Attributes of social and human capital disclosure and information asymmetry between managers and investors

Abstract We extend the literature on voluntary disclosure by investigating the impact of precision attribute of social and human capital disclosure on information asymmetry. We provide evidence on how the stock market reacts to different levels of information precision. Overall, results suggest that quantitative disclosure reduces share price volatility and increases Tobin's Q. As expected, firm size attenuates the impact of precision attribute of disclosure on information asymmetry. Furthermore, it appears that firms take into account ultimate costs and benefits to shareholders when determining precision attribute of their disclosure. Finally, our results suggest that efficient governance leads to more disclosure. Copyright © 2009 ASAC. Published by John Wiley & Sons, Ltd.
