The Continuous Testing of Efficient Structure and Quiet-Life Hypotheses in Tehran Stock Exchange: Emphasizing the Role of Human Capital and Management Optimism
Author(s):
Abstract:
This study tests the efficient structure hypothesis and the role of human capital efficiency in predicted relations in this hypothesis as well as the quiet life hypothesis and the role of management optimism in predicted relations in this hypothesis. For this purpose, the data from 136 companies listed in Tehran Stock Exchange during 2010 to 2014, linear regression, and panel data models were used. The results showed that an increase in industry concentration, and in other words, a decrease in industry competition, will improve firms efficiency index (disapproving the quiet life hypothesis in Irans Capital Market) and increasing human capital efficiency, in addition to enhancing the direct relationship between industry concentration and firms efficiency, improves firms efficiency (confirming the role of human capital efficiency in the relationship between industry competition and firms efficiency). Moreover, the firms efficiency will increase firms growth (confirming efficient structure hypothesis in Irans Capital Market) and management optimism, in addition to increasing firms growth, would enhance the direct relationship between efficiency and firms growth (confirming the role of management optimism in efficient structure hypothesis).
