The time cost of information in financial markets

Chad Kendall ()

Journal of Economic Theory, 2018, vol. 176, issue C, 118-157

Abstract: I model a financial market in which traders acquire private information through time-consuming research. A time cost of information arises due to competition – through the expected adverse price movements due to others' trades – causing traders to rush to trade on weak information. This cost monotonically increases with asset value uncertainty, so that, exactly opposite to the result under the standard modeling assumption of a monetary cost of information, traders acquire the least information when this uncertainty is largest. The model makes several novel testable predictions regarding volume and order imbalances, some of which have existing empirical support.
