Abstract

We study the impacts of shared information and price deviation from the semi-strong efficient condition on traders' trading behavior in the context of Kyle (1985)'s speculative market. We find that when the price is lower than the semi-strong efficient price, the insider and outsiders trade more aggressively using their private information, with a result that more information is incorporated into the price. Moreover, both the insider and outsiders prefer the price to be lower than the semi-strong efficient condition, whereas market makers prefer the price to be higher than the semi-efficient condition.
