Accounting for Negative,Zero and Positive Willingness to Pay for Landscape Change in a National Park
Nick Hanley Sergio Colombo Bengt Kriström Fiona Watson 《Journal of Agricultural Economics》2009,60(1):1-16
In contingent valuation, despite the fact that many externalities manifest themselves as costs to some and benefits to others, most studies restrict willingness to pay to being non‐negative. In this paper, we investigate the impact of allowing for negative, zero and positive preferences for prospective changes in woodland cover in two UK national parks, the Lake District and the Trossachs. An extended spike model is used to accomplish this. The policy implications of not allowing for negative values in terms of aggregate benefits are also investigated, by comparing the extended spike model with a simple spike making use of only zero and positive bids, and a model which considers positive bids only. We find that ignoring negative values over‐states the aggregate benefits of a woodland planting project by up to 44%. 相似文献

Occupational diversification among household members in rural India is investigated as an adaptation strategy against the risks arising from the variability of local rainfall. Nationally representative household‐level survey data are combined with the coefficient of variation of rainfall constructed based on historical rainfall data at the district level. The analysis finds that high rainfall variability has significant negative effects on the agricultural specialization of within‐household occupational choices. This result is reinforced by the finding that improved access to irrigation, education, credit, roads, and postal services, is associated with a lower occupational diversification within families and a greater specialization of household members in agricultural‐related employment. 相似文献

The present study analyses research conducted in Service Dominant Logic (S-D logic), providing an overview of its intellectual structure. For that purpose, a structured approach was adopted through the implementation of bibliometric methods, using co-citation analysis combined with performance analysis and an integrative science mapping approach, which considered a timeline, a graph, and a distance-based perspective. This allowed the identification of the leading authors and of six clusters of articles based on bibliographic coupling, along with the most prominent research themes clustered in five subdomains of research based on co-occurrence of terms. The networks extracted show the associations between the main articles and concepts treated by the S-D logic community, unveiling the salient challenges and prospective expansion facing its future theoretical and practical context. 相似文献

This study empirically analyses the effect that the bankruptcy law has on firms’ performance based on its financial situation. To do this, we considered the different types of efficiency and their influence on firms’ value. The study was carried out for Germany, Spain, the United States, France and the United Kingdom. We applied System‐GMM estimation to dynamic panel data. The main results show that under creditor‐oriented systems, there is a decrease in the value of both financially distressed firms and those filing for bankruptcy. 相似文献

Like manufacturing multinational enterprises, multinational banks, although being more subject to local regulation and market preferences, are increasingly changing their international attitude. Namely, they rely on foreign activities not only as a means to exploit their own competitive advantages within foreign markets, but also to access exclusive assets, resources, and competencies that could be transferred back to the whole network to enhance and strengthen their competitive advantages. The reported research refers to data on the evolution of the Italian banks' foreign initiatives in the 1998–2004 period. Using such data, the authors investigate the determinants of the coexistence of strategies that are both competence-exploiting and competence-enhancing, using the traditional eclectic approach. 相似文献

Learner-centred approaches follow the prevailing tendency in modern University reforms which are primarily concerned about
“how people learn”. The methodologies can be learner-centred in the sense of placing the student as the main actor of the
teaching–learning process by increasing his interactivity and participation, but also considering what is relevant for the
student by measuring the learner satisfaction. In order to promote both aspects, this paper proposes a synchronous software-based
active methodology that makes use of the simulations to show a virtual scenario to the students and challenge them to predict
and discuss the evolution of the scenario. The proposed methodology improves the visual interface, promotes discussion both
among students and with the teacher in a brainstorming stage and shows real-world examples. This software-based methodology
has been implemented into an Electric Machinery course at the University of Seville (Spain), and the evaluation has been carried
out considering both the affective and cognitive domains. Principal components analysis proves to be useful to highlight the
dimensions with a higher influence on learner satisfaction and the affective and cognitive results confirm the successful
implementation of the proposal. 相似文献

abstract Previous research has portrayed buyer–supplier and supplier–supplier alliances as important mechanisms to foster learning and exchange efficiencies. Controversy remains, however, as to how these alliances interact. While some propose they reinforce one another (e.g. learning in horizontal ties generates positive spillovers to vertical ties), others propose a negative interplay (e.g. when increasing vertical-tie intensity, suppliers may weaken horizontal ties to avoid retaliation from buyers who wish to preserve bargaining power). We empirically test these competing views using survey data from the Brazilian auto-parts industry. In an attempt at reconciliation, we propose that the positive or negative interaction between vertical and horizontal alliances depends on the level of technological uncertainty of goods exchanged. Vertical ties seem to inhibit horizontal ties when technological uncertainty is low; when technological uncertainty is higher, vertical and horizontal ties do not seem to have any meaningful form of interaction. We discuss implications for theory and practice. 相似文献

This paper proposes a stylized two‐period, two‐country model illustrating the role of distribution of domestic wealth in determining a country's level of access to international lending. We model sovereign debt redemption policy in a common agency framework. Within this framework, policy is the outcome of the interaction between government and local and foreign interest groups with conflicting preferences on debt repayment. Our main result is that in full lobby competition, when all interests are represented, the only equilibrium solution is repudiation and the consequent inability of government to access international capital markets. Conversely, when the ability to lobby depends on wealth, governments can access international credit up to a given maximum external debt capacity, determined by the skew in the distribution of domestic wealth. 相似文献

It is often assumed that the fight against inequality played an important role in the rise of the welfare state. However, using social transfers as an indicator of redistribution and three alternative proxies for inequality—the top income shares, the ratio of the GDP per capita to the unskilled wage, and the share of non‐family farms—this article shows that inequality did not favour the development of social policy between 1880 and 1930. On the contrary, social policy developed more easily in countries that were previously more egalitarian, suggesting that unequal societies were in a sort of inequality trap, where inequality itself was an obstacle to redistribution. 相似文献
