Relationship between Quality of Corporate Governance and Corporate Performance in Tehran Stock Exchange

Due to the agency problem, managers may not use company resources to increase shareholdersʹ value. Experts believe that improving corporationsʹ governance is the best way to solve this problem. Corporate governance includes those criteria which increase decentralization of corporate controls and through which the power of managers to trace their own benefits will be reduced and it also improves corporate performance. The purpose of this research proposal is to rate corporate governance of firms and to investigate the effect of that on the corporate performance. To proxy quality of governance, we propose the construction of a governance index (GOV-I) for the companies compounding the sample. This governance index includes 25 different corporate governance criteria. These criteria are grouped into three governance category indices, which are then combined to produce a single overall index. These three categories are transparency, board structure and ownership structure. We collected data from 90 firms in the fiscal year 1385 and tested the hypothesis with regression method. The result shows that there is not a meaningful relationship between quality of governance and corporate performance.
