We develop a dynamic model of order submission strategies in an order-driven market, where traders differ in their share valuations. Our model shows that several factors influence the uninformed trader¡¦s choice of order to submit: the market price, the expected asset value, the probability of...

The unmediated call auction is a useful trading mechanism to aggregate dispersed information. Its ability to incorporate information of a single informed insider, however, is less well understood. We analyse this question by presenting a simple call auction game where both auction prices and...

This paper develops a framework for the analysis of how asymmetric information impacts on adverse selection and market efficiency.  We adopt Akerlof's (1970) unit-demand model extended to a setting with multidimensional public and private information.  Adverse selection and efficiency are...

There has been a growing interest among policy makers on the use of information disclosure policies for pollution control. This paper theoretically assesses the consequences of information disclosure policies and identifies the conditions under which such policies are likely to bring...

Governments around the world are beginning to embrace a new form of environmental regulation – mandatory disclosure of information. While information disclosure programs appear to have an impact on subsequent firm behavior – often resulting in lower levels of pollution – little is known...

This paper examines incentives for information disclosure in a oligopolistic market when buyers are unsure of the existence of that information. Previous empirical and theoretical work has shown that mandatory disclosure laws can be binding when buyers do not know whether the information exists....

This paper studies an auction model in which one of the bidders, the insider, has better information about a common component of the value of the good for sale, than the other bidders, the outsiders. Our main result shows that the insider may have incentives to disclose her private information...

We find that a substantial portion of short sellers' trading advantage comes from their ability to analyze publicly available information. Using a database of short sales combined with a database of news releases, we show that the well-documented negative relation between short sales and future...
