This paper investigates whether the business press serves as an information intermediary. The press potentially shapes firms' information environments by packaging and disseminating information, as well as by creating new information through journalism activities. We find that greater press...

This study examines short selling in stocks of firms that reveal partial earnings-related information prior to their eventual earnings announcements (EA). By decomposing short selling into two components where the first corresponds to the final partial earnings disclosure and the second captures...

We propose and estimate a model of endogenous informed trading that is a hybrid of the PIN and Kyle models. When an informed trader trades optimally, both returns and order flows are needed to identify information asymmetry parameters. Empirical relationships between parameter estimates and...

We empirically examine the joint predictions of the pecking order theory and the theory of time-varying asymmetric information regarding the timing of security offerings around information disclosures. We analyze loan originations and bond offerings around earnings announcements and compare them...

Financial markets and macroeconomic environments are often characterized by positive externalities. In these environments, transparency may reduce expected welfare from an ex-ante point of view: public announcements serve as a focal point for higher-order beliefs and affect agents' behaviour...

This paper is an empirical investigation of how traders react to public news in a market where there are lots of non-scheduled announcements, often arriving simultaneously. Using detailed trade information from the Nordic intra-day electricity market and GARCH models, this paper examines market...

Hard-to-value stocks provide opportunities for managers to exploit their informational advantage through trading on their firms' and their own personal accounts. In contrast to the prediction that such transactions reflect private information about future events, they are contrarian and heavily...
