A number of articles have documented that the classical event study methodology exhibits a bias toward detecting quot;effects,quot; irrespective of whether such effects actually exist. This paper addresses this bias by presenting a new methodology that explicitly incorporates stochastic...

This paper addresses this bias by presenting a new methodology that explicitly incorporates stochastic behaviors of the...

This article examines the relationship between risk, return, skewness, and utility-based preferences. Examples are constructed showing that, for any commonly used utility function, it is possible to have two continuous unimodal random variables X and Y with positive and equal means, X having a...

This paper shows that a flaw exists in the logic behind the previously stated theoretical connections between utility theory and moment preferences. In fact, no such relationship exists. There is also a flaw in the logic that postulates that approximate normality can justify moment (e.g.,...
