We study the effect of introducing an options market on investors' incentive to collect private information in a rational expectation equilibrium model. We show that an options market has two effects on information acquisition: a negative effect, as options act as substitutes for information,...

We propose a simple measure of investor sophistication based on financial statement experience derived from publicly available EDGAR log data about accounting information acquisition activity. This approach allows us to provide unique empirical evidence for the existence of attention induced...

We examine how information processing cost affects investors' acquisition of firm-specific information using a natural experiment resulting from a recent mandate that US firms be required to adopt the eXtensible Business Reporting Language (XBRL) when submitting filings to the SEC. XBRL filings...

I estimate the costs of information acquisition and the extent to which they explain stock anomaly returns. The SEC’s staggered implementation of EDGAR from 1993 to 1996 greatly lowered the costs of acquiring accounting information. I study how this quasi-exogenous and staggered shock affects...

This study examines how an increase in tick size affects algorithmic trading (AT), fundamental information acquisition (FIA), and the price discovery process around earnings announcements (EAs). Leveraging the SECs randomized Tick Size Pilot experiment, we show a tick size increase results in a...

We find that single-name options trading increases the absolute level of information content of prices (stock price informativeness). We confirm our results through instrumental variable approach to control for potential endogeneity. We further show causality by using a difference-in-difference...

The paper revisits and qualifies existing insights on security design. A rich literature argues that tranching creates debt-like instruments that are robust to adverse selection or discourage wasteful information acquisition. Yet, for a given information structure, while tranching confines and...

In the 1990s, companies collected billions in premiums from peculiarly structured put options written on their own stock while almost all of these puts expired worthless. Buyers of these options, primarily �nancial intermediaries, lost money as a result. Although these losses might seem...

We study the incentives to acquire information from exclusive news sources versus information from popular sources in a CARA-normal asset market. Each trader is able to observe one of a finite number of news sources. Clustering on the most precise source can happen for two reasons. One is...

This paper investigates the strategic interaction of information acquisition, information-based dynamic trading, and noise trading patterns, as well as its significant implications on market equilibrium outcomes. We consider a market where the strategic trader can dynamically acquire costly...
