No. of bitstreams: 1 Clênia de Oliveira Pires.pdf: 707674 bytes, checksum: b4276c388f57247620d9631ff43fdd42 (MD5) Previous issue date: 2013-02-26 / UNISINOS - Universidade do Vale do Rio dos Sinos / Esta dissertação teve como objetivo identificar e analisar os fatores determinantes da necessidade de capital de giro corporativa, partindo de teorias robustas de finanças (Theory of Asymmetric Information, Agency Theory, Pecking Order Theory e Theory of Financial Distress) e de estudos empíricos que também tiveram como objeto a NCG. Para isto, este estudo teve como base um painel de dados não balanceado, com informações de 222 companhias brasileiras não financeiras com ações listadas na BM&FBOVESPA e presentes na Base de Dados Compustat, durante um período de 11 anos (2000 a 2010), totalizando 2.278 observações. Foram testadas diferentes variáveis, utilizando-se modelos de regressões lineares de complexidades distintas. A partir dos resultados da regressão final, gerada pelo Painel Dinâmico, foram identificados dez fatores determinantes da necessidade de capital de giro corporativa, todos significantes. O modelo evidencia a importância da NCG do ano anterior na explicação da NCG do ano corrente e mostra que empresas maiores, com vendas mais voláteis, maior fluxo de caixa livre, maior índice de endividamento e em dificuldades financeiras adotam uma necessidade de capital de giro proporcionalmente reduzida, tornando-se mais eficientes na sua gestão do capital de giro. Por outro lado, as evidências mostram que uma maior margem de contribuição, um maior índice market-to-book e a presença de remuneração anual vinculada ao lucro levam a um aumento da necessidade de capital de giro corporativa. Além disso, os resultados sugerem que um menor risco país encoraja o investimento em capital de giro, evidenciando que fatores exógenos a empresa também determinam o volume da sua NCG. Assim, esta dissertação pretende contribuir com pesquisas futuras, visto que é a primeira a investigar os determinantes do investimento líquido em capital de giro operacional sob a ótica de quatro teorias robustas de finanças. / This thesis aims to identify and analyze the determinants of the working capital requirement corporate, from robust theories of finance (Theory of Asymmetric Information, Agency Theory, Pecking Order Theory and Theory of Financial Distress) and empirical studies that also had as object the WCR. Therefore, this study was based on a panel data unbalanced, with information of 222 Brazilian companies non-financial with stocks listed on the BM&FBOVESPA and presents in Compustat Database, for a period of 11 years (2000 to 2010), totaling 2278 observations. We tested different variables, using linear regression models of different complexities. From the results of the final regression, generated by Dynamic Panel, ten factors determinants of the working capital requirement corporate were identified, all significants. The model evidences the importance of WCR last year in explaining the WCR this year and shows that larger companies, with more volatile sales, higher free cash flow, higher debt ratio and financially distressed adopt a working capital requirement proportionally reduced, making it more efficient in its management of working capital. Moreover, the evidence shows that a higher contribution margin, a higher rate market-to-book and the presence of annual compensation tied to earnings lead to an increased working capital requirement corporate. Furthermore, the results suggest that a lower country risk encourages investment in working capital, showing that company exogenous factors also determine the volume of your WCR. Thus, this thesis aims to contribute to future research, since it is the first to investigate the determinants of the net investment in operating working capital from the perspective of four robust theories of finance.

En période de crise financière, les entreprises ont besoin de trésorerie pour réagir efficacement aux aléas et assurer leur solvabilité. Cette thèse se situe à l’interface entre l’opérationnel et la finance pour développer des modèles de planification tactique gérant simultanément les flux physiques et financiers dans la supply chain. Le coût de financement des opérations basé sur le besoin en fond de roulement (BFR) est intégré comme un nouvel aspect financier jamais considéré dans la littérature de lot-sizing. Nous débutons par une extension du modèle EOQ considérant les coûts de financement du BFR. L’objectif est la maximisation du profit. Une quantité de production optimale est obtenue analytiquement ainsi que l’analyse de la sensibilité du modèle. De plus, les comparaisons avec le modèle EOQ et un modèle qui considère le coût du capital sont étudiées. Ensuite, un modèle basé sur un lot-sizing dynamique est établi. La propriété ZIO est démontrée et permet l’utilisation d’un algorithme en temps polynomial. Enfin un scénario multi-niveau à capacité infini est étudié avec une approche séquentielle puis centralisée. La propriété ZIO est prouvée dans ces deux cas. Des algorithmes de programmation dynamique sont utilisés pour obtenir une solution optimale. Cette thèse peut être considérée comme un premier, mais significatif, travail combinant la planification de production et la gestion du besoin en fond de roulement dans des modèles de planification tactique. Nous montrons que les aspects financiers ont un impact significatif sur les plans de production. Les cas étudiés dans cette thèse peuvent être considérés comme des sous-problèmes dans l’étude de scénario plus réalistes. / In financial crisis, companies always need free cash flow to efficiently react to any uncertainties to ensure solvency. Thus, this thesis serves as an interface between operations and finance to develop tactical production planning models for joint management of physical and financial flows in the supply chain. In these models, the financing cost of operation-based working capital requirement (WCR) is integrated as a new financial aspect never before considered in the lot-sizing literature. We first focus on extending the classic EOQ model by considering the financing cost of WCR with a profit maximization objective. The optimal analytic production quantity formula is derived as well as sensitivity analysis of this model. Moreover, a comparison with the EOQ model and with the formula which considers the cost of capital are discussed. Secondly, a dynamic lot-sizing-based, discounted cash flow model is established based on Uncapacitated lot-sizing model. The zero-inventory ordering property is proven valid for this case and a polynomial-time algorithm can thus be established. Thirdly, multi-level and infinite capacity scenario is investigated with both sequential and centralized approaches. The ZIO property is demonstrated valid in both cases. Dynamic-programming based algorithms are constructed in order to obtain an optimal solution. This thesis should be considered as a first, but significant setup of combining production planning and working capital management. It is shown the significant financial consequences of lot-sizing decision on production planning. The cases investigated in this thesis may be tackled as subproblems in the study of more realistic scenarios.
