Recent academic research on maritime shipping has been affected by two factors: (i) changes in shipping technology and market structure and (ii) the explosion of new micro data sets in shipping and international trade. This paper describes this research, focusing on containerized and dry-bulk...

We evaluate the expected impact of the International Maritime Organization’s 2023 regulatory regime (IMO2023) that caps CO2 emissions from global maritime shipping. Focusing on U.S. imports—for which we compile granular vessel, route, emission, and trade data— we structurally estimate a...

We evaluate the expected impact of the anticipated International Maritime Organization’s regulatory regime that will cap CO2 emissions from global maritime shipping. Focusing on U.S. imports---for which we compile granular vessel, route, emission, and trade data---we structurally estimate a...

This paper documents that, even within a narrowly defined product and port-to-port route, the maritime international freight rates are lower for larger importing firms. Even after controlling for shipment sizes, the 90th-percentile importing firm faces a 20% lower freight rate and, as a...

We investigate the factors that, in addition to preferences, affect the extent to which richer households pay more for a given durable good with respect to their expenditures on nondurables, defined as the quality slope. We show theoretically and confirm empirically that the quality slope...

We explore theoretically and empirically the within-route price discrimination in liner shipping and condition it on the market density. Using transaction-level data from over 200 Chilean import port-to-port routes, we confirm our theoretical predictions and demonstrate their robustness and...
