Assign an economic value to environmental resources is not yet a widespread practice. The environmental management has been focused mainly on assessment of the impacts generated by the unbalanced exploitation of these resources. Therefore, this work has as overall goal performing economic valuation of Dunes State Park of Natal in Natal/RN, analyzing the Willingness to Pay (WTP) for students and employees of the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) through Contingent Valuation Method (CVM), considering its natural attractions, and specific objectives, we analyze the socioeconomic profile of students and employees and their concerns about environmental issues, as well we estimate the function WTP for the use of environmental attractions of the park. Finally, we relate the value of the WTP Park socioeconomic characteristics of the students and IFRN servers. As methodology, we used a bibliographic review of the existing literature and a field research, executed at Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN), Natal-campus center, where we applied a questionnaire in the open form of elicitation, during September of 2012, among students aged 18 years and servers (administrative staff and teachers) of this educational institution, gathering also socioeconomic information of the individuals. The results demonstrated that through the regression model, analyzed in general, we have evidence for a significance level of 6,8% there is a significant difference between the amount willing to pay for the maintenance of the park with family income and net income, in other words, as the individual has a higher net income and family, value willing to pay for the maintenance of the Dunes state Park tends to be higher. Furthermore, it was detected that there is also significant effect with respect to schooling, where as you increase the educational level of the individual, the average willing to pay for the maintenance of the Dunes state Park also increases. A fact relevant as adjustments in the general model, it is found not to have significant effect on the amount willing to pay for the maintenance of the Dunes state Park with respect to students and servers. / A valoração econômica de ativos ambientais tem ganhado relevância como instrumentos para auxiliar a tomada de decisão tanto de gestores públicos e legisladores, como de investidores e empresários. Atribuir um valor econômico aos recursos ambientais não é, ainda, uma prática difundida. A gestão ambiental tem se preocupado principalmente na avaliação dos impactos gerados pela exploração desequilibrada desses recursos. Logo, este trabalho tem como objetivo geral realizar a valoração econômica do Parque Estadual Dunas de Natal, em Natal/RN, analisando a Disposição a Pagar (DAP) de alunos e servidores do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) por meio do Método de Valoração Contingente (MVC), considerando seus atrativos naturais; e como objetivos específicos, analisamos o perfil socioeconômico de alunos e servidores e de seus interesses sobre as questões ambientais, bem como estimamos a função DAP pelo uso dos atrativos ambientais do parque. E, por fim, relacionamos o valor da DAP do parque às características socioeconômicos dos discentes e servidores do IFRN. Como metodologia, utilizamos uma revisão bibliográfica da literatura existente e uma pesquisa de campo, realizada no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN), Câmpus Natal-Central, onde aplicamos um questionário na forma aberta de eliciação, durante o mês de setembro de 2012, entre os alunos maiores de 18 anos e servidores (técnicos administrativos e professores) desta instituição de ensino, reunindo também informações socioeconômicas dos indivíduos amostrados. Os resultados demonstraram que, através do modelo de regressão, analisado de forma geral, temos evidências para um nível de significância de 6,8% que existe diferença significativa entre o valor disposto a pagar pela manutenção do parque com renda familiar e renda líquida, ou seja, a medida que o indivíduo possui maior renda líquida e familiar, o valor disposto a pagar pela manutenção do Parque das Dunas tende a ser maior. Além disso, foi detectado que existe efeito significativo também com relação ao grau de escolaridade, onde a medida que aumenta o grau de escolaridade do indívíduo, o valor médio disposto a pagar pela manutenção do Parque das Dunas também aumenta. Um fato relevante visto nos ajustes do modelo geral, trata-se de não ter encontrado efeito significativo no valor disposto a pagar pela manutenção do Parque das Dunas com relação aos estudantes e servidores.

This thesis deals with a relatively new issue in the Czech Republic, which is valuing cultural organizations. The general framework for the valuation of non-profit cultural organization is analysed in the theoretical part. It includes a discussion of the importance of culture for society, the characteristics of non-profit organizations and subsequently defining the potential value of the concept of cultural organizations, reasons and methods for valuation of such organizations. Special focus is paid to the transformation of the Prague theater net. The aim of the practical part is to determine the approximate value which the czech society would lose, if the prague theatre Činoherní klub terminates its activities due to financial reasons. Contingent valuation method is applied as a procedure, which is based on detection of individual willingness to pay (WTP) or willingness to accept compensation (WTA), through a questionnaire survey. There is also a determination of the status of the valued theater at the Prague theater market in the practical part.

Le financement des soins de santé de qualité constitue un défi majeur pour les pays en développement. Malgré les efforts consentis pour améliorer l’offre des services de santé, une frange importante de la population n’a toujours pas accès aux soins de santé. La faible croissance économique, le manque des ressources, la corruption et les contraintes imposées au secteur public peuvent expliquer pourquoi la conception d’un système de financement des soins de santé est complexe. Au cours des deux dernières décennies, il y a eu une baisse de l'utilisation des services de santé après l'introduction du recouvrement des coûts dans les établissements de santé publics. Les personnes les plus touchées par cette politique sont les ménages à faibles revenus notamment dans les zones rurales qui sont le plus souvent vulnérables aux maladies. L'assurance communautaire a été proposée comme une alternative pour améliorer une meilleure accessibilité des ménages à faibles revenus aux soins de santé. L'assurance communautaire apparaît ainsi comme un outil de protection sociale pour un grand nombre de personnes qui, autrement, n'auraient pas une couverture face au risque maladie. Toutefois, un tel système d’assurance maladie ne peut avoir des effets à long terme que s’il existe une forte préférence des ménages pour une telle politique, et un capital social dans les zones rurales. Evaluer les préférences des ménages pour l'assurance communautaire est importante pour la formulation des recommandations de politique économique. Une connaissance adéquate des déterminants de la demande pour l'assurance communautaire est aussi essentielle pour l'élaboration de stratégies visant à accroître l’allocation des ressources, et à améliorer la qualité des services. La présente étude a pour objet d’évaluer les préférences des ménages pour l’assurance communautaire en milieu rural camerounais. L’usage de la méthode d’évaluation contingente suggère que les ménages à faibles revenus sont disposés à payer pour l’assurance communautaire. En outre, le capital social a un effet positif et significatif sur la demande. L’usage des doubles questions binaires pour évaluer des préférences des ménages est incompatible avec les incitations et sujets à un shift effect hétérogène expliqué par les caractéristiques intrinsèques des ménages. Les ménages très certains de leurs réponses ne sont pas sujets aux anomalies comportementales. Enfin, les préférences des ménages sont inter-indépendantes du fait des interactions spatiales expliquées par les normes sociales / The financing of quality healthcare is a major challenge for developing countries. Despite efforts to improve the provision of healthcare services, a significant proportion of the population does not always have access to healthcare services. Low economic growth, lack of economic resources, corruption and constraints on the public sector could explain why the design of a system of financing healthcare is complex. Over the past two decades, there has been a decline in the use of healthcare services after the introduction of cost recovery in public health facilities. Those most affected by this policy are low-income households particularly in rural areas that are most often vulnerable to diseases. The community-based health insurance has been proposed as an alternative to improve better access to low-income households to healthcare services. The community-based health insurance is thus a tool of social protection for many households who otherwise would not have formal insurance. However, such a health insurance scheme can have long-term effects if households have a strong preference for it, and there is social capital in rural areas. Assessing the preferences of households for the community-based health insurance is important for the formulation of policy recommendations. Adequate knowledge on the determinants of demand for the community-based health insurance is essential for developing strategies to increase resource allocation, and improve the quality of services. This study aims at assessing the preferences of households for community-based health insurance in rural areas of Cameroon. The use of contingent valuation method suggests that low-income households are willing to pay for the community-based health insurance. Furthermore, social capital has a positive and significant effect on the demand, and the use of double-bounded dichotomous choice to assess the preferences of households is incentive incompatible. We also found that there is heterogeneous shift effect in preferences anomalies and could be mostly explained by the salient characteristics of households. A striking result is that more certain households are not subjected to preference anomalies. Lastly, there is spatial dependence in the preferences of households explained by social norms

The main purpose of the diploma thesis is to determine the willingness of people visiting the Eastern Slovak dam Ružín to pay for improving water quality, namely for the environmental good. Willingness to pay is determined by questionnaire investigation the contingent valuation method. Dam is a public good, which has no owner. We all use it without someone to care for it. This use is not positive, but negative in terms of pollution, clogging of toxic sediments. The theoretical part is devoted to construction and the need to build dam as well as environmental problems, which occur at the dam. This is related to the problem of public good and "the tragedy of the commons." There are the contingent valuation method and development of the questionnaire described at the end of theoretical part. The practical part consists of the evaluation questionnaire investigation and the linear regression model in terms of the parameters under which they were created identifiers variables and point estimates. Finally, it is converted by statistical analysis of the impact of variables on the amount that people are willing to pay.

No. of bitstreams: 1 CLEUTON CLENES DA SILVA.pdf: 1417621 bytes, checksum: 3f9b7f8cea0cb7097d1e697b0a56809b (MD5) Previous issue date: 2012-12-20 / This study evaluates the spontaneous Willingness to Pay (WTP) of a proportion of the Goiania II and Sao Judas Tadeu Goiânia residents in order to reduce or eliminate the air pollution, supposedly generated by Goiania II ETE (Sewage Treatment System) and Unilever, which could result in improved quality of life for those who live nearby. The goal of the research was to put a price on environmental pollution, so it was decided to use the Contingent Valuation Method (CVM), as this is most frequently recommended and used when analyzing individual consumer preference in relation to the environmental goods or services at their disposal. As a field research technique, questionnaires were given to a sample of this population, with the aim of evaluating the interviewees conceptions in relation to the environmental issues exacerbated by the Goiania II ETE and Unilever. In order to justify and tabulate the answers found in the questionnaires, the SPSS statistical program was used for regression analyses. Spontaneous WTP was considered the dependent variable while the independent variables included income, education level, occupation, etc.. By means of the field research, it could be affirmed from the majority of interviewees responses that the problem of air pollution, from their conception, is associated in particular with the industries of the region. They further highlight that Government at all levels (local, state and federal) is negligent in terms of the environmental issues which affect the residents. It was concluded that the vast majority of respondents is not willing to pay to reduce or eliminate the existing air pollution that they have to put up with, allegedly for economic reasons. Respondents warn that the Goiania II ETE and Unilever need to improve collective sewage treatment and put environmental policies in place. / Esta pesquisa avalia a Disposição a Pagar (DAP) espontânea de um percentual dos habitantes dos setores Goiânia II e São Judas Tadeu de Goiânia, para diminuir ou desaparecer com o problema da poluição do ar gerado supostamente pela ETE Goiânia II e Unilever, o que poderá resultar na melhoria da qualidade de vida dos habitantes que vivem nas proximidades dessas empresas. O objetivo da pesquisa é, valorar a poluição ambiental, por isso, decidiu-se pelo Método de Valoração Contingente (MVC), devido ser o mais recomendado e utilizado para analisar a preferência individual dos consumidores em relação aos bens ou serviços ambientais disponibilizados a eles. A técnica utilizada na pesquisa de campo foi o uso de questionários a uma amostra dessa população, tendo como intuito, avaliar a concepção dos entrevistados em relação à questão ambiental agravada pela ETE Goiânia II e Unilever. Para justificar e tabular as respostas encontradas nos questionários foi utilizado o programa estatístico SPSS fazendo a análise de regressão. Considerou-se como variável dependente a Disposição a Pagar (DAP), e como variáveis independentes, a renda, o nível de escolaridade, profissão, etc. Pela pesquisa de campo, pôde-se afirmar através da maioria dos pesquisados, que o problema do ar poluído, nas suas concepções, está associado em especial às indústrias da região. Destacam ainda que, o Poder Público em todas as esferas (municipal, estadual e federal), são omissos no que diz respeito aos problemas ambientais que os afetam. Conclui-se ainda que, a grande maioria dos pesquisados, não estão dispostos a pagar uma taxa para diminuir ou desaparecer com a poluição do ar existente e que os atingem, alegando sobretudo, fatores econômicos. Os pesquisados alertam que, a ETE Goiânia II e a Unilever precisam fazer um tratamento melhor do esgoto coletivo e apliquem em políticas ambientais.

The goal of the work is to provide monetary valuation of changes in visual aspects of the landscape as a result of construction of an additional wind turbine in the village Maletín. For a suitable method for achieving the goal is being selected the contingent valuation method. A key element of this method is being considered the carefully compiled questionnaire, on which basis is made the quantification and evaluation of collected data. The representative sample consists of 112 households and the selected payment method is the increase of the monthly bill for electricity. The questionnaire reports that 54.3% of households consider the impact of wind turbines on the landscape Maletín to be positive. With the construction of additional wind turbine agree less than 74.3% of households and the most common reason is to obtain grants for the village and to produce cleaner energy from wind turbines. With the construction of new wind turbine while increasing monthly bill agrees 28.6% of all households living in the village Maletín. Estimation of changes in a welfare, thus improving the quality of the environment, is based on estimated central values, that has been calculated from selected characteristics and nonparametric estimation. The average household's willingness to pay for construction of wind turbine is estimated to be between 77 CZK - 200 CZK per month.

假設市場評價法（Contingent valuation）多用於評估有關某一非市場性財產（Non-market goods）或公共財（Public goods）在民眾心目中的願付價值（Willingness to pay, WTP）。探討受訪者願付價值之研究調查案的問卷設計方式，大致可分成五種，其中開放式出價法和逐步競價法已被證實會對估計造成偏誤，而支付卡法、二分選擇法和雙界二分選擇法則是現今較常為研究者所使用的價格詢問方法，本論文的研究是針對二分選擇法的最佳設計（Optimal design），作一深入的探討。 假設欲探究之母體的願付價值為一服從平均數為 、標準差為 的常態分配，若採用二分選擇法作為價格詢問的方式，則何種詢問方法才能讓參數估計最佳化，由模擬實驗的結果，我們知道若將受訪者隨機等分成兩群，分別詢問兩個不同的價格，且這兩個價格的平均等於預先猜測的母體平均數，那麼不但會有相當不錯的估計結果，在實際的執行上亦較方便。此外，我們提出較容易計算的參數估計量來代替傳統的最大概似估計量（MLE），並以數理證明保證了新的參數估計量有良好的估計性質。 願付價值的研究若對母體資訊不充分時，常會先採行前測（Pretest）。本論文除了探討二分選擇法的最佳設計之外，亦針對支付卡法和二分選擇法運用在前測時，作一深入的討論，結果發現當事先猜測的母體分配參數和真實分配相差很多下，支付卡法和二分選擇法會產生無法估計的情況，因此我們提出新的前測方法，試圖彌補這兩種傳統前測法的不足，我們稱之為序列詢問法（Sequence method）。序列詢問法為一種追蹤母體平均數的方式，依照現在這位受訪者的回答，決定下一位受訪者的詢問價格，在我們的研究中發現，如此的序列詢問方法比傳統的前測法利用更少的資訊，但仍然維持不錯的母體平均數估計結果。
