There is widespread evidence that geographical borders reduce trade. This paper presents a theoretical model capable of providing a succinct comparison of three broad forms of trade barriers involving i) trade costs, ii) localized tastes, and iii) information frictions. Despite being...

In this paper, we examine an innovative postal export regime that involves both a streamlining of export procedures and provision of intermediation services to investigate how firms' react to changing trade costs and whether and how these firms learn. In so doing, we use a unique dataset that...

We examine transaction-level Peruvian import data to show that firms are subject to significant costs of port-of-entry delays. At the transaction level, we observe the time it takes a shipment to clear each step in the entry process. Our theory shows conditions under which observed entry times...

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (2000) that trade costs are the key to explaining the so-called Feldstein-Horioka puzzle. Using a gravity framework in an intertemporal context, we provide strong support for the hypothesis and we reconcile our results with...

Trade facilitation policies intend to simplify administrative processes and accelerate the handling of shipments across borders. Recent research shows that these policies have substantial effects on trade flows. In this chapter, we discuss what the existing evidence for trade implies for the...

The Internet greatly increases firms' potential to produce new goods and service for new markets. The Internet is also having a dramatic impact on services, especially in the retail, trade and finance sectors, by enabling firms to digitize their products and deliver them over long distances....

Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

Trade facilitation policy focuses on accelerated and transparent shipment processing to reduce trade costs. A common measure to evaluate processing frictions is the time it takes to import. In this paper we translate import processing times to costs. Our theory considers that shipment processing...

While much has been said about the need to promote intraregional trade and the importance of reducing associated trade costs, quantitative estimates of such costs have been lacking. In this paper a new comprehensive measure of international trade costs is applied to calculate, according to...

This paper establishes that production unbundling has coincided with an inscreasing role of input costs in shaping the pattern of comparative advantage. I show that the wedge in the cost of the input bundle across countries in a multisectoral Ricardian model is given by a composite index of...
