Abstract
In recent years, estimating the efficiency and ranking of firms in different sectors of the industry, has been one of the most important and the most practical tools for managers and politicians to make critical decisions. Different models have been employed to estimate the efficiency of units, one of the most important of them is the data envelopment analysis method. In researches that the data envelopment analysis method is used, the environmental variables, which have affected the achieved efficiency scores, are identified and estimated in a two- stage method. The present study, with using the two-stage method was conducted to estimate the efficiency of 25 insurance companies which were active in the Iranian insurance market (between the years 2009-2015). During the first stage, data envelopment analysis and then Bootstrap method were used in order to modify the obtained efficiency scores. The data envelopment analysis method has no statistical support; therefore, it is possible that with changing the sample size, the efficiency scores and ranking of companies change accordingly. Thus, to overcome this problem, the bootstrap method was used to determine the performance of companies in terms of their efficiency and ranking with high certainty. Further on the research, the second stage dealt with the analysis of the effect of the identified environmental variables (including 8 variables) on the efficiency of the insurance companies by using the econometric method (panel data). Innovation of The present study is considering the effect of the bancassurance variable on the efficiency of insurance companies, because based on the carried out researches, the previous studies merely considered the impact of the bancassurance variable on the efficiency of banks. What is worth mentioning is studying the impact of these channels on the efficiency from the insurance point of view; and the final result is exclusively about insurance companies and does not include the banks. The findings of this research show that there is a meaningful reverse relationship between the bancassurance channel and the efficiency of the Iranian insurance companies.
