This paper examines whether common ownership – i.e., instances where investors simultaneously own significant stakes in competing firms – affects voluntary disclosure. We argue that common ownership (i) reduces proprietary cost concerns of disclosure, and (ii) incentivizes firms to “internalize” the externality benefits of their disclosure for co-owned peer firms. Accordingly, we find a positive relation between common ownership and disclosure. Evidence from cross-sectional tests and a quasi-natural experiment based on financial institution mergers help mitigate concerns that our results are explained by an omitted variable bias or reverse causality. Finally, we find that common ownership is associated with increased market liquidity.

Using a set of proprietary records, we examine who consumes quarterly earnings conference calls and under which circumstances the calls are consumed. While there is significant interest in calls by institutional investors and sell-side analysts, we find that investors who do not hold a position in the firm are a leading consumer. We show that buy-side non-holders who consume calls are more likely to hold positions in competitors and to purchase the stock in the future. In addition, many investors who hold large positions only consume calls periodically. We also document a benefit of consuming calls by finding that the consumption of calls is associated with more informed trading decisions. Overall, our investigation illuminates the actual consumption of conference calls by different consumers and the potential benefits of consuming additional firm disclosures.
