Corporate governance involves the relationships between a company's management, board, shareholders, and other stakeholders. It provides the structure for setting objectives, monitoring performance, and accountability. Good corporate governance should incentivize pursuing shareholder interests and efficient use of resources. Key elements include defining relationships through ownership structures and processes, balancing differing interests, and distributing rights and responsibilities to increase long-term shareholder value. Benefits include improved performance, access to capital, lower costs of capital, and reputation. Mechanisms include boards of directors, large shareholders, market forces, and monetary incentives for managers.
