Whether mandatory disclosure regulation and insider ownership affect a firm’s cost of capital is an important question in financial economics. In our paper, Mandatory Disclosure Quality, Inside Ownership, and Cost of Capital, which was recently made publicly available on SSRN, we examine this question on a large global sample of more than 10,000 firms across 35 countries.
Theory predict that disclosure regulation is negatively related to the cost of capital due to two separate effects: (i) an information effect in which better disclosure improves investors’ prediction of future cash flows, or (ii) a stewardship effect in which better disclosure improves managerial alignment with shareholders and therefore increases expected cash flows. The stewardship effect is not unique to disclosure, but is also present in other governance mechanisms that increase managerial alignment such as inside ownership. As a result, these alternative alignment mechanisms potentially reinforce or substitute for the stewardship effect of disclosure. We test this argument by examining whether inside ownership is negatively associated with the cost of capital and how inside ownership affects the relation between disclosure and the cost of capital.
