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...

Les biens et services de dépollution sont actuellement le plus souvent livrés par une éco-industrie. Cette note reconsidère la taxe pigouvienne dans ce contexte. On montre qu'une taxe optimale sur les émissions polluantes se démarquera du coût social marginal de la pollution en fonction...

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...

Recent years have seen a surge in economic integration agreements (EIAs) and the development of non-tariff measures (NTMs). As a consequence, a growing number of EIAs include provisions on NTMs. This paper focuses on provisions on technical regulations. We investigate whether the technical...

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...

This paper estimates the effective market-access granted under NAFTA in textiles and apparel by combining two approaches. First, we estimate the effect of tariff preferences and rules of origin on the border prices of Mexican final goods exported to the US and of US intermediates exported to Mexico.
