The impact of geographical indications on farms’ performance. An empirical analysis of the EU vineyard sector

Relying on the EU FADN dataset for the period 2004-2020, the reports quantitatively estimates the impact of Geographical Indications (GIs) on the economic, environmental and social performances of GI vineyard farms. The empirical analyses employed the combined matching and difference-in-differences estimation technique, which allows several important sources of bias to be addressed, such as self-selection bias, time-invariant and time-variant systematic differences across farms and functional form misspecification. The estimated results suggest that GIs improve economic performance of vineyard farms. GIs also have some positive impact on social dimension by stimulating higher farm wages, while have statistically insignificant impact on farm employment. In contrast, GIs are found to have rather small impact on environmental performance of farms potentially leading to some reduction of energy use, while having no impact on plant protection use of vineyard farms.
