Disclosure frequency and information asymmetry

The main purpose of this paper is to investigate whether more frequent disclosure by firms is associated with lower levels of information asymmetry among investors. Using a panel of 386 firms in the US retail sector, I find that the practice of regularly providing monthly revenue disclosures is not associated with reduced information asymmetry. In contrast, I find that more detailed (greater quantity) disclosure is associated with reduced information asymmetry. I provide preliminary evidence that the distinction between disclosure frequency and disclosure quantity is due to more frequent disclosure providing an incentive for increased private information acquisition by sophisticated investors. The results indicate that the relation between disclosure and information asymmetry is multi-dimensional and varies depending on the disclosure attribute being studied.
