Títulos de dívida corporativa de empresas brasileiras: investir em emissões do mercado interno ou externo?

O objetivo deste trabalho é analisar a diferença de rentabilidade entre emissões de títulos de dívida corporativa de empresas brasileiras nos mercados local e externo. Sob a ótica do investidor interessado em comprar esses títulos, busca-se responder se, protegendo-se contra oscilações de fatores como câmbio e juros e controlando pelo prazo de vencimento, seria mais rentável em média adquirir um título local (debênture) ou externo (bond) de um mesmo emissor. Para isso, analisamos 177 emissões de debêntures e 119 emissões de bonds de 31 companhias não financeiras brasileiras no período entre janeiro de 2004 e abril de 2013. Regressões em painel com efeitos fixos para controlar pelas características de cada emissor verificam que, em média, o título do mercado externo paga de 164 a 197 bps a mais que o do mercado local, e que tal diferença é estatisticamente significante. A diferença deve-se à maior oferta e variedade de títulos de dívida corporativa no mercado externo, à existência de uma demanda cativa de investidores institucionais por debêntures no mercado local e à falta de integração entre os mercados. A participação de pessoas físicas no mercado externo também é identificada como fator relevante, assim como o possível maior custo de estruturação de dívida cobrado por bancos de investimento no mercado doméstico. Dentre as hipóteses formuladas para o motivo dessa diferença de rentabilidade não ser arbitrada, destacam-se o desconhecimento dos investidores e obstáculos operacionais, como custos de transação, impossibilidade de operação no mercado internacional e de venda a descoberto no mercado local. Tal fato causa ainda uma supervalorização das debêntures pela atuação dos investidores mais otimistas. A alta sensibilidade dos investidores institucionais locais à volatilidade dos retornos, também aparece como fator relevante.

A variação de ativos e retorno das ações no mercado de capitais brasileiro

A literatura de finanças tem encontrado diversas relações entre indicadores financeiros e o retorno de ações. Testamos a relação entre variação dos ativos totais e o retorno das ações para o mercado de capitais brasileiro. Foram realizadas regressões em painéis para testar se esta relação permanece válida mesmo em uma economia emergente como a do Brasil. Comparou-se a capacidade previsora da variação do ativo total com outros indicadores financeiros conhecidos na literatura

Monetary policy and the cross-section of stock returns: a FAVAR approach

We use a factor-augmented vector autoregression (FAVAR) to estimate the impact of monetary policy shocks on the cross-section of stock returns. Our FAVAR combines unobserved factors extracted from a large set of nancial and macroeconomic indicators with the Federal Funds rate. We nd that monetary policy shocks have heterogeneous e ects on the crosssection of stock returns. These e ects are very well explained by the degree of external nance dependence, as well as by other sectoral characteristics.

Previsão da inadimplência bancária no Brasil através dos métodos FAVAR e FAVECM

O objetivo do presente trabalho é utilizar modelos econométricos de séries de tempo para previsão do comportamento da inadimplência agregada utilizando um conjunto amplo de informação, através dos métodos FAVAR (Factor-Augmented Vector Autoregressive) de Bernanke, Boivin e Eliasz (2005) e FAVECM (Factor-augmented Error Correction Models) de Baneerjee e Marcellino (2008). A partir disso, foram construídas previsões fora da amostra de modo a comparar a eficácia de projeção dos modelos contra modelos univariados mais simples - ARIMA - modelo auto-regressivo integrado de média móvel e SARIMA - modelo sazonal auto-regressivo integrado de média móvel. Para avaliação da eficácia preditiva foi utilizada a metodologia MCS (Model Confidence Set) de Hansen, Lunde e James (2011) Essa metodologia permite comparar a superioridade de modelos temporais vis-à-vis a outros modelos.

A stochastic discount factor approach to asset pricing using panel data

Using the Pricing Equation, in a panel-data framework, we construct a novel consistent estimator of the stochastic discount factor (SDF) mimicking portfolio which relies on the fact that its logarithm is the ìcommon featureîin every asset return of the economy. Our estimator is a simple function of asset returns and does not depend on any parametric function representing preferences, making it suitable for testing di§erent preference speciÖcations or investigating intertemporal substitution puzzles.

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 preferences. The techniques discussed in this paper were applied to two relevant issues in macroeconomics and finance: the first asks what type of parametric preference-representation could be validated by asset-return data, and the second asks whether or not our SDF estimator can price returns in an out-of-sample forecasting exercise. In formal testing, we cannot reject standard preference specifications used in the macro/finance literature. Estimates of the relative risk-aversion coefficient are between 1 and 2, and statistically equal to unity. We also show that our SDF proxy can price reasonably well the returns of stocks with a higher capitalization level, whereas it shows some difficulty in pricing stocks with a lower level of capitalization.

Estimating the stochastic discount factor without a utility function

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 serial-correlation ìcommon featureîin every asset return of the economy. Our estimator is a simple function of asset returns, does not depend on any parametric function representing preferences, is suitable for testing di§erent preference speciÖcations or investigating intertemporal substitution puzzles, and can be a basis to construct an estimator of the risk-free rate. For post-war data, our estimator is close to unity most of the time, yielding an average annual real discount rate of 2.46%. In formal testing, we cannot reject standard preference speciÖcations used in the literature and estimates of the relative risk-aversion coe¢ cient are between 1 and 2, and statistically equal to unity. Using our SDF estimator, we found little signs of the equity-premium puzzle for the U.S.

Trade barriers and productivity growth: cross-industry evidence

This article investigates the impact of trade protection on the evolution of labor productivity and total factor productivity (TFP) of the Brazilian manufacturing sector. An annual panel-dataset of 16 industries for the years 1985 through 1997, a period that includes a major trade liberalization, was used. The regressions reported here are robust to openness indicator (nominal tari®s and e®ective protection rate were used), control variables and time period and suggest that barriers to trade negatively a®ects productivity growth at industry level: those sectors with lower barriers experienced higher growth. We were also able to link the observed increase of industry productivity growth after 1991 to the widespread reduction on exective protection experienced in the country in the nineties.

Elasticity of substitution between capital and labor: a panel data approach

This paper estimates the elasticity of substitution of an aggregate production function. The estimating equation is derived from the steady state of a neoclassical growth model. The data comes from the PWT in which different countries face different relative prices of the investment good and exhibit different investment-output ratios. Then, using this variation we estimate the elasticity of substitution. The novelty of our approach is that we use dynamic panel data techniques, which allow us to distinguish between the short and the long run elasticity and handle a host of econometric and substantive issues. In particular we accommodate the possibility that different countries have different total factor productivities and other country specific effects and that such effects are correlated with the regressors. We also accommodate the possibility that the regressors are correlated with the error terms and that shocks to regressors are manifested in future periods. Taking all this into account our estimation resuIts suggest that the Iong run eIasticity of substitution is 0.7, which is Iower than the eIasticity that had been used in previous macro-deveIopment exercises. We show that this lower eIasticity reinforces the power of the neoclassical mo deI to expIain income differences across countries as coming from differential distortions.

Nonparametric tail risk, macroeconomics and stock returns: predictability and risk premia

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.

Consumption-wealth ratio and expected stock returns: evidence from panel data

This paper investigates the role of consumption-wealth ratio on predicting future stock returns through a panel approach. We follow the theoretical framework proposed by Lettau and Ludvigson (2001), in which a model derived from a nonlinear consumer’s budget constraint is used to settle the link between consumption-wealth ratio and stock returns. Using G7’s quarterly aggregate and financial data ranging from the first quarter of 1981 to the first quarter of 2014, we set an unbalanced panel that we use for both estimating the parameters of the cointegrating residual from the shared trend among consumption, asset wealth and labor income, cay, and performing in and out-of-sample forecasting regressions. Due to the panel structure, we propose different methodologies of estimating cay and making forecasts from the one applied by Lettau and Ludvigson (2001). The results indicate that cay is in fact a strong and robust predictor of future stock return at intermediate and long horizons, but presents a poor performance on predicting one or two-quarter-ahead stock returns.
