Application of the two-stage DEA model for evaluating the efficiency and investigating the relationship between managerial ability and firm performance

The aim of this study is to investigate the relationship between managerial ability and firm performance. First, we introduce a new two-stage DEA model with a fuzzy multi-objective programming approach for evaluating the performance of companies listed on the Tehran Stock Exchange. In this regard, the stable operation of companies, into two sub-process, have divided, which includes the profitability (first phase) and the value, creativity (the second phase), that is, the outputs of the first stage are inputs for the second stage, which can be used to identify the status of the company's operations and potential for future growth. Second, In order to measure the ability of managers, we use the model provided by Demerging. Finally, the relationship between managerial ability and firm performance are also investigated by means of the truncated-regression model. The results show that there is a positive relationship between the ability of management and firm performance. It means that managerial ability to be significantly related to the performance of the company. In this sense, the performance of the company improves by increasing managerial ability to better use resources and consequently increase overall efficiency.
