A Model of Cross-Section of Equity Returns and Firm Dynamics
نویسنده
چکیده
We put forward a general equilibrium model that links the cross-section variation of expected returns to rmslife cycle dynamics. In the model all assets have the same exposure to short-run consumption risks, but di¤er in their exposure to long-run consumption risks (Bansal and Yaron (2004)). An econometrician who uses conditional CAPM regression to predict asset returns will obtain higher for assets with higher exposure to long-run risks. Growth options have lower exposure to long-run risks than assets in place because the cost of exercising the growth options has high exposure to long-run risks and therefore provides a hedge against the risks of assets place. Small rms have higher exposure to long-run risks because they have higher operating leverage. Please do not distribute in any way without the authorspermission.

Financial Distress and the Cross Section of Equity Returns
In this paper, we provide a new perspective for understanding cross-sectional properties of equity returns. We explicitly introduce financial leverage in a simple equity valuation model and consider the likelihood of a firm defaulting on its debt obligations as well as potential deviations from the absolute priority rule (APR) upon the resolution of financial distress. We show that financial le...
متن کاملUnderstanding the Effect of Advertising on Stock Returns and Firm Value: Theory and Evidence from a Structural Model
T paper brings structural modeling to the literature on financial research in marketing. I propose a dynamic investment-based model to understand the impact of advertising expenditures on stock returns and firm value. In addition, by interpreting advertising expenditures as an investment in brand capital, the approach in this paper provides a novel way to measure brand equity grounded in econom...
متن کاملThe Cross Section of Equity Implied Variance
The implied variances of 167 firms are examined over the period 1991 through 1995. The traditional market model of returns is shown to be a good first order model for explaining the cross section of variances though firm specific variances appear to exhibit stronger covariance than the market model predicts. The existence of a positive bias over realized and forecast variances is documented. Th...
متن کاملThe second moment matters! Cross-sectional dispersion of firm valuations and expected returns ¬リニ
Behavioral theories predict that firm valuation dispersion in the cross-section (‘‘dispersion’’) measures aggregate overpricing caused by investor overconfidence and should be negatively related to expected aggregate returns. This paper develops and tests these hypotheses. Consistent with the model predictions, I find that measures of dispersion are positively related to aggregate valuations, t...
متن کاملCross-Section Unit-Root Tests of The Returns on Equity and Invested Capital: State-Dependent Mixtures of I(1) and I(0) Dynamics in the ROE and ROIC
Cross-section finance studies virtually never test variables for unit roots, though econometric validity depends on testing. This paper develops a cross-section unit-root test and uses it on annual data for the return on equity and the return on invested capital, ROE and ROIC, key variables in the Edwards-BellOhlson (EBO) accounting and Free Cash Flow (FCF) finance valuation models. Conventiona...
