August 2009Asset Return Dynamics under Bad Environment Good Environment Fundamentals
with Geert Bekaert: w15222
We introduce a "bad environment-good environment" technology for consumption growth in a consumption- based asset pricing model. Using the preference structure from Campbell and Cochrane (1999), the model generates realistic time-varying volatility, skewness and kurtosis in fundamentals while still permitting closed-form solutions for asset prices. The model not only fits standard salient asset prices features including means and volatilities for equity returns and risk free rates, but also generates a realistic variance premium and option prices.
June 2009Inflation and the Stock Market:Understanding the "Fed Model"
with Geert Bekaert: w15024
The Fed model postulates that the dividend or earnings yield on stocks should equal the yield on nominal Treasury bonds, or at least that the two should be highly correlated. In US data, there is indeed a strikingly high time series correlation between the yield on nominal bonds and the dividend yield on equities. This positive correlation is often attributed to the fact that both bond and equity yields commove strongly and positively with expected inflation. While inflation commoves with nominal bond yields for well-known reasons, the positive correlation between expected inflation and equity yields has long puzzled economists. We show that the effect is consistent with modern asset pricing theory incorporating uncertainty about real growth prospects and habit -- based risk version. In ...


May 2006Stock and Bond Returns with Moody Investors
with Geert Bekaert, Steven R. Grenadier: w12247
We present a tractable, linear model for the simultaneous pricing of stock and bond returns that incorporates stochastic risk aversion. In this model, analytic solutions for endogenous stock and bond prices and returns are readily calculated. After estimating the parameters of the model by the general method of moments, we investigate a series of classic puzzles of the empirical asset pricing literature. In particular, our model is shown to jointly accommodate the mean and volatility of equity and long term bond risk premia as well as salient features of the nominal short rate, the dividend yield, and the term spread. Also, the model matches the evidence for predictability of excess stock and bond returns. However, the stock-bond return correlation implied by the model is somewhat higher t...

Risk, Uncertainty and Asset Prices
with Geert Bekaert, Yuhang Xing: w12248
We identify the relative importance of changes in the conditional variance of fundamentals (which we call %u201Cuncertainty%u201D) and changes in risk aversion (%u201Crisk%u201D for short) in the determination of the term structure, equity prices and risk premiums. Theoretically, we introduce persistent time-varying uncertainty about the fundamentals in an external habit model. The model matches the dynamics of dividend and consumption growth, including their volatility dynamics and many salient asset market phenomena. While the variation in dividend yields and the equity risk premium is primarily driven by risk, uncertainty plays a large role in the term structure and is the driver of counter-cyclical volatility of asset returns.
