Análise da eficiência de contratos de serviços de elevada especificidade terceirizados pela petrobras

The definition of the boundaries of the firms is subject that has occupied the organizational theorists long ago, being the seminal work of Coase (1937) indicated as the trigger for one theoretical evolution, with emphasis on governance structures, which led to a modern theory of incomplete contracts. The Transaction Cost Economics (TCE) and Agency Theory arise within this evolution, being widely used in studies related to the theme. Empirically, data envelopment analysis (DEA) has established itself as a suitable tool for analysis of efficiency. Although TCE argues that specific assets must be internalized, recent studies outside the mainstream of theory show that, often, firms may decide, for various reasons, hire them on the market. Researches on transaction costs face with the unavailability of information and methodological difficulties in measuring their critical variables. There`s still the need for further methodological deepening. The theoretical framework includes classic works of TCE and Agency Theory, but also more recent works, outside the mainstream of TCE, which warn about the existence of strategies in use of specific assets that aren`t necessarily aligned with the classical ideas of TCE. The Brazilian oil industry is the focus of this thesis, that aimed to evaluate the efficiency of contracts involving high specificity service outsourced by Petrobras. In order to this, we made the categorization of outsourced services in terms of specificity, as well the description of services with higher specificity. Then, we verified the existence of relationship between the specificity of services and a number of variables, being found divergent results than those that are preached by the mainstream of TCE. Then, we designed a DEA model to analyze the efficiency in the use of onshore drilling rigs, identified among the services of highest specificity. The next step was the application of the model to evaluate the performance of drilling rigs contracts. Finally, we verified the existence of relationship between the efficiency of contracts and a number of variables, being found, again, results not consistent with the theory mainstream. Regarding to analyze of efficiency of drilling rigs contracts, the model developed is compatible with what is found in academic productions in efficiency of drilling rigs. The results on efficiency show a wide range of scores, with efficiencies ranging from 31.79% to 100%, being low the sample efficiency average. There is consonance between the model results and the practices adopted by Petrobras. The results strengthen the DEA as an important tool in studies of efficiency with possibility to use for analysis other types of contracts. In terms of theoretical findings, the results reinforce the arguments that there are situations in which the strategies of the organizations, in terms of use of assets and services of high specificity, do not necessarily follow what is recommended by the mainstream of TCE

A função social do contrato como concretização de direitos fundamentais nas relações privadas

This dissertation deals with the social function of the contract, based on constitutional principles, especially those relating to fundamental rights. The social function of the contract (general clause) is described in the Civil Code so intentionally generic, no precise criteria to define it. Because of the fluidity of this principle, it is justified its closer study, seeking to assess its various meanings and looking away from the legal uncertainty that an unlimited conceptual vagueness can cause. The social function of the contract arises from a transformation experienced in private law from the inflows received from the Constitutional Law, the result of an evolutionary process by which it became the state structure, leaving the foundations of the classical liberal state and moving toward a vision guided by existential human values that give the keynote of the Welfare State. Arose, then the concern about the effectiveness of fundamental rights in relations between individuals, which is studied from the inapplicability of fundamental rights in private relations (U.S. doctrine of State action), passing to the analysis of the Theory of indirect horizontal effect of fundamental rights (of German creation and majority acceptance), reaching the right horizontal efficacy Theory of fundamental rights, prevailing Brazilian doctrine and jurisprudence. It has also been investigated the foundations of the social contract, pointing out that, apart from the provisions of the constitutional legislation, that base the principle on screen, there have also been noticed foundations in the Federal Constitution, in devices like the art. 1, III, the dignity of the human person is the north of the relationship between contractors. Also art. 3rd, I CF/88 bases the vision of social covenants, equipping it for the implementation of social solidarity, as one of the fundamental objectives of the Republic. Still on art. 170 of the Constitution it is seen as a locus of reasoning in the social function of the contract, the maintenance of the economic order. It is also studied the internal and external aspects of the social function of the contract, being the first part the one that considers the requirement of respect for contractual loyalty, through the objective good faith, as a result of the dignity of the hirer may not be offended by the other through the contract. On the other hand, the external facet of the social function of the contract, in line with the constitutional mandate of solidarity, indicates the need for contractors to respect the rights of society, namely the diffuse, collective and individual third party. In this external appearance, it is also pointed the notion of external credit protection, addressing the duty of society to respect the contract. There has been shown some notions of the social contract in comparative law. Then, there has been investigated the content of principle study, through their interrelationships with other provisions of private and constitutional law, namely equality, objective good faith, private autonomy and dignity of the human person. We study the application of the social contract in contractual networks as well as the guidance of conservation of contracts, especially those denominated long-term captive contracts, considering the theory of substantive due performance, concluding with an analysis of the social contract in code of Consumer Protection

Dificuldades e/ou facilidades vivenciadas pelos profissionais que compõem a Estratégia de Saúde da Família

Descriptive and quantitative study, with the objective of review the positive and negative aspects experienced by professionals working in the Family Health Strategy (ESF) of Ceará-Mirim town, at Rio Grande do Norte state. The population included 190 healthcare professionals that integrate the family healthcare staff and the data-collection occurred in a meeting at their workplace, with the implementation of a questionnaire. Results were organized in Microsoft Excel spreadsheet software, with descriptive statistical analysis in tables, graphs and tables through frequencies, averages values and standard deviations. There is a predominance of females (n = 137) and higher rates in almost all professions, and higher average age (38.9%, SD = 7.8) and income wage (average = 10) in the medical category. Regarding the more developed activities, for physicians and nurses are the healthcare actions in the Unit, the oral hygiene for dentists, the immunization for auxiliary nurses (Aux-N), educational meeting for the dental office assistants (ACD), and home visitations to community-based health workers (ACS). About the easiness of work, 93.2% said to be presence of professionals with a personal profile in public healthcare; about the difficulties, 86.8% of professionals cited the unavailability of material, followed by salary range reported by nurses (80.9% ), dentists (80.0%), physicians (73.3%), ACS (83.1%), and Aux-N (90.5%). In relation to working conditions, the unavailability of materials was the most mentioned, with the exception of dentists who reported improvement in wages. We still identify among these difficulties: the drugs availability regarded as first grade obstacle by ACS and physicians, the type of contracts in second grade cited by the ACD and dentists and, in third grade, the salary range cited by dentists and auxiliary nurses. It is concluded that the difficulties and easiness faced by ESF professionals are divergent among themselves. For physicians and nurses, whose healthcare actions become directed to specific groups, the individual and the family, their difficulties relate to the unavailability of materials. For dentists, whose actions more quoted were topical application of fluoride and supervised toothbrush, their greatest difficulty is the salary range. As to the Aux-N, ACD and ACS, for all of them the unavailability of materials has hindered the implementation of their activities in ESF

A percepção da fiscalização dos contratos de mão de obra terceirizada pelos agentes envolvidos nesse processo no âmbito da Universidade Federal do Rio Grande do Norte: uma análise sob o modelo do principal-agente

Outsourcing has emerged as one of the new ways of guiding the work. For its advantages and be consistent with the paradigms of managerial reform, outsourcing also started to be used in the Public Administration. However, taking into account the particularities of the latter, some issues are relevant when outsourcing concluded with the State. Gains notoriety, for example, the step of monitoring these contracts, to the extent that, from this activity, we can avoid the negative effects of outsourcing like the fact that the state will pay for labor and wage liens that are obligation of the company providing the services. This study aims to understand the perception that this process is under the Federal University of Rio Grande do Norte, from the point of view of different stakeholders, also explaining the motivations that these agents have to perform the supervisory process. As a theoretical basis was used the Agency Theory, which reinforces the supervisory activities as a necessary means to minimize moral hazard and adverse selection, seeking to understand not only the different motivations tax contracts to properly perform their duties, but also analyze other phenomena arising from this contractual relationship. To achieve the proposed objectives, were taken a literature review and a presentation of how to organize the management and oversight of contracts in UFRN. The methodological procedures included questionnaires and interviews with those involved in the process. After analyzing the results obtained in the survey instruments , and also based on the laws, regulations and instructions governing the procurement process within the UFRN, it was concluded that the process of overseeing the outsourcing of labor contracts in UFRN is not fully institutionalized, some points should be strengthened in order to have the consolidation of this process, highlighting the need for training of UFRN servers that act as tax, the knowledge that the contractual penalties are applied effectively, the need that there is a supervisor of tax of contractors and also the realization of the rotation system of outsourced employees

Testing option pricing with the Edgeworth expansion

There is a well-developed framework, the Black-Scholes theory, for the pricing of contracts based on the future prices of certain assets, called options. This theory assumes that the probability distribution of the returns of the underlying asset is a Gaussian distribution. However, it is observed in the market that this hypothesis is flawed, leading to the introduction of a fudge factor, the so-called volatility smile. Therefore, it would be interesting to explore extensions of the Black-Scholes theory to non-Gaussian distributions. In this paper, we provide an explicit formula for the price of an option when the distributions of the returns of the underlying asset is parametrized by an Edgeworth expansion, which allows for the introduction of higher independent moments of the probability distribution, namely skewness and kurtosis. We test our formula with options in the Brazilian and American markets, showing that the volatility smile can be reduced. We also check whether our approach leads to more efficient hedging strategies of these instruments. (C) 2004 Elsevier B.V. All rights reserved.

Consórcio intermunicipal para gestão ambiental nos municípios de pequeno porte 1 e 2 do nordeste paraense: uma possibilidade para gestão ambiental?

Após a publicação da Lei Complementar Federal no. 140 (LC 140/2011), de 08/12/2011, que definiu as competências dos municípios na gestão de políticas públicas ambientais, surgiu a necessidade de propor ações pelo poder público municipal para sua implementação. Para assegurar a eficácia da referida lei, os municípios deveriam estruturar-se para licenciar e fiscalizar as atividades degradadoras, ou potencialmente degradadoras, em seus territórios. Os órgãos criados no âmbito das políticas municipais ambientais demandariam estruturação física e de pessoal que, por serem onerosas, se tornaram verdadeiros óbices à priorização do gestor para garantir as condições necessárias para a gestão ambiental municipal. Dessa forma, a cooperação entre os entes federados, por intermédio do instrumento de Consórcio Público se apresenta como uma alternativa estratégica para implementação da lei nos municípios de pequeno porte para encaminhamento das questões ambientais. Entende-se que um planejamento territorial regional facilitaria o encaminhamento para solicitação de recursos, bem como para a celebração de contratos e convênios que beneficiassem os municípios consorciados. O presente estudo analisa a Capacidade Institucional de gestão ambiental entre os municípios de Vigia de Nazaré, São Caetano de Odivelas, Santo Antônio do Tauá e Colares e propõe um protocolo de intenções para formalização de um consórcio público para gestão intermunicipal do meio ambiente. De acordo com o IBGE, referidos municípios são de pequeno porte classes 1 e 2, localizados na Região Nordeste do Estado do Pará. No decorrer da pesquisa, após as visitas aos municípios, constatou-se a falta de capacidade institucional para promover a gestão ambiental em seus próprios territórios pelos municípios, como carência de servidores, baixa capacitação, escassez de recursos financeiros, omissões legislativas, inoperância dos conselhos e dos fundos municipais, além de ausência de aparelhamento como viaturas e equipamentos de medição. Por outro lado foi detectado que já ocorreram reuniões entre os gestores municipais para buscar uma solução conjunta para os problemas da região, dada a proximidade territorial e as semelhanças dos seus recursos naturais. Neste passo, ao final se construiu uma proposta para implementação de um consórcio intermunicipal, mediante um termo de cooperação para gestão ambiental integral entre os municípios.

Análise crítica de contratos técnicos como ferramenta para melhoria da gestão da manutenção

Currently, due to the highly competitive search among industries are becoming more tools for managing product that provides higher availability and therefore profitability. Maintenance as a strategic sector and of fundamental importance in business, it seeks to maximize availability and available resources, minimizing costs and waste, which directly impacts the company's results. The present work has as main objective the review of contracts for maintenance services for companies contracted by a chemical company in the Paraíba Valley, since most of its maintenance services are outsourced, and raise these contracts which are more critical and higher risk to the company's success, thus creating a tool for decision-making by maintenance managers in the act of seeking renewals or new contracts to provide services. As a result after drawing up a standard procedure for contracting of services and a better structuring of the same, we developed a method for the calculation of the criticality of the contracts and based on these calculations, charts were prepared which showed that the current scenario of maintenance contracts the company studied. Thus it is possible to evaluate the contracts which are most critical to the success or failure of the company studied, and also pave the way for further studies on how this criticality of a contract can affect the relationship, the contractor x contracted

Reti di contratti e reti di imprese

Il lavoro di ricerca prende le mosse da una premessa di ordine economico. Il fenomeno delle reti di impresa, infatti, nasce dalla realtà economica dei mercati. In tale contesto non può prescindere dal delineare un quadro della situazione- anche di crisi- congiunturale che ha visto coinvolte specialmente le imprese italiane. In tale prospettiva, si è reso necessario indagare il fenomeno della globalizzazione, con riferimento alle sue origini,caratteristiche e conseguenze. Ci si sofferma poi sulla ricostruzione dogmatica del fenomeno. Si parte dalla ricostruzione dello stesso in termini di contratto plurilaterale- sia esso con comunione di scopo oppure plurilaterale di scambio- per criticare tale impostazione, non del tutto soddisfacente, in quanto ritenuto remissiva di fronte alla attuale vis espansiva del contratto plurilaterale. Più convincente appare lo schema del collegamento contrattuale, che ha il pregio di preservare l’autonomia e l’indipendenza degli imprenditori aderenti, pur inseriti nel contesto di un’operazione economica unitaria, volta a perseguire uno scopo comune, l’“interesse di rete”, considerato meritevole di tutela secondo l’ordinamento giuridico ex art. 1322 2.co. c.c. In effetti il contratto ben si presta a disegnare modelli di rete sia con distribuzione simmetrica del potere decisionale, sia con distribuzione asimmetrica, vale a dire con un elevato livello di gerarchia interna. Non può d’altra parte non ravvisarsi un’affinità con le ipotesi di collegamento contrattuale in fase di produzione, consistente nel delegare ad un terzo parte della produzione, e nella fase distributiva, per cui la distribuzione avviene attraverso reti di contratti. Si affronta la materia della responsabilità della rete, impostando il problema sotto due profili: la responsabilità interna ed esterna. La prima viene risolta sulla base dell’affidamento reciproco maturato da ogni imprenditore. La seconda viene distinta in responsabilità extracontrattuale, ricondotta nella fattispecie all’art. 2050 c.c., e contrattuale.

Ein Forschungsreisender als Notbehelf: Hermann von Wissmann und der erste Überseeeinsatz des Deutschen Reichs (1889-1891)

When the German government faced for the first time an irregular war in German East Africa in 1888, it realised that it did not have the necessary means for such a conflict. Hermann Wissmann, an explorer, was therefore given the mandate to form and lead a force of mercenaries that was bound to him personally on the basis of contracts. Although Wissmann was successful in crushing the disturbances, the government of the Reich refused to give him a leading administrative position in the new formed protectorate subordinate directly to the Kaiser. It feared that the entrepreneur of violence, which had up to then been backed up, would not accept the regulations of colonial rule that should be implemented. Soon, however, it became clear that due to entrenched local views on sovereignty and legitimacy it would be difficult to transfer the western European concept of the monopoly of the state on violence to Africa.
