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...

The aim of this paper was to assess the effect of Kenya's domestic trade regulations on the growth of wholesale and retail firms in Kenya. To achieve the study objective, the existing domestic trade regulatory framework was reviewed, and policy gaps were identified. Further, a cross-sectional...

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....

"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...

Using new data on linguistic diversity across and within countries, we examine novel channels though which language affects trade patterns and economic welfare. We find that linguistic similarity within a country accounts for about 10 percent of estimated ‘home bias’, demonstrating the...

La teoría económica sugiere incluir el comercio interno al estimar un modelo de gravedad estructural. Esta inclusión permite identificar parámetros que no pueden ser estimados si tomamos en consideración solamente los flujos de comercio internacional. Sin embargo, el comercio interno puede...

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...

Das Wettbewerbsrecht umfasst alle Regeln, die der Abwehr staatlicher und privater Eingriffe in den Wettbewerb sowie dem Ausgleich negativer Folgen fehlenden Wettbewerbs dienen. "Wettbewerbsrecht und Marktregulierung" analysiert in Band 1 unter Einbezug ökonomischer Erkenntnisse die...

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 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...

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...

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 distributing establishments. This allows us to quantify the normally unobservable forces that determine firm boundaries; which transactions are mediated by ownership control, as opposed to...
