The purpose of this article is to evaluate optimal expected utility risk measures (OEU) in a risk- constrained … constraint to a portfolio selection model using value at risk as constraint. The former is a coherent risk measure for utility … functions with constant relative risk aversion and allows individual specifications to the investor's risk attitude and time …

We revisit mean-risk portfolio selection in a one-period financial market where risk is quantified by a positively … homogeneous risk measure ρ on L1. We first show that under mild assumptions, the set of optimal portfolios for a fixed return is … as the worst-case risk measure.After providing a primal characterization, we focus our attention on coherent risk …

In exploring the extension of the Value-at-Risk approach from applications to investments in financial assets to … applications to investments in real assets, the properties of Value-at-Risk as a risk measure are reviewed. Recognizing that Value-at-Risk …
