Meeting the environmental challenge of port growth: A critical appraisal of the contingent valuation method and an application to Valencia Port, Spain

2012

In order to support effective policy-making, this research is aimed to emphasise the need of measuring the negative impact - or external costs - resulting from port growth. Considering the non-market nature of these external costs, a critical appraisal of the Contingent Valuation method is made paying special attention to the problem of hypothetical bias and the suitability of a willingness to accept (WTA) scenario for damage assessment. Finally, the results of a case study, conducted in Valencia (Spain), are presented with the intention of paving the way for future research in this specific context of port growth and negative externalities. In particular, results indicate that the average …

To Pay or Not to Pay: Competing Theories to Explain Individuals’ Willingness to Pay for Public Environmental Goods

2010

Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG geförderten) Allianz- bzw. Nationallizenz frei zugänglich. This publication is with permission of the rights owner freely accessible due to an Alliance licence and a national licence (funded by the DFG, German Research Foundation) respectively. Several theories have been proposed in an attempt to explain individuals’ willingness to pay (WTP) for public environmental goods. While most studies only take into account a single theory, this article discusses competing theories. These include, in addition to a basic economic model, the theory of public goods, Ajzen’s theory of planned behavior, and Schwartz’s norm-activation…

Estimating willingness to pay for desalinated seawater: the case of Djerba Island, Tunisia

2017

AbstractWater scarcity can be a growth-limiting factor. Non-conventional water resources, such as desalinated water, represent an alternative means of guaranteeing access to water while reducing water stress. In this study, a contingent valuation survey carried out in Djerba Island, Tunisia, allows the joint modelling of two decisions: societal support for the construction of a desalination plant and households’ willingness to pay for desalinated water. To the best of the authors’ knowledge, no study to date has addressed this relationship. We find that although a clear majority of households are in favour of using desalinated water, far fewer are willing to pay for it. The article conclude…

Port–City Relationship and the Environment: Literature Survey and Methodological Approach for Project Appraisal in Presence of Environmental External…

2015

AbstractIn times of increasing environmental awareness, the port–city relationship has gained new meaning because ports have been seen as the origin of both negative and positive externalities affecting public welfare. While the former are the result of port expansion, the latter are the result of transforming obsolete port areas into recreational facilities. Therefore, to support effective policymaking, this paper considers the following question: What is the scope of economic valuation of these externalities in the context of port-project appraisal? Considering their nonmarket nature, which makes economic valuation more difficult, a contingent valuation method is introduced as an economic…

The nonmarket benefits of redeveloping dockland areas for recreational purposes: the case of Castellón, Spain

2003

As a consequence of the decline of central harbour sites and the relocation of port activities to the outskirts of cities, today waterfront redevelopment has become a key issue in the urban revitalisation policies of port cities. Although we are aware that city-port regeneration has strong links with the real estate market, our purpose here is very different. In particular, the contingent valuation method (CVM) has been applied in order to obtain the nonmarket benefits of the environmental and urban improvements derived from redeveloping some port-related areas for recreational and leisure purposes in the city of Castelloèn, Spain. To date, no previous study has attempted to apply this meth…

Estimating the non-market benefits of an urban park: Does proximity matter?

2007

Abstract There is increasing and widespread public support for public park provision in urban areas given that they provide an array of different recreational activities enhancing the citizen's quality of life. A contingent valuation survey of 900 randomly chosen inhabitants was undertaken in Valencia (Spain) to estimate the non-market benefits derived from the provision of a new urban park where there is currently an old train station. In conducting our study we distinguished between the districts of the city more and less affected by the project according to the proximity to the future park. Our main finding is that the mean willingness to pay (WTP) is considerably higher for people who l…

Contingent Valuation Measurement for Staging the Olympic Games: The Failed Bid to Host the 2018 Winter Games in Munich

2020

In the past decade, well-planned bids for hosting Olympic Games failed due to a sudden lack of a support by the population. Therefore, we study both the determinants of people’s willingness to pay (WTP) to host the 2018 Winter Olympic Games in Munich and the changes of respondents’ attitudes and WTP over time. The results from three surveys in 2009, 2010 and 2011 demonstrate that both the perception of the public benefit of the Olympic Games and the general interest in sport have a positive influence on WTP. Moreover, attitudes vary over time, indicating that external factors influence the population’s evaluations of, and appreciation for, hosting of Olympic Games (e.g. media reports). In c…

Monumental trees and their existence value: the case study of an Italian natural park

2015

The paper deals with the evaluation of the existence value of monumental trees in a protected area. Financial resources to be destined for protection interventions have been decreasing more and more, with a high risk of losing this natural heritage. A Contingent Valuation Method (CVM) survey was carried out among the Madonie Park (Sicily, Italy) resident households to evaluate the existence value of monumental trees of the nature trail named "Piano Sempria-Piano Pomo", represented by a population of "Giant hollies" and by 7 other individual trees. These are the main results of the CVM survey: the overall response rate was 40%, individual average WTPs ( Willingness To Pay ) were €12.37 for t…

Estimación del valor económico de la calidad del agua de un río mediante una doble aproximación: una aplicación de los principios económicos de la Di…

2011

El principal objetivo de la Directiva Marco del Agua de la Unión Europea es logar un “buen estado†de las aguas europeas para el año 2015 mediante una combinación de diferentes medidas. En este estudio, dos métodos de preferencias declaradas, el método de valoración contingente y el método de ordenación contingente, han sido aplicados para obtener la valoración económica de una hipotética mejora de la calidad del agua de un río. La comparación de las dos metodologías muestra que las valoraciones obtenidas con el método de ordenación contingente son considerablemente mayores que las obtenidas con la valoración contingente. Por último, los valores estimados se agregan para obtener una apro…
