Cross-ownership and portfolio choice

Cross-ownership smooths firms' idiosyncratic shocks but affects their portfolio choice and, therefore, their risk-taking position.

However, when the ownership of some firms is concentrated in the hands of a few others, deeper integration leads to excessive risk-taking and volatility and, consequently, it results in lower aggregate welfare.
