This series construction will be based on the studies of Wright (2011) and Crump (2016), both of which use researches on the economic agents’ expectations for the main macroeconomic variables in the estimative of the risk premium of the interest market of other countries. After analyzing these studies, explanation models for the difference of the risk premium in the Brazilian interest market were estimated with weekly and monthly frequencies for several maturities of the interest curve. The results of these estimates have showed coefficients of determination varying from 15% to 59% and also indicate that rises in the risk premium of the Brazilian interest market are related to increases in the risk premium and in the expectation of interest in the US market, increases in the brazilian 5 years Credit Default Swap, depreciations in the real exchange rate per US dollar, increases in the volatility of inflation expectations and increases in the implied volatility of the interest rate and foreign exchange market. In addition, it is presented that the type of monetary cycle (rising or falling current interest) also influences the risk premium. / Este trabalho propõe construir uma série histórica para o prêmio de risco do mercado de juros brasileiro e desenvolver um modelo capaz de explicá-lo. A construção dessa série será baseada nos estudos de Wright (2011) e Crump (2016), que utilizam pesquisas sobre as expectativas dos agentes econômicos para as principais variáveis macroeconômicas na estimação do prêmio de risco do mercado de juros de outros países. Após a análise desses estudos, foram estimados modelos de explicação para a diferença do prêmio de risco no mercado de juros brasileiro, em diferença com frequências semanais e mensais para diversas maturidades da curva de juros. Os resultados dessas estimações mostraram coeficientes de explicação ou determinação que variam de 15% a 59% e apontam que elevações no prêmio de risco do mercado de juros brasileiro se relacionam com aumentos no prêmio de risco e na expectativa de juros do mercado norte-americano, aumentos de 5 anos no Credit Default Swap brasileiro, depreciações na taxa de câmbio pronto real por dólar americano, elevações da volatilidade da expectativa de inflação e aumentos na volatilidade implícita do mercado de opções de juros e câmbio. Além disso, apresenta-se que o tipo de ciclo monetário (juros correntes em queda ou alta) também influencia o prêmio de risco.

For a chosen group of risky assets (foreign currencies, stocks, stock indexes, commodities and interest rates), it was calculated the regulatory capital required by BCB under standard approach and compared to the estimated potential losses, according the alternative models. The results evidence a conservative position by BCB related to market risk of foreign currencies and interest rates, being more suitable for commodities and lenient for equities and their respective indexes. It is also possible to observe the existence of regulatory arbitrage, in which there is very low regulatory capital requirement (or no requirement) for certain risky assets portfolios. / Esse trabalho avalia o capital requerido pelo Banco Central do Brasil (“BCB”) das instituições financeiras por ele reguladas, para risco de mercado segundo abordagem padronizada, em comparação com métricas comumente adotadas pela indústria financeira, referentes aos modelos de VaR e Stress-Testing. Para um determinado grupo escolhido de ativos arriscados (moedas, ações, índice de ações, commodities e taxas de juros), foi aplicada a abordagem do BCB para o capital regulatório requerido e comparada com a perda potencial estimada pelos modelos alternativos. Os resultados evidenciam uma postura bastante conservadora por parte do BCB em relação aos riscos de mercado de moedas e taxas de juros, sendo mais ponderada para commodities e leniente para ações e seus respectivos índices. Pode-se também avaliar a existência de arbitragens regulatórias, onde há exigência muito baixa de capital regulatório (ou nenhuma exigência) para determinados portfólios arriscados.

In the first three chapters, we developed methods to extract the yield curve from government and corporate bonds. We measure the performance of such methods in pricing, Value at Risk and forecasting exercises. In its turn, the last chapter brings a discussion about the effects of different metrics of the optimal portfolio on the estimation of a CCAPM model.In the first chapter, we propose a segmented model to deal with the seasonalities appearing in real yield curves. In different markets, the short end of the real yield curve is influenced by seasonalities of the price index that imply a lack of smoothness in this segment. Borrowing from the flexibility of spline models, a B-spline function is used to fit the short end of the yield curve, while the medium and the long end are captured by a parsimonious parametric four-factor exponential model. We illustrate the benefits of the proposed term structure model by estimating real yield curves in one of the biggest government index-linked bond markets in the world. Our model is simultaneously able to fit the yield curve and to provide unbiased Value at Risk estimates for different portfolios of bonds negotiated in this market.Chapter 2 introduces a novel framework for the estimation of corporate bond spreads based on mixture models. The modeling methodology allows us to enhance the informational content used to estimate the firm level term structure by clustering firms together using observable firm characteristics. Our model builds on the previous literature linking firm level characteristics to credit spreads. Specifically, we show that by clustering firms using their observable variables, instead of the traditional matrix pricing (cluster by rating/sector), it is possible to achieve gains of several orders of magnitude in terms of bond pricing. Empirically, we construct a large panel of firm level explanatory variables based on results from a handful of previous research and evaluate their performance in explaining credit spread differences. Relying on panel data regressions we identify the most significant factors driving the credit spreads to include in our term structure model. Using this selected sample, we show that our methodology significantly improves in sample fitting as well as produces reliable out of sample price estimations when compared to the traditional models.Chapter 3 brings the paper “Forecasting the Brazilian Term Structure Using Macroeconomic Factors”, published in Brazilian Review of Econometrics (BRE). This paper studies the forecasting of the Brazilian interest rate term structure using common factors from a wide database of macroeconomic series, from the period of January 2000 to May 2012. Firstly the model proposed by Moench (2008) is implemented, in which the dynamic of the short term interest rate is modeled using a Factor Augmented VAR and the term structure is derived using the restrictions implied by no-arbitrage. Similarly to the original study, this model resulted in better predictive performance when compared to the usual benchmarks, but presented deterioration of the results with increased maturity. To avoid this problem, we proposed that the dynamic of each rate be modeled in conjunction with the macroeconomic factors, thus eliminating the no-arbitrage restrictions. This attempt produced superior forecasting results. Finally, the macro factors were inserted in a parsimonious parametric three-factor exponential model.The last chapter presents the paper “Empirical Selection of Optimal Portfolios and its Influence in the Estimation of Kreps-Porteus Utility Function Parameters”, also published in BRE. This paper investigates the effects on the estimation of parameters related to the elasticity of intertemporal substitution and risk aversion, of the selection of different portfolios to represent the optimal aggregate wealth endogenously derived in equilibrium models with Kreps-Porteus recursive utility. We argue that the usual stock market wide index is not a good portfolio to represent optimal wealth of the representative agent, and we propose as an alternative the portfolio from the Investment Fund Industry. Especially for Brazil, where that industry invests most of its resources in fixed income, the aforementioned substitution of the optimal proxy portfolio caused a significant increase in the risk aversion coefficient and the elasticity of the intertemporal substitution in consumption.

In modern societies, conflicts of interest are usually mitigated by contractual arrangements, in which, if well delineated, provide the right incentives for cooperation. However, contracts are incomplete, especially those of road concessions, characterized by their long duration and high investments, and therefore they are subject to risks. In this scenario of uncertainties, one of the main risks is the demand risk, i.e., the risk of volume of traffic carried out is lower than projected, affecting the continuity and profitability of the project. Therefore, the present evaluates who should bear the risk of demand in road concessions in Brazil: a private entity, which currently supports this risk, a public entity, or both (shared). To answer this question, the Incentive Theory, together with several international case studies, have been analysed. The presente paper categories the need to transfer risk from private to public administration according to the degree of risk criteria, such as demand risk and risk aversion / Concessões rodoviárias são caracterizadas por seu longo prazo de duração e pelos investimentos elevados, estando, portanto, sujeitas a riscos. Nesse cenário de incertezas, um dos principais riscos é o de demanda, i.e., o risco do volume de tráfego realizado ser inferior ao projetado, afetando a continuidade e rentabilidade do projeto. Dessa forma, o objetivo da dissertação é avaliar quem deveria suportar o risco de demanda em concessões rodoviárias: o ente privado, quem atualmente suporta majoritariamente este risco, o poder público ou ambos (compartilhado). Para esclarecer este ponto, o tema foi analisado à luz da Teoria dos Incentivos e foram averiguadas as práticas internacionais adotadas.

Nesse sentido, essa dissertação visa tentar balancear os mecanismos de concessão de liquidez às contrapartes de instituições financeiras em recuperação e a necessidade de buscar soluções para a efetiva recuperação do banco. Nesse sentido, por um lado a permissão ampla para vencimento antecipado de derivativos de balcão permite a concessão de liquidez às contrapartes da instituição insolvente e restringe o risco delas. Entretanto, o vencimento de grandes quantidades de contrato em conjunto pode desestabilizar o mercado, gerar um movimento de vendas forçadas e contagiar outras instituições, aumentando o risco sistêmico. Do outro lado, impedir a liquidação de contratos entre instituições financeiras (caso uma esteja em processo de recuperação) pode gerar crise de liquidez, e por consequência diminuir a quantidade de operações, o que também aumenta o risco sistêmico. Nesse sentido, o que se busca analisar nesse trabalho é como balancear essas duas preocupações e como a criação de um curto stay period pode ajudar na recuperação de instituições financeiras em dificuldades sem impor perdas para suas contrapartes. / This paper aims to analyse what should be the appropriate treatment to over-the-counter derivatives in case of bank insolvency. Whit that in mind, this dissertation aims to balance the liquidity to the counterparts of financial institutions in recovery procedures and seek for effective recovery of the banks. On one hand, the broad permission for early termination of over-the-counter derivatives allows liquidity to the insolvent institution's counterparties and restricts their credit risk. However, the early termination of large contract at the same time can destabilize the market, generate fire sales, and affect other institutions, increasing systemic risk. On the other hand, preventing the settlement of contracts between financial institutions (in case one is in the process of being recovered) can generate a liquidity crisis, and consequently a decrease in the number of operations, which also increases the systemic risk. In this sense, what is sought to analyse in this work is how to balance these two concerns and how the creation of a short stay period can help in the recovery of financial institutions without imposing losses to their counterparts.

The value model results indicated that investors assign a higher value to excess cash held by high-CSR-performance Brazilian firms, but only when they are subject to a stricter shareholder-protection environment (e.g., cross-listed in the United States). This result is in line with the view that managers should use CSR policies to help mitigate conflicts with stakeholders and the firm in a way that is consistent with shareholders’ interests. The weak institutional environment in Brazil would support the opposite result, albeit the positive relation did not hold true when controlled for corporate governance performance, nor for different specifications of cash holdings. The estimation results for the cash holdings determinants model indicated that CSR performance is positively related to corporate governance, supporting a complementary function of the concepts, as well as the negative relation with idiosyncratic risk indicated reduced risk. The positive relation of CSR performance and systematic risk contrasted with the expected reduced sensitivity to market shocks. CSR performance also had a positive direct effect as well as a negative indirect effect via corporate governance on the level of cash, both statistically significant. / Esse trabalho examina os efeitos da performance de Responsabilidade Social Empresarial (RSE) sobre: i) o valor do caixa (modelo de valor) e; ii) como determinante do nível de caixa mantido pelas empresas brasileiras (modelo de determinantes de caixa). Os resultados da estimação do modelo de valor indicam que os investidores atribuem um maior valor para o caixa mantido por empresas brasileiras com alta performance de RSE mas apenas quando essas estão submetidas a um ambiente de proteção ao acionista mais restritivo (e.g., listadas nos Estados Unidos). Esse resultado está em linha com a visão de gestores devem se utilizar das políticas de RSE para ajudar a mitigar conflitos entre os stakeholders e a firma de forma alinhada aos interesses dos acionistas. O fraco ambiente institucional do Brasil suportaria o contrário, entretanto a relação positiva não permanece verdadeira quando controlado pelo nível de governança corporativa, nem por diferentes especificações de caixa. Os resultados do modelo de determinantes de caixa indicam uma relação positiva entre performance de RSE e governança corporativa, suportando a função de complementar dos conceitos, assim como uma relação negativa com o risco idiossincrático indicando reduzido risco. A relação positiva entre a performance de RSE e o risco sistemático contrasta com a esperada redução à sensibilidade a choques do mercado. A performance de RSE também apresentou um efeito direto positivo no nível de caixa assim como um efeito negativo através do seu impacto indireto pela governança corporativa, ambos estatisticamente significativos.

Two hypotheses on credit portfolio sales were tested: 1) promote rating improvement to the remaining portfolio, or 2) drive to financial leverage - with worsening on the remaining portfolio -, controlling for recourse existence and to whom those assets were sold. The sample includes quarterly information from 145 financial institutions from the first quarter 2001 to second quarter of 2008. The results provide empirical evidence that financial institutions use these sales to improve the rating of the remaining credit portfolio, i.e. they transfer, in most cases, low quality assets, assuring good ratings and improving liquidity. Additionally, following Harchaoui and Dionne (2003) proposal - which besides testing, demonstrating that regulatory requirements promote leveraging in high-risk assets – it was observed the relationship between the Basel Index and credit portfolio rating. The conclusions were similar to those found by Dionne and Harchaoui(2003): the more adequate – higher Basel Index - the financial institution, the greater its chances of having a bad quality credit portfolio. / Este estudo analisa se as vendas de carteiras de crédito são utilizadas por instituições financeiras para gestão de risco, de acordo com Stanton(1998) e Murray(2001) ou para captação recursos, como apontado em Cebenoyan e Strahan(2001) e Dionne e Harchaoui(2003). Duas hipóteses foram testadas quanto às vendas de carteira de crédito: 1) implicam em melhor rating na carteira remanescente; ou 2) promovem alavancagem financeira - com piora na carteira remanescente -, controlando para a existência de coobrigação e para quem esses ativos foram transferidos. A amostra inclui informações trimestrais de 145 instituições financeiras do primeiro trimestre de 2001 ao segundo trimestre de 2008. Os resultados oferecem evidências empíricas de que as instituições financeiras utilizam estas vendas para melhora do rating da carteira de crédito remanescente, ou seja, elas transferem, em sua maioria, ativos de baixa qualidade, garantindo bons ratings e melhorando a liquidez. Adicionalmente, seguindo a proposta Dionne e Harchaoui(2003) - que além de testar, evidenciam que exigências regulatórias promovem alavancagem em ativos de alto risco - foi observada a relação entre o Índice de Basiléia e rating da carteira de crédito. As conclusões foram semelhantes às encontradas por Dionne e Harchaoui(2003): quanto mais adequada – maior Índice de Basiléia - uma instituição financeira for, maiores as chances de ela possuir uma carteira de crédito com qualidade ruim.
