An Analysis of the Relative Efficiencies of Insurance Companies In Nigeria, 2001-2005
用数据包络分析法衡量尼日利亚商业保险公司的相对效率，发现最有效率的公司既不是最大也不是最老的，且部分公司在规模效率上表现不佳。
Although there exists some rating agencies which benchmark the performance of the banking industry in Nigeria such agencies are not available in the insurance industry thereby making a choice among the insurance companies a difficult one. This study uses Data Envelopment Analysis to determine the relative efficiencies of commercial insurance companies in Nigeria. The study reveals that not all the companies were effi-cient with respect to Scale Efficiency and that contrary to what might have been ex-pected, the most efficient insurance company is neither the biggest nor the oldest. Keywords: Nigerian Insurance Companies, Data Envelopment Analysis, Performance, Tech-nical Efficiency, Scale Efficiency, Benchmarking.
