O serviço público de saneamento básico tem relevância amplamente reconhecida. Apesar disso, ainda são verificados no Brasil elevados índices de déficit ou de atendimento precário, com situações distintas nas diversas regiões do país. Nesse sentido, o objetivo desta dissertação é (i) apresentar, a partir da perspectiva interdisciplinar da Economia dos Custos de Transação, uma compreensão do serviço público de saneamento básico no Brasil, atualmente regulamentado pela Lei nº 11.445/2007, (ii) avaliar a eficiência do modo de governança majoritariamente utilizado e, (iii) eventualmente, propor desenhos alternativos para a organização da prestação que sejam economicamente superiores em temos de redução de custos de transação para a realização de investimentos necessários ao cumprimento dos objetivos fundamentais definidos no art. 2º, da Lei nº 11.445/2007. A pesquisa adotou como estratégia metodológica a utilização de uma abordagem interdisciplinar de direito, economia e organizações, nos termos da análise econômica da nova economia institucional. A partir o estudo do ambiente institucional básico, com apoio no referencial teórico, observou-se que o mecanismo de governança predominantemente utilizado no serviço público de saneamento básico no Brasil, isto é, delegações a Companhias Estaduais de Saneamento por meio de contratos de longo-prazo (contratos de programa), não favorece a realização de investimentos em ativos específicos (infraestrutura) necessários à prestação e cumprimentos de metas da política. Foi também constatado que existem alternativas de governança viáveis ao desenho predominante, embora a utilização de formas alternativas provavelmente não possua execução viável pelo simples transplante de normas, isto é, pela via formal. A modificação da forma de governança predominante no saneamento básico no Brasil, com a superação do baixo desempenho verificado (low-level equilíbrium), não é possível de ser realizada sem custos. Nesse sentido, é necessário superar os custos para o rompimento do path dependence provocado pelo hold up realizado pelas Companhias Estaduais de Saneamento Básico sobre os titulares do serviço público (municípios), bem como os custos para o rompimento do path dependence no direito administrativo brasileiro, o qual restringe o desenvolvimento de uma teoria jurídica da regulação apta a viabilizar a construção de uma governança regulatória adequada à redução dos custos de transação, de modo a tornar viáveis investimentos em ativos de infraestruturas com elevado grau de especificidade.

The current study analyzes the birth and development of two strategic alliances established between shrimp producers in Rio Grande do Norte: the Unipesca and the Coopercam. To achieve this aim, two approaches which, at first sight, could be considered contradictory were used: the Transactional Costs Economy and Embeddedness. The first approach is fundamentally based in the studies of Williamson (1985; 1991; 1996; 1999; 2000; 2002). Embededness, on the other hand, went through the review of a series of authors, such as Burt (1992), Granovetter (1973; 1985), Uzzi (1997), Gulati (1994; 1995; 1997; 1998; 1999; 2000), Nielsen (2005), Ring (2002), Ring and Van de Ven (1994), Zafirovski (2002), among others. To analyze the birth and development of the cooperatives in this study, Gulati s work (1998) was used. This study shows the steps to be studied for a better comprehension of an alliance: the decision of starting an alliance and the choice of the partners, the decision about the governance structure, the evolution of the alliance and the development of the companies which established this partnership. To carry this study out, a study case accordingly to Yin s proposal (2001) was adopted. Semi-structured interviews with pre-defined plots were conducted in two phases: in the beginning of 2006 and in the beginning of 2007. The subjects from the research were, in 2006, representative members of the main associations and corporations, besides the shrimp producers from the state, when the context of the activity was set. In the second phase, in 2007, representative members from the two cooperatives that were listed above were interviewed the president from Coopercam and the marketing manager from Unipesca. Besides these two members, directors from two important organizations in each of these cooperatives were also interviewed, giving out the necessary information for the research. Secondary data was also collected from the Brazilian Association of Crab producers website, as well as from news from important newspapers in RN, such as Tribuna do Norte. The primary data was analyzed in terms of quality, accordingly to the documental analysis technique. Thus, through the data that was collected, it can be concluded that the reasons that motivated the companies to cooperate can be explained in terms of the transactional costs economy. However, the choice of partners is more connected to aspects approached by the social embededness. When aspects related to development and evolution were analyzed, it could be seen that both aspects from TCE and Embededness were vital to explain the development of the cooperatives mentioned

The inclusion of local suppliers in production chains has considerable impact on its performance, but most notably in its main actors. The results of this process may be of different kinds and can be analyzed from economic or institutional approaches. This study aimed to verify the existence of different performances of Petrobras due to the inclusion of local suppliers in the oil and gas production chain in the state of Rio Grande do Norte, from the viewpoints of transaction costs and the Institutional Theory. In order to this, were made the characterization of the PROMINP, the description of its actions and results, the mapping of its institutional context of reference, and identification of results obtained by Petrobras in terms of transaction costs and legitimacy. The theoretical framework is based on authors dealing with industrial concentration, as like Marshall, Krugman, Porter and Schmitz, from the sociological perspective of neoinstitucional theory, as like DiMaggio and Powell and Scott and Meyer, and transaction costs, as like Williamson. This is a qualitative research, with data collection done by consulting secondary fonts and semi-structured interviews with nineteen actors of three groups, namely: actors involved in actions of the program, representatives of enterprises and representative of Petrobras. To analyze the content was used the Suchman s model (1995) for categories associated with strategies of legitimation and fourteen variables associated with the three variables assets specificity, bounded rationality and opportunism (Williamson, 1995, 1989) in the case of transaction costs. The results indicate that PROMINP has achieved its objectives by encouraging the increased participation of local companies in the oil and gas production chain, reflecting in the economic development of the state. The Redepetro/RN, fostered and built upon the interaction of the participants, is presented as a solution of continuity to the participation of enterprises in the chain, after the closure of the actions of the program. PROMINP demands responses to coercive, legislative and regulatory pressures of the organizational field, whose institutional context of reference is wide. From the point of view of legitimacy, through strategies to gain cognitive legitimacy and maintaining pragmatic legitimacy, Petrobras can manipulate the environment, ensuring the compliance of the constituents to their technical and institutional demands. Enterprises, in turn, respond to the demands through compliance with technical demands, mainly through the certification of processes, and cultural changes. There aren t clear gains related to the transaction costs, however, gains in legitimacy can be seen as a cumulative capital that can serve as a competitive differential that generates economic gains. In terms of theoretical findings, it was found that, due to its explanatory power for actions that are difficult to explain only in economic terms, Institutional Theory may be used as theoretical support concurrent with other theories. TCE model has limitations in explaining the program actions. In the case, it s emphasized that Petrobras doesn t seek only economic efficiency, but has in its mission the commitment to social development.

O senso comum de que o investimento em tecnologia deve aumentar a produtividade do trabalho foi questionado por muitos estudos nos últimos anos, que não encontraram correlação positiva entre tais aplicações e as receitas das empresas. Mas foi também apoiado por outros autores que obtiveram provas empíricas de que os retornos desses investimentos deveriam ser medidos por outros indicadores, à parte de dados econômicos setoriais agregados. Procuramos analisar essa dicotomia à luz da Economia da Informação, levantando a hipótese de que as inovações bem planejadas em processos de negócio e na estrutura organizacional, apoiadas pela tecnologia de informação, agregam valor e aumentam a produtividade e eficiência da empresa. Para isso, buscamos centralizar a análise nos custos de transação dos processos de negócio, identificando-os como o núcleo central de qualquer indicador de produtividade com que se possa medir com alguma precisão o impacto de novos insumos ou recursos aplicados aos processos em questão.

O objetivo deste trabalho é estudar o impacto proporcionado pelo comércio eletrônico, através do instrumento denominado Business-to-Business, nos Custos de Transação das empresas do setor varejista do Rio Grande do Sul. O trabalho se propõe analisar a abrangência teórica dos Custos de Transação, com uma rápida abordagem sobre a análise da chamada corrente Neo-Institucional. Contudo, para chegar a esta meta principal o estudo vai primeiramente fazer uma incursão pelas abordagens teóricas da teoria dos Custos de Transação, clareando para o leitor, quais os preceitos que fundamentam esta teoria. Na seqüência o trabalho faz uma abordagem sobre os instrumentos eletrônicos de troca de informações, comerciais ou não, posteriormente tratando de maneira mais específica à questão do B2B na economia atual. Neste sentido aborda-se as evidências mundiais da aplicabilidade destes instrumentos. Posteriormente o trabalho faz uma ligação entre os CT e o comércio eletrônico, para determinar corretamente onde o trabalho pretende chegar. Como o trabalho pretende analisar o caso de empresas, nosso estudo primeiramente caracterizou o setor varejista à que as empresas pertencem, para na seqüência apresentar as firmas e os dados levantados n estudo de caso, que nos propusemos verificar. Diante de arranjo que criamos, encerramos o trabalho, apresentando as conclusões verificadas bem como propostas para estudos futuros.

O trabalho tem por objetivo validar a influência dos formadores de mercado de ações sobre a liquidez, uma proxy capaz de medir os custos de transação no mercado secundário de ações. O desafio de medir corretamente a liquidez teve trabalhos relevantes desde 1984, e recentemente foi alvo de uma revisão geral que comparou diversas medidas e encontrou alguns ganhadores. A proposta do presente trabalho é a de revisitar estas medidas e selecionar a métrica mais adequada ao mercado Brasileiro. Escolhida a proxy mais significativa, será então avaliada a relevância do formador de mercado na determinação dos custos de transação por meio de uma versão modificada da equação econométrica de Sanvicente (2012). Por fim, este trabalho será relevante para identificar se as empresas devem contratar formadores de mercado para suas ações, com o fim de reduzirem os custos da negociação de suas ações.

O presente estudo teve dois objetivos complementares: entender o desenvolvimento da instituição privada Programa Integrado de Desenvolvimento e Qualificação de Fornecedores (Prodfor), um programa específico de padronização e certificação de fornecedores locais de produtos e serviços no estado do Espírito Santo; e testar se o programa causou redução de custos de transação para as mantenedoras nas compras de bens e serviços. Foram utilizados os conceitos da nova economia institucional para desenvolver hipóteses a respeito do impacto da certificação sobre o desempenho de compras das empresas mantenedoras. Os resultados da pesquisa de campo e dos testes de média não paramétricos indicam que houve redução nos custos de transação das empresas compradoras após a implantação do programa. Complementarmente, verificou-se que houve maior redução nos custos de transação relacionados às atividades posteriores (ex post) às transações de compra em comparação com os custos associados às atividades anteriores à transação de compra (ex ante).

Após atravessar um período de crise, a pecuária gaúcha mostra sinais de recuperação, condicionada à mudanças no comportamento dos agentes integrantes da cadeia produtiva e do macro ambiente econômico e político do país e do mundo. Em face deste novo cenário, este trabalho realiza um estudo sobre a cadeia produtiva de carne bovina no Rio Grande do Sul, enfatizando os custos de transação existentes ao longo da mesma. O trabalho é centrado nos custos de transação praticados pela indústria, que como elo central da cadeia permite inferências para produtores e mercado. O estudo utilizou dados de origem primária coletados em quatro frigoríficos do Rio Grande do Sul, cada qual selecionado por apresentar uma característica particular que os diferencie dos demais, sendo elas: ser uma cooperativa, realizar exportação de carne “in natura”, atuar voltado para o mercado regional e pertencer a uma rede de supermercados. Os dados referem-se às transações praticadas pelos frigoríficos com seus fornecedores e clientes. A formação de alianças e a prática de contratos são algumas das possibilidades de redução nos custos de transação evidenciadas nos resultados deste estudo. Também constatou-se que as transações realizadas com o mercado externo são mais acuradas, em virtude dos requisitos impostos pelos consumidores e regimes alfandegários. Predominam estruturas de governança regidas pelo mercado, mas formas híbridas e hierárquicas começam a surgir, principalmente através de parcerias informais de fornecimento, onde ainda não se verifica plenamente a existência de contratos na regulamentação das transações.

O segmento de refeições coletivas é representado por empresas envolvidas com o fornecimento de refeições para uma clientela definida, posicionando-se como prestadoras de serviços. Esta relação de terceirização constitui-se em uma estrutura híbrida de governança que tem o contrato como garantia para a realização das atividades entre dois atores, correspondendo à corporificação da transação. Este trabalho se propôs a estudar como os contratos de fornecimento de alimentação são negociados, estruturados e geridos, a partir de um referencial fundamentado na Economia dos Custos de Transação. Para tanto, buscou identificar os elementos transacionais e comportamentais envolvidos na relação entre uma empresa de refeições coletivas (Regional-Sul do Brasil da empresa líder mundial do setor) e suas contratantes. No estudo de caso realizaram-se entrevistas semi-estruturadas com os 7 gestores dos contratos. Também analisaram-se os 92 contratos firmados entre a empresa e seus contratantes. Uma análise qualitativa foi realizada utilizando-se o conteúdo das entrevistas. Os contratos originaram uma série de dados dicotômicos, à medida que certas cláusulas se faziam presentes ou não nos contratos. Desta forma, foi possível investigar a presença de correlações entre as variáveis através de análises estatísticas. Os resultados demonstraram que os ativos específicos representam pequenos custos ex-ante e ex-post ao passo que são de responsabilidade apenas da parte contratante e são salvaguardados no contrato. Já no que se refere à incerteza ambiental e ao padrão dos serviços contratados esses são responsáveis por freqüentes renegociações, demandando os maiores esforços para a manutenção da relação O oportunismo não é comum nas relações estudadas, decorrente de cláusulas que protegem os atores de comportamentos de má-fé e da própria reputação dos agentes. Os contratos aceitam situações imprevisíveis e contemplam a possibilidade de renegociações, corroborando a racionalidade limitada dos atores. De forma geral, notou-se um esforço ex-ante para serem minimizados os custos de transação ex-post à medida que são formulados contratos incompletos e ao mesmo tempo flexíveis, garantindo a manutenção da relação entre os atores.
