Esta tesis utiliza un enfoque experimental para comprender las interacciones dentro de redes y percibir las decisiones causando inversión de preferencia (IP). El Capítulo 1 experimentalmente introduce comunicaciones no vinculantes a un modelo de producción de un bien costoso, que es no excluible entre personas vinculadas en una red. Los resultados muestran que la comunicación de dirección única no mejora coordinación tanto como la comunicación entre conjuntos máximos independientes. El Capítulo 2 analiza experimentalmente un modelo de conflictos bilaterales integrado en redes, donde los oponentes invierten para ganar recursos. Concluye sobre exceso de inversiones comparado a las predicciones de equilibrio. Por último, el Capítulo 3 mira si el efecto dotación inicial resultado de statu quo conduce IP. Esto es analizado por la interrogación de la buena voluntad de cambiar una lotería dotada para otra o pago seguro. En contrario de las predicciones, resultados demuestra que dotaciones son renunciadas con frecuencia. / This thesis uses an experimental approach in understanding group decisions and interactions in networks and perceiving individual decisions causing preference reversal. Chapter 1 experimentally introduces different communication schemes to a production model of a costly good that is non-excludable among individuals linked within a network. Results show that one-way communication is not as efficient as in earlier literature; yet communication among maximal independent sets enhances coordination. Chapter 2 experimentally analyzes a model of multiple bilateral conflicts embedded in networks where opponents invest in conflict technology to win resources. It concludes on tendency to invest in excess of equilibrium predictions. Finally, Chapter 3 looks at whether preference reversal is driven by an endowment effect explanation originating from status quo bias. This is analyzed through questioning individuals' willingness to exchange their endowed lottery for another lottery or sure money. Contrary to the predictions, results show that individuals most often disclaim their endowments.

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.

Nous capturons la décision de contribuer volontairement au bien public en groupe restreint et important, en nous basant sur un classique de l’économie expérimentale. Contrairement aux prévisions, la décision dépend négativement du rendement du bien public en groupe important. Les joueurs percevraient l’enjeu comme faible. La décision dépend positivement, mais trop fragilement, du nombre de bénéficiaires du bien public en groupe restreint et n’en dépend pas en groupe important. La décision dépend toujours négativement de l’avancement du jeu, mais sans convergence vers la stratégie dominante. Le mode de calcul de la rémunération aurait une incidence. La réciprocité et l’aversion à l’iniquité sont toujours absentes. Cela serait lié au fait que les joueurs ne sont pas représentatifs de la population. Dans le sens des prévisions, deux propriétés de l’investissement public se dégagent et concordent avec les décisions observées dans la vie courante. La décision dépend positivement du rendement public en groupe restreint, dans la logique de cet incitatif à contribuer. L’altruisme est présent sous forme de traces en groupe restreint et disparaît en groupe important, désavantagé par la dilution du don. L’éclat chaleureux du don voit sa présence s’accroître en groupe important, favorisé par le changement de nature du don. Nous modélisons ces résultats en nous basant sur l’équilibre Logit. Il s’agit de fonctions de réponse perturbées comprenant différents composants. Les propriétés de ces fonctions rencontrent adéquatement la prise de décision et ont l’avantage de ne pas représenter certains errements empiriques. / We capture decision-making to voluntarily contribute to public good in small and large group, based on a Classic in experimental economics. Contrary to forecasts, decision-making is negatively correlated with Marginal Per Capita Return to investing in the public group in large group. Subjects appear to view the issue as weak. Decision-making is positively correlated, but too weakly, with number of subjects in small group and is not correlated in large group. Decision-making is always negatively correlated with game process, but without convergence to the dominant strategy. The method used in calculating compensation can have an impact. Reciprocity and aversion to inequity are always missing. This can be linked to the fact that subjects are not representative of the true population. In line with forecasts, two properties of public investment emerge and are consistent with decision-making of everyday life. Decision-making is negatively correlated with Marginal per Capita Return in small group, following logic of this incentive to contribute. There are signs of altruism in small group disappearing in larger group, disadvantaged by dilution of Giving. Presence of Warm-Glow Giving increases in large group, supported by changing nature of Giving. We model these results using the Logit equilibrium. It is noisy response functions including different components. Function’s properties properly meet decision-making and have advantage of not modeling some empirical contradictions.

These changes influenced the inclusion of a new approach to public agrarian policies, the Sustainable Territorial Development (STD). The implementation of such programs encourages the construction of participatory spaces that enable the mobilization of a process of co-production of the public goods, i.e. spaces which would allow for a dialogue and the sharing of power and responsibilities between governmental authorities and civil society in the promotion of rural development. The management of these participatory spaces requires public managers to develop new skills and attitudes. Faced with this issue, the present dissertation seeks to answer the following question: In which ways institutional entrepreneurs of CODETER have promoted collective action and mobilized co-production in the management and planning of the rural development of the Santa Catarina mountain range? In order to answer this question, a combined case study strategy was employed which featured diverse techniques of data collection aiming the interpretation of the results. The case study was conducted in the Colegiado de Desenvolvimento Territorial (CODETER) which is located in the Santa Catarina mountain range. CODETER qualifies as na institute that promotes the implementation of STD actions. The analysis of the data was interpreted via the instrument of a range of theoretical lenses. The Theory of Social Skill (FLIGSTEIN, 2009) was used to identify and understand the tactics institutional entrepreneurs used to coordinate and mediate the conflict in planning the territorial development in the context of CODETER. Different paradigms on the phenomenon of collective action were also considered in order to grasp whether there is in fact concerted action in the mountain range of Santa Catarina (CODETER) and what are its main features. Furthermore, based on the concept of co-production of public goods and their variables, we sought to understand to what extent this collective action promotes a new kind of public action, one which would deepen the participation and engagement of civil society with the public problems of the territory. As a result of the field research, the existence of a collective action in the CODETER was confirmed, through which various initiatives that have contributed to rural development of the territory have emerged. A further observation of field research was that the co-production of public goods was occurring, though one of low intensity. Some obstacles observed to co-production in the Collegiate were: disempowerment of some of the players from civil society; uniformity of the represented social groups; and conflicts involving the dispute of resources and institutional interests. Notwithstanding, the co-production is an ongoing process in the CODETER. Currently their advocates display a greater engagement with public issues, a collective understanding of rural development and a deeper sense of belonging to the territory than that prior to the time of implementation of the program. In order that these advances would occur, the role of the institutional entrepreneurs was crucial. They used their social skills to alleviate the limitations of the coproduction process and to promote the legitimacy of the Collegiate in the region. The observed results corroborate the conclusion that the CODETER was institutionalized, becoming a legitimate council in the region, because there was a movement of collective action of different local actors, coordinated by institutional entrepreneurs of the territory / Nas últimas décadas, mudanças estruturais e sociopolíticas ocorreram na esfera pública brasileira, provocadas, principalmente, pelo processo de redemocratização do país. Essas mudanças influenciaram a inserção de uma nova abordagem na agenda das políticas públicas agrárias, o Desenvolvimento Territorial Sustentável (DTS). A implementação de programas governamentais com esse enfoque desafia a constituir espaços participativos que oportunizem a mobilização de um processo de co-produção do bem público, ou seja, que possibilitem o diálogo e o compartilhamento de poderes e responsabilidades entre entidades públicas e da sociedade civil na promoção do desenvolvimento rural. A condução desses espaços participativos exige que os gestores públicos desenvolvam novas habilidades e atitudes. Diante desta problemática, busca-se nessa dissertação responder: De que maneira os empreendedores institucionais do CODETER têm atuado para promover a ação coletiva e mobilizar a co-produção no planejamento e gestão do desenvolvimento rural da Serra Catarinense? Para responder esta questão, foi empregada uma estratégia de investigação de estudo de caso que combinou a utilização de diversas técnicas qualitativas de coleta de dados para orientar a interpretação dos resultados. A pesquisa concentrou-se no Colegiado de Desenvolvimento Territorial (CODETER) da Serra Catarinense, que é um órgão paritário de planejamento e articulação de iniciativas para o DTS. Para embasar a análise, foram utilizadas algumas abordagens teóricas. A teoria da Habilidade Social (FLIGSTEIN, 2009) foi empregada para identificar e compreender as táticas que os empreendedores institucionais utilizaram para coordenar e mediar o conflito no CODETER da Serra Catarinense. Diferentes teorias sobre o fenômeno da ação coletiva também foram considerados para compreender se existe uma ação concertada no Colegiado e quais suas características principais. Além disso, com base no conceito de co-produção do bem público e suas variáveis, buscou-se compreender em que medida essa ação coletiva promove um novo tipo de ação pública, ampliando a participação e o comprometimento da sociedade civil com os problemas públicos do território. Como resultado da pesquisa, constatou-se a existência de uma ação coletiva no CODETER, por meio da qual emergiram diversas iniciativas que contribuíram para o desenvolvimento rural do território. Verificou-se, ainda, a ocorrência de um processo de co-produção do bem público, porém, de baixa intensidade. Alguns dos obstáculos observados para co-produção no Colegiado foram: baixo empoderamento de alguns representantes da sociedade civil; uniformidade dos segmentos sociais representados; e conflitos envolvendo disputas de recursos e interesses institucionais. Contudo, a co-produção é um processo em construção no CODETER. Atualmente, seus representantes possuem um engajamento maior com os problemas territoriais, um significado compartilhado de desenvolvimento rural e um sentimento de pertencimento com o território maior do que o existente na época da sua implantação. Para que esses avanços ocorressem, foi essencial o papel dos empreendedores institucionais que utilizaram suas habilidades sociais para amenizar as limitações do processo de co-produção e promover a legitimação do Colegiado na região. Os resultados observados corroboram que o CODETER se institucionalizou, tornando-se um conselho legítimo no território, porque houve um movimento de ação coletiva dos diferentes atores locais, coordenado por empreendedores institucionais do território

The paper highlights learning and innovations regarding governance of civil society organization (CSO´s) in the current Brazilian context. Governance is understood as the contemporary way of exercising power that articulates diverse views, capacities and resources. The observed innovations were: networked management involving seven CSO´s, operation from the margins of society, establishing an endowment fund to autonomy, shared decision making, working in networks and co-production to solve public problems. The research was carried out between 2012 and 2014 and involved bibliographic and documental research, 20 interviews of members and partners of the network, participant observation and a working group for research design and data analysis. One of the results is a governance map of IVG based on the approach of Community-Engagement GovernanceTM. / Este trabalho sistematiza a experiência do Instituto Padre Vilson Groh (IVG) na construção de um jeito de governança que empodere as pessoas e organizações que se relacionam com a Rede IVG, destacando aprendizagens e inovações em governança de organizações da sociedade civil (OSCs) no atual contexto brasileiro. Governança entendida como modo contemporâneo de exercício de poder que articula diversas visões, capacidades e recursos.

Community foundations are non-profit organisations that aim for a better quality of life in the communities they serve. They connect people and organisations to promote community development. Some of the characteristics of community foundations are (a) they have a board that reflects the diversity of the community; (b) they serve a defined territory; (c) they raise funds from a variety of sources and they are grantmakers; and (d) they seek to build endowments. Due to such characteristics, community foundations have potential to perform the role of convenors and community leaders, roles that indicate they are able to promote coproduction, an approach applied to public administration that consists of a large participation of citizens individually or organised in formal or informal groups in processes of creation, definition, implementation, control, and evaluation of public policies. In coproduction, citizens and public agents share roles and responsibilities. In order to comprehend how community foundations work to promote coproduction of public goods, a case study was undertaken with one Brazilian community foundation, Instituto Comunitário Grande Florianópolis (ICom). Two of the initiatives of ICom which involved coproduction were examined through the analysis of documents and by interviewing public agents and ICom s professionals that participated in the activities. The results of the research show that, in order to promote coproduction, community foundations (a) count on their reputation and history of work and achievements, and look for alliances that contribute to inspire trust in order to bring together other actors that improve the production of public goods; (b) use the influence of their board members; (c) have the ability to use their financial resources to produce results in the short term, building an environment of confidence among the actors involved; (d) define the focus of the initiatives and the public good/service to be produced, in partnership with local actors, and make clear the results to be achieved collectively; (e) community foundations show technical skills; and (f) they are able to conduct the mobilisation of local actors to be engaged in coproduction / A presente dissertação tem por objetivo compreender como as fundações comunitárias atuam na promoção de coprodução do bem público, a partir do estudo de caso de uma organização que atua na região da Grande Florianópolis (SC). As fundações comunitárias são organizações sem fins lucrativos que buscam melhorar a qualidade de vida em uma determinada área geográfica, articulando pessoas e organizações na promoção do desenvolvimento comunitário. Suas principais características são a) seu conselho diretor reflete a diversidade de atores locais; b) atuam em um área geográfica definida; c) mobilizam recursos de diversas fontes e fazem doações; d) buscam formar fundos patrimoniais permanentes. Dadas as suas características, apresentam o potencial de atuar como organizações articuladoras e de assumir o papel de liderança na comunidade. Por isso, as fundações comunitárias parecem estar em posição de atuar promovendo a coprodução do bem público, uma abordagem que consiste na elaboração, delimitação, implementação, controle e avaliação dos bens e serviços públicos, em que se verifica participação e engajamento dos cidadãos individualmente ou por meio de organizações em todas as etapas do processo, compartilhando papéis e responsabilidades com agentes públicos governamentais. Para compreender como as fundações comunitárias atuam na promoção de coprodução do bem público, foi feito um estudo do caso de uma das fundações comunitárias brasileiras, o Instituto Comunitário Grande Florianópolis (ICom), com o exame de sua ação em duas iniciativas nas quais verificou-se coprodução. A partir de entrevistas com agentes públicos governamentais e profissionais da fundação, além da análise de documentos, verificou-se que para a promoção de coprodução são importantes para a fundação comunitária a) sua reputação e histórico, fortalecido pela aliança com parceiros capazes de enriquecer a proposta de ação e de emprestar credibilidade para atrair novos atores à coprodução; b) a influência das lideranças que compõem sua governança; c) a possibilidade de contar com recursos financeiros para fazer doações de maneira ágil, que representam gestos concretos aos demais atores em articulação; d) definição e foco na causa, no bem ou serviço público a ser produzido, em conjunto com atores locais, e com clareza dos resultados a serem alcançados; e) competência técnica; e f) habilidade de conduzir processos de mobilização de atores locais

Microbes live in complex environments where competitive and cooperative interactions occur that dictate their success and the status of their environment. By furthering our understanding of the interactions between microbes, questions into the evolution of cooperation, disease virulence and biodiversity can be addressed. This will help develop strategies to overcome problems concerning disease, socioeconomics and conservation. We use an approach that combines evolutionary ecology theory with genetics and molecular biology to establish and develop model microbial ecological systems to examine feeding strategies, in what has been termed synthetic ecology. Using the model fungal plant pathogen system of rice blast disease, we generated less virulent gene deletion mutants to examine the sociality of feeding strategies during infection and test a nascent virulence reduction strategy based on competitive exclusion. We revealed that the success of the pathogen is unexpectedly enhanced in mixed strain infections containing the virulent wild-type strain with a less virulent gene deletion mutant of the metabolic enzyme invertase. Our finding is explained by interference between different social traits that occur during sucrose feeding. To test the generality of our result, gene deletion mutants of putative proteases were generated and characterised. We found that if virulence related genes acted ‘privately’, as predicted by social theory, the associated mutants would not make viable strains to use for this virulence reduction strategy by competitive exclusion. Our study then went on to study the fitness of digesting resources extracellularly, as many microbes do, given that this strategy is exposed to social exploitation by individuals who do not pay the metabolic costs. This was investigated by developing an experimental system with Saccharomyces cerevisiae. Though internalising digestion could suppress cheats, the relative fitness of opposing strategies was dependent upon the environmental and demographic conditions. Using this polymorphic system, the influence of competitors on the stability of cooperation, and the influence of cheats on the maintenance of diversity were assessed. To test the fitness of internal versus external digestion in a more natural setting, we generated an internally digesting strain of the rice blast fungus. In addition to suppressing cheats, the strain had enhanced fitness and virulence over the wild-type. We propose that this is caused by a shift in a trade-off between yield and rate. We show how a synthetic ecology approach can capture details of the biology underlying complex ecological processes, while having control over the factors that drive them, so that the underlying mechanisms can be teased apart.

Des logiciels Open Source à Wikipédia, la production par les pairs mobilise des centaines de milliers de contributeurs de par le monde. C’est une source importante de création de valeur dans les secteurs très compétitifs de l’information et de la technologie, ainsi qu’une source majeure d’innovation. Au-delà même de son importance économique, l’émergence de la production par les pairs représente une opportunité d’éclairer un certain nombre de questions anciennes et particulièrement ardues dans la littérature d’un jour nouveau. Compte-tenu de la nature souvent non conventionnelle des incitations au travail dans les environnements de production par les pairs, ceux-ci sont particulièrement adaptés à l’étude de l’impact des préférences économiques non standard sur la production de biens publics, à l’analyse de leur rôle en tant que motivations au travail, ainsi qu’à l’évaluation de leurs conséquences en termes d’économie organisationnelle.Ce travail de thèse s'appuie sur un outil d’expérimentation en ligne original (développé et évalué dans le chapitre 1) pour combiner expériences en ligne à large échelle et méthodes computationnelles (i.e. l’extraction systématique de données sur le comportement de terrain des sujets) afin de (i) mener le tout premier test de terrain exhaustif de la théorie de la production privée de biens publics, (ii) étudier l’importance des préférences sociales en tant que motivations au travail au sein d’organisations productives réelles et (iii) procéder aux premiers tests de terrain documentant des comportements endogènes d’appariement des agents économiques au sein d’équipes productives en fonction de leur type coopératif. / From Open Source Software to Wikipedia, peer production involves hundreds of thousands of contributors worldwide. It is an important source of value creation in the most competitive sectors of information and technology, as well as a major source of innovation. Beyond its economic significance, the emergence of peer production also represents an opportunity to shed new lights on a number of longstanding but notably difficult questions in the literature. Given the unconventional nature of many of the work incentives at play in peer production environments, those are particularly well suited for researching the impact of non standard economic preferences on public goods provision, studying their role as work incentives, and assessing their consequences in terms of organizational economics.This Ph.D. work leverages a novel online experimentation tool (developed and assessed in Chapter 1) to combine large-scale online experiments and computational methods (i.e. the systematic extraction of data on subjects’ field behavior) to respectively (i) provide the first comprehensive field test of the theory of the private provision of public goods, (ii) study the importance of social preferences as work motives within real-world productive organizations and(iii) report the first field evidence of endogenous sorting behavior of economic agents within productive teams based on their cooperative types.

Les biens publics mobiliers s’entendent comme l’ensemble des biens mobiliers placés dans une relation juridique patrimoniale avec les personnes publiques. Certes, ils se caractérisent par leur mobilité (comme les biens privés mobiliers), c’est-à-dire une aptitude à la circulation, physique et juridique, vectrice de souplesse et de fragilité, favorable à la dissociation de leurs utilités ; mais la question ici centrale est celle de savoir si la propriété publique est toujours un instrument pertinent pour appréhender cette mobilité. Il s’avère que la propriété publique, lorsqu’elle est sollicitée, exerce potentiellement une force d’attraction efficace sur tous les biens publics mobiliers ; elle permet ainsi de freiner leur circulation. En revanche, une fois le bien capté, la propriété publique ne suffit plus à maîtriser l’intégrité des biens publics mobiliers. Elle n’endigue pas leur délitement et leur évaporation naturels. Elle est même concurrencée par d’autres rapports de droit qui, par des dissociations des utilités des biens, par la déliaison entre propriété et utilisation, conduisent à interroger sa pertinence. / Movable public property shall be understood as the set of personal property placed in a patrimonial legal relationship with public entities. These goods are characterized by their mobility (such as movable private property), that is to say an ability to circulate, physically and legally, a flexibility and fragility medium, favouring the dissociation of their utilities. But the central question remains whether public ownership is still a relevant instrument for understanding this mobility. It turns out that public ownership, when called upon, potentially exerts an effective force of attraction on all movable public property; thus it allows slowing down their circulation. However, once the good’s ownership has been claimed, public property law is not sufficient to monitor the integrity of movable public property. It doesn’t stem their natural crumbling and evaporation. It is even challenged by other legal relationships which, by dissociation of goods’ utilities, and by unbinding ownership and use, lead to question its relevance.

The main aim of this work is to analyze approache of different methods providing public goods in the public interest by municipalities with extended powers in the Czech Republic. In addition to the characteristics of individual methods the work focuses on legislation, particularly the new regulation on public procurement under the Act no. 134/2016 Coll., On public procurement. The aim of this study is to compare internal regulations of local governments for the procurement of small scale, beyond what the law requires. It refers to the release of the required transparency in these processes and the associated increase in administrative burdens for procurers and suppliers of public procurement.
