An analysis of efficiency in the delivery of financial services: The case of life insurance agencies

Scale and scope economies are examined for life insurance agencies that distribute multiple financial products. The results of this study suggest that there are significant administrative returns to scale for firms that sell a mix of financial products. The findings for scope estimates are inconsistent, suggesting that there are positive and negative cost complementaries for pairs of products. Subadditivity can be rejected, suggesting that joint distribution of financial products is not necessarily more efficient than specialization and that different-sized agencies are not necessarily at a cost disadvantage.
