3. Coordenação de Prazos e Eficiência Previdenciária
Resumo A análise de estilo proposta por Sharpe (1992) dos 457 fundos previdenciários de renda fixa existentes no Brasil entre 2011 e 2015 não deixa dúvida: as alocações financeiras na previdência têm se concentrado em títulos de curtíssimo prazo. Há portanto espaço para o alongamento do prazo médio do sistema, o que elevaria a sustentabilidade e

5. Portfolio optimization using Mean Absolute Deviation (MAD) and Conditional Value-at-Risk (CVaR)
Abstract This paper investigates the efficiency of traditional portfolio optimization models when the returns of financial assets are highly volatile, e.g., in financial crises periods. We also develop alternative optimization models that combine the mean absolute deviation (MAD) and the conditional value at risk (CVaR), attempting to mitigate inefficient, l

6. Corporate sustainability and asset pricing models: empirical evidence for the Brazilian stock market
Abstract The paper investigates the impact of corporate sustainability on asset prices. For that purpose, we develop a novel corporate sustainability factor and test the extent to which this factor is priced in an augmented four-factor version of the traditional Fama & French (1993) asset pricing model. The corporate sustainability factor is based on a zero-

7. The Forward- and the Equity-Premium Puzzles: Two Symptoms of the Same Illness?
Using information on US domestic financial data only, we build a stochastic discount factor—SDF— and check whether it accounts for foreign markets stylized facts that escape consumption based models. By interpreting our SDF as the projection of a pricing kernel from a fully specified model in the space of returns, our results indicate that a model that a

8. Constructing Common-Factor Portfolios
In this paper we construct common-factor portfolios using a novel linear transformation of standard factor models extracted from large data sets of asset returns. The simple transformation proposed here keeps the basic properties of the usual factor transformations, although some new interesting properties are further attached to them. Some theoretical advan

9. A Stochastic discount factor approach to asset pricing using panel data asymptotics
Using the Pricing Equation in a panel-data framework, we construct a novel consistent estimator of the stochastic discount factor (SDF) which relies on the fact that its logarithm is the "common feature" in every asset return of the economy. Our estimator is a simple function of asset returns and does not depend on any parametric function representing prefer

10. GENETIC-NEURAL MODEL FOR PORTFOLIO OPTIMIZATION WITH FINANCIAL OPTIONS IN THE BRAZILIAN MARKET / MODELO GENÉTICO-NEURAL PARA OTIMIZAÇÃO DE CARTEIRAS COM OPÇÕES FINANCEIRAS NO MERCADO BRASILEIRO
This dissertation develops an intelligent, quantitative and probabilistic model to determine an optimal composition of a portfolio consisting of a financial asset and options over this asset. Initially we studied the characteristics of the historical distribution of returns and volatility of the most liquid stocks from the BOVESPA Stock Exchange, from Januar

12. The Aiyagari model with liquidity shoch
A version of the Aiyagari (1994) model with a liquidity shock is developed in this work. The model has Huggett (1993) and Aiyagari (1994) as particular cases, but the general one allows for two assets in the economy, a liquid and an illiquid one. Using two di erent assets implies in two returns clearing the market, so the computational strategy used by Aiyag
