The purpose of this study is to investigate the factors affecting the evaluation of the quality of voluntary disclosure, given that the factors used in internal research due to having an external source and focusing on the number of disclosures may not be an appropriate criterion for measuring the quality of information disclosure, so, it is necessary to provide new influencing factors on the e...

Many organizational and environmental factors affect the information disclosure and the quality of its presentation; organizational culture is the most important factor among these factors. The organizational culture that is based on transparency will provide the information environment dynamism and it will also lead to the improvement of the quality of information disclosure by the business un...

Competition creates strategic incentives for firms to communicate private information about product quality through signalling rather than voluntary disclosure.

A high-quality firm may not discl...

I examine Health Maintenance Organizations' (HMOs) voluntary disclosure of product quality, which is not as complete as unraveling theories predict. After controlling for cost and demand factors, I find that HMOs use voluntary disclosure to differentiate from competitors, with lower disclosure rates in highly competitive markets. These findings are consistent with product differentiation, but c...

Firms subject to greater litigation risk disclose more risk factors, update the language more from year-to-year, and use more readable language than firms with low...

Ball and Shivakumar (2008) suggest mandatory periodic reporting disciplines disclosure and encourages timely voluntary disclosure. We examine this hypothesis using the shock to reporting quality experienced by former Arthur Andersen clients after they were forced to switch auditors. Consistent with the confirmatory role of mandatory reporting, we find that former Andersen clients increase discl...
