No. of bitstreams: 0 Previous issue date: 29 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O propósito desta dissertação foi verificar se o Modelo de Precificação de Ativos de Capital baseado no Consumo (CCAPM) é consistente com os dados de quatro países latino-americanos: Brasil, Chile, Colômbia e México. Para alcançar este objetivo foi realizada uma regressão cross-sectional dos prêmios de risco médios sobre os betas de consumo de cada ativo em cada país analisado. Adicionalmente, de forma análoga a Lintner (1965) e Levy (1978), foi verificado se a variável ‘variâncias residuais’ mostrava-se estatisticamente significante nas regressões cross-sectional, o que seria inconsistente com o modelo. Os resultados empíricos, baseados em estimativas corrigidas para o problema dos erros nas variáveis, demonstram que há uma relação estatisticamente significativa entre os prêmios de risco médios e os betas de consumo nos países acima mencionados, com exceção do México. Apesar disto, o poder explicativo do modelo, dado pelo coeficiente de determinação R2 ajustado, foi muito baixo em todos os países. Quanto à v / The purpose of this thesis is to verify whether the Consumption based Capital Asset Pricing Model (CCAPM) is consistent with the data from four Latin-American countries: Brazil, Chile, Colombia, and Mexico. In order to reach this goal, a cross-sectional regression of the consumption betas on the mean excess returns of each asset is performed for each country analyzed. Also, similar to the studies of Lintner (1965) and Levy (1978), it is verified whether the variable ‘residual variance’ has statistical significance in the cross-sectional regressions, which would be inconsistent with the model. Empirical results showed that there is a statistical significant relationship between mean excess returns and consumption betas in the countries cited above, with exception of Mexico. Despite this, the explanatory power of the model, given by the adjusted coefficient of determination (R2), is very small in all countries. Concerning the variable ‘residual variance’, it is statistically significant for the Brazilian and Me

No. of bitstreams: 1 Tail Risk - Original.pdf: 817189 bytes, checksum: 02561a6a7cb94d1480a4f78933486df4 (MD5) Previous issue date: 2015-02-12 / This paper proposes a new novel to calculate tail risks incorporating risk-neutral information without dependence on options data. Proceeding via a non parametric approach we derive a stochastic discount factor that correctly price a chosen panel of stocks returns. With the assumption that states probabilities are homogeneous we back out the risk neutral distribution and calculate five primitive tail risk measures, all extracted from this risk neutral probability. The final measure is than set as the first principal component of the preliminary measures. Using six Fama-French size and book to market portfolios to calculate our tail risk, we find that it has significant predictive power when forecasting market returns one month ahead, aggregate U.S. consumption and GDP one quarter ahead and also macroeconomic activity indexes. Conditional Fama-Macbeth two-pass cross-sectional regressions reveal that our factor present a positive risk premium when controlling for traditional factors.
