Abstract

We consider an optimal portfolio diversification model in which a large shareholder can influence shares return by monitoring efficiently managers. Less diversification decreases insurance but increases the stake in the ownership and then enhances efficiency of management monitoring. We analyze the effect of legal shareholders protection on portfolio diversification.
