Risk Aversion and Optimal Portfolio Policies in Partial and General Equilibrium Economies

Risk Aversion and Optimal Portfolio Policies in Partial and General Equilibrium Economies∗

In this article, we show how to analyze analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio constraints. The exact local comparative statics and approximate but analytical expression for the portfolio ...

Optimal Portfolio Policies under Bounded Expected Loss and Partial Information Optimal Portfolio Policies under Bounded Expected Loss and Partial Information *

In a market with partial information we consider the optimal selection of portfolios for utility maximizing investors under joint budget and shortfall risk constraints. The shortfall risk is measured in terms of expected loss. Stock returns satisfy a stochastic differential equation. Under general conditions on the corresponding drift process we provide the optimal trading strategy using Mallia...

Optimal portfolio policies under bounded expected loss and partial information

In a market with partial information we consider the optimal selection of portfolios for utility maximizing investors under joint budget and shortfall risk constraints. The shortfall risk is measured in terms of expected loss. Stock returns satisfy a stochastic differential equation. Under general conditions on the corresponding drift process we provide the optimal trading strategy using Mallia...

Dynamic value at risk under optimal and suboptimal portfolio policies

At present, all value at risk (VaR) implementations ± i.e., all risk measures of thè`maximum loss at a given level of con®dence'' type ± are based on the assumption that the portfolio mix will not change before the VaR horizon. This hypothesis may be unrealistic, especially when the VaR horizon is established by the regulators (BIS). At the opposite, we measure VaR dynamically, i.e., taking int...
