La responsabilité sociale et environnementale de l'agriculture et des entreprises agro-alimentaires est aujourd'hui largement remise en question. Ce secteur économique est à la croisée des chemins compte tenu des nombreuses externalités environnementales de l'activité du secteur, des...

Cet article ré-examine la réglementation environnementale, sous l'hypothèse additionnelle que les technologies et services de dépollution sont fournis par une industrie de l'environnement en concurrence imparfaite. On montre que chaque instrument de réglementation (taxes et quotas sur les...

This paper documents a decreasing trend in the geographical concentration of EU agro-food imports. Decomposing the concentration indices into intensive and extensive margins components, we find that the decrease in overall concentration indices results from two diverging trends: the pattern of...

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...

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 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...

Building on earlier work by Estevadeordal, we construct a synthetic index (R-index)intending to capture the restrictiveness on market access due to product specific rules of origin (PSRO)that apply at the tariff-line level. The R-index is constructed for rules of origins under NAFTA and under...
