No. of bitstreams: 1 AGEU CAVALCANTE LEMOS JÚNIOR.pdf: 978581 bytes, checksum: 03ea7704706148b7921db7fb5c2eca51 (MD5) Previous issue date: 2013-11-12 / This paper aims to discuss the real meaning of the social function of property provided for in the Federal Constitution, especially taking into account the position of the state, which requires the individual to take a social destination property, including subjecting him to loss right which has on the well if it fulfills its social function, but ultimately does not fulfill the same role, leaving many lands of their property without a specific destination. Thus we sought to demonstrate the impact on society at such negligence, given the various social differences existing in our country, which are constituted as fuel for the emergence of permanent land conflicts. In the content analysis was made substantially of the legal nature of the social function of property and effects arising from it, analyzing it in many ways and if there is a concern and debate about the issue or if there is prospect for a better use of idle properties. An analysis was made of the issue of the rational use of the property as much as the particular state, checking if the competent authorities are fulfilling their role, namely to seek to achieve social justice through rational distribution of land and assign the role social that it is intended. This publication also alternatives for a better policy on the institute, and used as research techniques, secondary sources, ie literary duly cited, and inductive and deductive methods to achieve a positive result and easy to understand this study. / O presente trabalho busca discutir o real significado da expressão função social da propriedade prevista na Constituição Federal, sobretudo levando-se em conta a postura do Estado, o qual exige do particular que dê uma destinação social à propriedade, inclusive sujeitando-o a perda do direito real que possui sobre o bem, caso não cumpra sua função social, porém, acaba por não cumprir o mesmo papel, deixando diversas terras de sua propriedade sem destinação específica. Desta forma buscou-se demonstrar o impacto causado na sociedade ante tal desídia, haja vista as diversas diferenças sociais existentes em nosso país, as quais se constituem como combustível para o surgimento de conflitos de terras permanentes. No conteúdo foi feita uma análise de forma substancial da natureza jurídica da função social da propriedade e os efeitos dela decorrentes analisando-a sob vários aspectos, se está havendo uma preocupação e um debate acerca do tema, ou, se existe perspectiva para um melhor aproveitamento das propriedades ociosas. Foi feita ainda uma análise da questão da utilização racional da propriedade, tanto pelo particular quanto pelo Estado, verificando se as autoridades competentes estão cumprindo seu papel, qual seja, o de buscar alcançar a justiça social através da distribuição racional da terra e atribuir a função social a que esta se destina. Apresentam-se ainda alternativas para uma melhor política a respeito do instituto tendo utilizado como técnicas de pesquisa, fontes secundárias, isto é, obras literárias oportunamente citadas, além de métodos dedutivos e indutivos para se alcançar um resultado positivo e de fácil compreensão do presente estudo.

Promoção do acesso e inovação em saúde: alternativas ao modelo baseado na proteção à proriedade intelectual em discussão na Organização Mundial de Saúde / Promoting access and innovation in health: alternatives to the model based on intellectual property protection within the World Health Organization

Marcela Cristina Fogaça Vieira 23 February 2015 (has links)
O modelo de promoção da inovação em saúde predominante na atualidade é baseado na proteção da propriedade intelectual por meio da concessão de patentes. A patente permite ao seu titular explorar o objeto protegido com exclusividade por um determinado período de tempo, no qual seria obtido o retorno do investimento feito na pesquisa e desenvolvimento do produto. A obtenção de retorno do custo da P&D pela comercialização do produto final, potencializada pelo monopólio conferido pela patente, faz com o que o detentor da tecnologia estabeleça preço de venda elevado. O sistema de patentes potencializa, assim, a maximização de lucros das empresas farmacêuticas, ampliando seu interesse no desenvolvimento de produtos rentáveis e na mercantilização da saúde. Foram identificadas e sistematizadas evidências que demonstram que a aplicação do sistema de patente na área da saúde tem gerado problemas de inovação, ao direcionar recursos de P&D voltados para a produção de produtos rentáveis e não voltados a atender necessidades de saúde; e de acesso, uma vez que o preço elevado excluí milhões de pessoas do consumo do produto. Ficou demonstrada a necessidade de busca de medidas para superação desses problemas. Identificou-se medidas existentes dentro do sistema de patentes que poderiam ser utilizadas para minimizar os problemas identificados em curto e médio prazo, com uma abordagem caso a caso. Optou-se por utilizar uma abordagem sistêmica, demonstrando a necessidade de medidas alternativas ao sistema de patentes para resolução dos problemas identificados a longo prazo. A identificação de medidas alternativas foi realizada por meio da revisão de mais de uma centena de propostas enviadas em chamada aberta e recomendações feitas por diferentes órgãos da Organização Mundial de Saúde no período de 2003 a 2012. As medidas identificadas foram descritas, sistematizadas e analisadas. Conclui-se que a principal proposta atualmente em discussão é a criação de um Fundo Global de P&D, no marco de uma Convenção Global de P&D em saúde, que financiaria a P&D mediante a concessão de prêmios, e não de patentes. Os resultados da P&D seriam tratados como bens públicos, e poderiam ser produzidos por qualquer interessado. Esse modelo visa desvincular os custos da P&D do preço final do produto. Com isso, tem o potencial de solucionar os problemas de inovação e acesso à saúde identificados no sistema de patentes. No entanto, enfrenta grande oposição dos defensores do sistema de patentes, principalmente grandes empresas farmacêuticas interessadas na ampliação da mercantilização da saúde. / The model for promoting innovation in health prevalent nowadays is based on the protection of intellectual property by granting patents. The patent allows the holder to exploit the protected object with exclusivity for a certain period of time, in which he could obtain the return of investment made in research and development. The need to obtain the return of the investments made on R&D by selling the final product, boosted by the monopoly conferred by the patent, allows the patent holder to establish high price. The patent system maximizes profits of pharmaceutical companies, expanding its interest in developing profitable products and in health commodification. We identified and systematized evidence to show that the application of the patent system in the health sector has generated innovation problems, by directing R&D resources to the production of profitable products and not driven by health needs; and access, since the high price excludes millions of product consumption. It was demonstrated the need for seeking measures to overcome these problems. We identified existing measures within the patent system that could be used to alleviate the problems identified in the short and medium term, with a case-by-case approach. We chose to use a systemic approach, demonstrating the need for alternative measures to the patent system to resolve the problems identified in the long-term. The identification of alternative measures was conducted through review of more than a hundred proposals submitted in open call and recommendations made by different bodies of the World Health Organization from 2003 to 2012. The measures identified have been described, systematized and analyzed. It is concluded that the main proposal currently under discussion is the creation of a Global R&D Fund, as part of a Global R&D Convention on health, which would finance R&D by granting prizes, and not patents. The results of R&D would be treated as public goods, and could be produced by any interested party. This model aims to delink the costs of R&D from the final price of the product. Thus, it has the potential to solve the problems of innovation and access to health identified in the patent system. However, it faces strong opposition from advocates of the patent system, especially large pharmaceutical companies interested in expanding health commodification.

Externalidades positivas e o pagamento por serviços ambientais : uma promissora ferramenta de política ambiental / Positive externalities and payments for environmental services: a promising tool of environmental policy

No. of bitstreams: 1 Adelmar Azevedo Regis.pdf: 1651570 bytes, checksum: fea6985b4a975695e6c1917ebcb65ca8 (MD5) Previous issue date: 2015-11-05 / This work analyzes the Payment for Environmental Services (PES) as a promising economic instrument to solve some problems related to environmental degradation and the generation of positive externalities. To achieve such goal, firstly the thesis analyzes concepts of externality and public goods and the main existing theories to tackle market failures, citing three specific environmental principles to combat negative and positive externalities: Polluter-Pays Principle, User-Pays Principle and Principle Protector-Receiver, which is the modern promotional function of law. Then, the thesis conducts a comparative analysis between the command and control instruments and economic instruments and their efficaciousness and cost-effectiveness in environmental preservation. With such a basis built, this work then defines environmental services and their types and promotes a literature review on the theoretical aspects that support PES schemes, as well as addresses two foreign case studies of PSA and some experiences in Brazil. This paper contributes to the theoretical development of the subject, still little explored in literature, and intends to demonstrate that the payment of environmental services is not a magical solution to the environmental crisis and did not appear to replace command and control instruments; it has to be added to current instruments of environmental policy, in order to correct market failures, which do not recognize the inherent value of ecosystem services and the benefits they provide to social welfare. / O trabalho analisa os Pagamentos por Serviços Ambientais (PSA) como um instrumento econômico promissor para resolver alguns problemas relacionados à degradação ambiental e à geração de externalidades positivas. Para tanto, parte primeiramente de uma análise dos conceitos de externalidade e de bens públicos e das principais teorias existentes para combater as falhas de mercado, mencionando os três princípios ambientais específicos para combater as externalidades negativas e positivas: Princípio do Poluidor-Pagador, Princípio do Usuário-Pagador e Princípio do Protetor-Recebedor, que representa a moderna função promocional do Direito. Em seguida, promove uma análise comparativa entre os instrumentos de comando e controle e os instrumentos econômicos e sua eficácia e custo-benefício na preservação ambiental. Construída essa base, definem-se, então, os serviços ambientais e seus tipos, e se realiza revisão da literatura sobre os aspectos teóricos que dão suporte aos esquemas de PSA, inclusive abordando dois casos de sucesso de PSA no exterior e algumas experiências no Brasil. O presente trabalho contribui para o desenvolvimento teórico da temática, ainda pouco explorada na literatura, e tem por escopo demonstrar que o pagamento de serviços ambientais não é uma solução mágica para a crise ambiental e não surgiu para substituir instrumentos de comando e controle, mas para se somar aos atuais instrumentos de política ambiental, com a função de corrigir as falhas do mercado, que não reconhece o valor intrínseco dos serviços ecossistêmicos e os benefícios que eles proporcionam ao bem-estar da sociedade.

殊價慾望規範性之探討

游偉迪, Yu, Wei-Di Unknown Date (has links)
在探討殊價慾望的規範性意義時,必先瞭解殊價慾望在規範意義上的爭議,而欲瞭解其爭議所在,則首先需從殊價慾望的定義與特性著手。然而困難之處就在於,殊價慾望的定義不僅有失明確,且有因人而異、各陳己見的情況,甚至Musgrave本人亦數度更改對殊價慾望意義的認定。 殊價慾望與殊價財在意義與所具備之特性,眾學者認知上的差異性頗大。主要的差異,一為殊價慾望與殊價財之間觀念的混淆,一為對殊價慾望本身意見之分歧。對於前者,Musgrave在說明殊價慾望與殊價財的意義與特性時,有其清楚的區別。因此,依Musgrave的原意,對殊價慾望的探討才應是較為適切的方向。至於後者,則引發了學者之間對於殊價慾望在傳統規範性公共經濟學中,是否具有規範性意義的爭辯。在消費者主權的光環下,嚴守新古典福利經濟學的學者對其提出嚴厲的批判。 在殊價慾望或殊價財意識型態方面爭論不休之餘,已有多位學者進一步探求殊價財是否亦適用極大化福利之模型分析,並藉由特殊的模型設定推導出殊價財的最適條件,計有一、外部性(效用依存性),二、資訊與學習效果,三、社會的偏好,四、社會計劃者,以及五、福利經濟的事後概念。然而這些學者仍舊以財貨之特殊設定來試圖解釋殊價慾望之規範性的方法,可信度方面不得不有所保留;此外,即使較著重於最適條件的推導,但仍因各位學者對於殊價財特性之認知不一,所特殊設計之模型各異,致使其所得出之殊價財最適條件顯然只能適用其所認知之殊價財,實不足以完整涵蓋殊價慾望的真義。 晚近多有學者以不同角度來解釋殊價慾望。他們已認清除非擺脫新古典個人主義所代表之典範,轉移至另一個典範之內探討,方有釐清殊價慾望的可能。包括從個人偏好的分類出發,提出除了個人的私人偏好外,尚有個人之社會偏好,為一種對於整體經濟社會運行法則的偏好。其次,亦有藉由辯證提供殊價財的制度觀點來證明殊價慾望與殊價財的規範性意義,並且認清了除了消費者主權以外,尚存在如選民主權之其他主權。另外,亦有借重哲學思考,以可能性條件論述殊價慾望的滿足,認為殊價慾望必使得經濟學需納入道德正義的考量,因此必為社會經濟學。並將之應用於歸類並支持政府的一些職責,諸如制度上的設計安排,目的在使得自由市場得以運作,並得以有效率地運作,更可以人性化地運作。然而其中仍有許多不足之處,甚至誤解的情形。 問題的癥結確實在於新古典經濟理論的個人主義並不切合實際。真正的個人主義對於社會人行為的分析,是無法與其身處之社會環境以及複雜的人際關係相分離的。因此為了擺脫不合宜的分析方法,首先必需透過解釋學理論的第一人稱觀點解釋決定的形成與選擇,必基於瞭解個人如何認知。因此第一人稱觀點必成為客觀之主觀論者理論,同時社會科學研究者亦必須投入所欲分析的世界。並在輕「均衡」而重「認知」的理解下,考量第一人稱觀點所重視的動機、利益,與人際關係的交互影響,並捨棄於解釋人類行為並無助益之均衡理論、部分的預測行為,以及細瑣的數學推導。 因此,社會科學係研究「社會問題」,即人與人之間關係的研究,對於同時具備「經濟人」與「社會人」的身份的個人,其私人慾望與社會慾望的分類當依人際關係的有無加以區分。並對個人主觀之偏好輔以「第三者評判」,或某種「公共的正確性準則」。另外亦釐清慾望衡量的原則,以及構成原則與衡量法原則之間的不同之處。最後則詳加分析由消費者主權、私人主權,擴展到個人主權,各個主權原則之間的關係,清楚可知消費者主權實非唯一最重要的主權原則。 如此則殊價慾望之內涵已顯露無疑。其包含了利他的慾望、規範強制的慾望,以及集體狀態的慾望。由是可得本文對於殊價慾望意義之重要結論:係殊價慾望決定了財貨的殊價性,而非財貨提供的特性使其成為殊價財。且殊價慾望必涉及個人的社會慾望,亦絕非外部性所足堪解釋,同時並不因所得分配正義的達成而消滅。對於由政府提供滿足殊價慾望之規範性意義,亦因人際關係愈顯疏離的今日,共同的規範若不經由公權力執行,即合法的強制力,勢必已無法約束利害攸關的人際互動,而得到證實。

Global Warming and Our Natural Duties of Justice : A cosmopolitan political conception of justice

Maltais, Aaron January 2008 (has links)
Compelling research in international relations and international political economy on global warming suggests that one part of any meaningful effort to radically reverse current trends of increasing green house gas (GHG) emissions is shared policies among states that generate costs for such emissions in many if not most of the world’s regions. Effectively employing such policies involves gaining much more extensive global commitments and developing much stronger compliance mechanism than those currently found in the Kyoto Protocol. In other words, global warming raises the prospect that we need a global form of political authority that could coordinate the actions of states in order to address this environmental threat. This in turn suggests that any serious effort to mitigate climate change will entail new limits on the sovereignty of states. In this book I focus on the normative question of whether or not we have clear moral reasons to bind ourselves together in such a supranational form of political association. I argue that one can employ familiar liberal arguments for the moral legitimacy of political order at the state level to show that we do have a duty to support such a global political project. Even if one adopts the premises employed by the most influential forms of liberal scepticism to the ideas of global political and distributive justice, such as those advanced by John Rawls and Thomas Nagel, it is clear that the threat of global warming has expanded the scope of justice. We now have a global and demanding duty of justice to create the political conditions that would allow us to collectively address our impact on the Earth’s atmosphere.

Koncesijų taikymo galimybės Lietuvoje / The possibilities to apply the concessions in lithuania

Pereckaitė, Agnė 23 June 2014 (has links)
Per XX a. paskutinius dešimtmečius viešojo ir privataus sektorių santykis gerokai pasikeitė. Tradiciškai viešojo sektoriaus veiklos sričiai priskirtų paslaugų teikimui ar infrastruktūros modernizavimui ir plėtimui imta naudoti viešojo ir privataus sektorių partnerystę. Koncesija yra vienas iš partnerystės modeliu. Ją galima apibūdinti kaip susitarimą tarp viešojo ir privataus sektorių, kurio tikslas sujungti viešuosius ir privačius išteklius, siekiant realizuoti viešosios politikos tikslus. Lietuvoje koncesijos, lyginant su kitomis valstybėmis, yra naujas reiškinys, neturintis tradicijų ir patirties. Viešosios institucijos retai nusprendžia investicijas pritraukti koncesijos sutarčių pagrindu. Šio darbo objektas yra koncesija. Tikslas - išnagrinėti koncesijų taikymo galimybes Lietuvoje. Tikslo pasiekimui iškelti trys uždaviniai, kurie nulėmė darbo struktūrą. Pirmojoje darbo dalyje analizuojant mokslinę literatūrą ir taikant apibendrinimo metodą nagrinėjamos ekonominės – socialinės viešojo ir privataus sektorių partnerystės atsiradimo prielaidos ir partnerystės sąvoka. Antrojoje dalyje, analizuojant viešojo ir privataus sektorių partnerystės taikymo galimybes atliekama mokslinės literatūros ir informacinių šaltinių analizė, taikomas klasifikavimo ir sisteminimo metodas. Trečiojoje darbo dalyje vertinant koncesijų taikymo galimybės atliekamas kokybinis tyrimas, suformuluojami pagrindiniai klausimai, atliekama norminių teisės aktų ir informacinių šaltinių lyginamoji analizė... [toliau žr. visą tekstą] / Infrastructure has been traditionally viewed as a natural monopoly under the management, control, financial responsibility of the central and local government. However, various countries of the world have shown a growing interest in Concessions (one of the Public Private Partnership model) over the last two decades. Concession is arrangement in which the public and private sectors join together to produce and deliver goods and services. It is a sufficiently new phenomenon in Lithuania and some shortcomings are noticeable in its application. The object of this thesis is Concession. The aim of work is to analyze possibilities to apply the concession in Lithuania. Three tasks were established for the realizing the goal meanwhile determining the structure of thesis. In the first part of thesis there is analysed Public Private Partnership, as phenomena, using analysis of academic literature. In the second part, by using analysis of special and statistical literature, there are analysed subjects influencing Public Private Partnership and experience of various countries of the world in the developing Partnership policy. Situation in Lithuania by excluding main prerequisites for developing concessions is analysed in the third part, using qualitative analysis of academic and special literature, laws, conference materials, comparative, case study methods and quantitative analysis by carrying out a survey of Municipalities opinion. Analysis of theoretical and practical aspects has shown... [to full text]

Institutional Designs of Public Goods in the Context of Cultural Property / Institutional Designs of Public Goods in the Context of Cultural Property

Lankau, Matthias 20 November 2013 (has links)
Die vorliegende Arbeit gliedert sich in zwei Teile. Der erste Teil widmet sich der Fragestellung inwiefern formelle Gruppeneigentumsrechte Herkunftsgemeinschaften vor unautorisierten Verwendungen ihrer traditionellen kulturellen Ausdrucksweisen (TKAs) schützen können. Kapitel 2 und 3 führen hierzu einen ökonomischen Vergleich fünf so genannter sui generis Rechte zum Schutz jener TKAs durch und leiten Politikempfehlungen ab. Zum einen bilden die Beiträge eine Rangfolge der Transaktionskosten, die bei Verhandlung über Verwendungen der TKAs entstehen können. Zum anderen vergleichen die Kapitel, ob die Schutzpräferenzen der Ursprungsgemeinschaft durch die Modelgesetze geschützt wären. Hierbei zeigt sich, dass ein Prinzipal-Agenten-Problem auftritt sollten staatliche Behörden über zu viel Verhandlungsmacht verfügen. In diesem Fall werden Bürokraten eher ihre eigenen Interessen als die der Eigentümer der TKAs durchsetzen. Letztendlich existiert zwischen beiden Effekten ein klarer Trade-Off: Je mehr ein Gesetz die Schutzinteressen der Ursprungsgemeinschaften schützt desto höher sind seine Transaktions- und somit sozialen Kosten. Der zweite Teil dieser Arbeit behandelt – auf Basis ökonomischer Laborexperimente – den Fragenkomplex wie Gruppenmitglieder öffentliche Güter im Kontext kulturellen Eigentums – so wie TKAs – bereitstellen. Der Fokus liegt hierbei auf dem Einfluss sozialer Identität auf das Ausmaß an positiver sowie negativer Reziprozität der Individuen als Determinanten der sozialen Wohlfahrt. Die bedingte Kooperation der Gruppenmitglieder sowie das gegenseitige Bestrafungsverhalten untereinander bilden hierfür Maße für positive und negative Reziprozität. Kapitel 4 zeigt, dass Individuen unter dem Einfluss sozialer Identität grundsätzlich divergierende Kooperationspräferenzen abhängig davon mit wem sie interagieren aufzeigen. Auf Basis eines Within-Subject-Designs und mehreren ein-Perioden Spielen in Strategiemethode, zeigt der Beitrag, dass Individuen in identitäts-homogenen Gruppen (In-Group) die Präferenz für eine höhere bedingte Kooperation und weniger Eigennutzorientierung als in einer heterogenen Gruppe (Out-Group) zeigen. Zusätzlich neigen Individuen in heterogenen Gruppen eher zu einem vollständigen Trittbrettfahrerverhalten. Somit könnten Politikinstitutionen, die den Zusammenhalt einer Gruppe betonen, die soziale Wohlfahrt steigern. Auf der Basis eines zehn-Perioden-Spiels zeigt Kapitel 5, dass hauptsächlich vergleichsweise höhere Erwartungen an die Kooperation der Mitglieder in einer In-Group als an die in einer Out-Group Wohlfahrtsgewinne in homogenen Gruppen im Zuge mehrperiodischer Interaktionen auslösen. Die bedingte Kooperation – hier die Erwiderung der eigenen Erwartungen an die Kooperation der Gruppenmitglieder durch eigene Beiträge – ist hingegen in In- und Out- Groups ähnlich. Insgesamt belegt dieser Beitrag somit, dass Erwartungen der Individuen der entscheidende Faktor für das Beitragsverhalten der Gruppenmitglieder unter sozialer Identität ist. Kapitel 6 analysiert inwiefern die Möglichkeit einer gegenseitigen Bestrafung die Kooperationsbereitschaft unter dem Einfluss sozialer Identität ändert. Hierzu verwendet der Beitrag ein-Perioden-Spiele in Strategiemethode sowohl mit als auch ohne Bestrafung. Es zeigt sich, dass die Antizipation einer Bestrafung in heterogenen Gruppen zur größten Anhebung der Kooperationsbereitschaft führt, was am deutlichsten durch das Verhalten der Free-Rider ausgelöst wird. Darüber hinaus hebt die Bestrafungsinstitution unterschiede in der Kooperationsbereitschaft zwischen homo- und heterogenen Gruppen auf, die sich typischer Weise zugunsten homogener Gruppen verlagert. Letztlich deuten die Ergebnisse darauf hin, dass im Vergleich zu einer Situation in der ausschließlich eine Bestrafungsinstitution vorliegt, eine zusätzliche Identitätszuschreibung die Wohlfahrt zusätzlich erhöht. Mit Fokus auf negativer Reziprozität untersucht Kapitel 7 die Frage inwiefern soziale Identität das Bestrafungsverhalten gegenüber Gruppenmitgliedern beeinflusst, die weniger zum öffentlichen Gut beitragen als der Bestrafende. Hier zeigt sich, dass Mitglieder identitäts-homogener Gruppen seltener und in geringerer Höhe bestrafen, als es in heterogenen Gruppen der Fall ist. Darüber hinaus ist das Bestrafungsverhalten in heterogenen Gruppen signifikant stärker durch Ärger-ähnliche Emotionen motiviert als in homogenen Gruppen. Insgesamt zeigt der zweite Teil dieser Dissertation, dass Identitätszuschreibungen sowohl positive als auch negative Reziprozität beeinflussen und somit die soziale Wohlfahrt bei der Bereitstellung öffentlicher Güter – auch im Kontext kulturellen Eigentums – beeinflussen. Diese Ergebnisse sind demzufolge für Verhaltensabschätzungen im Rahmen von Politikempfehlungen relevant, die sich auf Situation mit dem Charakter öffentlicher Güter beziehen.

The economics and externalities of agricultural land in the urban fringe

Stobbe, Tracy 08 August 2008 (has links)
The preservation of agricultural land, especially that which lies close to cities (in the so-called urban fringe), is a concern in many jurisdictions around the world. Agricultural land values change dramatically as farmland is located nearer to urban areas and development pressure has increased on these lands as urban populations have expanded. In British Columbia, Canada, a provincial-wide zoning system forbids the development or non-agricultural use of land without special permission. This system is explicitly designed to protect the capability of the land to produce food in the future, but it also implicitly protects the positive spillovers from agricultural land such as environmental services and open space. Three empirical papers comprise the original research in this dissertation. They seek to answer related questions about agricultural land values in the urban fringe. First, a statistical investigation is conducted into the factors that are associated with successful applications for exclusion from the agricultural zoning system. This study finds that a measure of distance (metres from the main highway) is highly significantly correlated with a parcel’s chances of being excluded. Next, a paper examines the trend of hobby farmers springing up in the urban fringe. Two different models seek to illuminate common trends in the types of parcels that hobby farmers choose, and the price that hobby farmers pay for the land, respectively. This study finds that hobby farmers seem to be very selective about the parcels they choose, likely trying to take advantage of favourable taxation rates for agricultural producers in place in the province. Lastly, a study seeks to understand how residential parcels’ values are influenced by the nearness to and view of agricultural land. Agricultural land in the study does not appear to exhibit an open space premium, though this could be influenced by uncertainty about the future use of the land. All the empirical work in this dissertation utilizes geographic information systems (GIS) technology that allows the calculation of distances to features of interest. Hedonic pricing models and binary choice models are the main statistical tools used.
