Potable intellectual property: WTO TRIPS and EU geographical indication wines

The World Trade Organization (WTO) protects geographical indication (GI) wines such as Bordeaux and Chianti. However, there is scant empirical evidence on the effectiveness of this protection. Our triple difference panel data analysis of EU wine exports from 1995 to 2019 finds a significant effect. When countries join the WTO, their import of GI wines increases by about 25% more than non-GI wines, compared to non-joiners. Our findings suggest that specific trade provisions matter and that the EU policy of also including wine GIs in bilateral agreements is an attempt to further improve enforcement of GI protection in third countries.
