Geographical indications’ prices and marketing margins: the role of group size, longevity and production decisions

Purpose – Geographical indication (GI) labels aim to improving farmers’ and processors’ income. This article studies how characteristics related to GI groups and their reputation (e.g. the producer group size, longevity and production decisions) are related to prices at the origin, final (consumption) prices and marketing margins. Design/methodology/approach – The authors use 8 years of annual data for the Italian Extra Virgin Olive Oil (EVOO) GI market encompassing 46 GI EVOOs. Estimated parameters characterizing the relationship between the GI’s group features and prices (at origin and at consumption) are obtained via Three-Stage Least Squares (3SLS). Findings – Results show that the number of GI operators is related to consumption prices, while is weakly related to prices at the origin. GIs’ age is not associated with higher consumption prices, while origin prices are lower for older GIs compared to younger ones. Higher farmers’ olive/oil conversion rate is associated with lower origin and consumption prices, whereas the extent of vertical integration is related to higher prices at the origin and a higher share of the marketing margins going to producers. Originality/value – To the best of their knowledge, the authors offer the first empirical evidence on how structural characteristics and production decisions of a GI group relate to prices and marketing margins.
