Many studies have found that international borders represent large barriers to trade. But how do international borders compare to domestic border barriers? We investigate international and domestic border barriers in a unified framework. We consider a data set of exports from individual US...

Trade data are typically reported at the level of regions or countries and are therefore aggregates across space. In this paper, we investigate the sensitivity of standard gravity estimation to spatial aggregation. We build a model in which initially symmetric micro regions are combined to form...

This paper investigates the sources and size of trade barriers at the industry level. We derive a micro-founded measure of industry-specific bilateral trade integration that has an in-built control for time-varying multilateral resistance. This trade integration measure is consistent with a...

Barriers to international trade are known to be large but because of data limitations it is hard to measure them directly for a large number of countries over many years. To address this problem, I derive a micro-founded measure of bilateral trade costs that indirectly infers trade frictions...
