Consumer perspectives on coastal fisheries and product labelling in France and Italy
Abstract The term ‘coastal fisheries’ designates a form of fishing which is under heavy pressure due to competition by large-scale high sea fishing. Setting up markets for seafood from coastal fisheries might offer possibilities of product differentiation when appreciated by consumers. The aim of this research is to analyse the potential of marketing seafood from coastal fisheries by investigating consumers’ perception of coastal fisheries and their attitudes towards a label for coastal fishery products in France and Italy. This research combined qualitative (focus groups) and quantitative methods (online survey) in two different steps. ‘Coastal fisheries’ were mainly perceived positively, …
Dealing with preference uncertainty in contingent willingness to pay for a nature protection program: A new approach
In this paper, we propose an alternative preference uncertainty measurement approach where respondents have the option to indicate their willingness to pay (WTP) for a nature protection program either as exact values or intervals from a payment card, depending on whether they are uncertain about their valuation. On the basis of their responses, we then estimate their degree of uncertainty. New within this study is that the respondent's degree of uncertainty is "revealed", while it is "stated" in those using existing measurement methods. Three statistical models are used to explore the sources of respondent uncertainty. We also present a simple way of calculating the uncertainty adjusted mea…
L'espace de liberté comme mesure synthétique du développement territorial durable
By discussing the concept of development itself, authors propose two synthetic indexes relying on estimation of potential: Development Space Value and Development Space Creation Under the weak hypothesis that any successful development improves future possibilities, changes in potential are a good development measure. In their path, authors show how development space is tied with freedom: a shrink in it results mechanically in indexes fall. So, "sustainable" and "economic" become two sides of same piece rather than enemies. Reliable in simulations, the approach is to be tested in real conditions, to verify full data availability and to secure calculating methods.
The influence of ecolabels and environmental information on fishery and aquaculture consumption
This paper investigates whether the exhibition of sustainable information (i.e., eco-labeling) influence the consumption of fishery and aquaculture products. Using data from the Eurobarometer survey (ebs-95.1) we explore the consumers’ environmental attitudes by tracking the trend in consumption of seafood products before/after the pandemic situation, with a focus on the products showing ecolabels.
Respondent Uncertainty and Ordering Effect on Willingness to Pay for Salt Marsh Conservation in the Brest Roadstead (France)
International audience; This paper explores the potential link between the sensitivity of willingness to pay (WTP) to the order of presenting bid amounts in contingent valuation questions (ordering effect) and respondent uncertainty. The resource being valued is a public project to protect salt marshes against the spread of an invasive aquatic plant in the Brest roadstead (France). Valuation uncertainty is captured through a variant of payment card format where respondents are given the opportunity to report their WTP as either a single value (Option A) or an interval of values (Option B). The ordering effect is tested using both parametric models that ignore and control for the potential s…
A convergent validity test within the payment card format using simulation techniques
International audience; A convergent validity test is performed between two groups of versions of the payment card format. The first group, the classic payment card (CPC), asks respondents to report their willingness to pay (WTP) as a point from a list of amounts, and then treats each WTP response as an interval. The second group generates WTP data that may contain both single point and interval values. It includes the two-way-payment ladder (TWPL) (respondents have to tick amounts they would definitely pay and cross amounts they would definitely not pay), and point-interval payment card (PIPC) (respondents have to tick their WTP as either a point or an interval). The test is conducted usin…
Dominare le nuove sfide della trasformazione digitale: dagli strumenti alla strategia
For two decades now, digitalisation processes have been transforming our societies and our economic systems. The world of cultural heritage is no exception. Essentially perceived as a technical innovation, digitization appeared (pre-Covid) as the natural evolution of practices, with particular emphasis on aspects related to better conservation of heritage. The Covid-19 pandemic represented a significant, albeit disorderly, rupture and acceleration of this path, in particular in response to the need to adapt to the restrictions on social life and mobility that characterized the 2020-2021 period. Today, in the post-pandemic phase, it is important to analyze the new conditions in order to prep…
