Consolidation and efficiency in the U.S. life insurance industry

No 98-18, Working Papers from Federal Reserve Bank of Philadelphia

Abstract: This paper examines the relationship between mergers and acquisitions, efficiency, and scale economies in the U.S. life insurance industry. We estimate cost and revenue efficiency over the period 1988-1995 using data envelopment analysis (DEA). The Malmquist methodology is used to measure changes in efficiency over time. We find that acquired firms achieve greater efficiency gains than firms that have not been involved in mergers or acquisitions. Firms operating with nondecreasing returns to scale and financially vulnerable firms are more likely to be acquisition targets. Overall, mergers and acquisitions in the life insurance industry have had a beneficial effect on efficiency.
