Abstract

This paper proposes a model of delegated portfolio management, in which professional fund managers face a value-at-risk (VaR) constraint. We show that the existence of the VaR constraint impairs the optimal risk sharing in both the trading and delegation stages. As a result, the VaR constraint leads household investors to take excessive risk and may cause the prices of fundamentally uncorrelated assets to be correlated.
