Meta‐analytic review of disclosure level and cost of equity capital

Abstract

Purpose

The purpose of this paper is to meta‐analyze the results of 22 empirical studies that examine the relationship between voluntary disclosure and cost of equity capital. The authors examine whether differences in results are attributable to moderating effects related to disclosure environment, the measurement of the disclosure score and the proxy used to measure the cost of equity capital.

Design/methodology/approach

The approach used is the meta‐analysis statistic technique developed by Hunter et al.

Findings

The results emphasize the need to explicitly consider the legal and institutional aspects (high disclosure environment versus low disclosure environment) when one analyzes the association between disclosure level and cost of equity capital.

Originality/value

Since the authors' analysis confirms the negative association between disclosure and cost of equity capital in countries characterized by low disclosure environment, managers in these contexts are encouraged to make more voluntary disclosure in order to reduce uncertainty among investors and increase the marketability of their securities.
