We measure the importance of increasing returns to scale and trade in medical services. Using Medicare claims data, we document that “imported” medical care—services produced by a medical provider in a different region—constitute about one-fifth of US healthcare consumption. Larger...

"An eye-opening rethinking of nineteenth-century American history that reveals the interdependence of the Northern industrial economy and Southern slave labor. The industrializing North and the agricultural South-that's how we have been taught to think about the United States in the early...

A key input to quantitative evaluations of transport infrastructure projects is their impact on transport costs. We propose a new method of estimating this impact relying on widely accessible customs data: by using the route choice of exporters. We combine our method with a spatial equilibrium...

We use new theory and data to study how firms endogenously form production networks across regions and countries. Supplier and buyer relationships form depending on firms' productivity and geographic location. We characterize the normative and positive properties of the spatial distribution of...

Using Medicare claims data, we document that "imported" medical care -- services produced by a medical provider in a different region -- constitute about one-fifth of US healthcare consumption. Larger regions...

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...

I propose a theoretical framework for studying the effects of geographical factors on the distribution of industries across many regions. The geographical feature of each region is summarized by a proximity matrix, whose elements measure the closeness between every pair of regions and depend on...

We examine the within- and across-firm shipment decisions of tens of thousands of goods-producing and goods-distributing establishments. This allows us to quantify the normally unobservable forces that determine firm boundaries; that is, which transactions are mediated by ownership control, as...

A significant amount of resources is spent every year on the improvement of transportation infrastructure in developing countries. In this paper, we investigate the effects of one such large project, the Golden Quadrilateral in India. We do so using a model of internal trade with variable...

"This book examines the relationship between imperial governance and political economy in eighteenth-century Britain, particularly in Canada and Ireland. It is concerned with the way economic ideology and party politics were mutually constitutive; and with the way extra-parliamentary interests...

This paper proposes methods to incorporate firm heterogeneity in the standard input-output table-based approach to portray the domestic segment of global value chains in a country. The analysis uses Chinese firm census data for the manufacturing and service sectors, along with constrained...

A growing literature suggests that high-income countries export high-quality goods. Two hypotheses may explain such specialization, with different implications for welfare, inequality, and trade policy. Fajgelbaum, Grossman, and Helpman (2011) formalize the Linder hypothesis that home demand...

Based on their ability to facilitate interdependencies across the borders of national and regional markets, multinationals enterprises (MNEs) act as the key drivers of world trade and investment activities. While recent global challenges additionally highlight the need to explain and assess the...

How are the dynamics of foreign and domestic sales correlated at the firm level? The question is relevant in that the sign of the correlation shapes the international transmission of shocks and the effects of policy measures. From a theoretical perspective, the correlation could be either zero,...
