Problems in valuing the benefits of biodiversity protection   总被引:13,自引:2,他引:13  
This paper considers two problems in valuing the benefits of biodiversity protection. These are, firstly, that preferences for biodiversity protection may be lexicographic rather than utilitarian. The more individuals for whom this is true, the less is cost-benefit analysis validated as a means of decision making for biodiversity protection, since lexicographic preferences are incompatible with the Kaldor-Hicks Compensation Test. Secondly, people may be poorly informed about the meaning of biodiversity, complicating the use of contingent valuation as a means of measuring preservation benefits. This paper first discusses the meaning of biodiversity, and trends in diversity over time. We offer some empirical evidence with regard to lexicographic preferences; consider the implications of having poorly-informed consumers; and then report the results of a contingent valuation study of biodiversity protection with varying levels of information. We find that willingness to pay for biodiversity protection increases with the level of information provided.We thank David Pearce, participants at a seminar at University College London, and two referees for comments on earlier versions of this paper.  相似文献

Agricultural support is increasingly flowing into the maintenance and improvement of landscape quality. While variations in the demand for landscape protection have been successfully attributed to variations in socio‐economic characteristics, the effect of the local landscape setting as a potential determinant of environmental preferences has received less attention. A framework is formulated that describes public support for regional landscape protection as a function of socio‐economic variables and land use patterns. Models are then estimated using detailed local land use statistics and voting records from a referendum on increasing public funding for local landscape amenities protection in the Swiss canton of Zurich. The land use variables represent proportions of open landscape and landscape features that are viewed as particularly valuable for aesthetic and other reasons. Cross‐sectional estimation results suggest that attitudes towards public landscape protection are indeed strongly associated with the local landscape. Approval for protection programmes increased with local scarcity of open space and with the presence of high‐amenity landscape features. Comparison with referendum outcomes on a national‐level environmental issue suggests that the positive association with high‐amenity landscape features may be partly attributable to individuals' self‐selection of residency.  相似文献

The market stall, or valuation workshop, has recently been proposed as a way of addressing some of the limitations of conventional stated preference analysis. In this paper, we attempt to combine a participatory technique similar to the “citizens' jury” with choice modelling, a stated preference technique increasingly being applied in environmental economics. Our focus is on how changes in the context of decision-making (between choices made in isolation and those made in a group setting, and between choices made on individual well being versus collective criteria) produce differences in estimated welfare measures. The empirical context used is that of water quality improvements under the Water Framework Directive, the most significant reform in water legislation in the European Union for many years. We find that the choice experiment format can be successfully implemented in a valuation workshop and that moving from individual to collective choice produces, in this instance, a rather interesting change in both values and preferences which depends on the respondent's interests.  相似文献

We investigate whether government subsidies encourage foreign multinationals to create linkages with domestic suppliers. To this end we use a unique panel dataset of foreign multinationals located in Ireland for which we have exhaustive information on grant receipt. Our results indicate that while European and US foreign plants develop backward linkages independently of grant receipt, multinationals from other parts of the world respond positively to government support. Our results hold even when controlling for the possible endogeneity of grants and the boundedness of the linkage variable. We conclude that governments should not apply a “one‐size‐fits‐all” approach to incentivizing foreign multinationals.  相似文献

In this paper, we investigate the use of geographically weighted choice models for modelling spatially clustered preferences. We argue that this is a useful way of generating highly‐detailed spatial maps of willingness to pay for environmental conservation, given the costs of collecting data. The data used in this study come from a discrete choice experiment survey of public preferences for the implementation of a new national forest management and protection programme in Poland. We combine these with high‐resolution spatial data related to local forest characteristics. Using locally estimated discrete choice models we obtain location‐specific estimates of willingness to pay (WTP). Variation in these estimates is explained by characteristics of the forests close to where respondents live. These results are compared with those obtained from a more typical, two stage procedure which uses Bayesian posterior means of the mixed logit model random parameters to calculate location‐specific estimates of WTP. We find that there are indeed strong spatial patterns to the benefits of changes to the management to national forests. People living in areas with more species‐rich forests and those living nearer bigger areas of mixed forests have significantly different WTP values than those living in other locations. This kind of information potentially enables a better distributional analysis of the gains and losses from changes to natural resource management, and better targeting of investments in forest quality.  相似文献

In this paper, we apply random utility modelling techniques to rock‐climbing in Scotland. Attributes relevant to choices over rock‐climbing sites were identified from focus groups with climbers, along with a categorisation of principal climbing areas. A survey of climbers yielded 267 responses, which were then used as the basis for modelling. We compare a standard multi‐nominal logit model with a random parameters approach, and look at seasonal differences in behaviour, and at the implications of different treatments of travel time. The random utility models showed that most of the attributes selected were significant determinants of choice. Welfare estimates of changes in site attributes are presented, which are relevant to policy choices currently facing land managers.  相似文献

We compare the performance of Northern and Southern multinationals in Sub-Saharan Africa, and contrast it with local firms in the host country. Employing unique firm level data for 19 Sub-Saharan African countries, we show that firms receiving FDI outperform domestic ones, while the origin of the foreign investor is of minor importance. We use three different definitions of “South” to compare Northern and Southern FDI. Overall, we do not find strong differences in terms of firm productivity growth between Northern and Southern FDI, irrespective of how the latter is defined. However, we find that employment growth is generally higher for firms receiving FDI from other African investors as compared to Northern FDI, and they also receive more technology transfer from their parent company abroad.  相似文献

Invasive pests and diseases in trees impose a range of costs on society related to reductions in timber values, impacts on recreational opportunities and effects on forest biodiversity. These costs need to be considered when assessing control options and developing public policy. We investigate the preferences and willingness to pay of the UK general public for a range of forest disease control measures using a choice experiment with a sample of 605 people. Respondents were relatively well informed about general tree disease‐related issues, such as causes and general measures to minimise the risk of disease spread. They were less knowledgeable about specific tree diseases, with Dutch elm disease and chalara ash dieback being the most well known. We find that disease control programmes in publicly‐owned forests and forests owned by charitable trusts are more likely to be supported by the public than equivalent control programmes in privately‐owned and/or commercial forests. The nature of scientific uncertainty about diseases does not affect peoples’ preferences for disease control measures significantly. Higher respondent income, greater ex‐ante knowledge about tree diseases, and more frequent visits to forests are correlated with greater willingness to support publicly‐funded tree disease control programmes in forests. Better knowledge about tree diseases also improves the clarity of respondents’ choices. We find a negative sentiment against some disease control measures, such as clear felling of a forest, and chemical or biocide spraying. We conclude that there is significant public support for part‐financing forest disease control policies in the UK, but that this is conditional on forest ownership and the type of control measures used.  相似文献

Soil erosion produces both on‐site private costs and off‐site social costs, such as desertification, rural depopulation, siltation of waterways and reductions in biodiversity. To design efficient policies, land use planners and decision makers need information on the relative weights of changes in these consequences, since policy alternatives, such as different management restrictions, will have varying impacts on these consequences of erosion. The research presented here uses the choice experiment method to evaluate these relative weights, using a case study in the Alto Genil and Guadajoz watersheds in southern Spain. We find that reductions in desertification, protection of water quality, protection of biodiversity, the area covered by the scheme, and the number of rural jobs safeguarded are all significant determinants of preferences over alternative policy designs.  相似文献
