The contingent equilibrium during imbalanced volcano tourism demand through fee estimation: An empirical analysis of tourism in Mt. Etna
2022
Volcanic sites can be considered strategic areas for conservation and protection policies, but such policies may involve considerable costs However, not only are volcanic sites often integral to the tourism industry and, hence, of potential significant benefit to local economies in general; entrance fee income from tourists can also contribute to management and conservation costs in particular. Nevertheless, seasonal variations in tourism demand, resulting in over-and under-tourism situations, may impact on both the level of income generated as well as on the sustainability of sites Therefore, based on a case study of Mt Etna in Italy, this study considers establishing appropriate entry fee…
Valuing public acceptance of alternative-fuel buses using a Latent Class Tobit model: A case study in Valencia
2020
Abstract The introduction of hybrid electric technology for urban public transportation can be considered a valuable stepping stone to low-carbon mobility. Using the contingent valuation method, a sample of 427 respondents were asked about their willingness to pay for the air pollution reductions associated to a scenario of gradual introduction of hybrid electric buses in Valencia, Spain. Results show that 67% of the respondents are willing to pay extra for the adoption of this electric hybrid technology, being the mean willingness to pay € 0.33 per single bus fare. This would imply a 22% hypothetical increase in current bus fares and shows that public acceptance is critical for the success…
Europeans' willingness to pay for ending homelessness: A contingent valuation study.
2020
The purpose of this study is to assess the utility value European citizens put on an innovative social program aimed at reducing homelessness. The Housing First (HF) model involves access to regular, scattered, independent and integrated housing in the community with the support of a multidisciplinary team. Currently, HF is not implemented by most European countries or funded by healthcare or social plans, but randomised controlled trials have stressed significant results for improved housing stability, recovery and healthcare services use. The broader implementation of HF across Europe would benefit from a better understanding of citizens' preferences and "willingness to pay" (WTP) for med…
Respondent Uncertainty and Ordering Effect on Willingness to Pay for Salt Marsh Conservation in the Brest Roadstead (France)
2017
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…
Urban consumers’ attitudes and willingness to pay for functional foods in Iran: A case of dietary sugar
2017
Growing concerns for the incidence of incurable diseases and high costs of health care have attracted consumers to functional foods in the world. These foods are characterized with health improvement, lower risk of disease incidence and less health hazards. The present work examined consumers’ attitude and willingness to pay for dietary sugar in Rasht city, Iran. The studied sample included 125 citizens of Rasht in spring and summer of 2016 whose size was determined by Mitchell and Carson approach. Results of contingent valuation method on the basis of one-and-one-half-bound choice model revealed that the descriptive variable of bid had negative, statistically significant impact on the acce…
On the value of drovers’ routes as environmental assets: A contingent valuation approach
2013
The aim of this study was to evaluate the non-market benefits resulting from the restoration of an old drovers’ route for recreation uses in Valencia (Spain). The valuation was carried out using the Contingent Valuation Method (CVM) through the elicitation of individuals’ willingness to pay (WTP). Since 52% of the respondents stated a zero WTP response, in order to inform decision-making processes more accurately, special attention was paid to the problem of zero and protest responses, and also to the possible presence of self-selection by those that protested. For the different specifications considered, results suggest that mean WTP estimates are higher for “rural areas” than for “the Val…
Willingness to pay to improve urban water supply: the case of Sucre, Bolivia
2014
In this study the contingent valuation method is applied in order to estimate the willingness to pay (WTP) of the inhabitants of Sucre (Bolivia) for an improvement in the urban water supply system. The study finds that about 55 per cent of households would be willing to pay an increase in their water bill for an improvement in the service. In order to deal with the problem of protest responses and the possible presence of a sample selection bias, a Heckman two-step model was estimated. More specifically, the econometric analysis undertaken reveals that there is no evidence of sample selection bias and that WTP positively relates to the respondents' household income, their level of education…
Estimating the non-market benefits of water quality improvement for a case study in Spain: A contingent valuation approach
2012
Abstract This article addresses an important topic related to the application of the European Water Framework Directive (WFD) in Spanish watersheds. Results on a contingent valuation study, aimed to assess the non-market benefits of water quality improvements in the Guadiana river basin (GRB), are shown. Special attention has been paid to the issue of zero willingness-to-pay (WTP) responses, while addressing the possible presence of self-selection caused by protest responses. The results (i) indicate that sample selection bias is not a problem in our application, (ii) allow us to identify some key determinants of voting behaviour, and (iii) through the use of different econometric models al…
Monetary Valuations of Monumental Trees and Other Natural Resources between Demand for Conservation and Recent Requirements for Outdoor Activities: S…
2011
The focus of this paper is on the valuation of the benefits that local communities living in protected areas may perceive with regard to some specific natural resources, and in particular to Monumental Trees. The current economic crisis which involves countries at world level, leads to think that in the near future the financial resources to be destined for interventions in favour of these environmental goods will be more and more scarce, with the result that most monumental trees will not be protected and this natural heritage will be totally degraded and therefore lost to local communities. Three Sicilian case studies were investigated, two concerning the Madonie Regional Natural Park, an…
A Double-Hurdle model of urban green areas valuation: Dealing with zero responses
2008
Due to the widespread support for public parks and open spaces in urban areas, there is an increasing need to analyse the social benefits that are generated by such amenities. The city of Valencia (Spain) has a large park that can be considered its green backbone due to its transversal layout running along 9 of the 19 districts into which the city is divided. A contingent valuation survey was therefore conducted in order to obtain the non-market benefits derived from the use of this park by the inhabitants of Valencia. In addition, to deal with the large number of zero responses obtained, a Double-Hurdle model was applied. The results show that this model is more appropriate than other, sim…
