Modeling Conditional Skewness in Stock Returns [PDF]
In this paper we propose a new GARCH-in-Mean (GARCH-M) model allowing for conditional skewness. The model is based on the so-called z distribution capable of modeling moderate skewness and kurtosis typically encountered in stock return series.

Autorregresive conditional volatility, skewness and kurtosis [PDF]
This paper proposes a GARCH-type model allowing for time-varying volatility, skewness and kurtosis. The model is estimated assuming a Gram-Charlier series expansion of the normal density function for the error term, which is easier to estimate than the ...

Mean-Variance-Skewness Portfolio Performance Gauging: A General Shortage Function and Dual Approach [PDF]
This paper proposes a nonparametric efficiency measurement approach for the static portfolio selection problem in mean-variance-skewness space. A shortage function is defined that looks for possible increases in return and skewness and decreases in ...
