Responsabilita' sociale d'impresa e abitudini alimentari: contributo di Coop nella creazione di valore per i cittadini, per il territorio e i prodotti tipici di qualità

I cambiamenti e le innovazioni sociali, che hanno caratterizzato il secolo scorso, hanno generato mutamenti significativi nella struttura dei consumi, legati in particolare a una maggiore consapevolezza dei consumatori e allo scoppio della crisi economica. Assume sempre maggiore importanza, all’interno delle politiche di brand management, il ruolo della Responsabilità Sociale d’Impresa, che spinge la Grande Distribuzione Organizzata a proporre prodotti con più alti standard qualitativi e di sicurezza. Il caso analizzato è quello della linea biologica ViviVerde Coop, la cui offerta di prodotti biologici a private label ha avuto un impatto molto positivo sul mercato. L’analisi dell’elasticità della curva di domanda di alcuni di questi prodotti nel periodo gennaio 2010-maggio 2012 rivela diversi valori positivi e maggiori di 1, indice del fatto che il prezzo non abbia avuto effetti negativi sulle vendite dei prodotti considerati. Tale evidenza risulta rilevante proprio in un periodo di profonda crisi economica che ha interessato, in modo significativo, anche i consumi alimentari.

Clustering of variables around latent components: an application in consumer science

The present work proposes a method based on CLV (Clustering around Latent Variables) for identifying groups of consumers in L-shape data. This kind of datastructure is very common in consumer studies where a panel of consumers is asked to assess the global liking of a certain number of products and then, preference scores are arranged in a two-way table Y. External information on both products (physicalchemical description or sensory attributes) and consumers (socio-demographic background, purchase behaviours or consumption habits) may be available in a row descriptor matrix X and in a column descriptor matrix Z respectively. The aim of this method is to automatically provide a consumer segmentation where all the three matrices play an active role in the classification, getting homogeneous groups from all points of view: preference, products and consumer characteristics. The proposed clustering method is illustrated on data from preference studies on food products: juices based on berry fruits and traditional cheeses from Trentino. The hedonic ratings given by the consumer panel on the products under study were explained with respect to the product chemical compounds, sensory evaluation and consumer socio-demographic information, purchase behaviour and consumption habits.

Producers' Perceptions and Consumers' Behaviour Toward Certified Beans from Integrated Production (IP) in the Brazilian Central Region

Integrated production (IP) is part of the Brazilian government program to promote sustainable agricultural production. IP ensure minimum food quality standards for domestic market, and export. Furthermore, IP is considered a good option to reduce negative environmental impacts of intensive crops in tropical Savannas, including common beans, as a Brazilian staple food. Although its advantages, and the government’s effort to promote IP, few growers are adopting IP. Maybe, the perception about IP usefulness and/or its ease of use is not too clear. Moreover, the production sector is driven by market signs, and there is few information on the consumer's preferences toward IP certified products in Brazil. In this study, we sought to identify some critical factors that can influence the IP adoption in beans' production. Moreover, we sought to verify the consumers’ perceptions and intention of purchasing IP certified beans (hypothetical product). This report comprises four chapters: (1) an introduction illustrating the context in which the research was based; (2) the results on the study of IP adoption based on the Technology Acceptance Model (TAM); (3) the choice experiment results applied to identify consumers preferences and willingness-to-pay (WTP) for IP label; (4) the results on the Theory of Planned Behaviour (TPB) applied to identify consumers’ perception toward IP certified beans. This research contributes with rich information for the beans’ supply chain, providing several insights to growers, retail and other agents, including policy makers. Beans’ production sector seems to be positively intentioned to adopt IP, but further studies should be conducted to test other adoption indicators using TAM model. Surveyed consumers are willing to pay a premium price for IP labelled beans. They showed a positive attitude toward purchasing IP labelled beans. It is an important information to motivate production sector to offer certified beans to the market.
