Аннотация:Efficiency measurement is an indispensable matter for any economic establishment, especially insurance companies that operate in a competitive atmosphere and in light of a significant development in the quality and conditions of insurance coverages.Although many studies have dealt with measuring efficiency in insurance companies, those studies used traditional Data Envelopment Analysis models which ignore the sequence and impact of technical processes on the efficiency of these companies.Therefore, the interest of this study was focused on measuring the efficiency of some technical operations carried out by insurance companies, which are production, underwriting and investment.A two-stage Data Envelopment Analysis method has been applied alongside traditional models to achieve the objective of the study, and Wilkoxen and Friedman' s nonparametric tests were used to test the study' s hypotheses.The results showed that the overall efficiency of Saudi insurance companies during the study period using the two-stage model is less than their counterpart using the traditional model and that this difference was statistically significant, as well as the efficiency of underwriting and investment was less than the efficiency of production or marketing and that this difference was statistically significant whether using traditional or two-stage model.The most important recommendations of the study were the need for insurance companies to measure the efficiency of all its technical operations separately and for different types of insurance and at the level of the company' s branches, as well as to periodically review and update underwriting and pricing conditions and study the reasons for the deficit of insurance surplus and work to raising the efficiency of investment.
