The value of the certifications of origin: a comparison between the Italian olive oil and wine markets

Abstract

Purpose – The purpose of this paper is to focus on high segments of the Italian olive oil and wine markets. The main goal is to compare the role and the effectiveness of the certification of origin in the creation of value in the two selected markets. Moreover, the authors investigate how different quality clues in the olive oil and wine sectors are related to prices. Design/methodology/approach – To meet the goal the authors estimate two separate hedonic price models where the price of the product is regressed over different quality clues some of which are sector specific and some are common to the two sectors. The models are estimated on data which come from two of the major Italian guides chosen for their well established reputation and for the richness of information. Findings – The results indicate that: product origin and the relative certification schemes play a relevant role in the formation of prices in both markets; while the olive oil price seems to be more sensitive to farm location than to the certification of origin, the opposite happens for the wines; the higher segments of the Italian olive oil market is increasingly sophisticated and follows the main tendencies established in the quality wine markets where many quality attributes are intensely active. Research limitations/implications – First, it should be kept in mind that results for higher market segment may not hold for different segments where relevant quality clues may be different. Second, reader should be aware that comparability of the two samples is constrained by limited data availability for the olive oil sector compared to the wine sector. Originality/value – This study represents one of the first attempts to compare the role of the certification of origin in the creation of value in the Italian agro-food markets.

In search of agri‐food quality for wine: Is it enough to join a geographical indication?

“…The regulation defines two categories for the wine sector: the least demanding, protected geographical indications (PGI), and the most demanding, protected designations of origin (PDO). Compared with PGIs, PDOs are characterized by stronger traceability, stronger connections to the region of origin and less freedom in production rules, and in the blending of grape varieties (Cacchiarelli, Carbone, Laureti, & Sorrentino, 2016; Deselnicu et al, 2013). Within each GI category, country‐specific laws may differentiate further levels.…”

Eleven Monovarietal Extra Virgin Olive Oils from Olives Grown and Processed under the Same Conditions: Effect of the Cultivar on the Chemical Composition and Sensory Traits

“…Olive oil markets are changing rapidly. Monovarietal extra virgin olive oil (MEVOOs) are gaining increasing interest allowing for further segmenting of the market and creating new trends in high market niches [ 1 , 2 ].…”

Extra‐virgin olive oil: are consumers provided with the sensory quality they want? A hedonic price model with sensory attributes

“…In the same fashion, the US market was investigated in which credence attributes were the most valued by consumers . More recently, Cacchiarelli et al . related the price of Italian EVOO mainly to origin of the product, especially from central Italy regions, and to the presence of a Protected Designation of Origin (PDO) certification.…”
