Determinantes da reserva de caixa das empresas brasileiras

Estudos que investigam as razões do acumulo de caixa e a existência de uma política de gestão ativa do caixa têm ganhado evidência na literatura acadêmica internacional nos últimos anos. As pesquisas que consideram os determinantes do nível de caixa e suas implicações ainda encontram-se em um estágio inicial. Adicionalmente, pesquisas ao redor do mundo têm encontrado elevado nível de caixa acumulado pelas empresas. De acordo com as principais linhas de investigação empírica, três correntes teóricas podem explicar o nível de caixa a partir das variáveis denominadas determinantes: tradeoff theory, pecking order theory e a teoria de agência. Este estudo tem por objetivo investigar empiricamente os determinantes do caixa e identificar a existência ou não de uma política de gestão ativa nas empresas brasileiras. Foi realizada uma pesquisa com amostra de 198 empresas listadas na BOVESPA, no período de 1998 a 2008, totalizando 2178 observações. A pesquisa utilizou modelos econométricos de regressão linear e painel de dados. Com as evidências empíricas encontradas, podemos concluir que a gestão do nível de caixa acumulado é uma importante decisão a ser tomada pelas empresas brasileiras. As teorias que suportam as explicações dos determinantes do nível de caixa podem ser aplicadas de modo complementar ao invés de divergentes.

Essays in corporate risk management

This research investigates the factors that lead Latin American non-financial firms to manage risks using derivatives. The main focus is on currency risk management. With this purpose, this thesis is divided into an introduction and two main chapters, which have been written as stand-alone papers. The first paper describes the results of a survey on derivatives usage and risk management responded by the CFOs of 74 Brazilian non-financial firms listed at the São Paulo Stock Exchange (BOVESPA), and the main evidence found is: i) larger firms are more likely to use financial derivatives; ii) foreign exchange risk is the most managed with derivatives; iii) Brazilian managers are more concerned with legal and institutional aspects in using derivatives, such as the taxation and accounting treatment of these instruments, than with issues related to implementing and maintaining a risk management program using derivatives. The second paper studies the determinants of risk management with derivatives in four Latin American countries (Argentina, Brazil, Chile and Mexico). I investigate not only the decision of whether to use financial derivatives or not, but also the magnitude of risk management, measured by the notional value of outstanding derivatives contracts. This is the first study, to the best of my knowledge, to use derivatives holdings information in emerging markets. The use of a multi-country setting allows the analysis of institutional and economic factors, such as foreign currency indebtedness, the high volatility of exchange rates, the instability of political and institutional framework and the development of financial markets, which are issues of second-order importance in developed markets. The main contribution of the second paper is on the understanding of the relationship among currency derivatives usage, foreign debt and the sensitivity of operational earnings to currency fluctuations in Latin American countries. Unlikely previous findings for US firms, my evidence shows that derivatives held by Latin American firms are capable of producing cash flows comparable to financial expenses and investments, showing that derivatives are key instruments in their risk management strategies. It is also the first work to show strong and robust evidence that firms that benefit from local currency devaluation (e.g. exporters) have a natural currency hedge for foreign debt that allows them to bear higher levels of debt in foreign currency. This implies that firms under this revenue-cost structure require lower levels of hedging with derivatives. The findings also provide evidence that large firms are more likely to use derivatives, but the magnitude of derivatives holdings seems to be unrelated to the size of the firm, consistent with findings for US firms.

Public debt management, monetary policy and financial institutions

Despite the large size of the Brazilian debt market, as well the large diversity of its bonds, the picture that emerges is of a market that has not yet completed its transition from the role it performed during the megainflation years, namely that of providing a liquid asset that provided positive real returns. This unfinished transition is currently placing the market under severe stress, as fears of a possible default from the next administration grow larger. This paper analyzes several aspects pertaining to the management of the domestic public debt. The causes for the extremely large and fast growth ofthe domestic public debt during the seven-year period that President Cardoso are discussed in Section 2. Section 3 computes Value at Risk and Cash Flow at Risk measures for the domestic public debt. The rollover risk is introduced in a mean-variance framework in Section 4. Section 5 discusses a few issues pertaining to the overlap between debt management and monetary policy. Finally, Section 6 wraps up with policy discussion and policy recommendations.

Applying supply chain management models in the banking industry: a brazilian case analysis

The study presents the results and recommendations deriving from the application of two supply chain management analysis models as proposed by the Supply Chain Council (SCOR, version 10.0) and by Lambert (1997, Framework for Supply Chain Management) on the logistics of cash transfers in Brazil. Cash transfers consist of the transportation of notes to and from each node of the complex network formed by the bank branches, ATMs, armored transportation providers, the government custodian, Brazilian Central Bank and financial institutions. Although the logistic to sustain these operations is so wide-ranged (country-size), complex and subject to a lot of financial regulations and security procedures, it has been detected that it was probably not fully integrated. Through the use of a primary and a secondary data research and analysis, using the above mentioned models, the study ends up with propositions to strongly improve the operations efficiency
