Is There a Diversification Discount in Financial Conglomerates?

This paper investigates whether the diversity of activities conducted by financial institutions

influences their market valuations. We find that there is a diversification discount: The market

values financial conglomerates that engage in multiple activities, e.g., lending and non-lending

financial services, lower than if those financial conglomerates were broken into financial

intermediaries that specialize in the individual activities. While difficult to identify a single causal

factor, the results are consistent with theories that stress intensified agency problems in

financial conglomerates that engage in multiple activities and indicate that economies of scope are

not sufficiently large to produce a diversification premium.
