ABSTRACT
The purpose of this research is to examine whether insurers have improved their economic performance through efficiency as a reaction to the prolonged period of low interest rates. The results of an analysis of 22 years of data, using a two-stage data envelopment analysis approach (DEA), show that there is an inverse relationship between efficiency and interest rate. The non-life insurance group had a superior level of efficiency compared with that of the life insurance group. It seems that life insurance companies, to some extent, transferred their inefficiency to customers to maintain their solvency. Additionally, this research shows that companies with substantial market power and bancassurance exceeded the performance of the rest of the industry.
