Sustainable production systems have become a relevant issue for consumers in the wine industry. Several studies have revealed that consumers are increasingly interested in organic wine and have attempted to estimate the price premium that consumers would have to pay for this ‘new’ product. The aim of this paper is to assess the role of organic attributes in driving consumer choice, and how consumer socio-demographic characteristics influence the price premium for organic wine. An on-line survey was administrated among Italian wine consumers (N = 317) and an ordinal logistic regression model, based on cumulative probability distribution, was estimated. The results show important differences in the Willingness to Pay (WTP) between different market segments. Younger people have a more positive attitude towards wine with sustainable characteristics, and we found that consumers aged under 50 have a higher WTP. Price is another attribute that affects preferences for organic wine: consumers that state that price is a very important factor in the choice of a bottle are less willing to pay for organic wine. Consumers characterized by a low consumption frequency have a higher WTP for organic wine.

Recently, we witnessed a growing interest in those tourist experiences that focus on the enhancement and promotion of typical local cultures, in particular related to winemaking traditions. In Italy this evidence is also demonstrated by the emergence of events and tours linked to the promotion of Italian wine. It is therefore necessary to pay particular attention to the degree of satisfaction expressed by visitors with regard to the services currently offered within the framework of their wine tourism experience. The present research applies a study on customer satisfaction in the area of the Prosecco district, in the Veneto Region in Italy. The aim of the paper is to understand, by the use of a mixture model denoted as the Covariate Uniform Binomial Model, whether and to what extent the high degree of quality perceived by respondents depends on factors related to personal experience rather than on the circumstances in which the interviews were conducted. Results show that socio-demographic variables have a great impact on wine tourism behaviour. As a consequence, the possibility of creating segments of consumers based on socio-demographic characteristics and consumer behaviour shows the need to consider different marketing policies to satisfy the different needs of tourists that emerged.

The 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.
