I conduct a comprehensive analysis of China's international and domestic border effects. My results confirm the negative impact of administrative borders on exports. In my analysis, I account for multilateral resistance terms, which were omitted in previous relevant studies. My findings show...

This study investigates the dynamics of human capital in borderlands, focusing on the case of the Minho River border between Spain and Portugal. We examine how this capital influences company sales in these culturally and economically intertwined regions. The problem is critical due to the...

The use of location quotients for the estimation of regional input-output tables has been found to be a useful and efficient tool to estimate intraregional production coefficients and multipliers. This paper considers some regionalisation methodologies based on location quotients for the...

We quantify the economic impact of a potential secession of Catalonia from Spain. Using a novel dataset of trade flows between 17 Spanish sub-national regions and 142 countries, we estimate effects of different levels of borders on trade flows and uncover heterogeneity in country-to-country,...

This study estimates international and interprovincial migrants' impact on interprovincial trade using panel data from 1981- 2016 for Canadian provinces. Estimated results show that migration plays a significant role in determining Canadian interprovincial trade. Although the stock of...

Domestic trade costs are anecdotally high in the Philippines, and yet a systematic and spatially comparable metric of trade costs is unavailable. This paper fills this gap by estimating province border effects, or a province’s tendency to trade with itself rather than with other provinces....

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...

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...

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...

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...

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...

Wolf (2000) demonstrates that trade within the U.S. appears substantially impeded by state borders. We revisit this finding with improved data. We show that much intra-national home bias can be explained by wholesaling activity. Shipments by wholesalers are much more localized within states than...

We show that 'home bias' in trade patterns will arise endogenously due to the co-location decisions of intermediate and final goods producers. Our model identifies four implications of home bias arising out of specialized industrial demands. Regions absorb different bundles of goods. Buyers and...

This paper examines the home country bias in the goods market among OECD countries. An average country imports about two and a half times as much from itself as from an otherwise identical foreign country, after controlling for sizes of exporter and importer, their direct distance, geographic...

We consider a model with several regions whose technological ability and factor endowments are identical and in which transport costs between regions are non-negligible. Nonetheless, certain goods are sometimes produced by multiple firms all of which are located in the same region. These goods...

This article exploits the creation of a paradigmatic multi-ethnic state, Yugoslavia, to examine if, to what extent, and why the effect of ethnic ties on trade costs changes over time. We compile and examine a panel of over 550,000 inter-urban price gaps spanning the area of Yugoslavia in the...

This paper analyses the effect of international borders and of trade agreements at international borders on subnational (i.e. regional) growth. We construct an extensive panel dataset covering 1,350 regions in 86 countries worldwide between 1950 and 2017. Our results show that international...

We investigate whether time-persistent cultural borders impede economic exchange across regions of the same country. To measure cultural differences we evaluate, for the first time in economics, linguistic micro-data about phonological and grammatical features of German dialects. These data are...

The paper proposes a modelling approach for euro area goods and services trade volumes and prices on the basis of a break-down of trade data into their intra- and extra-area components. Using the evidence from the newly estimated trade equations, the paper gives new insights into two important...

We use the new dataset of trade flows across 269 European regions in 24 countries constructed in Santamaría et al. (2020) to systematically explore for the first time trade patterns within and across country borders. We focus on the differences between home trade, country trade and foreign...

We examine impacts of market integration on the development of American manufacturing, as railroads expanded through the latter half of the 19th century. Using new county-by-industry data from the Census of Manufactures, we estimate substantial impacts on manufacturing productivity from relative...

International trade in manufacturing goods has risen strongly over the past decades, contributing to the expansion of global value chains (GVCs). This paper studies how two factors contributed to this rise since 1970: (i) declining "border effects" that are arguably related to the ICT revolution...

This paper undertakes the simultaneous estimation of import elasticities of substitution (trade elasticities) within European Union (EU) regions, differentiating between imports from regions belonging to the same country (national or interregional trade) and regions belonging to other EU...

We create two novel datasets - the starting dates of Roll-On Roll-Off Terminal System (RRTS) service by route, and interprovincial land trade - to evaluate the effects of the RRTS on agricultural trade costs within the Philippines as measured by border effects. We find province border effects to...
