Abstract

We develop a model of insider trading where agents have private information either about liquidation value or about supply, and behave strategically to maximize their profits. The presence of a supply-informed trader in the market induces non-monotonicity of market indicators with respect to the variance of liquidation value. Moreover, the existence of private information about supply affects significantly market performance as it induces, among other effects, lower market liquidity. Finally, our model suggests another link between Kyle's (1985, 1989) and Glosten and Milgrom's (1985) models by allowing for strategic behavior of an informed dealer.
