Do Preferential Trade Agreements Matter for Biodiversity Conservation?
Julie Lochard (UPEC, ERUDITE)
We provide new evidence on the interaction between trade liberalization and biodiversity conservation. Using a difference-in- differences approach on a large sample of 213 countries over the period 2000-2017, we evaluate the effects of environmental provisions included in Preferential Trade Agreements (PTA) on the adoption of domestic conservation policies. We find that countries signing a PTA with specific environmental provisions increase the coverage of their protected areas. These effects appear mostly in the short run and on the extensive margin. We do not find any impact of the number of biodiversity provisions or of the number of PTAs with provisions. Our analysis also reveals heterogeneity across countries and across provisions.
