Odd lots are increasingly used in algorithmic and high-frequency trading, but are not reported to the consolidated tape or in databases such as TAQ.

We investigate the role of information-based trading in affecting asset returns. We show in a rational expectation example how private information affects equilibrium asset returns. Using a market microstructure model, we derive a measure of the probability of information-based trading, and we...

This paper investigates the effect on bank equity values of the Comptroller of the Currency's announcement that some banks were "too big to fail" and that for those banks total deposit insurance would be provided. Using an event study methodology, the authors find positive wealth effects...

The authors investigate the informational role of volume and its applicability for technical analysis. They develop a new equilibrium model in which aggregate supply is fixed and traders receive signals with differing quality. The authors show that volume provides information on information...
