a wider range of
products, it is also closely interlinked with global environmental problems, above all …

We examine the economic and environmental impacts of improvements and disruptions in
multimodal transport networks. Our quantitative spatial equilibrium model incorporates …
