We identify in this Paper the level of trade integration between the three largest economic powers of the world, often called the Triad: The United States, the EU and Japan. We focus on measuring possible asymmetries in market access between members of the Triad using border effects between each...

Although average tariffs in Quad markets are very low, tariff peaks and tariff escalation have a disproportional effect on exports from least developed countries (LDCs). Tariff peak products tend to be heavily concentrated in agriculture and food products and in labour-intensive sectors such as...

Most of the large tariff reductions achieved in multilateral trade negotiations have involved tariff-cutting formulas such as the ‘Swiss’ formula. Wide variations in initial tariff rates between active participants, however, call for new approaches under the Doha Development Agenda. This...

We conduct a randomized control trial that generates exogenous variation in the access to foreign markets for rug producers in Egypt. Combined with detailed survey data, we causally identify the impact of exporting on firm performance. Treatment firms report 15-25 percent higher profits and...

This paper develops a method to measure difficulties in market access over a large set of industries and countries (both developing and developed), during the period 1980-2006. We use a micro-founded heterogeneous-consumers model to estimate the impact of national borders on global and regional...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

Although a rich and extensive body of theoretical research on new economic geography has emerged, empirical research remains comparatively less well developed. This paper reviews the existing empirical literature on the predictions of new economic geography models for the distribution of income...

LDCs hoped that the DOHA round would bring them greater market access in OECD countries than for non-LDCs. Using HS-6 tariff level data for the US and the EU for 2004, this paper estimates that, once the erosion from preferential access into the EU to non-LDCs is taken into account, LDCs have...

This paper first briefly describes the role of the WTO and its history. It then lays out a simple bargaining model of international negotiations, which can be used for understanding the Doha round of talks. This simple framework is used to distil and discuss a number of potential explanations...

Contrary to what has been standard in the international trade literature, we argue that firms' access to international markets should not be just reduced to exogenous factors such as trade costs. Instead, we defend that market access can also be endogenous, since firms can affect international...
