We collect extensive data on worldwide trade by transportation mode and use this to provide detailed comparisons of the greenhouse gas emissions associated with output versus international transportation of traded goods. International transport is responsible for 33 percent of world-wide...

We model demand for quality differentiated goods to derive a relationship between trade costs and the quality composition of trade. Detailed data on traded goods' prices, quantities and shipping costs for many importers and exporters are used to test these predictions. These data provide a...

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...

Purchasing goods from distant locations introduces a significant lag between when a product is shipped and when it arrives. This is problematic for firms facing volatile demand, who must place orders before knowing the resolution of demand uncertainty. We provide a model in which airplanes bring...

New measures have opened up insights into the extent and complexity of global production networks. The chapters in this timely book deploy new tools to understand how global value chains change the nature of global economic interdependence, and to assess how that in turn changes our...
