Measuring the WTP for Recreation and Biodiversity Protection Programs

This paper focus on a contingent valuation (CV) exercise as to compute estimates for the willingness to pay (WTP) for recreation and biodiversity benefits of a Natural Park in Portugal. The CV survey gathers 1678 respondents and three development policy options. We refer to the Wilderness Areas (WA) tourism development scenario; the Recreational Areas (RA) tourism development scenario and, finally, a scenario version which is characterised by the tourism development of both WA and RA. The results show that the respondents evaluate the WA and RA differently. However, we find no statistical difference between the WTP for the WA and the WTP for the WA jointly with the RA. The last result can be interpreted as an indicator of an eventual presence of warm-glow in the WTP responses.

Testing the Validity of WTP values from a Contingent Valuation Survey in Portugal

This paper explores the statistical validity of the willingness to pay (WTP) answers from a contingent valuation (CV) survey concerning value assessment of recreation and biodiversity protection programs. Firstly, we use a non-parametric testing approach as to evaluate the whether (a) different information levels concerning the government costs with the Park and (b) different payment vehicles influence the stated WTP responses. Secondly, we use a parametric model specification as to investigate the impact of the elicitation question format on the stated WTP responses. The likelihood ratio test results, at 95% confidence level, confirm the validity of the proposed survey a measurement instrument. Nevertheless, the presence of free riding turns out to be statistically significant in one of the survey versions. The parametric model results suggest that the differences in the mean WTP estimates across the two question formats are not statistically different. Furthermore, the double bounded dichotomous choice model value estimates point out that the WTP for the recreation protection program is lower than the WTP for the biodiversity protection program, thus confirming the importance of non-use value component of the Natural Area.

Towards the Optimal Management of the Northeast Arctic Cod Fishery

The objectives pursued by governments managing fisheries may include maximizing profits, minimizing the impact on the marine ecosystem, or securing employment, which all require adjusting the composition of the fishing fleet. We develop a management plan that can be adapted to those objectives and allows the regulator to compare the long-run profits between the various management options. We apply the model to the case of Northeast Arctic cod, and estimate the cost and harvesting functions of various vessel types, the demand function, and a biological model to provide key insights regarding the optimal management of this valuable fish species.Built Coastal Environment, Natural Coastal Environment, Ecosystem Service Valuation, Geographic Information Systems, Mapping Ecosystem Values, Marine Biodiversity, Scaling up, Spatial Analysis, Spatial Economic Valuation, Value Transfer

Economic Valuation of Oceanographic Forecasting Services: A Cost-Benefit Exercise

This paper provides an assessment of the economic value of the oceanographic services provided by the Mediterranean operational forecasting system, MFSTEP. The main purpose of this exploratory study is to carry out a cost-benefit analysis for different development scenarios, by comparing the costs associated with the project implementation with the private benefits that arise from delivering its products on the market. As far as the costs are concerned, a total cost assessment has been performed by identifying, classifying and estimating the wide range of inputs that have been allocated both to the project development and maintenance. Against this context, a cost questionnaire has been designed and administered to all MFSTEP partners. In addition, the study focuses on an end-users analysis in order to examine end-users’ attitudes and interests for the forecasting products, their needs and satisfaction. As before, we make the use of a survey. Finally, this questionnaire is characterized by exploring the use of the contingent valuation approach so as to address and estimate the private benefits derived from the provision of the MFSTEP products. Estimation results show that the mean willingness to pay for accessing the forecasting products amounts to 65 euro per download. Cost-benefit analysis reveals that, from a market perspective relying on the profit maximisation, a total of 163 downloads per day are required for total maintenance costs recovery, whereas 90 downloads per day are required to recover personnel maintenance costs. Finally, 33 downloads per day are required so as to recover durable equipment maintenance costs.Cost-Benefit Analysis, Contingent Valuation, Survey Design, Willingness to Pay, Cost Assessment, Observing and Modelling Oceanographic System

Is the Value of Bioprospecting Contracts Too Low?

In order to regulate the proliferated bioprospecting and protect the biological diversity in the source countries, the Convention on Biological Diversity (CBD) established a legal framework for the reciprocal transfer of biological materials between the interested parties in bioprospecting activities, subject to the Prior Informed Content (PIC) principles and a set of mutually agreed items on equitable sharing of benefits (CBD 1992, Bhat 1999; Ten Kate and Laird 1999; Dedeurwaerdere 2005). Although interesting and valuable to the cause of conservation, there is a feeling that the ‘price’ being paid under these arrangements is too low. Somehow ecologists argue that, surely, these materials have a greater value than the few million dollars being paid to national conservation organizations for the protection of the areas where the material are located. In this paper we seek to understand better how a biodiversity resource’ use value in production is determined, and how the real value is obscured by the fact that the resource is largely open access. We attempt to analyse how special arrangements, set op top of a basic framework in which the resource open access is limited in what it can achieve and in the ‘price’ that will emerge from any transaction between the buyers of the rights and the sellers of the rights.Access and Benefit Sharing, Convention for Biological Diversity, Bioprospecting Contract, Genetic Resource, Open Access and Welfare Analysis

A Global Map of Coastal Recreation Values: Results From a Spatially Explicit Based Meta-Analysis

The welfare dimension of the recreational services provided by global coastal ecosystems is examined through a meta-analytical regression-based valuation approach. First, we construct a global, state-of-the-art database of stated and revealed preference estimates on coastal recreation, which includes also the grey literature and with the latest entry updated to February 2010. Second, the profile of each of the 253 observations of our dataset, which correspond to individual value estimates, was further enriched with characteristics of the built coastal environment (site accessibility, anthropogenic pressure, level of human development), characteristics of the natural coastal environment (presence of protected area, type of ecosystem, and marine biodiversity richness), geo-climatic factors (temperature and precipitation), as well as sociopolitical characteristics, such as the political stability index. In this context, the proposed meta-analytical valuation exercise explores the spatially explicit dimension of the values building upon Geographic Information System (GIS) tools. GIS are relied upon for the spatial characterization of the valued ecosystems, the determination of the role of spatially explicit variables in the meta analytical value transfer model, as well as for the value transfer exercise. The GIS characterization is observed to be extremely significant in explaining the spatial diversity of the estimates values and underlying explanatory factors. The resulting integrated valuation framework constitutes a worldwide première and it results in the first global map of the recreational value of coastal ecosystems. We argue that the presented global map may play an important role in studying the prioritization for the conservation of coastal areas from a social perspective.Built Coastal Environment, Natural Coastal Environment, Ecosystem Service Valuation, Geographic Information Systems, Mapping Ecosystem Values, Marine Biodiversity, Scaling up, Spatial Analysis, Spatial Economic Valuation, Value Transfer

The quadratic relationship between intangible assets and growth in Portuguese SMEs

This article shows new empirical evidence concerning the growth determinants of SMEs. Specifically, we identify the existence of a quadratic relationship between the level of intangible assets of Portuguese SMEs and their growth. Based on the results obtained here, we conclude that intangible assets represents a catalyst for growth only when accounting for a significant proportion of total assets. A relatively weaker presence of intangibles might in fact inhibit growth.Growth; Intangible Assets; Portuguese SMEs

Application of Technological Control Measures on Vehicle Pollution: A Cost-Benefit Analysis in China

For the past two decades, China has experienced strong, continuous economic growth. At the same time, the number of motor vehicles in China has rapidly increased. As a direct result of such a phenomenon, China has been registering significant increases in air pollution. In spite of recent advances in air pollution control, it remains a serious problem for China’s major cities, and constitutes an important issue in the agenda of its policy makers. The object of this paper is to explore the use of cost-benefit analysis (CBA) to evaluate and rank alternative policy scenarios regarding the control of air pollution emitted by motor vehicles. The empirical analysis carried out relates specifically to the Chinese context, over a twenty year period, from 2001 to 2020, and focuses on emission changes of the following three principal pollutants: CO, HC and NOx.Vehicle, Pollution, CO, HC, NOx, Scenario, Standard, Cost, Benefit, China

The Profile of a “Warm-Glower”: A Note on Consumer’s Behavior and Public Policy Implications

The paper focuses on the ongoing debate on non-market valuation, including the valuation environmental goods, and the opportunity to use contingent valuation for policy guidance. In fact, contingent valuation critics argue that reported willingness to pay answers do not reflect real economic preferences and, for this reason, should not be used in cost-benefit analysis The attempt to contravene such critique finds many supporters. This paper starts from the latter stream of research and adds two original contributions. First, it sheds light on the individual warm glow motivational profile, exploring the empirical relationship between individual’s socio-economic characteristics and warm glow. Second, it discusses some implications of the presence of warm glow for public policy.Economic value, Contingent valuation, Willingness to pay; Latent factor, Consumer motivations, Warm glow, Ego driven warm glow, Social oriented warm glow, Public policy design
