قياس الكفاءة النسبية لشركات التأمين الجزائرية باستخدام اسلوب التحليل التطويقي للبيانات DEA

Abstract

The study aims to assess the efficiency of insurance companies in Algeria through the measure of relative efficiency in each insurance company. It tries to find out how to measure the efficiency of insurance companies in Algeria using Data Envelopment Analysis? In order to do so, the study dealt in its theoretical section with the definition of insurance companies, the various methods that are used to assess its efficiency, the main models of Data Envelopment Analysis and the alternative models. The practical section of the study was devoted to measure the relative efficiency of 20 insurance companies in Algeria during the year 2015. Data Envelopment Analysis using the Variable Returns to Scale model has been applied both on inputs and outputs. Where inputs are: general costs and investments and outputs are: total investment revenue, compensations and market share. Results show that input oriented VRS has produced an average relative efficiency equal to 87.18%, while output oriented VRS has produced an average relative efficiency equal to 86.52%. Results also show that 9 insurance companies have achieved 100% relative efficiency. In addition, the study has defined the amount of inputs that should be reduced and the amount of outputs that should be realized in order to achieve total efficiency in the remaining companies. Keywords:relative efficiency, Algerian insurance companies, Data Envelopment Analysis, Variable Returns to scale, Constant Returns to scale.
