A statistical analysis of consumer perception of wine attributes
No full textAs for other food products wine is characterized by so called intrinsic attributes, relating to taste, color, aroma, and extrinsic attributes such as labeling information, price, region of origin, brand, packaging. The purchase decision is, therefore, originated by an inferential process which is aimed to assess wine quality from the extrinsic attributes. All the other features can, in fact, be judged only during consumption.
This contribution discusses how CUB models can be applied in order to identify: i) fundamental elements which affect purchase
decisions, ii) significant similarities and differences in the overall judgements expressed by raters on various attributes, iii) the dependence of ratings from consumers’ profile
Strategie d'impresa e qualità nel comparto degli oli extra - vergini di oliva molisani
No full textRecent approaches about food quality have stressed the social processes by which “quality conventions” prevailing on the market are achieved. The present work investigates
these conventions on the supply side, focusing on the “styles” characterizing the management of a group of firms.
More specifically, the research analyzes a group of oil-press plants localized in Molise, an Italian region the name of which is also the “brand-name” of a PDO recently registered
by EU. In the first part the essay outlines the scenario of both olive oil market and local context. In the second section the paper shows the results of a direct survey.
Applying factorial analysis to the data collected in the survey, four main “quality factors” were identified: safety and health; localization and scale; product differentiation; technological heritage. On the basis of these factors it was
possible to point out three main styles characterizing the sample firms: the “endogenous”, the local, and the “fordistic”

The reuse of sediments dredged from artificial reservoirs for beach nourishment: Technical and economic feasibility
Full text linkSedimentation has significant impacts on the useful capacity of an artificial reservoir, a resource to preserve. Interventions of dredging are therefore often unavoidable, even because decommissioning of dams is often impossible in many contexts and entails high costs. Dredging generates an undesired accumulation of materials that represent an environmental cost, but that could be used as intermediate products in other processes, such as beach nourishment. The study develops a method for the evaluation of the feasibility of an investment aimed at coastal nourishment with sediments dredged from artificial reservoirs. The method considers the set of technical conditions that make such use possible. The presence of economies of scope, with environmental diseconomies utilized as joint product, modifies the evaluation approach. The results of the approach show a possible environmental and economic sustainability of the proposed investment even in the presence of highly unfavorable scenarios. The study applies the feasibility appraisal to the case of the Guardialfiera reservoir in Molise, Italy
Is green harvesting a useful instrument to solve market problems in the wine sector? Some lessons from Sicily
No full textThe green harvesting (GH) policy measure has been introduced in Italy starting from the 2009/2010 wine season, with the goal of preventing market crises by reducing the yield of a given parcel to zero. In the 2010-2012 period, almost 85% of the national expenditure and about 81% of European Union (EU) expenditure for this measure have been showered on Sicily. This paper, after examining the application of GH in this Region, explores the motivations of 300 vine growers of Western Sicily for taking part, or refusing to do so, in the GH measure. The survey shows the contrasting nature of the opinions that the implementation of GH has caused among the interviewed sample. In fact, on the one hand we have evidence of the farmers’ desire to secure for themselves a guaranteed income, following the typical logic of accepting state assistance and subsidization. On the other hand, we found out a determination, in some producers, not to join in the GH even in the future, justified by factors connected with entrepreneurial culture and ethics. Finally, the statistical model shows that the decision to join is strongly connected to being part of a specific value system
The importance of wine attributes for purchase decisions: A study of Italian consumers' perception
No full textThe importance of extrinsic and intrinsic attributes of wine for purchase decisions is the object of a lively debate. As a matter of fact, in recent decades, the shift of consumption motivations from nutritional purposes to drinking for pleasure has caused a persistent decrease in the overall demand. However, the increasing number of product varieties and brands of domestic and imported wine, as well as the increased diversity in wine styles and prices, make the identification of wine purchase drivers difficult. This article investigates the importance of product attributes for Italian consumers when choosing wine. Specifically, a class of statistical models for ordinal data, namely CUB, is taken into consideration. This type of model allows the comparison and clustering of the rating distributions that consumers express about wine features and the detection of significant similarities and differences. In addition, this technique generally helps to relate the subject's preferences to covariates which typically summarize the socio-demographic profile, the purchase and consumption behavior. © 2012 Elsevier Ltd
