The Effects of Corporate Characteristics on Managerial Entrenchment

The present study aims to assess the relationship between some corporate factors and managerial entrenchment in companies listed on the Tehran Stock Exchange during 2011-2017. Panel data regression models were used to test the hypotheses. The obtained results indicated that four corporate factors, namely real earnings management, predictable earnings management, institutional ownership, and board independence, have a significant relationship with the managerial entrenchment. In this study, the mixed index of managerial entrenchment is calculated using the principal component analysis based on four governance mechanisms of the percentage of shares available to the CEO, CEO duality, CEO compensation logarithm, and CEO tenure. This process has made the present study distinct from the previous ones, in which individual indexes were used for evaluating the entrenchment.
