Consumers’ perception of Prosecco wine packaging: A pilot study in Padua and Milan
Full text linkThis paper aims to illustrate and discuss the importance of packaging attributes in the wine market. A survey was conducted in the north of Italy to assess how different attributes affect the probability of choosing a bottle of Prosecco wine. Two hundred face-to-face interviews based on a structured questionnaire were administered in Milan and Padua supermarkets to elicit preferences. Each respondentranked three new bottles of Prosecco wine and expressed the importance of different packaging characteristics in its choice.Product attributes include Label’s form, Label’s colours, the Label in its entirety, the Writing “Prosecco”, the Band on the bottle’s neck and the Bottle’s shape. The interviews allowed us to recognise the bottle customers found the most attractive, and rank-ordered logistic regression was able to disentangle whichpackaging characteristic led to their decision
Consumers' Willingness to Pay for Quality and Safety in Clams
Full text linkThe aim of the research is to estimate the potential demand for certified clams in Italy and to investigate the determinants of maximum amount that respondents are willing to pay for this product. Quantitative analysis was used based on 1,067 face-to-face interviews collected in 3 Italian regions in the north bordering the Adriatic Sea (Friuli-Venezia Giulia, Veneto, and Emilia-Romagna) carried out during 2008. The consumers' willingness to pay (WTP) is measured using a contingent valuation method. In order to estimate separately the determinants of the probability that respondents are willing to pay and the maximum that they are willing to pay, a generalization of Tobit model was adopted. The results indicate that consumers are willing to pay a premium price mainly to purchase better quality products. The research provides some initial insight into consumers' WTP that can be useful for certified fish farming. © 2014 Taylor & Francis Group, LLC
