abstract: This dissertation is a collection of three essays relating household financial obligations to asset prices. Financial obligations include both debt payments and other financial commitments. In the first essay, I investigate how household financial obligations affect the equity premium. I modify the standard Mehra-Prescott (1985) consumption-based asset pricing model to resolve the equity risk premium puzzle. I focus on two channels: the preference channel and the borrowing constraints channel. Under reasonable parameterizations, my model generates equity risk premiums similar in magnitudes to those observed in U.S. data. Furthermore, I show that relaxing the borrowing constraint shrinks the equity risk premium. In the Second essay, I test the predictability of excess market returns using the household financial obligations ratio. I show that deviations in the household financial obligations ratio from its long-run mean is a better forecaster of future market returns than alternative prediction variables. The results remain significant using either quarterly or annual data and are robust to out-of-sample tests. In the third essay, I investigate whether the risk associated with household financial obligations is an economy-wide risk with the potential to explain fluctuations in the cross-section of stock returns. The multifactor model I propose, is a modification of the capital asset pricing model that includes the financial obligations ratio as a ``conditioning down" variable. The key finding is that there is an aggregate hedging demand for securities that pay off in periods characterized by higher levels of financial obligations ratios. The consistent pricing of financial obligations risk with a negative risk premium suggests that the financial obligations ratio acts as a state variable. / Dissertation/Thesis / Doctoral Dissertation Economics 2017

A presente investigação científica discorre acerca da análise comparativa dos segmentos Tradicional, Nível 1, Nível 2 e Novo Mercado da bolsa de valores brasileira. As bases do estudo estão calcadas nas relações entre retornos, risco e prêmios de risco em cada segmento. Para o alcance desse objetivo, foram organizadas carteiras teóricas, cada uma composta por ações de empresas listadas nos segmentos citados do mercado à vista. O intervalo de tempo delimitador dos dados amostrais compreende o período de janeiro de 2005 a dezembro de 2010 e possui características cíclicas - típicas desse ambiente de negócios - de crescimento, de queda brusca provocada pelos efeitos da crise de 2008 e de recuperação lenta na valorização dos preços das ações. Isso enriquece as conclusões ao se examinar comparativamente as referidas carteiras teóricas à luz de ciclos distintos do risco sistemático. As conclusões corroboram parcialmente os fundamentos da governança corporativa ao evidenciar que, de todos os portfolios compostos por empresas que adotam as boas práticas de governança, somente o Novo Mercado de fato gera redução das incertezas, acarretando a diminuição do risco e elevados retornos, absolutos e excessivos, relativamente ao portfolio composto por empresas listadas no Tradicional e à média do mercado, a qual é dada pelo Ibovespa. Os níveis 1 e 2, apesar das empresas que os compõem adotarem regras de governança corporativa, não obtêm resultados de acordo com as expectativas geradas justamente por desenvolverem processos de maior transparência e respeito aos acionistas. As evidências apontam que as razões do fato supramencionado residem no estágio inicial de desenvolvimento no qual se encontram o mercado de ações brasileiro e a economia nacional pós-Plano Real, além de haver número reduzido de empresas listadas principalmente nos níveis 1 e 2. Análises futuras poderão estar mais bem alicerçadas a partir da expansão do mercado, a qual ainda é tímida, embora sejam inquestionáveis seus resultados econômico-financeiros na melhoria do bem-estar social. / This scientific investigation centers on a comparative analysis of the Traditional, Level 1, Level 2 and Novo Mercado listing segments of the Brazilian stock exchange. The study is based on the relationships among the return, risk and risk premium of each segment. For this, theoretical portfolios were created, with each composed of the stocks of companies listed on these segments in the spot market. The time interval of the sample data consists of the period from January 2005 to December 2010 and features the cyclical characteristics (which are typical in this business environment) of growth, the sharp declines caused by the 2008 crisis and the slow recovery in stock prices, with the comparison of these portfolios in the context of the different cycles of systemic risk enriching the conclusions. The conclusions partially corroborate the fundamentals of corporate governance by demonstrating that of all the portfolios formed by companies that adopt good governance practices, only the Novo Mercado in fact generates a reduction in uncertainties, with lower risks and higher absolute and excessive returns in relation to the portfolio formed by companies listed in the Traditional segment and to the industry average, as indicated by the Ibovespa. Although their component companies adopt more stringent corporate governance rules, the Level 1 and 2 segments have not obtained results that are consistent with the expectations they have generated by their adoption of processes marked by greater transparency and respect for shareholders. The evidence suggests that the reasons for this are the initial stage of development of Brazil’s stock market and the country’s economy following the implementation of the Real Plan, as well as the low number of listed companies in the Level 1 and 2 segments. Future analyses could enjoy more solid support due to the market’s growth, which remains timid. However, the financial results unquestionably contribute to improving the well-being of society.

[pt] Neste trabalho, eu busco replicar o modelo somente com taxas de juros ex-posto em Rudebusch e Wu (2004) para a Estrutura a Termo de Taxa de Juros no Brasil, visando extrair dois fatores latentes que expliquem a curva de juros brasi-leira. O modelo faz parte da família dos modelos afins de estrutura a termo, sem arbitragem, com os fatores sendo extraídos através de uma função de máxima ve-rossimilhança e obtidos via Filtro de Kalman. Posteriormente, eu busco uma rela-ção do preço do risco associado a cada choque do vetor de estados com um ativo de risco - medido aqui através do IBOVESPA. / [en] This paper seeks to replicate the yields-only model present in Rudebusch e Wu (2004) for the Brazilian yield curve, aiming to extract two latent factors that explain all the Brazilian yield curve. The model belongs to the family of the no-arbitrage affine models, with the factors being extracted through a maximum likelihood function, with Kalman Filter. Then, the risk price of the state vector is compared with a risk asset.

Utiliza-se como medida da credibilidade, a variação do prêmio de risco de inflação em função de surpresas inflacionárias de curto prazo no índice IPCA. Primeiro evidencia-se que as expectativas inflacionárias de médio prazo são afetadas pelas surpresas inflacionárias, este efeito é causado por dois motivos, a indexação da economia e/ou a falta de credibilidade da autoridade monetária. Em seguida verifica-se que as surpresas inflacionárias também tem efeito sobre o premio de risco de inflação o que indica falta de credibilidade do banco central. / This paper seeks to measure the credibility of the Brazilian Central Bank. It uses as a measure of credibility, the change in the inflation risk premium in terms of short-term inflationary surprises in the IPCA index. At first, it is shown that the medium-term inflation expectations are affected by inflation surprises, this effect is caused by two reasons, the indexation of the economy and/or lack of credibility of the monetary authority. Then it is observed that the inflation surprises also have an effect on the inflation risk premium, which indicates a lack of credibility of the central bank.

The diploma thesis focuses on issuance of the primary bond by non-financial companies on the Prague Stock Exchange (PSE). In the theoretical part were described the main parameters of securities and financial indicators of companies that build the risk premium and discussed options of risk-free base. The application part presents the evaluation of major factors influencing price and bond rates on the example of emissions carried on the PSE.

The Diploma Thesis deals with the problems of an estimate of the discount rate and the single parameters used especially in the two basic methods for its determination: the surcharge (premium) method and the CAPM model. In the first part there are presented the effects which influence the discount rate and thus also the method of its estimate. The second part of the thesis describes the surcharge (premium) method which includes an estimate of the riskfree rate, the risk premiums and the liquidity premium. The third part of the work is devoted to the CAPM model, and it is divided into two chapters. Firstly, the CAPM model is derived in chapter 3. Then, in chapter 4, there are presented the possibilities of estimate of its single parameters and premiums which are most frequently added to the basic CAPM model.

Die Arbeit ANLEIHERATING UND BONITÄTSRISIKO untersucht die Zusammenhänge zwischen dem Rating von Anleihen, dem Risiko dieser Anleihen sowie ihren Risikoprämien (Spreads). Dazu wird in einem ersten Schritt - auf analytischer Ebene - untersucht, wie Ratings vergeben werden und welchen Einschränkungen sie unterliegen. Die wichtigsten Einschränkungen für den Kapitalmarkt hinsichtlich der Ableitung von quantitativen Risikogrößen (Ausfallwahrscheinlichkeit und ggf. Ausfallschwere) sind: Ordinalität und Relativität der verwendeten Skalen; die Zeitverzögerungen bei Ratingänderungen; die Intransparenz, Subjektivität und Urteilsunabhängigkeit des Ratingverfahrens bzw. der Ratingagenturen; die Erstellung von auftragslosen Ratings; die mangelnde Vergleichbarkeit von Ratings (zeitlich, zwischen Emissionen und zwischen Agenturen); die fehlende Äquidistanz von Ratings; das Risiko fehlerhafter Ratings. In einem zweiten Schritt wird empirisch untersucht, in welcher Höhe vom Markt Spreads (Überrenditen gegenüber den als risikolos geltenden Bundesanleihen) - je nach Rating - für bestimmte Anleihen gefordert werden. Datenbasis sind Kupon-Anleihen (ohne Sonderrechte) des DM-Euromarktes mit täglichen Kursen im Zeitraum Januar 1990 bis Dezember 1995. Die Untersuchungen bestätigen die Relativität: Ratings definieren nur im langfristigen Durchschnitt die Renditeabstände zwischen den verschiedenen Klassen. Kurzfristige Veränderungen der Spreads hingegen hängen von Veränderungen des allgemeinen Zinsniveaus und dem Verlauf der Zinsstrukturkurve ab. Diese beiden Größen weisen dabei einen negativen Einfluß auf, d.h. Zinserhöhungen führen zu Verringerungen der Spreads. Grundsätzlich gilt dabei aber, dass diese Effekte umso stärker ausfallen, je geringer die Bonität der Anleihen ist. Zusätzlich hängen die Spreadänderungen auch (positiv) von Veränderungen der Spreads der jeweils anderen Klassen ab. Als mögliche Erklärungsansätze bieten sich für diese Beobachtung auch an, dass der Markt Schwankungen der erwarteten Ausfallwahrscheinlichkeiten antizipiert und/oder Veränderungen der allgemeinen Risikoeinstellung vorliegen.

The diploma thesis occupies with the evaluation of financial health of the company Východočeská plynárenská, a. s. by traditional and less famous methods of financial analysis. It presents suggestions to improvement the company´s financial situation on the basis of financial analysis´s results. Contains a recommendation to use the concept of economic value added as complex tool for evaluation of financial situation.

The income evaluation is one of the basic methods to establish a price of a real estate. It deals with a discount rate. But there is any obligatory methods how to establish the discount rate. The principle of yield property valuation method is the determination of future net profits transferred to the present value. The amount of the discount rate is affected by the large amount of criteria that take into account the risks associated with the property. The risk represents the financial loss which the owner of real estate created if the immovable thing ceased to produce such income, which is calculated in the valuation. But at present experts the risks associated with the real estate does not quantify and discount rate is determined mostly by the professional estimate. The main aim of the Ph.D. Theses is to propose a methodology to more accurately determine the discount rate. This methodology will be based on the free risk rate and risk premiums. The free risk rate shall be determined on the basis of income on government bonds, which are considered the least risky asset. Risk premiums will reflect the technical quality of the property, economy of real estate and legal level of real estate through eleven criteria. The discount rate could be by this methodology simply calculated using the software support of Microsoft Excel.
