The estimated coefficient of distance on the volume of trade is generally found to increase rather than decrease through time using the traditional gravity model of trade. This distance puzzle proved robust to several ad hoc versions of the model using data for 1962-96 for a large sample of 130...

The effective market access granted to textiles and apparel under the North American Free Trade Agreement (NAFTA) is estimated, taking into account the presence of rules of origin. First, estimates are provided of the effect of tariff preferences combined with rules of origin on the border...

This paper builds on theoretical predictions that show that gains from regional integration are unevenly distributed between resource rich and poor countries. It explores the effects of different integration schemes in the Middle East and North Africa. The results suggest that within the Pan...

This paper explores the evolution of OECD imports over time, measuring their concentration across origin countries at the product level. The authors find evidence of diversification followed, in the very last years of the sample period (post-2000), by a slight re-concentration. This...

This paper explores the evolution of OECD imports over time and as a function of income levels, measuring the concentration of those imports across origin countries at the product level. The authors find evidence of diversification followed, in the last years of the sample period (post-2000), by...

It has been widely argued that, with the decline in trade costs (for example, transport and communication costs), the importance of distance has declined over time. If so, this would be a boon for countries located far from the main centers of economic activity. The authors examine the evolution...

With preferential trade agreements on the rise worldwide rules of origin—which are necessary to prevent trade deflection—are attracting increasing attention. At the same time, preference erosion for Generalized System of Preferences (GSP) recipients is increasing resistance to further...

To become operational, the African Continental Free Trade Area (AfCFTA) must harmonize Rules of Origin (ROO) across Africa's Preferential Trade Agreements (PTAs) along two dimensions: regime-wide rules and product-specific rules. This paper describes and evaluates these ROO across the major...

African countries are negotiating the African Continental Free Trade Area with the aim to spearhead global value chain (GVC) trade among African countries as a driver for robust economic growth. This paper evaluates the participation of Sub-Saharan African Regional Economic Communities (RECs) in...
