Abstract

We show that the diversification of risks at financial institutions has unwelcome effects by increasing the likelihood of systems crises.As a result, complete diversification is not warranted adn the optimal degree of diversification is arbitrarily low.We also identify externalities that cause financial institutions to diversify beyond diversification may thus have reduced welfare.
