| Abstract: | Abstract: The aim of this paper is to estimate the productivity change of Nigerian insurance companies and to rank the companies analysed in the sample according to their productivity score. This benchmark exercise provides the companies analysed with a view of how their relative productivity can be upgraded. For this purpose, the non‐parametric Luenberger productivity model is used. For comparative purposes, the non‐parametric Luenberger–Hicks–Moorsteen productivity indicator is also used. The companies are ranked according to their total productivity for the period 1994–2005, using both models, which produce variations in the respective results. Economic implications arising from the study are derived. |
