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...

Alternative approaches to estimating the effects of non-tariff measures (NTMs) on trade flows are discussed and evaluated critically. Recent econometric studies point to three results: (i) NTM restrictiveness measures based on an aggregate of ‘core’ NTMs are more restrictive than existing...

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. We find evidence of diversification followed, in the very last years of the sample period (post-2000), by a...

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...

The paper explores the evolution of export diversification patterns along the economic development path. Using a large database with 159 countries over 17 years at the HS6 level of disaggregation (4’998 product lines) we look for action at the “intensive” and “extensive” margins...
