Geopolitical conflicts have increasingly been a driver of trade policy. We study the potential effects of global and persistent geopolitical conflicts on trade, technological innovation, and economic growth. In conventional trade models the welfare costs of such conflicts are modest. We build a...

In this paper we study the impact of digitalization on trade costs in 58 economies over the period 2014 - 2018. Improvements in digital connectivity can reduce trade costs through multiple channels, including better access to information, lower transaction costs, the reduced need for business...

This study provides a decomposition of the WTO Global Trade Costs Index into five policy-relevant components: transport and travel costs; information and transaction costs; ICT connectedness; trade policy and regulatorydifferences; and governance quality. The WTO Global Trade CostsIndex is based...

It has become increasingly common to produce goods in a number of geographically dispersed stages linked by international trade. This tendency, known by names such as production fragmentation, processing trade, and vertical specialization, has important implications for the analysis of nontariff...

Trade costs such as applied tariffs, transportation and insurance costs are amplified as they pass through the multiple production steps associated with modern supply chains. This so-called "cascade effect" arises since trade costs accumulate as intermediate goods are imported and then...

The geography of global value chains (GVCs) depends crucially on trade costs between countries hosting various stages of production. Some stages might be more sensitive to trade costs than others. In this paper, we exploit a value-added decomposition of bilateral trade flows to distinguish low...

This paper studies the factors of comparative advantage within global value chains relying on a framework where comparative advantage is measured through the interaction of country and industry characteristics. We find that good institutions give a comparative advantage in the later stages of...

This study analyses the role of Aid for Trade in reducing trade costs in least developed countries (LDCs). The analysis builds on questionnaires and case stories submitted as part of the Aid-for-Trade monitoring and evaluation exercise for the Fifth Global Review of Aid for Trade. Trade costs...

I develop a novel theory of GATT/WTO negotiations. This theory provides new answers to two prominent questions in the trade policy literature: first, what is the purpose of trade negotiations? And second, what is the role played by the fundamental GATT/WTO principles of reciprocity and...

This paper discusses how information and communication technology (ICT) affects the quality and reach of consumer services. These services need to be provided locally, but consist of several components, some of which can be digitised and transmitted over long distances. A general equilibrium...
