Equity issues and temporal variation in information asymmetry

We investigate the intertemporal relation between information asymmetry and equity issues, and particularly focus on which firms drive this relation. We find that when information asymmetry for a particular firm is low compared to the recent past, the firm is more likely to issue equity as opposed to debt. Importantly, this intertemporal association is driven by firms with high levels of information asymmetry. These firms are more prone to adverse selection costs and thus have more to gain by issuing equity after a narrowing of the information gap between managers and investors. Our findings are robust to various firm-specific proxies for information asymmetry.
