Does Corporate Governance Matter in Iran?
In this paper, we construct a corporate governance Index (G-index) based on 13 attributes, which are associated with good and bad governance to investigate the impact of corporate governance on a firm’s stock return. After correlating each of the governance attributes of 141 Tehran Stock Exchange li...
