Discretionary accruals are positively associated with stock returns at the aggregate level but negatively so in the cross section. Using Baker-Wurgler investor sentiment index, we find that a significant presence of sentiment-driven investors is important in accounting for both patterns. We...

In this paper we survey the theoretical and empirical literatures on market liquidity. We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how...

This study tests whether disclosing a trader's identity dampens or stimulates subsequent trading volume based on the trader's reputation for being informed. While a reputation for being informed makes markets less liquid, thus inhibiting subsequent trade ("illiquidity effect"), the information...

We investigate if originating banks increase the complexity of European Mortgage Backed Securities (MBS) to obfuscate low securitization quality. When measuring securitization complexity with traditionally used proxies, we find no worse performance of more complex MBS. However, we provide...

We develop a parsimonious price formation model to study information aggregation and information acquisition in the presence of trading delays. If delays apply uniformly to uninformed and informed traders, the level of delays does not affect information aggregation. Traders' information...

In this paper, the interactions between a large informed trader (IT, for short) and a high-frequency trader (HFT, for short) who can anticipate the former's incoming order are studied in an extended Kyle's model. Equilibria under various specific situations are discussed. We find that, in...

Social media has become a source of data on investor opinions but communication is itself an equilibrium outcome. Platforms are driven by interactions and this paper introduces these interactions to a model of trading under asymmetric information, which yields a communication strategy that does...

During the past decade, WeChat public accounts (WPAs) have gained increasing popularity as a novel tool for voluntary disclosure among Chinese public firms. This paper examines whether WPA disclosures provide value-relevant information to the market. Using a topic model to process over 1.6...

This paper studies how strategic interaction between players can influence their decisions as to whether to acquire information and whether to reveal their private information to others. We show how a player can increase his utility by disclosing part of his private information, when such...

Extreme adverse selection arises when private information has unbounded support, and market breakdown occurs when no trade is the only equilibrium outcome. We study extreme adverse selection via the limit behavior of a financial market as the support of private information converges to an...
