Geography shapes economic outcomes in a major way. This paper uses spatial empirical methods to detect and analyze trade patterns in a historical data set on Chinese rice prices. Our results suggest that spatial features were important for the expansion of interregional trade. Geography...

Recent studies suggest that intranational trade is "excessive' compared to international trade. An intuitive explanation for this home bias is provided by national trade barriers. A dataset of trade between US states, however, reveals that home bias extends to subnational units. The data suggest...

Extending McCallum's (1995) result, based on a gravity model of 1988 trade flows, that a typical Canadian province trades 22 times more with other provinces than with U.S. states of similar size and distance, this paper asks how Quebec trade patterns compare with those of other provinces. The...

A structural gravity model is used to estimate barriers to services trade across many sectors, countries and time. Since the disaggregated output data needed to flexibly infer border barriers are often missing for services, we derive a novel methodology for projecting output data. The empirical...

The Covid-19 pandemic has introduced huge numbers of employers and employees to remote work. How many of these newly remote jobs will go overseas? We offer a rough quantification based on two observations: 1) offshore work is trade in services, and 2) the number of telemigrants is the volume of...

Preferential liberalization of trade in services is a central feature of the new regionalism. "GATS-Plus" and "GATS-Minus" have become the distinctive characteristics of the service RTAs and this paper aims to investigate and distinguish the different effect of the "GATS-Plus" and "GATS-Minus"...

We investigate the role of national institutions on subnational African development in a novel framework that accounts both for local geography and cultural-genetic traits. We exploit the fact that the political boundaries in the eve of African independence partitioned more than two hundred...

We study the uneven effects of a commodity boom, documenting its impact across workers based on their skill and on the region where they live. To this end, we develop a dynamic quantitative model of an economy with many regions connected through interregional trade and migration. Empirically, we...

A large literature has shown that geographic frictions reduce trade, but has not clarified precisely why. We provide insights into why such frictions matter by examining which parts of trade these frictions reduce most. Using data that tracks manufacturers' shipments within the United States on...

Regional trade in South America since independence has long been much smaller than would be expected if geography were the only constraint on trade. Several potential explanations exist: low technological and demand complementarities; low productivity; high natural and policy barriers to trade....
