How are corporate disclosures related to the cost of capital? The fundamental role of information asymmetry

Abstract

Purpose

The purpose of this paper is to analyze empirically the fundamental role that information asymmetry plays in the functioning of an efficient capital market as mediator in the relation between corporate disclosures and cost of capital.

Design/methodology/approach

By using a sample of 1,260 international non-financial listed companies in the period 2007-2014.

Findings

The findings suggest that high-quality financial and social disclosures quality reduce the cost of capital, by decreasing information asymmetry. In other words, the authors find evidence of the mediator role of information asymmetry in the relation between corporate disclosures and the cost of capital. These results are also controlled for differences on accounting standards and other institutional factors.

Originality/value

The central assumption is that the demand for corporate disclosures that reduces the information advantages of some investors (who are more informed) arises from agency conflicts and these information differences in turn, determine the cost of capital. This paper is the first attempt to study, jointly, the effects of decreasing information asymmetries by corporate disclosures on the cost of capital in an international setting. In addition, the authors focussed on both financial and social disclosures, creating empirical proxies whose validity for the analysis has been evidenced.
