Household survey data collected primarily from rural Bangladesh (Multiple Indicator Cluster Survey 2005-2006) is utilized in this paper to identify the important individual, household and district-level factors that influence the decision making process that parents undertake to determine their children’s (between the age of 7 and 14 inclusive) absence rate from school and work intensity. Bivariate Tobit model is used to jointly estimate the absence rate and hours worked equations. The results of the analysis conducted in this paper suggest that an increase in perceived returns on human capital from attending school – as measured by the wage differential between low-skilled and higher-skilled occupations in a given market – negatively impact absence rate in rural Bangladesh. Moreover, results suggest that the education level of the parents has an impact on a child’s absence rate and the number of hours worked in a week. It is found that the higher the education level of the father, the lower the absence rate and the number of hours worked of a child, while higher levels of the mother’s education level is shown to negatively impact the absence rate. It is also found that being the first born child in a household is associated with both higher absence rate from school and greater amount of hours worked per week. With respect to gender, being a girl is found to be associated with a greater number of hours worked. Lastly, household wealth is found to have a U-shaped relationship with both absence rates and number of hours worked; it is negatively associated with both of the dependent variables at lower levels, but has a positive impact on both absence rate and number of hours worked at higher levels. In general, the results detailed in this paper highlight the importance of policies such as the provision of cash stipends to the poorest households, improving the quality of schooling facilities and directed educational schemes meant to eradicate the persistent gender inequality that is hindering truly universal primary education in rural Bangladesh. / Graduate / 0501 / najsaqib@hotmail.com

Investors have historically demanded a return premium for taking on the risk of illiquidity both in terms of characteristic and systematic liquidity risk. Recent research have presented results suggesting that the liquidity premium is diminishing. The increasing popularity of passive investments such as Exchange Traded Funds (ETFs) have been proposed as a driving force for the declining trend. Despite the popularity of ETFs, there is limited research how they impact the financial markets. The purpose of this thesis is to investigate how the liquidity premium has developed in the United States between 1997 and 2016 and to explore if developments in the liquidity premium can be linked to the capital inflow to the United States ETF market. The thesis uses measures of stocks’ spreads and order book depths as proxies for the characteristic and systematic liquidities. The proxies are used to test if liquidity has influenced stock returns over 1-year, 5-years and the entire 20-year period. The empirical results obtained through Fama-MacBeth regressions show that the liquidity premium can fluctuate by both sign and magnitude year by year. The characteristic risk premium is negative and significant for the entire 20-year period and the 1-year regressions suggests a clear negative trend. The systematic liquidity premium on the other hand is positive and significant for the entire 20-year period but the 1-year regressions do not show a clear trend. The empirical results show no statistical significance that ETFs influence the liquidity premium. However, the graphical interpretation of the 1-year regressions suggests that the characteristic liquidity premium is negatively correlated with the growth of ETFs. The negative characteristic premium implies that investors are not being adequately compensated for the risk of illiquidity and should therefore avoid a liquidity-based investing strategy which has generated excess return in the past.

[pt] O Equity Premium Puzzle tem sido muito estudado no mundo desde 1985, ano da publicação do trabalho de Mehra e Prescott. O intuito desta dissertação foi fazer uma análise e avaliação do Equity Premium Puzzle utilizando diferentes contextos vividos na economia brasileira no período de 1990 até 2005. O modelo utilizado foi o do agente representativo com utilidade separável no tempo desenvolvido por Mehra e Prescott (1985). A fim de realizar comparações de resultados foi utilizado também o modelo revisado por Mehra (2003) e um modelo com utilidade tipo Kreps - Porteus com processo de dotação seguindo a cadeia de Markov. / [en] The Equity Premium Puzzle has been very studied in the world since 1985, year of the publication of the work of Mehra and Prescott. The intention of this dissertation was to make an analysis and valuation of the Equity Premium Puzzle being used different contexts lived in the Brazilian economy in the period of 1990 up to 2005. It was used the representative agent model with separable utility in the time developed for Mehra and the Prescott (1985). In order to carry through comparisons of results was used also the model revised for Mehra (2003) and a model with utility type Kreps - Porteus with endowment process having followed the Markov´s chain.

L’immobilier est un actif récalcitrant, hétérogène et illiquide, ces incertitudes constituent l`appréhension du risque en immobilier d`entreprise. Nous suggérons que le risque peut être évaluer à travers une somme de mesure de risque : en premier lieu dans une approche globale de la volatilité, ce que peut nous proposer une analyse de portefeuille, puis dans une approche plus fine, que peut nous donner la prime de risque d`un marché bureau. Notre travail doctoral se propose d’adapter les outils hérités du monde financier à l’évaluation du risque dans les principaux marchés de bureau Européen. Notre thèse sera rédigée en anglais et la question de recherche s`articulera autour de trois grands axes que nous illustrons sous forme d’articles. / The real estate asset class is tangible, heterogeneous and illiquid. It gives a specific investment universe that needs to be understood by investors, because the uncertainties created by this universe compose the risk of real estate investment. We suggest modelling risks across a sum of risk unit appraisal, on one hand, in constructing portfolio analysis, and on the other hand, through the office market risk premium modelling. Our doctoral study proposes to adapt financial theorems to risk modelling in the main European office markets. Our thesis will be written in Englishand its body will be articulated around three axes whereby those will be illustrated under the form of article.

With reference to the existing literature on liquidity, three key questions have emerged during the last several decades: (i) How to measure liquidity in the most efficient way? (ii) What is the empirical pattern in the relation between market liquidity and stock returns? (iii) What are the determinants of the changes in the Return-Liquidity Relationship? This thesis take the above three questions as its principal focus and studies them by undertaking three separate empirical chapters, using a substantial dataset that covers all the listed firms in these four global economies – Germany, the UK, the US and China from 2001 to 2013. The empirical results imply the following: (i) The Transaction-Cost based liquidity measures, particularly the Quoted Proportional Spread, should be regarded as the most representative liquidity measurement. (ii) There is no evidence consistent with a fixed empirical pattern in the Return-Liquidity Relationship across these four countries as market liquidity is preferred in both Germany and UK, while the opposite results have been obtained for the Chinese stock market. That is, higher market leads to higher stock returns in these two European countries as the higher market liquidity facilitates capital movements to more efficient investments. However in China, the huge number of individual investors generates higher market liquidity through speculative trading rather than as a result of value-related investments, which heightens market risk and thus results in a decrease in stock prices. (iii) There is weak evidence that stock market returns have positive determinant effects on both MLIs (the market impact of liquidity on stock returns) and FLIs, (the firm-level impact of liquidity on stock returns) Return-Liquidity relation on market and firm level respectively. While only FLIs are positively correlated with stock market volatility and the inflation rate and negatively affected by the short-term interest rate.

[pt] O presente estudo analisa a relação entre as variáveis Book-to-Market, risco de falência e retornos no mercado acionário brasileiro para um total de 168 firmas da Bovespa no período de Julho 2009 até Junho 2014. Os resultados demonstram que na medida em que a probabilidade de falência e o Book-to-Market aumentam, as empresas brasileiras pagam um prêmio de risco maior. Apesar disto, o fator Book-to-Market quando analisado separadamente, não consegue mostrar uma relação direta com o prêmio de risco, isto é, empresas com alto Book-to-Market (empresas de valor) não necessariamente pagam retornos maiores que as empresas com baixo Book-to-Market (empresas de crescimento). Isto contraria estudos feitos em mercados financeiros desenvolvidos, onde tal relação é estatisticamente significante. / [en] This study analyzes the relationship between the variables Book-to-Market, bankruptcy risk and returns in the Brazilian stock market for a total of 168 Bovespa firms in the period from July 2009 to June 2014. The results demonstrate that as the probability of failure and the Book-to-Market increase, Brazilian companies pay a higher risk premium. Despite this, it was found that the Book-to- Market factor when analyzed separately, is not able to show a direct relationship to the risk premium, that is companies with high Book-to-Market (value companies) do not necessarily pay higher returns than companies with low Bookto- Market (growth companies). This contradicts previous studies done in developed financial markets, where such relationship is statistically significant.

Para esta finalidade foram obtidas as séries históricas da estrutura a termo das curvas de zero cupom de juros nominais e reais. As curvas foram construídas a partir dos valores de mercado dos títulos públicos e metodologia usada pela ANBIMA a partir do modelo de Svensson (1994), a partir da qual foi calculada uma curva de inflações implícitas de onde se obtiveram os prêmios de inflação em relação à mediana das projeções de inflação do relatório de expectativas de mercado do Banco Central do Brasil (Relatório FOCUS). Utilizando-se também de um histórico de taxas cambiais, das marcações a mercado do CDS Brasil de 5 anos e da taxa Selic overnight de onde foi possível a construção de uma base histórica que seria utilizada para a criação de simulações VAR para se estabelecer as relações das inflações implícitas e prêmios de inflação com as demais variáveis de mercado escolhidas, para seis horizontes de tempo: seis meses, nove meses, um ano, dois anos, três anos e quatro anos. Os resultados obtidos mostraram que as variáveis: taxa cambial, taxa pré-fixada, taxa Selic e CDS Brazil de 5 anos causam a inflação implícita e prêmios de inflação, no sentido de Granger. Um segundo ponto observado foram as diferenças entre as respostas do Break Even Inflation Rate (BEIR) e dos prêmios de inflação, por horizonte de tempo, aos impulsos gerados. Primeiramente foi observado que um impulso na taxa cambial gera uma resposta positivo e impacta mais substancialmente as inflações implícitas de longo prazo em detrimento das de curto prazo. Outra conclusão observada é que choques na taxa Selic geram respostas negativas e mais expressivas para os horizontes curtos, dado que mudanças na taxa Selic overnight impactam menos as expectativas de taxas Selic futuras. As respostas das inflações implícitas e prêmios de inflação para impulsos dos juros nominais são positivas e mais relevantes para os prazos longos e os impulsos gerados nos prêmios do CDS Brasil impactaram negativamente as inflações implícitas de maneira praticamente uniforme entre os prazos analisados. / This paper aims to study the relationship between BEIR (Break Even Inflation Rate) and the inflation premiums embeded in the Brazilian public bonds indexed to inflation with foreign exchange rate, interest rates and sovereign default premiums for Brazilian market. To this end, we construct the real interest and nominal interest zero coupon curves using Svensson (1994) methodology and the indicative yields-to-maturity for Brazilian bonds from ANBIMA and we extract the BEIR historical curve from it. Using the historical BEIR curve constructed and the historical inflation expectations from FOCUS Report, disclosed weakly by Brazilian Central Bank, we constructed a historical inflation premiums curve. Basing on the historical of inflation premiums, BEIR, fixed interest rate, foreign exchange rate, CDS premiums and Selic Overnight rate we estimated a VAR (Vector Autoregressive) model for six different maturities (six months, nine months, one year, two years, three years and four years). The results from the VAR models demonstrated that the chosen variables Granger cause inflations premiums and BEIRs, and the results from the IRF (Impulse Response Functions) put in evidence the different responses of BEIR and inflation premiums on different maturities. The response of BEIR and inflation premiums over the foreign exchange rate impulse was positive and more relevant for long term maturities and the BEIR and inflation premiums responses on the fixed rates impulses are positive and more meaningful for long term maturities because higher fixed rates mean more inflation premiums, and the responses over the CDS impulse were negative and at the same level over different maturities.

[pt] A modelagem da estrutura a termo de juros tem atraído atenção crescente de pesquisadores e profissionais de mercado ao longo dos últimos anos, por seu papel central em Finanças como balizadora do custo de capital. A oferta de produtos atrelados à dinâmica de juros vem evoluindo continuamente, tanto em volumes negociados quanto em sofisticação das estruturas, sendo acompanhada por modelos cada vez mais complexos de análise e apreçamento. A alta dimensionalidade do objeto de estudo exige o uso de um ferramental matemático bastante desenvolvido e diferente do utilizado para a análise de outros ativos (ações, por exemplo). Como resultado, temos diversos modelos de curva, não necessariamente reconciliáveis sob um quadro teórico unificado, e alguns eventualmente distantes da prática de mercados específicos. No Brasil o problema de avaliação da ETTJ é ainda mais complexo, tanto pelo rápido amadurecimento do mercado de renda fixa nos últimos dez anos, quanto pela herança de sua evolução histórica, ainda presente nas funções de resposta dos agentes locais. Possivelmente, a maior distorção do ambiente econômico-financeiro brasileiro seja o nível extremamente alto das taxas de juros de curto prazo, apesar dos avanços estruturais recentes. A disparidade em relação às taxas praticadas em economias desenvolvidas - ou mesmo em comparação a mercados emergentes com níveis similares de risco soberano – cria uma série de disfunções que afetam virtualmente todos os segmentos da economia real. O objetivo desta Tese foi mapear (e utilizar para apreçamento de ativos e derivativos) algumas particularidades de comportamento da ETTJ brasileira, eventualmente não compartilhadas por curvas de outras economias, portanto usando uma abordagem relativamente segregada das principais correntes de pesquisa em modelagem de renda fixa. O trabalho está dividido em duas fases: a primeira exploratória, através da aplicação de técnicas de estatística multivariada, Teoria de Carteiras e instrumentos de avaliação de risco para traçar a evolução histórica da curva de juros brasileira e seus prêmios e preços de risco associados a fatores endógenos e exógenos. A segunda parte da pesquisa faz uso das evidências estatísticas levantadas, incorporando-as a priori em um modelo semiparamétrico de apreçamento de derivativos, combinando elementos básicos de Teoria da Informação. Sua aderência e representatividade foram testadas sobre uma ampla base de opções de futuros de DI, sendo comparadas aos resultados de um modelo tradicional de mercado (BGM). A Tese conclui que a dinâmica da ETTJ brasileira entre 2001 e 2010 deve incorporar no seu processo de modelagem uma perspectiva histórica de percepção de riscos, aproximando a relação entre abordagens clássicas de apreçamento e a prática corrente dos agentes locais. / [en] Modeling the term-structure movements of interest rates is a task that has been attracting a crescent number of researchers and practitioners in quantitative finance, given its importance as the main driver for the economic cost of capital. The volume of traded interest rate sensitive assets and derivatives has grown significantly over the last few years, followed by increasingly complex models of pricing and analysis. The high dimensionality of the object of study requires the use of mathematical tools quite different from standard stock market models, resulting in several approaches that eventually lack a unified framework, flexible enough to capture the dynamics of some particular markets. In Brazil the yield curve analysis is even more complex, due to the fast increase of fixed income products over the last ten years, and the historical shifts in the monetary policy conduction. The risk premium in the Brazilian term-structure of interest rates is partially driven by some specific defensive behavior, following past monetary decisions. Until 2008, the Brazilian Central Bank has primarily dealt with domestic and external crises by raising the short term rate to restrain capital outflows, generating a well-known asymmetry in the market’s response functions to risk aversion. Therefore, the traditional parameterization of risk based on mean and variance estimators fails to capture the market price of risk assigned to higher order moments of bond returns across several maturities. The main purpose of this thesis was to get a broad picture of the singularities of the Brazilian term-structure dynamics, and use it to propose alternative approaches to interest rate derivatives pricing – particularly, embodying the third and fourth (pseudo) moments of bond returns into the modeling cycle. The work is divided in two parts: the first exploratory, applying multivariate statistics, portfolio theory and risk management tools to trace the historical evolution of the Brazilian yield curve, and plot the timeline of risk premia and prices of risk linked to exogenous and endogenous factors. The second part of the research uses the statistical evidence gathered as input to a semi-parametric model for pricing derivatives, based on elements of Information Theory. The model was back-tested over an extensive database of local interest rate options, and compared to the results of a traditional market model (BGM). The thesis concludes that the dynamics of the Brazilian yield curve is in part driven by its historical heritage, and endogenous risk factors including moments of bond returns of third and fourth orders are relevant for the premia structure and evolution. Bringing these elements into a modeling process might partially bridge the gap between classical curve models and the local pricing practice.

Neste artigo, avaliamos o prêmio de risco implícito incorporado nos preços futuros de soja através de um modelo de dois fatore bem conhecido na literatura de commodities. Como os preços da soja na última década têm flutuado muito, primeiro examinamos as quebras estruturais na variância/volatilidade para obter uma proxy para as mudanças nos prêmios de risco. Em seguida, calibramos o modelo de dois fatores em cada subperíodo de toda a série de acordo com as quebras encontradas. Em seqüência, calculamos o prêmio de risco implícito pelo modelo. Constatamos que o prêmio de risco é variável no tempo, não apenas no sinal, mas também na magnitude. Além disso, quando os preços estavam subindo, a posição dominante era dos produtores protegendo-se com um prêmio de risco positivo, enquanto quando os preços estavam caíndo, consumidores se protegiam com um prémio de risco negativo. / In this paper we evaluate the implied risk premium embedded in soybean future prices through a well-known two-factor model in the commodity literature. Since soybean prices in the past decade have fluctuated greatly, we first examine the structural breaks in variance/volatility to obtain a proxy for risk premiums changes. Then we calibrate the two-factor model in each sub-period of the entire series according to the breaks found. In sequence we compute the risk premium implied by the model. We find that the risk premium is time-varying, not only in sign but also in magnitude. Furthermore, when prices were rising prevailing position was of producers hedging with a positive risk premium, while when prices were falling consumers hedged with a negative risk premium.
