Export Diversification: What's behind the Hump?
The paper explores the evolution of export diversification patterns along the economic development path. Using a large database with 156 countries over 19 years at the HS6 level of disaggregation (4,991 product lines), we look for action at the intensive and extensive margins. We find a hump-shaped pattern of export diversification similar to what Imbs and Wacziarg (2003) found for…

In Search of Market Access: Why the Doha “Plan B” for December 2011 is likely to fail Erosion from Rules of Origin (Part II)
Once again the Doha Round negotiators are struggling to reach an agreement, this time by mid-December 2011 on a “plan B” package that would give increased market access to the Least Developed Countries (LDCs) under simplified rules of origin (RoO). We argue that in spite of some simplifying reforms by the EU and the US, administrative costs associated with establishing origin will…

In Search of Market Access: Why the Doha “Plan B” for December 2011 is likely to fail Effective Market Access (Part I)
Once again the Doha Round negotiators are struggling to reach an agreement, this time by mid-December on a “plan B” package that would give increased market access to Least Developed Countries (LDCs) in the form of duty-free-quota free (DFQF) access accompanied by simplified rules of origin. Estimating ‘effective market access' to the two largest ‘preference-givers', the US…

A New Measure of Tariff Preference Margins Adjusted for Import and Domestic Competition
This paper provides a new theoretically-derived measure of preference margins at the product level, that takes into account competition across exporters as well as competition with domestic producers on a given market. This indicator is derived for differentiated goods under imperfect competition, in a frame-work extended from Ottaviano, Tabuchi and Thisse (2002). We compute our…

The Doha Round and Market Access for LDCs: Scenarios for the EU and US Markets
Least developed countries (LDCs) hoped that the DOHA round would bring them greater market access in the Organization for Economic Cooperation and Development countries than for non-LDCs. Using HS-6 tariff level data for the United States 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…

Measures of export diversification
How export patterns vary across time and countries has become a subject of intense descriptive analysis in recent years. The originality of our work is to compute usual diversification indices using a very large and disaggregated dataset on exports. Export data is from UNCTAD’s COMTRADE database at the HS6 level (4’991 lines).

Has distance died? An update
Contrary to expectations, evidence of a death of distance has eluded numerous estimations in the popular gravity model of trade: estimates of the coefficient of distance are markedly higher in studies with recent data. This column shows that this is only so for the poorer countries who are trading with geographically closer partners. This regionalization of trade for low-income…

The Distance Effect and the Regionalization of the Trade of Low-Income Countries
The “distance effect” measuring the elasticity of trade flows to distance has been to be rising since the early 1970s in a host of studies based on the gravity model, leading observers to call it the “distance puzzle”. We review the evidence and explanations. Using an extensive data set of 124 countries over the period 1970-2005, we confirm the existence of this puzzle and identify…
