In this research, managerial ability calculated by usingthe data envelopment analysis (DEA). Following the approach of Faulkender andWang, we find that the relation between managerial ability and value of cash holdingand the level of cash is positive and significant. This result indicates that whenmanagers allocate cash resources efficiently, shareholders consider more value forthe firm cash holding. Also, the result shows that if managers emphasize bothlong-term and short-term of resource management, investors set a higher marginalvalue of cash holdings. In the other words, the able management can improve thevalue of cash holding by the focusing on the spending resource for both long andshort-term periods.

One of the reasons that companies avoid paying their taxes is that they choose to use debts for their funding. In other words, tax saving, an activity of companies to avoid taxpaying, can be used to finance corporate projects. Furthermore, since institutional owners are more inclined to supervise, they may shrink managerial behaviors to avoid taxpaying. In this study, institutional owners’ supervisory role about tax efficiency on corporate capital structure was investigated. For this purpose, a sample of 98 companies from 2005 to 2014 was selected from companies listed on Tehran Stock Exchange (TSE). Following the research conducted by Kramer, multiple linear regression based on panel data and the econometric software Eviews were used for testing the research hypotheses. The results show that tax has a negative and significant impact and institutional ownership has a positive and significant impact on capital structure. In addition, the institutional ownership in corporate companies impacts and adjusts the relationship between tax and capital structure.

The amount of deviation is less than the forecast of higher accuracy. Although there are various methods for predicting but the use of artificial intelligence techniques is increasing due to fewer restriction. The aim of this study is to evaluate the predictive power of profitability using DEA and neutral network, to enhance the decision-making users of 2012 to 2015of 7 premier financial ratios were used as independent variables. Test results show that both of ANN and DEA have ability to forecast profitability and given that neutral network prediction accuracy is higher than the DEA, the model predict better the profitability of companies.
