臺灣西南沿海地區由於超抽地下水，地層下陷情形日益嚴重，究其原因乃地下水資源在國內仍處於「自由財」的狀態，用水兔費，使用自然缺乏效率，因而建立使用者付費制度，以確實維護地下水財產權，為當務之急。惟地下水資源具公共財的無排他性，在國內又無交易市場，其價值估算困難。是故，本文之主要目的，係應用非市場估價法中之「條件評價法」，以願付價格的形式估計地下水價值，並探求其影響因素，以做為制定政策之參考。 本文係以「準逐步競價法」為詢價結構設計，可同時獲得「單邊界樣本」、「雙邊界樣本」與「最終出價樣本」三種評價歷程，實證模型則分別以「Probit、Logit模型」、「存活模型」與「OLS模型」進行分析。 本文根據問卷調查的原始資料求出「每公頃土地」之地下水願付價格，最後則以台西地區為例，配合地下水的使用效益，計算出地下水供不同使用時之「使用價值」與「非使用價值」，而本研究對假設性問題的設計，使估計出來的地下水價值，亦可用以表示維護地下水資源對於防止地層下陷之效益。 實證結果顯示，「對水權費的認知與態度」以及「對地層下陷原因的認知」是影響支付意願的重要因素，故政府應加強宣導「使用者付費」理念，並教育用水者「超抽地下水是造成地層下陷的重要因素」，以利水權費制度的實施。

The aims of this thesis were to evaluate caries-preventive measures from a societal perspective, to demonstrate the use of resources in preventive dentistry, to develop and discuss techniques suitable for evaluating dental care costs and outcomes, and to test costs and consequences within a health economic decision model adapted to preventive dental care. The thesis is based on three separate studies with three separate cohorts. In the first study, performed at a single dental clinic, analysis was made of data on dental caries progression over four years in 92 adolescents, along with the use of resources for preventive treatment. In the second study, data from the intervention study “Evaluation of caries-preventive measures” (performed between 1995 and 1999 at 26 dental health clinics throughout Sweden) were used for economic evaluation. Three different approaches to calculating unit cost were discussed, each of which reflect the differences in treatment costs as influenced by the practitioner’s level of skill and competence (salary) and by methods of handling overhead cost allocation. These methods seem useful for evaluating costs in cost-effectiveness analysis (CEA) and cost-benefit analysis (CBA). The CEA showed an incremental cost-effectiveness over four years of SEK 2 043* per averted decayed (D) enamel (e) and dentine caries, missing (M) and filled (F) surface (S) (DeMFS). In the third study, 82 19-year-old individuals agreed to participate in a pilot exploratory case-control study. Individuals with high caries experience formed the test group while the control group consisted of individuals with no caries experience. To explore whether any differences existed between these two groups in perceived oral health-related quality of life (OHRQOL), two OHRQOL measures were used. Additionally, the willingness of these individuals to pay (WTP) for a preventive strategy was elicited using the contingent valuation method (CVM) within a cost-benefit approach. Using these WTP values, the cost-benefit analyses showed positive net social benefit (NSB) values for both study groups, meaning that the benefits of prevention exceeded the costs. A new outcome measure, Value of Statistical Oral Health (VOSOH), was also presented. Consideration was also made, within the economic framework fundamental to this thesis, of the trend away from a strictly bio-medical paradigm towards a biopsychosocial perspective. The health economic decision model encompasses a number of different techniques for comparing costs with consequences, each with its own advantages and disadvantages and each with its own field of application. These techniques should be seen as complementary rather than competing. Preventive dentistry plays a central role in Swedish dental health care, and it is important that resources are used properly. Accurate evaluation methods are necessary in order to improve the basis for public decision-making; the methods proposed in this thesis seem to be of potential use in this endeavour. *SEK8.54 = US$1 (December 1999).

O m?todo de Valora??o Contingente ? capaz de estimar o valor de n?o-uso de um recurso natural atrav?s da utiliza??o de um mercado hipot?tico que consiste em um cen?rio ambiental fict?cio em que o bem ambiental sofre varia??es em suas quantidades e os indiv?duos expressam suas prefer?ncias declarando quanto estariam dispostos a pagar (ou aceitar) para garantir a continuidade (ou a perda) da provis?o do bem. Neste estudo, foram aplicadas duas formas de pagamento para o mercado hipot?tico da t?cnica de Disposi??o a Pagar (coletiva/obrigat?ria e individual/volunt?ria) com o objetivo de identificar a demanda da popula??o por investimentos p?blicos nas unidades de conserva??o costeiras urbanas, para testar a efici?ncia de ambas formas de pagamento e para captar os votos de protesto dos entrevistados, na tentativa incorporar nas an?lises a verdadeira disposi??o a pagar dos entrevistados pela a manuten??o e conserva??o das unidades de conserva??o. Os resultados mostraram maiores lances de disposi??o a pagar para a forma de pagamento coletiva e obrigat?ria, pois em pa?ses em desenvolvimento as pessoas atribuem ao governo o financiamento da conserva??o de paisagens naturais. A diferen?a entre os valores de n?o-uso estimados pelas duas formas de pagamento foi de R$8,2 milh?es (3.5 milh?es) e isso representa a demanda da popula??o local por investimentos p?blicos na conserva??o das ?reas costeiras. O M?todo do Custo de Viagem foi utilizado para estimar o valor de uso das dunas, obtido a partir dos gastos incorridos pelos visitantes ao visitar as ?reas de dunas e o somat?rio deste valor ao valor de n?o-uso representa o valor econ?mico total agregado pela paisagem de parques dunares. Paisagens dunares geram anualmente um montante de R$ 800.428,46 por hectare (US$ 339,049.67). A maior contribui??o para esse montante econ?mico ? do parque visitado por turistas, em que o valor agregado pela recrea??o ? 53 vezes maior que o parque visitado por moradores. Embora turistas e moradores reconhe?am os benef?cios de alguns servi?os proporcionados por este ecossistema, ambos atribuem maior valor ? contempla??o da paisagem natural e ? recrea??o ao ar livre. A estimativa desse valor para os diferentes tipos de p?blico oferece ? gestores um justificativa econ?mica para direcionar uso e conserva??o de ?reas de dunas, subsidia na tomada de decis?o atrav?s de an?lises de custo benef?cio no processo de formula??o, acompanhamento e avalia??o de pol?ticas p?blicas e auxilia a investigar como os benef?cios variam de acordo com os tipos de visitantes. Portanto, o uso de estimativas do valor do meio ambiente nesta disserta??o, identificou o valor econ?mico intr?nseco das ?reas de dunas ?s ?reas naturais e o valor agregado pela sua exist?ncia e, portanto, permite que se dimensione a import?ncia dos investimentos em sua conserva??o e restaura??o, podendo ser utilizada como indicador para direcionar pol?ticas e distribui??o de investimentos para a conserva??o dos mesmos. Outro aspecto importante na aplicabilidade de metodologias de valora??o ambiental ? a contribui??o que o uso desse instrumento traz para o debate cient?fico sobre os problemas t?cnicos existentes nas metodologias

The rural homegardens are important production systems to complement other forms of land use, which besides providing food security for farmers, they perform functions aesthetic, recreational and conservation of local biodiversity. Thus, the study aimed to examine the total economic value (TEV) of the backyards of the universe of rural farmers involved in the Cooperative Family Farming of Itapuranga, noting its main economic functions, environmental and cultural. By means of the contingent valuation method, using the technique "payment card", tried to capture also the values of these non-market yards, as the perception and preferences of the farmers interviewed. Thus, 40 questionnaires were applied and visited 35 farms, where it was possible to observe directly the interaction of families with that environment. For economic functions, there was a survey of the main items (gross) consumed and sold during October 2007 and October 2008, reaching an average value of direct use of R$ 420.70 monthly. Other benefits from the yards were measured by DAP of the farmers interviewed, obtained by the MAC, with an average value of R $ 493.75 monthly. These values also correspond to the sociocultural aspects related to the tradition of those families where the woman responds by management and by the choices of crops, according to the tastes and habits of the family group. Regarding environmental aspects, the yards are considered important agroecological systems, since in most cases are not used chemical or toxic substances in their production. In recent years, faced with environmental problems in general, and the reopening of the sugarcane agro-industry in the city of Itapuranga, so does the importance of gardens as conservative biodiversity and balance of the fauna and flora. / A valorização da agricultura familiar pela sociedade brasileira constitui-se uma importante ferramenta de desenvolvimento local, uma vez que esta utiliza os recursos escassos, como a terra e a mão-de-obra, de forma eficiente. Os quintais rurais são importantes sistemas de produção complementar às outras formas de utilização da terra, que além de possibilitar a segurança alimentar dos agricultores familiares, desempenham funções estéticas, de lazer e de preservação da biodiversidade local. Dessa forma, o trabalho buscou analisar o valor econômico total (VET) dos quintais rurais do universo dos agricultores familiares associados à Cooperativa de Agricultura Familiar de Itapuranga, observando as suas principais funções econômicas, ambientais e culturais. Por meio do Método de Avaliação Contingente, utilizando a técnica cartão de pagamento , procurou-se captar também os valores de extramercado desses quintais, conforme a percepção e as preferências dos agricultores entrevistados. Com isso, foram aplicados 40 questionários e visitadas 35 propriedades rurais, onde foi possível observar diretamente a interação das famílias com esse ambiente. Para as funções econômicas, fez-se o levantamento dos principais itens (brutos) consumidos e vendidos durante outubro de 2007 e setembro de 2008, chegando-se a um valor médio de uso direto de R$ 420,70 mensais. Os demais benefícios provenientes dos quintais foram mensurados pela DAP dos agricultores entrevistados, obtida através do MAC, apresentando um valor médio de R$ 493,75 mensais. Esses valores correspondem também aos aspectos socioculturais ligados à tradição dessas famílias, onde a mulher responde pelo manejo e pelas escolhas dos cultivos, conforme os gostos e costumes do grupo familiar. Quanto aos aspectos ambientais, os quintais são considerados importantes sistemas agroecológicos, já que na maior parte das vezes não são utilizadas substâncias tóxicas ou químicas em sua produção. Nos últimos anos, frente à problemática ambiental de uma forma geral e com a reabertura da agroindústria canavieira no município de Itapuranga, cresce também a importância dos quintais enquanto conservador da biodiversidade e do equilíbrio da fauna e da flora local.

This master's thesis focuses on the valuation of the Municipal Library in Prague, the cultural institution allowances organization. Its aim is to estimate the value up for the date of 31th October 2013 for the purpose of its founder, Prague - the capital city, and to compare the measured value with the level of annual non-capital contribution for the Municipal Library from its founder. The valuation was performed by using the contingent valuation method, which is based on random sample of the questionnaire survey respondents who express their preferences. They are gradually guided to be able to provide the maximum price that they would be willing to pay for use of services and to be able to work out what financial compensation they would be willing to accept for the decrease in their quality life. The starting point of this thesis is to determine the prognosis of the number of registered readers, borrowings, economy of the Municipal Library, its market position and other requisites. This thesis is one of the few which contains valuation in the cultural sector in the Czech Republic.

The diploma thesis deals with validity of direct measurement of stated willingness to pay (WTP) in the fair trade context based on two-phase measurement applied in the INESAN survey. Attention is also paid to the unit of answer to an open-ended question and to the functionality of WTP as an indicator of purchase intent. First, fair trade, the concept of WTP with focus on areas of its application, ways of measurement, critics and problems of its use are introduced from the theoretical perspective. Further, cognitive aspects of the process of answering survey questions as a way of testing the functionality of a measurement tool are analyzed. The thesis is built on a combination of two survey methods, cognitive interviews and secondary analysis of quantitative data. It concludes that measuring WTP for the purpose of capturing the value of fair trade using direct stated method of measurement is problematic as numerous risks with impact on validity of acquired data appear. Those risks concern both the particular way of measurement and the direct stated WTP measurement in general, starting with ambiguous interpretation of WTP questions for a fair trade product among respondents. The thesis also shows that answering open-ended question in the form of percentage is cognitively more demanding than in the...

This dissertation focuses on the non-market valuation of health-risks of malaria, an infectious disease that imposes a substantive public health burden across the globe, hitting particularly hard the tropical developing nations of Africa and Asia. The United Nations Millennium Development Goals include malaria control as a priority and large investments are underway to promote effective prevention and treatment. Despite such concerted supply-side efforts, malaria-related mortality and morbidity still abound due to a complex interface of factors like climate-change, poverty, inadequate control behavior, infection and prevention externalities, parasite resistance etc. This research project digs into the demand-side of the health problem, considers the "externality" dimension to prevention, and primarily asks the question: how do individuals in developing countries view competing disease-control (prevention) measures, viz. a publicly-administered community-level malaria control measure as against private preventive choices. A theoretical model is developed to help explore the public-private interplay of health risks of malaria. The malaria-endemic regions of Kolkata (India) and its rural fringes comprise the site for an empirical investigation. A field survey (Malaria Risk and Prevention Survey, October-December, 2011) incorporating a mix of stated and revealed preference techniques of health valuation is implemented. Risk-perceptions of respondents are elicited using a measurable visual-aid and individuals' perceived valuations of health-risk reductions, randomly offered with the public and private health treatments, are empirically ascertained. Using a Likelihood Ratio Test on the structural risk parameters, it is seen that individuals’ valuations of health risk reductions are the same across the private and public treatments. The comparative valuation iv exercise, thus, corroborates the externality dimension to malaria control, calling for greater public action to combat malaria. The viability of such a scaled-up public malaria program, in the context of Kolkata, is discussed by comparing the public treatment willingness to pay estimates with the annual estimated costs that the Kolkata Municipal Corporation, the civic body in the city of Kolkata, maintains on account of vector control. Results from the comparative valuation exercises also support the idea that private prevention is generally responsive to prevention costs, indicating the importance of price incentives to induce greater prevention. The issues of health valuation and price sensitivity are further explored across various split-samples differentiated on the basis of socio-economic attributes, disease exposure, actual prevention efforts and perceived malaria risks of survey respondents. Such auxiliary exercises help analyze the valuation question in greater depth, and generate policy insights into the potential factors that shape private prevention behavior.

由於社會變遷迅速，文化資產保存工作，無論在有形或無形資產方面均面臨了嚴苛的挑戰。許多為保存歷史建物、遺址、文物或技藝之民間組織或政府文化機構無不極力爭取以獲得必要的經費資源，以防止文化資產的快速流逝。近年來政府對文化資源的投入程度受到廣泛關注，在財政緊縮下，政府削減各項支出中有關文化設施之補助，或限縮地方政府的文化預算，引起各界對文化預算資源配置問題的熱烈討論，導致以經濟觀點衡量文化產出或文化設施之評價日顯重要。在俱歷史性之藝術或文化資源領域，由於其價值無法快速藉由市場價格機制訂出來，衡量文化政策之最適資源投資一直引起激烈爭議，在各部會資源競爭之下，為了獲得足夠的預算分配，政府各部門必須彰顯其對整體經濟效益之貢獻，因此近年來越來越多研究針對非市場財貨之公共投資進行經濟效益評估。調查民眾對文化公共財的願付價格，除可顯示民眾對文化公共財偏好強度以進行成本效益分析外，亦可作為該文化機構自行籌措財源擬訂定價策略之參考，並可提供政府當局財政配置及公共投資之依據，本篇研究將以非市場財貨評估中之條件評估法，以文建會所屬文化機構國立傳統藝術中心為例，求算民眾對該機構之願付價格。 / 實證結果，在估計參數值部份，發現文化資產保存重要性認同度、文化資產遺贈價值認同度、文化資產預算擴編認同度、年齡、文化產業消費頻率等變數，對受訪者的支付意願均有顯著影響；第一階段與第二階段的詢價金額係數估計值為負並且顯著，表示當詢價金額提升時，受訪者會傾向於不願意支付。在單界二元選擇問答下，Logit模型估算其值為181.56元，Probit模型估算其值為199.12元，在95％信心水準下區間估計值Logit模型其值為191.56元到171.56元之間，Probit模型其值為205.90元到192.34元之間；在雙界二元選擇問答下以Bivariabe Probit 估算結果得到第一次詢價的願付價格為145.69元，第二次詢價的願付價格為218.42 元，實證結果單界與雙界二元選擇模型願付價格差異不大。 / Nowadays, historic building, monument, and artifacts, facing difficult issue of damaging, are quickly dying away. Agencies and organizations whose mission is to protect and preserve historic and culturally important building, monument, and artifacts from the ravages of weather, pollution, development, and even use by the general public must compete urgently for needed resources. Government funding of the cultural arts has received considerable attention in recent years. Efforts to cut funding to the national endowment for the culture and declining budgets for public cultural organizations and art institution have raised questions about how much individuals value the culture and arts. Measuring the economic value of particular arts policies or public cultural organizations is difficult and important. The hard case for measuring economic value of cultural resources is that they are not captured readily by market prices. The appropriate resources to be allocated in public cultural or art institutions often get heated and considerable debate. Valuing the willingness to pay for cultural public goods, not only can be applied for measuring economic value to be used in benefit-cost analysis of public project, but also more efficient in the selection of investment program if the total value（use value and non-use value）can be estimated. The purpose of this study is using one of the non-market goods valuation method, contingent valuation method, to elicit a willingness to pay from individual for hypothetical changes in some situation, further more to value the use value and non-use value of the“National Center for Traditional Art ”. / The variables such as the IMPO,BEQU, BUDG, AGE, FRE1, have a significant positive effect on the WTP for a cultural public good valuing. The table broadly indicates that as the bid level is increased, the number of willing to pay the amount decreased. The empirical results show that under the single-bounded dichotomous choice model, the estimated WTP for Logit model is NT$181.56 and for Probit model is NT$199.12. Under the 95％ confidence, for Logit mode the estimated WTP is between NT $191.56 and NT $171.56, and for Probit model is between NT $205.90 and NT $192.34. Under the double-bounded dichotomous choice model, Bivariate Probit model was adopted to estimate the WTP. The first-estimated WTP is NT $145.69, and second-estimated WTP is NT $218.42. The estimated WTP under double bounded dichotomous choice model is not much different from the estimated WTP under single bounded dichotomous choice model.

Les services écosystémiques (SE) réfèrent aux bénéfices que produisent et soutiennent la biodiversité et les écosystèmes et qui profitent à l’être humain. Dans beaucoup de cas, ils ne sont pas pris en compte dans le système économique. Cette externalisation des SE engendre des décisions sur l’utilisation du territoire et des ressources naturelles qui ignorent leur contribution à la qualité de vie des communautés. Afin notamment de sensibiliser l’opinion publique à l’importance des SE et de mieux les intégrer dans les processus décisionnels, ont été développées des démarches d’évaluation économique des SE. Dans cette thèse, nous avons cherché à comprendre à la fois comment l’utilisation passée et actuelle des sols dans la région de Montréal affecte la valeur des SE et comment ces aménités naturelles sont perçues et valorisées par la population, dans une perspective d’aménagement futur du territoire. Pour ce faire, nous avons utilisé deux approches : l’analyse spatiale recourant aux systèmes d’information géographique et l’analyse des préférences exprimées par des techniques d’enquête. Pour l’analyse spatiale, nous avons combiné des analyses cartographiques à des valeurs monétaires associées aux SE publiées dans la littérature. Nous avons alors estimé la valeur des écosystèmes d’un territoire par le transfert de bénéfices, de prix de marchés directs et de coûts évités. Cette démarche nous a permis de comprendre la relation entre l’utilisation actuelle du territoire du Grand Montréal écologique et la valeur des services fournis par les écosystèmes, que nous avons estimée à 2,2 milliards de dollars par année. Elle nous a permis aussi de mesurer les effets sur la valeur des SE du changement d’utilisation des sols entre les années 1960 et 2010. Nous avons montré que malgré différentes politiques de contrôle et d’encadrement de l’étalement urbain au cours de cette période, les pertes économiques non marchandes liées aux SE s’élèvent à 236 millions de dollars par année. Pour l’analyse des préférences exprimées, nous avons utlilisé deux méthodes, l’évaluation contingente et le choix multi-attributs, avec l’objectif de mesurer le consentement à payer de répondants pour des variations dans l’aménagement du territoire. Nous avons montré d’une part que les répondants valorisent significativement l’incidence des pratiques agro-environnementales sur la qualité de l’environnement et des paysages en consentant à payer entre 159 et 333 dollars par ménage par année pour une amélioration de la diversité du paysage agricole. D’autre part, leur volonté à payer pour l’amélioration de l’état des milieux humides du Québec est estimée entre 389 et 455 dollars par ménage par année. L’utilisation conjointe des deux méthodes nous a permis d’en comparer les résultats. Nous avons en outre démontré que le choix du format de question de valorisation de l’évaluation contingente affecte la convergence des résultats. Enfin, nous avons proposé des pistes de recherches futures portant sur l’intégration des démarches d’analyse biophysique, économique et politique dans des outils de prise de décision mieux adaptés à la dynamique des écosystèmes, de la biodiversité et des communautés humaines. / Ecosystem services (ES) refer to benefits produced and sustained by biodiversity and ecosystems that benefit humans. In many cases, they are not considered in the economic system. This externalization of SE generates decisions on land use and natural resources that ignore their contribution to the well-being of communities. In order to raise awareness of the importance of ES and better integrate them into decision-making processes, economic approaches to value ES have been developed. In this thesis, we sought to understand both how the past and current land use in the Montreal area affects the value of ES and how these natural amenities are perceived and valued by the population in a future planning and management perspective. To accomplish this, we used two approaches: spatial analysis using geographic information systems and analysis of stated preferences by survey techniques. In the spatial analysis approach, we combined cartographic analyzes to monetary values associated to ES published in the literature. We then estimated the value of ecosystems using benefit transfer, direct market prices and avoided costs methods. This approach has allowed us to understand the relationship between the current land use in the Greater Montreal and the economic value of the services provided by ecosystems, which we estimated at 2.2 billion dollars per year. It also allowed us to estimate the effects of land use changes between 1960 and 2010 on the value of ES. We showed that despite different land use planning policies implemented to manage urban sprawl during this period, non-market economic losses related to ES have reached 236 million dollars per year. In the stated preferences approach, we used two methods, contingent valuation and choice experiment, with the aim of measuring the willingness to pay of respondents for proposed changes in their environment. In a first study, we showed that respondents significantly value the impact of agri-environmental practices on the quality of the environment and landscapes and are willing to pay between 159 and 333 dollars per household per year on improving the diversity of agricultural landscape. In a second study, their willingness to pay on improving the status of wetlands in Quebec is estimated at between 389 and 455 dollars per household per year. The combined use of the two methods allowed us to compare the results. We also demonstrated that the choice of valuation question format in contingent valuation affects the convergence of the results. Finally, we propose directions for future research related to the integration of ecological, economic and political analyzes of ES that would lead to better assessments of the dynamics of ecosystems, biodiversity and human communities.

Ziel dieser Arbeit ist die Ermittlung des ökonomischen Wertes einer Öffentlichen Bibliothek in einer deutschen Mittelstadt. Dabei werden die Wertschätzung beeinflussende Faktoren identifiziert und die Einschätzungen der Bevölkerung (Bibliotheksnutzer und Nicht-Nutzer) mit der der politischen und administrativen Vertreter kontrastiert. Im theoretischen Teil wird der Forschungsstand zur Wert- und Wirkungsmessung dargelegt und in den Kontext der wirkungsorientierten Verwaltungsführung gestellt. Außerdem wird das Konzept der Lebensstile erläutert. Im empirischen Hauptteil wird eine schriftliche Befragung zur ökonomischen Wertschätzung der Stadtbibliothek Melle ausgewertet. Zwei parallele Umfragen richteten sich zum einen an Einwohner der Stadt Melle und zum anderen an politische und administrative Vertreter. Neben der ökonomischen Wertzumessung, ausgedrückt als Zahlungsbereitschaft (Anwendung der Kontingenten Bewertungsmethode), stehen die Aspekte Lebensstil-Typen nach Gunnar Otte, Bibliotheksnutzung, sowie die Stellung im Familien-/Lebenszyklus als beeinflussende Faktoren im Mittelpunkt der Auswertung. Die geäußerten Zahlungsbereitschaften der Bevölkerung und der Politiker werden verglichen. Es wird eine Relation von Zahlungsbereitschaft zu „Ergebnis je Einwohner“ (finanzbuchhalterische Kennzahl) als Indikator für die Wertschätzung gebildet. / The aim of this study is to determine the economic value of a public library in a medium-sized town in Germany. The factors influencing the value must first be identified and the population’s (both library users and non-users) appreciation must be compared with those of their political and administrative representatives. In the theoretical section of this study the current state of research in value and impact assessment will be explained and presented within the context of impact-oriented administration (New Public Management). The concept of lifestyles will also be explained. The main, empirical section of the study concentrates on the assessment of a written questionnaire (mail survey) on the economic value of the Melle Public Library. Two parallel questionnaires were conducted; one for the population of the city of Melle and one for their political and administrative agents. In addition to the economic rating of the library, expressed as willingness-to-pay (under application of the contingent valuation method) at the core of the assessment, the analysis focuses on the aspects of lifestyle types according to Gunnar Otte, library use and position within the family or life cycle as influencing factors. The expressed willingness-to-pay of the population will be directly compared with that of the politicians. A ratio of willingness-to-pay and the result-per-resident (an economic value) will be generated and thereby an indicator of value determined.
