I explore an intricate interaction between a firm’s risk exposure, intangible capital accumulation, and physical capital accumulation by using a unified dynamic investment model of capital allocation. The model emphasizes both the importance of the marginal value of the intangible capital and...

We test whether the country risk variable is a significant risk factor in several CAPM based models of expected equity returns in Argentina, Brazil, Mexico, South Africa, Russia, Turkey and Venezuela. We also test the usual assumption that country risk can be added with a coefficient value of...

While existing asset pricing studies focus on macroeconomic variables to predict stock market risk premium, we find that an aggregate index of corporate activities has substantially greater predictive power both in- and out-of sample, and yields much greater economic gain for a mean-variance...

The Equity risk-premium and volatility puzzle - is it possible to have a high equity premium and a low risk-free rate with a plausible risk aversion- have received a great deal of attention but beyond this question, the fundamental issues of that puzzle are the followings: what are the economic...

The Equity risk-premium and volatility puzzles: Is it possible to have a high-equity premium and a low risk-free rate, and a high volatile stock return, have received a great deal of attention but beyond this, the fundamental issues are the following: What are the economic representations that...

This paper develops a tractable asset pricing framework based on an Arrow Debreu economy with heterogeneous agents. The assumption of heterogeneity recasts the market rather than aggregate consumption as the key element for pricing securities. The model expresses some asset pricing relationships...

We develop a dynamic equilibrium model to derive testable time-series and cross-sectional implications for the endogenous relations among ownership concentration, managerial incentives, and asset prices. For a given firm at any date, ownership concentration is positively related to managerial...

Anomalies are empirical results that seem to be inconsistent with maintained theories of asset-pricing behavior. They indicate either market inefficiency (profit opportunities) or inadequacies in the underlying asset-pricing model. After they are documented and analyzed in the academic...

This paper examines to what extent stock market anomalies are driven by firm fundamentals in an investment-based asset pricing framework. Using Bayesian Markov Chain Monte Carlo (MCMC), we estimate a two-capital q-model to match firm-level stock returns, instead of matching portfolio-level...

A detailed treatment of aggregation and capital heterogeneity substantially improves the performance of the investment CAPM. Firm-level predicted returns are constructed from firm-level accounting variables and aggregated to the portfolio level to match with portfolio-level stock returns....
