Essays on Asset Pricing and Econometrics

Jin, Tao 06 June 2014 (has links)
This dissertation presents three essays on asset pricing and econometrics. The first chapter identifies rare events and long-run risks simultaneously from a rich data set (the Barro-Ursua macroeconomic data set) and evaluates their contributions to asset pricing in a unified framework. The proposed model of rare events and long-run risks is estimated using a Bayesian Markov-chain Monte-Carlo method, and the estimates for the disaster process are closer to the data than those in the previous studies. Major evaluation results in asset pricing include: (1) for the unleveraged annual equity premium, the predicted values are 4.8%, 4.2%, and 1.0%, respectively; (2) for the Sharpe ratio, the values are 0.72, 0.66, and 0.15, respectively. / Economics

No. of bitstreams: 1 Tese - Versao final - Diego Brandao.pdf: 1402061 bytes, checksum: 2a9d03af25fdeae9cb4300343d707aa2 (MD5) Previous issue date: 2016-09-23 / The thesis consists in three articles about the estimation of asset pricing models. The first paper analyses small sample properties of Generalized Empirical Likelihood estimators for the risk aversion parameter in CRRA preferences when the economy is characterized by rare disasters. In the second article, we develop and test a methodology to assess misspeci fied asset pricing models by taking into account the smallest probability distortion necessary to assign correct prices. In the final paper, we estimate an approximate long run risks model using Brazilian data. / Esta tese consiste em três artigos sobre a estimação de modelos de apreçamento de ativos. No primeiro artigo, analisamos as propriedades de amostra pequena dos estimadores da classe Generalized Empirical Likelihood para o coeficiente de aversão ao risco de preferências CRRA quando a economia é suscetível a desastres. No segundo artigo, apresentamos e testamos uma metodologia de avaliação de modelos de apreçamento mal especificados que leva em conta a menor distorção de probabilidade necessária sobre a medida real para que modelo aprece corretamente ativos. No terceiro artigo, estimamos uma versão aproximada do modelo de riscos de longo prazo utilizando dados brasileiros.

[en] DOES THE STOCK MARKET REFLECT THE LONG-RUN EFFECTS OF COVID-19? / [pt] O MERCADO ACIONÁRIO REFLETE OS EFEITOS DE LONGO PRAZO DA COVID-19?

RAFAEL PEREIRA ALVES 28 June 2022 (has links)
[pt] A literatura existente sobre os efeitos da Covid nos retornos das ações concentra-se em mudanças endógenas na tolerância ao risco e na modelagem de eventos raros. Até agora, essas tentativas não foram capazes de corresponder aos dados. Neste artigo, proponho uma abordagem alternativa para explicar os efeitos da Covid nos retornos de ativos em todo o mundo: separar os efeitos de longo prazo dos efeitos de curto prazo. Intuitivamente, os efeitos de longo prazo da Covid incluem disrupções nas cadeias produtivas e padrões educacionais, que, concebivelmente, levarão tempo para serem eliminados. Exatamente como acontece com os choques persistentes dos modelos de risco de longo prazo! Um modelo que permite flutuações de curto prazo e risco de longo prazo mostra que choques persistentes desempenham um papel na explicação dos retornos do mercado de ações e das taxas de câmbio em um período de tempo que começa em Janeiro de 2018 e termina em Novembro de 2021. / [en] The existing literature on the effects of Covid on stock returns focuses on endogenous changes in risk tolerance and on the modeling of rare events. So far, these attempts have not been able to match the data. In this paper, I propose an alternative approach to explaining the Covid effects on stock returns worldwide: disentangling the long-run effects from the short-run effects. Intuitively, Covid s long-run effects include disruptions of supply chains and educational patterns, which, conceivably, will take time to phase out. Exactly as it happens with the persistent shocks of long-run risks models! A model that allows for short-run fluctuations and long-run risk shows that persistent shocks play a role in explaining stock market returns and exchange rates in a time span that starts in January 2018 and ends in November 2021.
