No. of bitstreams: 1 Cínthia Simões da Silva - 2018.pdf: 1372146 bytes, checksum: 384414ab25bf737da9481d6a1967b821 (MD5) Previous issue date: 2018-03-26 / A produção pecuária é caracterizada historicamente como principal atividade econômica do Pampa Gaúcho. No entanto, nas últimas décadas com a introdução de novos sistemas de cultivos agrícolas e a diversificação das atividades produtivas nas organizações rurais, áreas tradicionalmente destinadas à produção pecuária deram espaço as lavouras, evidenciando o crescimento das áreas plantadas com grãos, principalmente de soja na metade sul do Rio Grande do Sul. A transformação do cenário produtivo da pecuária, portanto, expõe uma rica realidade empírica para uma análise a partir da Economia Institucional. Assim, o objetivo da dissertação foi analisar as instituições da pecuária de corte e sua influência no avanço da soja na Campanha Gaúcha. A proposta metodológica da dissertação baseou-se na utilização de dados primários. Para a identificação do perfil e das instituições presentes na pecuária da Campanha Gaúcha, aplicou-se um questionário semiestruturado em uma amostra de 95 pecuaristas, sendo destes 53 Pecuaristas Tradicionais e 42 Pecuaristas Sojicultores, entre junho e novembro de 2017. A análise dos dados seguiu técnicas de estatística descritiva, análise fatorial, teste de hipóteses e regressão linear múltipla. Evidenciaram-se algumas similaridades no perfil socioeconômico e produtivo dos pecuaristas amostrados. Os dados primários indicaram que a atividade pecuária é desenvolvida em variadas estruturas fundiárias. O rebanho bovino nas organizações rurais apresenta tamanho diverso e, ainda que ocorra o cultivo de lavouras de soja nas organizações dos Pecuaristas Sojicultores, a atividade pecuária permanece uma importante exploração econômica. Constatou-se que as instituições presentes na nova dinâmica da pecuária da Região da Campanha apresentam conexão com o passado, a cultura e a tradição da atividade. O resultado da análise fatorial exploratória realizada identificou a presença de quatro fatores: as Instituições Comportamentais, Instituições Socioambientais, Instituições Econômicas, e Instituições Organizacionais. Os resultados dos testes de hipóteses identificaram diferenças entre as instituições presentes nas decisões dos Pecuaristas Tradicionais, estas ligadas a instituições comportamentais e socioambientais e ao processo de path dependence, e dos Pecuaristas Sojicultores que apresentaram maiores médias em variáveis de Instituições Econômicas e Organizacionais. Os resultados da regressão linear indicaram influência positiva das instituições econômicas no avanço do cultivo de soja nas organizações. No que diz respeito às instituições comportamentais e socioambientais, o modelo de regressão identificou que quando maior a presença destas instituições no comportamento dos pecuaristas menor é a presença do cultivo de soja nas organizações rurais. Conclui-se que compreender a nova dinâmica estabelecida na pecuária de corte da Campanha Gaúcha significa reconhecer o indivíduo como determinante da escolha de suas atividades produtivas, influenciado pelas suas motivações, hábitos de pensamento e ações coletivas. Reforçando a importância da utilização da abordagem Institucional, assim como das instituições (formais e informais), não apenas como componentes de análise, mas como agente principal nas transformações ocorridas nas organizações e no meio rural. / Livestock production is historically characterized as the main economic activity of the Pampa Gaucho. However, in the last decades with the introduction of new farming systems and the diversification of productive activities in rural organizations, areas traditionally destined to livestock production have given way to crops, evidencing the growth of areas planted with grains, mainly soybeans in half south of Rio Grande do Sul. The transformation of the livestock production scenario, therefore, exposes a rich empirical reality for an analysis based on the Institutional Economy. Thus, the objective of the dissertation was to analyze the institutions of the cattle ranching and its influence on the soybean advance in the Campanha Gaúcha. The methodological proposal of the dissertation was based on the use of primary data. A semi-structured questionnaire was applied to a sample of 95 ranchers, of which 53 Traditional Cattle Raisers and 42 Pecuaristas Sojicultores, between June and November of 2017, were used to identify the profile and the institutions present in the Campanha Gaúcha. Data analysis followed techniques of descriptive statistics, factorial analysis, hypothesis testing and multiple linear regression. Some similarities were observed in the socioeconomic and productive profile of the farmers sampled. The primary data indicated that livestock farming is carried out in a variety of land structures. The cattle herd in the rural organizations presents a diverse size and, although the cultivation of soybean plantations occurs in the organizations of the Soybeans Farmers, the livestock activity remains an important economic exploitation. It was verified that the institutions present in the new dynamics of the livestock of the Region of the Campaign present connection with the past, the culture and the tradition of the activity. The results of the exploratory factorial analysis identified the presence of four factors: Behavioral Institutions, Socioenvironmental Institutions, Economic Institutions, and Organizational Institutions. The results of the hypothesis tests identified differences between the institutions present in the decisions of the Traditional Farmers, these linked to behavioral and socioenvironmental institutions and to the process of path dependence, and the Soybeans Farmers that presented higher averages in variables of Economic and Organizational Institutions. The results of the linear regression indicated a positive influence of the economic institutions in the advance of soybean cultivation in the organizations. Regarding behavioral and socioenvironmental institutions, the regression model identified that the higher the presence of these institutions in the behavior of small farmers is the presence of soybean cultivation in rural organizations. It is concluded that to understand the new dynamics established in the cattle ranching of the Campanha Gaúcha means to recognize the individual as determinant of the choice of his productive activities, influenced by his motivations, habits of thought and collective actions. Reinforcing the importance of using the institutional approach, as well as institutions (formal and informal), not only as components of analysis, but as the main agent in the transformations that occur in organizations and rural areas.

Serviços de mecanização agrícola: atividade meio ou atividade fim? / Agricultural mechanization services: middle activity or main activity?

Mascarin, Ana Luiza Camargo 07 November 2014 (has links)
Ter ou contratar é a questão estratégica abordada na presente dissertação. A pesquisa tem o objetivo de estudar o mercado de serviços agrícolas de mecanização dentro do escopo e dos limites da firma agrícola. A questão a ser investigada focaliza as razões da predominância da opção pela propriedade da frota de equipamentos por parte dos agricultores. Destaca-se que foi feito um recorte com relação às culturas agrícolas para o estudo, os Sistemas Agroindustriais selecionados foram o da cana-de-açúcar e o da soja. Para resolver essa questão é utilizada a Nova Economia Institucional como base teórica. Os conceitos da Economia de Custos de Transação e sua estratégia de economizar nos custos de transação são elementos que fundamentam as hipóteses sobre a escolha dos arranjos institucionais. O cenário das transações é o ambiente institucional e as instituições são as responsáveis pelas regras que as governam; justificando a análise setorial sobre esse mercado de serviços mecanizados. A Teoria do Crescimento da Firma é utilizada para explicar o surgimento desse novo mercado. A análise empírica envolve duas abordagens: a qualitativa e quantitativa. Na qualitativa são analisados os SAG´s da soja e da cana-de-açúcar, em seguida a análise do ambiente institucional e as regras que envolvem a subcontratação no país para então uma análise setorial do mercado de serviços de colheita mecanizada ser elaborada com base no arcabouço teórico. Na abordagem quantitativa é feita uma comparação entre dos custos operacionais da aquisição de colhedoras ou a contratação de serviços de fornecedores externos; seguida de um modelo probit para investigar a relação entre contratar ou não um serviço de colheita mecanizada. Como resultado da analise do ambiente institucional, foi mostrado que existem regras ambíguas em relação à subcontratação, o que desencoraja e por vezes penaliza quem escolhe contratar. A análise setorial do mercado de serviços de colheita mecanizada no SAG da soja e da cana-de-açúcar foi feita por meio de dois estudos de caso. Foram realizadas entrevistas em profundidade com os fornecedores de serviços de colheita mecanizada e stakeholders. Como resultado proeminente da análise constata-se que os serviços surgem de produtores rurais (100%) que já possuíam máquinas e decidiram otimizar seu uso, e também que a maioria (63%) atua informalmente. Esse resultado corrobora a primeira hipótese (H1) sobre o surgimento de serviços da Teoria do Crescimento da Firma. Em seguida na primeira análise quantitativa verifica-se que os custos operacionais de integrar e contratar o serviço são bem próximos se a opção for comprar uma máquina à vista e contratar. Porém quando financiadas a propriedade não se torna boa opção financeira. Na outra etapa quantitativa foi elaborado um modelo econométrico e investigou-se a relação entre contratar ou não um serviço de colheita mecanizada com a especificidade temporal e locacional, contratos anteriores e a influência negativa do ambiente institucional. Do modelo idealizado e do levantamento realizado os resultados são que as hipóteses relacionadas com a especificidade do ativo (H2) e a existência de contratos bem sucedidos no passado (H3) foram validados com grau de significância de 5%. A hipótese relacionada ao ambiente institucional (H4) apesar de ser significante não foi validada, pois tem o efeito oposto ao esperado. Foram utilizados, portanto, dados qualitativos e quantitativos. Concluiu-se como previsto que a maioria dos produtores é integrada verticalmente (67,2%) e que a opção não é financeira e que os custos de transação importam na tomada de decisões. A atenção agora se volta para os próximos passos sugeridos, como expandir o estudo para novas culturas e serviços agrícolas. / Make or contract is the strategic issue addressed in this dissertation. In this thesis I shall investigate the market of agricultural mechanization services within the scope and limits of the agricultural firm. The question to be investigated focuses on the reasons for the predominance of the option for ownership of the equipment by farmers It is emphasized that a cut was made with respect to agricultural crops for the study, the Agribusiness Systems selected were sugarcane and soybeans. To settle this proposition it is used the New Institutional Economics as a theoretical basis. The concepts of Transaction Cost Economics and its strategy to save on transaction costs are elements that underlie the hypotheses on the choice of institutional arrangements. The scenario of transactions is the institutional environment and the institutions are responsible for the rules which govern them; justifying the sectorial analysis of the market for mechanized services. The Theory of the Growth of the Firm is used to explain the emergence of this new market. The empirical analysis involves two approaches: qualitative and quantitative. Qualitative analyzes the SAG\'s of soy and sugarcane, and then the analysis of the institutional environment and the rules surrounding outsourcing in the country for finally a sectorial analysis of the mechanical harvesting services market to be developed based the theoretical framework. In the quantitative approach a comparison is made between the operational costs of acquiring harvesters and contracting external providers; followed by a probit model to investigate the relationship between contracting or not a service of mechanized harvesting. As a result of analysis of the institutional environment, it was shown that there are ambiguous rules regarding subcontracting, which sometimes discourages and penalizes those who choose to hire. A sectorial analysis of the mechanical harvesting services market in SAG of soy and cane sugar was made hrough two case studies. In-depth interviews were conducted with providers and stakeholders of mechanized harvesting services. As a prominent result of the analysis it appears that the services arise from farmers (100%) who had decided to optimize their machines, and also that the majority (63%) operates informally. This result supports the first hypothesis (H1) on the emergence of the Theory of Growth of the Firm services. Then the first quantitative analysis it is found that the operational costs of integrating and contracting services are very close if the option is to buy a machine in cash or to contract. But when financed property does not become a good financial option. In another quantitative step an econometric model was developed and investigated the relationship between to contract or not mechanized harvesting service, related with the temporal and locational specificity, previous contracts and the negative influence of the institutional environment. The idealized model and the survey results are the assumptions related to asset specificity (H2) and the existence of successful contracts in the past (H3) were validated with significance level of 5% The related institutional environment (H4) despite being significant event has not been validated, it has the opposite effect to that expected. Therefore, qualitative and quantitative data were used. It was concluded as planned that most producers are vertically integrated (67.2%) and that the option is not financial and that transaction costs matter in making these decisions. Attention now turns to the next suggested steps such as expanding the study to new crops and agricultural services.

Implementação de estratégias e governança: estudo de múltiplas firmas de distribuição de defensivos agrícolas no Brasil / Strategy implementation and governance: study of distribution system of agricultural agrochemical in Brazil

Marino, Matheus Kfouri 11 October 2005 (has links)
A grande maioria das organizações falha no processo de implementação de estratégias. A farta literatura de administração de empresas evidencia o fenômeno, e desafia os cientistas das organizações a buscarem aprimoramentos para o problema em questão. A presente tese identifica as principais variáveis críticas de sucesso para a implementação de estratégias, e desenvolve uma análise empírica do sistema de distribuição de defensivos agrícolas no Brasil. O referencial teórico empregado inova, ao trazer as abordagens da Economia das Organizações, na vertente da Economia dos Custos de Transação (ECT), para a análise de um problema de governança corporativa, complementando as tradicionais abordagens de Management, adotadas nas disciplinas de Administração Geral. A análise por meio da Economia das Organizações traz o embasamento econômico e a descrição social do comportamento humano aos processos de geração e implementação de estratégias, preenchendo uma lacuna teórica. A ECT desenvolve uma visão contratual do processo de implementação de estratégias, que analisa a relação entre os proprietários e executivos, para o desenvolvimento de ações definidas pelas estratégias. Assim, a tese associa as estruturas de governança minimizadoras dos custos de transação para a implementação de estratégias com as características das diversas organizações. A tese identificou como variáveis críticas de sucesso no processo de implementação de estratégias: i) a presença de gestão contratada, com executivos (gestores contratados) iniciando as estratégias, estrategistas (proprietários) ratificando-as, executivos implementando-as e estrategistas monitorando-as, para organizações complexas; ii) a existência de mecanismos de adaptação do processo de implementação de estratégias; iii) a existência de salvaguardas contratuais em função da necessidade de investimentos em ativos específicos, gerados a partir das estratégias; e iv) a existência de salvaguardas contratuais em função das incertezas do ambiente de negócio. A pesquisa empírica desenvolveu-se por meio de um survey, que analisou o processo de implementação de estratégias em 32 canais de distribuição de defensivos agrícolas no Brasil. Assim, tornou-se possível o desenvolvimento de uma discussão empírica das hipóteses, que evidencia a relevância das variáveis críticas de sucesso identificadas na revisão teórica. Os resultados da pesquisa empírica apontaram, com exceção da restrição ao resíduo do tomador de decisão, para empresas não complexas, que todas as variáveis críticas de sucesso identificadas na revisão teórica apresentaram relação direta e positiva com a performance do processo de implementação de estratégias, variando entretanto, com relação à significância estatística. A variável gestão contratada não apresentou significância estatística, o que se justifica em parte, pela presença de poucas organizações que apresentam profissionais contratados para gerirem as empresas que compõem a amostra, fato que dificultou a análise. Os resultados da pesquisa empírica não podem ser extrapolados para a população, uma vez que a amostra não é aleatória nem representativa. A partir da revisão teórica e das evidências da pesquisa empírica, a tese elaborou uma proposta metodológica que promove o desenvolvimento de estruturas de governança a partir da análise das variáveis críticas de sucesso, que geram eficiência no processo de implementação de estratégias. Foram estruturadas três dinâmicas que exploram as variações do comportamento dos agentes nas organizações, a necessidade de investimentos em ativos específicos em função das estratégias definidas no processo, e o nível de exposição a incertezas do ambiente de negócios das organizações. A tese consolidou um modelo de gestão estratégica e as dinâmicas são focadas na fase de implementação, após a definição das estratégias. / The great majority of organizations fail when it comes to implement strategies. The great amount of literature in business administration shows such a fact, and challenges the scientists of organizations to find improvements to this issue. The following thesis identifies the main critical success variables to implement strategies and comes up with an empirical analysis of the distribution system of agricultural agrochemical in Brazil. The theoretical references employed are innovative, for they bring the approaches of the Economy of Organizations, under the lines of Transactional Costs Economics (TCE), to the analysis of an issue of corporate governance, in addition to the traditional approaches of Management adopted in the subject matters of Business. The analysis through Economy of Organizations has the economic foundation and the social description of human behavior in the processes of generation and implementation of strategies, thus fulfilling a theoretical gap. TCE develops a contractual approach of the strategies implementation process, one which analyzes the relationship between owners and executives to develop actions defined by strategies. Thus, the thesis associates governance structures which are diminishing factors of cost transactions to implement strategies with the characteristics of several organizations. The thesis identified as critical success variables in the process of implementing strategies: i) the presence of contracted management, with executives (contracted managers) initiating the strategies, strategists (owners) ratifying them, executives implementing them and strategists monitoring them in complex organizations; ii) the presence of mechanisms to adapt the process of strategies implementation; iii) the existence of contractual safeguards due to the need for investments in specific assets generated as result of strategies; and iv) the presence of contractual safeguards due to the uncertainties of the business environment. The empirical research was conducted through a survey, which analyzed the process of strategies implementation in 32 agricultural agrochemical distribution channels in Brazil. Thus it was possible to develop an empiric discussion of the hypothesis that demonstrates the relevance of the critical success variables identified in the theoretical review. The results of the empirical survey show, with the exception of the restriction to the remnant of the decision maker for non-complex enterprises, that all critical success variables identified in the theoretical review showed a direct and positive relation with the performance of the process of strategies implementation, but with variations in relation to their statistical significance. The variable contracted management showed no statistical significance, partially due to the existence of few organizations with contracted professionals to manage the companies, a factor which hindered the analysis. The results of the empirical survey cannot be extended to the population, since the sampling is neither aleatory nor representative. With the theoretical review and the evidence presented in the empirical survey the thesis established a methodological proposal that promotes the development of governance structures from the analysis of critical success variables that generate efficiency in the strategies implementation process. Three dynamics were structured which explore the behavioral variations of agents in organizations, the need of investments in specific assets according to the strategies defined in the process and the level of exposure to uncertainties in the business environment of organizations. The thesis consolidated a model of strategic management and the dynamics are focused in the implementation phase, after the definition of strategies.

O papel das instituições na formação e transformação da vitivinicultura da serra gaúcha : possibilidades de interpretações do desenvolvimento rural pela nova economia institucional

Farias, Claudio Vinicius Silva January 2016 (has links)
A tese realiza uma discussão sobre o papel das instituições na formação e desenvolvimento da vitivinicultura da Serra Gaúcha, tendo por base os pressupostos teóricos da Nova Economia Institucional. Partindo de uma análise de base histórica, o estudo se centra nas transformações recentes ocorridas na vitivinicultura da Serra Gaúcha, desde o final da década de 1980. Após uma ampla revisão, se construiu um modelo analítico das principais transformações ocorridas, nos ambientes organizacionais, tecnológicos, competitivos e institucionais. A partir de tais análises, se propôs um conceito de desenvolvimento rural sob a ótica institucional. O que se pode perceber é que tanto as instituições formais quanto informais cumpriram um importante papel na consolidação de um desenvolvimento rural diferenciado na região, tendo na produção familiar de uvas e vinhos a raiz desse processo. Tais instituições, ao longo do tempo, não somente promoveram a melhora do desenvolvimento rural da região, como também afetaram a conformação do próprio Sistema Agroindustrial (SAG) da Vitivinicultura da Serra Gaúcha, responsável por mais de 90% de todo o vinho produzido no Brasil. Em síntese, as instituições criadas a partir do início dos anos 1990, e que continuam se desenvolvendo até a presente data, ajudaram, basicamente, na promoção da ação coletiva dos agentes econômicos do SAG; melhoraram as condições de produtividade, qualidade e de competição, em especial com os players internacionais; têm buscado desenvolver estratégias que privilegiem as economias de escopo, sobretudo entre os pequenos produtores; têm, a partir de programas e projetos específicos (por exemplo, FUNDOVITIS, MODERVITIS, Wines of Brasil etc.), buscado reduzir os custos de transação entre os agentes produtivos, principalmente porque têm auxiliado a melhorar a comunicação entre eles, bem como a qualidade da informação produzida. / The thesis makes a discussion on the role of institutions in training and development of the wine industry of Serra Gaucha, based on the theoretical assumptions of the New Institutional Economics. From a historical basis analysis, the study focuses on recent transformations in the wine industry of Serra Gaucha, since the late 1980s. After an extensive review, an analytical model was built of the major changes that have occurred in organizational, technological, competitive and institutional environments. From these analyzes, a concept of rural development in the institutional perspective was proposed. What can be seen is that both informal and formal institutions fulfilled an important role in the consolidation of a differentiated rural development in the region, and the family production of grapes and wines was the root of this process. Such institutions, over time, not only have promoted the improvement of rural development in the region, but also have affected the conformation of Agroindustrial System (SAG) of Viticulture in Serra Gaucha, responsible for over 90% of all wine produced in Brazil. In summary, the institutions that were created from the early 1990s and that continue being developed, helped basically in: promoting collective action of SAG economic agents; improved productivity conditions, quality and competition, especially with international players; they have sought to develop strategies that favor economies of scope, especially among small producers; they have sought to reduce transaction costs between productive agents as from specific programs and projects (eg FUNDOVITIS, MODERVITIS, Wines of Brazil etc.), mainly because they have helped to improve communication between producers and the quality the information produced.

Karl Polanyi and the Law of Market Society

Frerichs, Sabine January 2019 (has links) (PDF)
Karl Polanyi started his career as a doctor of law and practiced law for a while; but he did not become a legal scholar. As an economic historian, anthropologist, or sociologist, he was concerned with the relation of economy and society. But even though law is an important factor in mediating this relationship, Polanyi gave little attention to the law as such. As part of an endeavour to advance a "Polanyian" economic sociology of law, this article develops the "law of market Society" as an analytical category. For thi s purpose, three argumentative strategies are combined. First, the article draws on The Great Transformation to reconstruct the role of law in the processes of commodification and decommodification. Second, it turns to Marxist scholarship to explore the conceptual link between law and economics and to ponder to what extent law itself can become a commodity. Third, it links Polanyi's approach with American institutionalism, and Commons' work in particular, to show how the evolution of the "law of market Society" can also be understood as a collective enterprise which continuously evolves. It is argued that these perspectives complement each other and help to bring the law back in where it is missing.

Analyse de l'utilisation de la compensation écologique dans les politiques comme outil de conciliation des intérêts économiques et des objectifs de conservation de la biodiversité / Analysis of the use of biodiversity offsetting in public policies as a balancing tool of economic interests and biodiversity conservation objectives

Calvet, Coralie 17 December 2015 (has links)
Les gouvernements se sont récemment engagés à enrayer l’érosion de la biodiversité. Dans ce contexte, la compensation écologique est apparue comme une réponse politique en permettant, en principe, de répondre à l’exigence de conciliation de deux intérêts souvent antagonistes : le développement économique et la conservation de la biodiversité. L’objectif de ce travail de thèse est d’analyser si la compensation écologique peut accomplir cette promesse. J’envisage cette problématique avec trois angles d’analyse complémentaires et de façon interdisciplinaire en mobilisant les apports de l'économie et de l'écologie. Premièrement, dans une approche théorique, je pose la question de la compatibilité du principe de la compensation avec son objectif de conservation de la biodiversité. Je pose ensuite la question de la possibilité d’atteindre l’objectif d’absence de perte nette de biodiversité dans la mise en œuvre de la compensation. Pour cela, j’étudie empiriquement deux mécanismes de compensation au travers de deux cas d’étude français : une banque de compensation, et la contractualisation agro-environnementale. J’utilise principalement les outils de l’économie néo-institutionnelle pour analyser l’efficacité de ces mécanismes pour la réalisation des objectifs écologiques de la compensation. Au travers d'une approche épistémologique, ma troisième interrogation porte sur le rôle des dynamiques politiques dans la diffusion et dans la promotion de la compensation écologique dans la communauté scientifique. L’analyse théorique met en évidence des limites intrinsèques au principe de la compensation pour atteindre ses objectifs de conservation de la biodiversité, notamment au regard de l’impossibilité d’adopter une approche écologique complexe de la biodiversité dans le processus de la compensation. L’étude empirique montre que les modes d’organisation de la compensation comportent également des limites qui obligent à des compromis susceptibles de remettre en cause l’atteinte des objectifs écologiques de la compensation. Ces résultats mettent en évidence le rôle et l’importance des institutions dans la mise en œuvre des compensations, notamment pour limiter l’apparition de comportements opportunistes, responsables des principaux problèmes d’efficacité identifiés. Enfin, l’analyse épistémologique révèle que le développement et la promotion de la compensation écologique répond à un agenda politique principalement porté par les politiques anglo-saxonnes et certains acteurs de conservation. Ainsi, la compensation écologique n’est pas un objet neutre car elle sert à la diffusion d’une certaine idéologie sur la pratique de la conservation de la biodiversité dans le sillage du développement durable et de l’économie verte. Pour conclure, ce travail permet de souligner que la conciliation des intérêts économiques et écologiques constitue une problématique complexe dont la voie du consensus ne semble pas permettre de répondre aux enjeux d’érosion de la biodiversité. La compensation offre en somme une occasion de penser les conditions de possibilités et d’impossibilités de la protection de la nature aujourd’hui. / Governments have recently pledged to halt the loss of biodiversity. In this context, biodiversity offsetting (BO) appeared as a political response by allowing, in principle, to reconcile two often conflicting interests: economic development and biodiversity conservation. The objective of this work is to analyse whether BO can fulfil that promise. I am considering this issue from an interdisciplinary perspective by mobilizing the contributions of economy and ecology and using three complementary approaches. First, in a theoretical perspective, I ask the question of the compatibility of the offsetting principle with its biodiversity conservation goal. Second, in an empirical approach, I investigate the strengths and limits of using BO mechanisms in conservation policies, particularly two specific mechanisms analysed through two French case-studies: habitat bank and agri-environmental contracts. I mainly use the new institutional economics framework to analyse the effectiveness of these mechanisms for achieving the environmental objectives of BO. Finally, I adopt an epistemological approach to question the role of political dynamics in the diffusion and the promotion of BO in the scientific community. The results of the theoretical analysis highlights the inherent limits to the BO principle to achieve its conservation goals, especially with regard to the impossibility to adopt a complex ecological approach to biodiversity in the process of BO. My empirical study shows that the mechanisms of BO also have limitations that force compromises likely to jeopardize the achievement of environmental objectives of BO. These outcomes highlight the role and the importance of institutions in the implementation of BO, especially to provide clear and precise rules in order to limit the emergence of opportunistic behaviours, responsible for the major problems identified. Finally, my epistemological analysis shows that the development and the promotion of BO actually respond to a political agenda driven by the Anglo-Saxon policies and some conservation stakeholders. Overall my work emphasizes that BO is not a neutral object as it serves to spread a certain ideology on the practice of biodiversity conservation through the lens of sustainable development and green economy. Finally, this work allows stressing that reconciling economic and conservation interests is a complex problem that cannot be solved by using idealized consensus. Rather, the concept of BO offers an opportunity to think about the conditions of possibilities and impossibilities of the protection of nature today.

The research is theoretical basis for New Institutional Economics, Economics of Transaction Costs starting with a review of concepts and approaches used in the study of business inside the agribusiness sector. After reviewing the literature, the rice got contextualized in the world, in Brazil and Goiás. Data about production, inventory, marketing, consumer preferences, and also changes in the market were considered in order to justify the work and inform the importance of this commodity as food.Defined and presented the characteristic of the studied object, the next step was the preparation of a questionnaire to verify the sources of transaction costs, its characteristics and the way organizations treat the phenomenon. In the results, applying the methodology described in 22% of industries installed in the State, it was found the standard of competition required by the market; which payment policies of the raw materials implemented by companies; view toward the short term, undercapitalization and low propensity to adopt technological innovations, including a disorganized institutional environment, as a reality for the vast majority of companies researched. Furthermore, consistent with the theory stated, the main sources of transaction costs relate to opportunism and main attributes of transactions: asset specificity, frequency and uncertainty. The analysis indicated that in addition to the main attributes of transactions, the nature of the coordination process implemented occurs, mainly through the market,that industries could improve coordination and reduce costs with the adoption of hybrid instruments of coordination and long and medium term contracts. But despite the lack of an improvement in coordination, Goiás industry gets the best and biggest trading margins for processed rice market in Goiás. This may be a reflection of a market with monopoly characteristics that the leader of the sector practices between producers, distributors and between companies related to the segment. / O trabalho tem por objetivo identificar as principais fontes de custos de transação nas estruturas de governança das indústrias arrozeiras goianas, suas características, bem como a forma como essas organizações reagem a estes fenômenos. A pesquisa tem por base teórica a Nova Economia Institucional, Economia dos Custos de Transação começando com uma revisão de conceitos e abordagens utilizadas no estudo de empresas no setor agroindustrial. Após a revisão de literatura, contextualizou-se o arroz no mundo, no Brasil e em Goiás. Dados sobre a produção, estoque, comercialização, preferências do consumidor, mudanças no mercado foram consideradas com o intuito de justificar o trabalho e informar a importância dessa commodity como alimento. Definidas e apresentadas as característica do objeto estudado partiu-se para a elaboração de um questionário para a verificação das fontes de custos de transação, suas características e a forma como as organizações tratam o fenômeno. Nos resultados, aplicando a metodologia descrita em 22% das indústrias instaladas no estado, foi encontrado o padrão de concorrência estabelecido no mercado; quais as políticas de pagamento das matérias-primas implementadas pelas empresas; visão voltada para o curto prazo, descapitalização e baixa propensão à adoção de inovações tecnológicas, além de um ambiente institucional desorganizado, como uma realidade para a grande maioria das firmas pesquisadas. Além disso, coerentemente com o indicado pela teoria, as principais fontes de custos de transação se relacionam com o oportunismo e com os principais atributos das transações: especificidade de ativo, freqüência e incerteza. A análise indicou que além dos principais atributos das transações, a natureza do processo de coordenação implementado se dá, majoritariamente via mercado, que as indústrias poderiam melhorar sua coordenação e reduzir custos com adoção de instrumentos híbridos de coordenação como contratos de longo e médio prazos, porém apesar da falta de um aprimoramento na coordenação, a indústria goiana consegue as melhores e maiores margens de comercialização de arroz beneficiado no mercado goiano. Isso pode ser o reflexo de um mercado com características de monopólio que a empresa líder do setor exerce entre produtores, distribuidores e entre firmas relacionadas ao segmento.

Provision of environmental goods on private land: a case study of Australian wetlands

Whitten, Stuart Max, Business, Australian Defence Force Academy, UNSW January 2003 (has links)
The management of natural resources located on private lands often involves a perceived conflict between the mix of private and public benefit outputs they produce. Governments have tended to respond through legislation to restrict and redirect private decisions about resource management. However, the legislative response faces a lack of information about the costs and benefits of alternative management and policy instruments. A pertinent example of this debate is the management of wetlands on private lands. The goal in this thesis is to advance the design of policy relating to the production of environmental outputs on private lands. This goal is achieved by first estimating the welfare impacts of alternative private land management strategies on the wider community. These estimates are used as inputs into the development of alternative policy instruments that are then evaluated in terms of their potential cost-effectiveness in influencing private management. Two case studies of wetland management on private land in Australia are presented ??? the Upper South East Region of South Australia, and, the Murrumbidgee River Floodplain in New South Wales. The conceptual approach described in the first part of the thesis includes a description of the resource management problem and the strengths and weaknesses of the alternative decision frameworks widely employed in Australia. Identification of the cause and nature of transaction costs in the management process is the focus in this discussion. The welfare impacts of alternative wetland management strategies are investigated through the construction of a bio-economic model for each of the case study areas. The approach integrates biophysical analysis of changing wetland management with the value society places on wetlands. Outputs from this process are used in the development of a range of policy instruments directed towards influencing wetland management. The impact of poorly quantified and uncertain transaction costs on the potential cost-effectiveness of these options is evaluated using threshold policy analysis. The empirical results show that the perception of a conflict between the private and public values generated by resource management is accurate. For example, scenarios changing wetland management in the Upper South East of South Australia on the Murrumbidgee River floodplain in New South Wales were shown to generate net benefits of $5.2m and $5.1m respectively. Hence, changing wetland management could generate increased community welfare. The potential for these findings to be translated into wetland policy is less conclusive. Policies directed towards wetland management (in part or in whole) incur a range of transaction costs and deliver differential wetland protection benefits. Ten ???best bet??? policies are identified, but more information is required to determine conclusively whether a net benefit results to the wider community when transaction costs are included.

Determinants and effects of central bank independence reforms

Landström, Mats January 2013 (has links)
This thesis consists of four empirically oriented papers on central bank independence (CBI) reforms.    Paper [1] is an investigation of why politicians around the world have chosen to give up power to independent central banks, thereby reducing their ability to control the economy. A new data-set, including the possible occurrence of CBI-reforms in 132 countries during 1980-2005, was collected. Politicians in non-OECD countries were more likely to delegate power to independent central banks if their country had been characterized by high variability in inflation and if they faced a high probability of being replaced. No such effects were found for OECD countries.    Paper [2], using a difference-in-difference approach, studies whether CBI reform matters for inflation performance. The analysis is based on a dataset including the possible occurrence of CBI-reforms in 132 countries during the period of 1980-2005. CBI reform is found to have contributed to bringing down inflation in high-inflation countries, but it seems unrelated to inflation performance in low-inflation countries.    Paper [3] investigates whether CBI-reforms are important in reducing inflation and maintaining price stability, using a random-effects random-coefficients model to account for heterogeneity in the effects of CBI-reforms on inflation. CBI-reforms are found to have reduced inflation on average by 3.31 percent, but the effect is only present when countries with historically high inflation rates are included in the sample. Countries with more modest inflation rates have achieved low inflation without institutional reforms that grant central banks more independence, thus undermining the time-inconsistency theory case for CBI. There is furthermore no evidence that CBI-reforms have contributed to lower inflation variability    Paper [4] studies the relationship between CBI and a suggested trade-off between price variability and output variability using data on CBI-levels, and data the on implementation dates of CBI-reforms. The results question the existence of such a trade-off, but indicate that there may still be potential gains in stabilization policy from CBI-reforms.
