Abstract: This paper establishes the Mean-VaR model based on the well-known Mean-Variance asset allocation framework by replacing variance with VaR.By using the IsoVaR,the relations between Mean-VaR model and Mean-Variance model are analyzed.Furthermore,the cases with a riskless security,liability and non-normality are considered respectively.Finally,economic interpretations of some results in this paper are proposed.

Key words: Mean-Variance model, VaR, Mean-VaR model, IsoVaR, efficient frontier
