Why is it important for companies to adhere to laws that protect the environment and accept responsibility for society and employees? Where is the (economic) benefit? What do these questions have to do with Corporate Governance (CG) and sustainable corporate leadership? Especially the real estate sector struggles with a relatively negative image when compared to other sectors. There are mechanisms that can identify the value added by good Corporate Governance, including econometric studies using regression analyses. The empirical studies have particular advantages in proving the potential benefit of good Corporate Governance. By using large datasets as the starting point, they can measure the real effects that occurred in the market on performance related variables. These and other results clearly demonstrate the positive connection between good Corporate Governance and various key performance indicators.
