內(nèi)容介紹：
One of managers’ concerns is how to enhance their disclosure credibility, especially for qualitative positive disclosures. This study examines two credibility-enhancing strategies when managers use Twitter as a disclosure platform. The first strategy is that managers may retweet a corporate disclosure Tweet in his/her personal Twitter account (hereafter, retweeting). I propose that retweeting increases disclosure credibility since it establishes a closer association between the manager and the message (therefore higher disclosure credibility) than non-retweeting. The second strategy is to mention the involved parties in the corporate disclosure Tweet when the corporate disclosure involves other parties, given that the other parties have verified Twitter accounts (hereafter, mentioning). Mentioning increases social presence of the involved parties since the mentioned party receives real-time notifications about the Tweet in his/her Mentions tab and other users can observe the interactions between the disclosing corporate and the mentioned party on a real-time basis. I predict that higher social presence of the involved party when mentioning (than non-mentioning) increases disclosure credibility. I do not expect retweeting and mentioning interact with each other and I predict their effects to be addictive but not substitutive. This study contributes to our understanding of how some Twitter functions influence the credibility of corporate disclosures and provides important implications for preparers and users of disclosures.
