We report strong evidence that changes of momentum, i.e. "acceleration", defined as the first difference of successive returns, provide better performance and higher explanatory power than momentum. The corresponding Γ-factor explains the momentum-sorted portfolios entirely but not the reverse....

This paper studies the effect of new fund flows on investment behavior and the resulting equilibrium price of risk. The Small Fund Industry model shows equilibria with overinvestment in unprofitable and underinvestment in profitable investment opportunities. The Large Fund Industry model derives...

In this paper, we construct an information asymmetry factor (ECINF) based on the price discovery of large trades. ECINF is significantly negatively correlated with market excess return, indicating that market-wide information asymmetry is lower in bull markets, which is consistent with the view...

We find individuals are four times more likely to purchase stocks of their local direct utility company as opposed to utility companies operating outside their state of residence. Our tests reveal that individuals do not possess superior or private information about their local utilities....

We structurally estimate a model in which agents' information processing biases can cause predictability in firms' asset returns and investment inefficiencies. We generalize the neoclassical investment model by allowing for two biases -- overconfidence and over-extrapolation of trends -- that...

We study general equilibrium in a Lucas (1978) economy with one consumption good and two investors with heterogeneous risk aversions and beliefs about aggregate consumption growth rate, and portfolio constraints. We provide a comprehensive comparison of various constraints, and show which of...

Prior research has found that investors have strong preferences for stocks with positive skewness. These preferences have been shown to lead to price premiums and subsequent underperformance. This study extends this growing body of literature by testing whether the underperformance of stocks...
